The gray brocket deer, Mazama gouazoubira G. Fischer, 1814 , occurs in South America and presents an extensive degree of morphological and genetic variability. Previous phylogenetic research showed that the genus Mazama is polyphyletic and imposed the designation of a different genus-group name for M. gouazoubira. We aimed to review and clarify the taxonomy of M. gouazoubira through the proposal of updating the nomenclature for this taxon and by the characterization of specimens collected close to the original type locality (topotypes). The topotypes were characterized by morphological (general characterization and morphometry), cytogenetic (conventional staining, Ag-NOR, G- and C-banding, and fluorescence in situ hybridization), and phylogenetic (mitogenomes) approaches. We revealed chromosome homologies between cattle and M. gouazoubira using an entire set of cattle whole chromosome painting probes and propose an updated G-band idiogram for the species. The morphometric analysis did not discriminate the individuals of M. gouazoubira , including the topotypes, from other small brocket deer species. However, the phylogenetic analysis, based on a Bayesian inference tree of the mitogenomes, confirmed the polyphyly of the genus Mazama and supported the need to change the gray brocket deer genus-group name. Based on our revision, we validated the genus Subulo Smith, 1827 , and fixed a type species for the genus. In the absence of the holotype, we denominated a neotype described by the collection of a male topotype in Paraguay. The nomenclature rearrangement presented here is a starting point that will assist in the taxonomic resolution of Neotropical deer. [ABSTRACT FROM AUTHOR]

A new species of the genus Charinus Simon, 1892 is described from Santa Teresa District (1436 -1511 m of altitude), La Convención, Cusco, Peru, being this the third Charinus species from this region and the fifth one for this South American country. Its general feature and female gonopods greatly resembles Charinus longitarsus Armas & Palomino-Cardenas, 2016, and C. yanatile Palomino-Cardenas & Armas, 2022, from Cusco, too; but it differs from them by having 16 instead of 14 trichobothria in the distitibia of leg IV; on the other hand, in C. longitarsus the leg I has 30 tarsomeres (43 in the new species); whereas C. yanatiles has larger median ocular tubercle and the first tarsomere of leg I is longer than tarsomeres 1+2 joined. Also, the description of the female gonopods of C. longitarsus is emended and a taxonomic key for the identification of the Peruvian species of Charinus is given. [ABSTRACT FROM AUTHOR]

Chrysochlamys montieliae, a new species of the Clusiaceae family, Clusioideae subfamily, Clusieae tribe, from the Cordillera Azul National Park, Department of Loreto, is described and illustrated. Following the IUCN criteria, we propose to categorize it as Data Deficient (DD), since it is only known from the type locality. In addition, their relationships with related species are discussed.

A study on the taxonomic characters that have been used to discriminate the different species of the genus Bruchidius included in the unicolor group, represented in the Iberian-Balearic and Canary Islands fauna, is carried out. The taxonomic and biological heterogeneity of the species included in this group is discussed and some criteria are provided for characterization according this heterogeneity. The morphological analysis concludes with the low taxonomic value of its characters to differentiate the species, requiring the use of a set of characters. [ABSTRACT FROM AUTHOR]

El presente ensayo tiene el objetivo de explicar la importancia de la taxonomía revisada de Bloom, en la redacción de resultados de aprendizaje, para lo cual se plantean recomendaciones de su uso. En el documento se hace mención sobre la necesidad de generar propuestas educativas con mayor vinculación al contexto social, razón por la cual se han emitido políticas que promueven el diseño y la ejecución de planes de estudios centrados en el estudiantado. En este sentido, se aborda el trabajo desarrollado por autores como Kennedy (2006) y Biggs y Tang (2011) para la redacción de los resultados de aprendizaje. Finalmente, se desarrolla con un ejemplo, la coherencia que debe existir entre los resultados de aprendizaje, la evaluación y la implementación de las estrategias de enseñanza-aprendizaje, en el proceso formativo de la población estudiantil, entendido esto como el alineamiento constructivo. Se concluye que si bien las taxonomías son una guía que propone una clasificación jerárquica de los niveles de desarrollo de los procesos cognitivos y de conocimiento, su uso debe pasar de ser una tarea mecánica a un proceso de reflexión sobre el objeto de estudio de una disciplina académica. También, sobre la importancia de llevar a cabo el proceso de diseño de los resultados en equipos de trabajo, con la capacitación sobre su elaboración y el uso de las taxonomías, para lo cual la participación y acompañamiento de expertos en materia curricular se convierte en un requisito imprescindible.

Objective: This paper aimed to provide a systematic review of brand identity and understand how literature streams impact the current brand identity frameworks. Method: There are few systematic reviews about this salient topic, and the existing ones have not analyzed how the research in brand identity has evolved in the last 30 years, what have been the leading research streams and gaps, and which future avenues of study could be pursued. To fill this gap, this paper analyzed 67 articles published in 24 leading academic jour-nals (Academic Journal Guide grades 3, 4, and 4*) between 1990 and 2021. Main Results: Five key research streams were identified: brand identity frameworks; consumer behavior; corporate branding; visual brand iden-tity; co-creation. Despite the impressive progress made over the last 30 years, our review points out what we defined as a "middle-age brand identity crisis", since there is still no convergence among scholars about what brand identity is and what would be its main components. Also, the current research streams uncover concepts and ideas that were not previously included in brand identity frameworks. Relevance / Originality: This study performed a comprehensive systematic analysis of the brand identity literature, highlighting essential recent resear-ch not considered by the current brand identity frameworks and connecting it to branding constructs. We also identified that there is still a lack of con-sensus regarding the brand identity components and dimensions. Theoretical / Methodological Contributions: This paper contributes to the literature by presenting a new framework to shed light on the inte-ractions of brand identity with other branding constructs, proposing that brand identity has a core (brand essence) and extended identity (com-posed of personality, relationship, symbology, and cultural expressions). A new brand identity taxonomy is also proposed, with complexity and tangibility as its dimensions. [ABSTRACT FROM AUTHOR]

A new salamander species of the genus Bolitoglossa is here described from the cloud forests of the western slopes of the Cordillera Oriental of Colombia, in the Cundinamarca department. The most salient characters of this new species are its numerous maxillary and vomerine teeth, its moderate webbing on hands and feet, its short and robust tail, and its chromatic variation. Based on molecular analyses this new species is assigned to the adspersa species group and its status established as the sister species of B. adspersa, with which it was previously confused. Lastly, the distribution, natural history, and conservation status of the new species are discussed. [ABSTRACT FROM AUTHOR]

Thoroughly sampled and well-supported phylogenetic trees are essential to taxonomy and to guide studies of evolution and ecology. Despite extensive prior inquiry, a comprehensive tree of heron relationships (Aves: Ardeidae) has not yet been published. As a result, the classification of this family remains unstable, and their evolutionary history remains poorly studied. Here, we sample genome-wide ultraconserved elements (UCEs) and mitochondrial DNA sequences (mtDNA) of >90% of extant species to estimate heron phylogeny using a combination of maximum likelihood, coalescent, and Bayesian inference methods. The UCE and mtDNA trees are mostly concordant with one another, providing a topology that resolves relationships among the 5 heron subfamilies and indicates that the genera Gorsachius, Botaurus, Ardea, and Ixobrychus are not monophyletic. We also present the first genetic data from the Forest Bittern Zonerodius heliosylus, an enigmatic species of New Guinea; our results suggest that it is a member of the genus Ardeola and not the Tigrisomatinae (tiger herons), as previously thought. Finally, we compare molecular rates between heron clades in the UCE tree with those in previously constructed mtDNA and DNA--DNA hybridization trees. We show that rate variation in the UCE tree corroborates rate patterns in the previously constructed trees--that bitterns (Ixobrychus and Botaurus) evolved comparatively faster, and some tiger herons (Tigrisoma) and the Boat-billed Heron (Cochlearius) more slowly, than other heron taxa. Key words: herons, molecular rates, mtDNA, phylogenomics, taxonomy, UCEs [ABSTRACT FROM AUTHOR]

We describe Elaphoglossum auralolitae, a new species from southwestern Guatemala. The new species belongs to the Elaphoglossum petiolatum complex, in Elaphoglossum section Lepidoglossa, one of the largest sections within the genus. Elaphoglossum auralolitae is characterized by petioles and laminae densely scaly, with large scales including those of costae and margins; the presence of resinous dots on the petioles (mostly obscured by the scales) and on the abaxial laminar surface; and spores with spiny perispores. Only a dozen collections are known of this species so far, all of them from the Sierra Madre mountains in southwestern Guatemala. The first collection of this species was made in 1938 and the most recent was in 1992. We provide a description, taxonomic comments, geographic distribution, phenology, and illustrations for this new species. Describimos Elaphoglossum auralolitae, una especie nueva del suroeste de Guatemala. Esta especie forma parte del complejo de Elaphoglossum petiolatum, el cual hace parte de Elaphoglossum sección Lepidoglossa, una de las secciones más grandes dentro del género. Elaphoglossum auralolitae se caracteriza por pecíolos y láminas densamente escamosos, con escamas grandes, incluyendo las de la costa y las márgenes; presencia de puntos resinosos en los pecíolos (generalmente cubiertos por las escamas) y en la superficie laminar abaxial, y esporas con perisporas espinosas. Hasta el momento se conocen únicamente una docena de colecciones de esta especie, todas provenientes de la Sierra Madre en Guatemala. La primera colecta se realizó en 1938 y la más reciente en 1992. Este trabajo incluye la descripción e ilustración de esta nueva especie, imágenes de sus esporas, comentarios taxonómicos, distribución geográfica y fenología. [ABSTRACT FROM AUTHOR]

In the tropical Americas, the Orthosiinae (Apocynaceae) comprises plant species with small but intricate flowers and harbours a tremendous, still understudied diversity currently classified in four genera, Jobinia, Monsanima, Orthosia and Scyphostelma. In this study, we describe and illustrate four new species of Scyphostelma: S. bolivianum, S. gracile, S. rotorum and S. solomonii, based on specimens collected in Bolivia and Peru. Phylogenetic analysis places S. bolivianum and S. gracile in a clade with S. harlingii, a species from southern Ecuador and central Peru, together as sister clade to the rest of Scyphostelma. Due to the size of flowers and the long-filiform peduncles and pedicels, we consider the two new species S. rotorum and S. solomonii and the new combination S. erikseniae a part of the S. harlingii group, for which an identification key is presented. Furthermore, four species names are lectotypified and six new combinations in Scyphostelma are made: S. fasciculiflorum, S. jaramilloi, S. purpurascens, S. quitense, S. stenospira and S. unguiculatum.

En las Américas tropicales, Orthosiinae (Apocynaceae) comprende especies de plantas con flores pequeñas pero complejas y alberga una alta diversidad, aún poco estudiada, actualmente clasificada en cuatro géneros: Jobinia, Monsanima, Orthosia y Scyphostelma. En este estudio, describimos e ilustramos cuatro especies nuevas de Scyphostelma: S. bolivianum, S. gracile, S. rotorum y S. solomonii, con base en especímenes recolectados en Bolivia y Perú. El análisis filogenético ubica a S. bolivianum y S. gracile en un clado con S. harlingii, una especie del sur de Ecuador y el centro de Perú, juntas como clado hermano del resto de Scyphostelma. Debido al tamaño de las flores y a los pedúnculos y pedicelos filiformes largos, consideramos a las dos nuevas especies S. roturum y S. solomonii y la nueva combinación S. erikseniae una parte del grupo S. harlingii, para el cual se presenta una clave de identificación. Además, se lectotipifican cuatro nombres de especies y se realizan seis nuevas combinaciones en Scyphostelma: S. fasciculiflorum, S. jaramilloi, S. purpurascens, S. quitense, S. stenospira y S. unguiculatum.

Phenacorhamdia nigrolineata is redescribed, and the expansion of its geographic distribution is presented based on abundant new records. Morphological analysis, meristic comparison and osteological description were performed. No one autapomorphy was identified for P. nigrolineata, but the species is identified by an exclusive combination of characters of coloration of the body, morphometric and meristic data (snout length, maxillary and outer mental barbels length; number of vertebrae). A discussion of its geographic distribution, coloration pattern of the body, the putative relationships among some species of the genus, and its conservation status are presented.

Trichomycterid catfishes have long been considered as absent in the Parnaíba River basin, Northeastern Brazil, in what constitutes their most conspicuous gap in geographic distribution. Herein we report on the first occurrence of the family in that basin. The new species is described from the riacho da Volta, right tributary to the upper rio Parnaíba, Piauí State. It is distinguished from its congeners by the combination of two or three pairs of ribs; 36-38 post Weberian vertebrae; a color pattern composed of round, similar-sized, non-coalescent spots; I,5 pectoral-fin rays; the first haemal arch on the 5th or 6th vertebrae; and the first completely fused (to the tip) haemal spine on the 15th vertebra. A putative autapomorphy is the partial (minimally 50% of their length) or total fusion between the anterior arms of the basipterygium. Preliminary evidence suggests that the new species can be related to northern South American forms, a pattern that fits the general Amazonian relationships of the fishes in the Parnaíba River drainage. Although the new species fills in an important qualitative gap in trichomycterid continental distribution, the taxon is apparently rare and extremely restricted in distribution, with the type series being its only record so far. The paucity of trichomycterids in the Parnaíba remains a puzzling biogeographical phenomenon. [ABSTRACT FROM AUTHOR]

A new species of Corydoras is described from tributaries to the rio Araza, an affluent of the rio Inambari, itself a tributary to the rio Madre de Dios, rio Madeira basin in the Peruvian Amazon. The new species can be distinguished from its congeners by the following features: (I) absence of contact between the posterior process of the parieto-supraoccipital and the nuchal plate, (II) a single, large conspicuous dark brown or black blotch on anterodorsal portion of flank; blotch somewhat rounded to roughly diamond shaped, and (III) absence of dark blotches on fins. General comments on the identity of Corydoras aeneus are also provided. [ABSTRACT FROM AUTHOR]

A new species of the genus Fannia (Diptera: Fanniidae) is described, Fannia adelaidae sp. nov. This new species was collected in the Patagonian region in the province of Neuquén, within the Lanín National Park using baited traps. Photographs of diagnostic characters are provided for both sexes. Its possible phylogenetic relationship with other species of the same region is discussed. [ABSTRACT FROM AUTHOR]

The genus Epanycles Butler (Lepidoptera: Erebidae: Arctiinae: Ctenuchina) has been considered as monotypical for 145 years, including only Epanycles imperialis (Walker). Herein, we propose a new combination: E. satania new. comb. based on external morphology, genital morphology of males and females, morphological phylogeny, DNA barcoding, and geographical distribution. Epanycles satania was originally described for the genus Episcepsis Butler. [ABSTRACT FROM AUTHOR]

Thirteen species (18%) in the genus Dracula (Orchidaceae) in Colombia lack basic information about their ecology and biogeography. Dracula anthracina has remained as a charismatic market-valued species with no information on its natural habitat. We found the precise location of D. anthracina in explorations across the Colombian eastern Cordillera. Our observations of wild populations and cultivated plants suggest that D. nigritella should be reduced to a synonym of D. anthracina based on morphological characters. Furthermore, the species seems to be rare, geographically restricted, and has small populations. Hence, we suggest that D. anthracina should be considered of conservation concern and should be excluded from Ecuador's flora. Trece especies (18%) del género Dracula en Colombia carecen de información básica de su biogeográfica y ecológica. Dracula anthracina es una especie de alto valor en el mercado, cuya información del habito natural ha permanecido históricamente obscuro. Durante exploraciones de la orquideoflora de la cordillera oriental de Colombia, encontramos la ubicación de D. anthracina. Tras estudiar los caracteres morfológicos de individuos de D. anthracina en su hábitat natural y material cultivado, encontramos que D. nigritella debe ser reducido a sinónimo de D. anthracina. Nuestro muestreo aleatorio sugiere que esta Dracula es rara, con distribución geográfica restringida y poblaciones pequeñas. De tal manera, D. anthracina como especie comercializada debe ser considerada como una especie de conservación endémica de Colombia y debe ser excluida de la flora de Ecuador. [ABSTRACT FROM AUTHOR]

Lotic environments are subjected to the impacts of human activities in an intense way in urban regions and one of the ways to assist in the environmental diagnosis is through the knowledge of the composition of bioindicator organisms, including microalgae. The objective of this work was to qualitatively characterize the Chlorophyceae Class Wille, providing descriptions and meristic data of the specimens as well as the environmental conditions in which the taxa were recorded. Water and phytoplankton samplings were carried out quarterly in 2020, in nine supply rivers, distributed in three river basins in the western region of Paraná (Paraná III basin, Piquiri basin and Baixo Iguaçu basin). The studied rivers were classified as oligotrophic or mesotrophic and the taxa were mostly rare. Thirty-six taxa belonging to the Chlorophyceae class were recorded, distributed in five families: Hydrodictyaceae Dumortier, Neochloridaceae Ettl & Komárek, Radiococcaceae Fott ex P.C.Silva, Scenedesmaceae Oltmanns, Selenastraceae Blackman & Tansley. These taxa have mainly cenobial representatives, with about 70% of the individuals in this thallus configuration, followed by 22% colonies and 8% unicellular thallus. Among the identified species, five occurred only in mesotrophic sites, warning for environments with tendencies to elevate their trophic, since they are genera previously associated with these conditions. Ten new citations were recorded for the State of Paraná, namely: Pseudopediastrum boryanum var. longicorne (Reinsch) P.M.Tsarenko, Radiococcus skujae I.Kostikov, T.Darienko, A.Lukesová & L.Hoffmann, Desmodesmus perforatus (Lemmermann) E.Hegewald, Desmodesmus subspicatus (Chodat) E.Hegewald & A.W.F.Schmidt, Scenedesmus indicus Philipose ex Hegewald, Engelberg & Paschma, Ankistrodesmus bernardii Komárek, Monoraphidium capricornutum (Printz) Nygaard, Monoraphidium caribeum Hindák, Raphidocelis danubiana var. elegans (Playfair) Taşkin & Alp, Selenastrum rinoi Komárek & Comas. Taxonomic studies, such as this one, are an important tool for understanding the flora, and in addition to contributing to the registration of species in aquatic ecosystems, they serve as a basis for ecological studies and other approaches used to preserve biodiversity in these places.

Several individuals of free-living copepods were found in tap water of the Unidad Académica Mazatlán (Instituto de Ciencias del Mar y Limnología). These copepods turned out to belong to a new species of the freshwater genus Paracyclops. Paracyclops poppei , P. hirsutus , and P. chiltoni were the only species reported in Mexican freshwater ecosystems, and the record of P. fiersi sp. nov. is the fourth confirmed species of the genus from Mexico. The new species seems to be related to P. hardingi and P. bromeliacola. The new species differs in the ornamentation of the female antennary coxobasis, and in the posterior, subdistal, medial spinules on the coxa of the first–fourth leg in both sexes. The city of Mazatlan is supplied with groundwater from an aquifer of the Presidio River (south of Mazatlan), and the new species is most probably distributed in the southern state of Sinaloa (north-western Mexico).

Se examinaron los caracteres morfológicos y moleculares del género Dysopsis para una reevaluación de las especies, lo que permitió tener una mejor definición de los taxones. D. chilensis, una especie considerada por mucho tiempo como sinónimo de D. glechomoides se restablece, por lo cual ahora el género está formado por cuatro especies. Se designó el lectotipo para tres especies. Además, se elaboraron las descripciones de las especies del género y una clave para separarlas.

Introducción y objetivos: Zephyranthes bifida (Amaryllidaceae) fue incluida recientemente como única especie polimórfica del subgénero Neorhodophiala. Su historia taxonómica no ha sido reseñada, pudiendo tratarse de un aporte valioso para dilucidar el posible complejo de especies que sugiere la gran variación morfológica observada en su amplio rango de distribución. El presente trabajo tiene como objetivo presentar la historia taxonómica de Z. bifida con la lista completa de sinónimos, junto con algunas observaciones morfológicas. M&M: Se consultaron publicaciones originales, floras y bases de datos digitales. Se elaboró una tabla con la lista completa de sinónimos en la que se incluyó para cada uno, el nombre científico, año y referencia de la publicación, tipo de evento taxonómico y sus sinónimos. En el marco de estudios morfométricos realizados con individuos adultos de ocho poblaciones de la provincia de Buenos Aires, se encontraron ciertas medidas de caracteres que resultaron novedosas al compararlas con las descripciones de Z. bifida. Resultados y conclusiones: Se registraron 49 eventos taxonómicos. A partir del estudio realizado, se propone incluir dos sinónimos nuevos para Z. bifida y reconocer un nombre como ilegítimo, de modo que actualmente se asocia con 43 sinónimos legítimos, tres nombres ilegítimos y dos isónimos sin estatus nomenclatural. El seguimiento de ejemplares cultivados permitió observar que un mismo bulbo puede generar inflorescencias con los dos tipos de espata, descartándose la hipótesis de que esta variable morfológica podría corresponder a taxones diferentes.

En Argentina la diversidad real de la familia Geometridae está muy subestimada como consecuencia de muestreos insuficientes y estudios fragmentados. Dentro de géneros muy diversos como Macaria (Curtis, 1832), que incluye alrededor de 330 especies y subespecies con patrones de coloración similares, subyace la existencia potencial de especies desconocidas. Se describe e ilustra una nueva especie para el género Macaria en Argentina, en base a ejemplares colectados en la ciudad de Garupá, Misiones. La morfología genital del macho y el patrón de coloración alar de Macaria garupa sp. nov. acercan a esta especie a Macaria rigidata Guenée, [1858], pero los caracteres diagnósticos de la nueva especie permiten separarlas fácilmente. Los estados inmaduros de M. garupa están asociados a Duranta erecta L (1758) (Verbenaceae). La importancia de este trabajo radica en la descripción de una nueva especie perteneciente a un género poco estudiado en la región, caracterización de su historia natural y determinación de su nivel de sinantropía.

RESUMO A Ilha de São Luís, Estado do Maranhão, configura-se como uma região ecotonal, um misto de floresta úmida, mata-de-cocais, vegetação de dunas, restingas e manguezais. Diferentemente do interior do Estado do Maranhão, suas zonas costeiras possuem uma lacuna sobre o conhecimento da família Passifloraceae. Aqui, por meio de expedições de campo e consulta a herbários, nós fornecemos o tratamento taxonômico, chave de identificação e comentários sobre as Passifloraceae da Ilha de São Luís. Foram registradas dez espécies: Passiflora auriculata Kunth, P. edulis Sims, P. foetida L., P. glandulosa Cav., P. laurifolia L., P. misera Kunth, P. nitida Kunth, P. picturata Ker Gawl., P. subrotunda Mast. e P. vespertilio L. As espécies P. picturata e P. misera foram registradas pela primeira vez na Ilha de São Luís.

RESUMO Levantamento florístico do gênero Ulothrix (Ulotrichaceae, Chlorophyceae) no Estado de São Paulo, sudeste do Brasil. Foram identificadas cinco espécies com base em sua morfologia celular externa e interna, descritas em detalhes e ilustradas. Ulothrix tenerrima e U. tenuissima ocorreram em quatro municípios cada uma, U. aequalis var. aequalis f. aequalis em três, U. zonata em dois, e U. subtilissima apenas em um município; U. tenuissima foi presentemente citada pela primeira vez para o Estado de São Paulo.

RESUMO A descrição da nova espécie para o Brasil, Cheilolejeunea savannae L.P. Macedo, Ilk.-Borg. & C.J. Bastos, suscitou a necessidade de rever muitos espécimes identificados previamente como Cheilolejeunea intertexta (Lindenb.) Steph., objetivando o refinamento do conceito desta espécie e a sua real distribuição no Brasil. O presente estudo também resultou no restabelecimento de Cheilolejeunea compacta (Steph.) M.E. Reiner, previamente considerada como sinônimo de C. intertexta, como táxon distinto. Foi demonstrado, também, que C. savannae tem distribuição mais ampla no Brasil e especialmente no Estado da Bahia, comparativamente à C. intertexta e C. compacta. Descrições e uma chave para a separação das três espécies aqui reconhecidas são apresentadas.

Apresenta-se o levantamento florístico de samambaias e licófitas em duas áreas de Floresta Ombrófila Densa, no município de Pilar do Sul, estado de São Paulo, seus aspectos ecológicos e uma chave para a identificação das espécies. Os remanescentes de vegetação estudados encontram-se inseridos em matriz silvicultural (Eucalyptus spp.), localizados às margens de cursos d’água, são secundários e, em sua maioria, em estágio médio de regeneração natural. Para as duas áreas foram registradas 112 espécies, distribuídas em 61 gêneros e 20 famílias. As famílias Polypodiaceae, Dryopteridaceae e Thelypteridaceae foram as mais representativas, assim como os gêneros Amauropelta, Cyathea e Pteris. As espécies herbáceas e terrícolas foram as mais comuns entre as formas de vida e substrato, bem como as espécies neotropicais foram mais frequentes em relação à distribuição geográfica. Portanto, mesmo áreas secundárias, circundadas por matriz antrópica, podem abrigar um elevado número de espécies de samambaias e licófitas. A proteção e conservação destes remanescentes são importantes para a sobrevivência destas populações.

Se presenta una taxonomía de usos y dos matrices donde se relacionan los usos y recursos. Los usos son biológicos, hidrológicos, descarga de efluentes, investigaciones, poblacionales y recreacionales. Los hidrológicos presentan un elevado grado de interrelación con los demás, lo cual indica el gran peso que tienen en las actividades que se desarrollan en la zona costera. Esta interrelación casos puede ser peligrosa sobre los recursos. Estos son hídricos, agricultura, meliferos madereros pesqueros y ecosistemas. La pesquería se encuentra afectada por un conjunto de factores entre los que se citan, el aumento en la capacidad de agua embalsada, la disminución de los fertilizantes, el incremento del esfuerzo pesquero y el no cumplimiento de regulaciones pesqueras. Esta situación se agrava por el efecto de ciclones tropicales y la afectación posterior que trajeron en el reclutamiento y en las áreas de cría. La combinación de estos elementos debe haber perturbado la capacidad de carga de los ecosistemas de la región y de resiliencia de la población.
