Temporary ponds are small‐sized limnic systems that dry periodically. The length of the wet phase defines the hydroregime and determines community assembly in temporary ponds. Zooplankton species have adapted to desiccation by adopting some dormant strategies, such as the formation of resting stages. Hatching from resting stages is a source of recolonization after drought events and the composition of hatching taxa is also influenced by hydroregime. We compared metacommunity structure and composition of the dormant sub‐community (resting stages); the pioneer active sub‐community (fauna present immediately after inundation of ponds); and the cumulative active sub‐community (fauna present at the initial, middle and final phases of hydroperiod) in a set of temporary ponds with semipermanent and seasonal hydroregimes in two areas with mediterranean climate: central Chile and eastern Spain. We aimed to determine the influence of hydroregime and identify whether metacommunity patterns are consistent between regions sharing a mediterranean climate.We selected five semipermanent and five seasonal ponds in each region to sample sediments and active zooplankton sub‐communities. By combining hatching experiments from the sediments with direct counts of active zooplankton from the field samples, we gathered data on both dormant and active sub‐communities to build unweighted bipartite networks of species occurrences in each pond. The obtained networks were analysed to determine seasonal trends in structural features of the metacommunities (diversity, nestedness and modularity) and their relation to hydroregime (semipermanent and seasonal) and geographical location (Chile and Spain).We observed consistent differences in community structure when comparing sub‐communities at different successional stages (dormant, pioneer active and cumulative active) and with different hydroregimes (semipermanent vs. seasonal). Both α‐ and γ‐diversity showed a consistent trend, being highest in cumulative active sub‐communities and lowest in dormant ones, and were consistently higher in seasonal ponds, regardless of the region. In addition, β‐diversity was higher in the pioneer active sub‐community in both regions, with no significant differences between hydroregimes. The species composition of cumulative active sub‐communities were less heterogeneous than that of the pioneer and dormant ones. No consistent patterns were found in modularity and nestedness values across sub‐communities and hydroregimes.In agreement with our hypotheses, we observed a gradual accumulation of taxa as well as community homogenization over time in both regions. Contrary to our expectations, hydroregime did not affect these patterns and, surprisingly, shorter hydroperiods exhibited higher regional diversity. Our results suggest that hydroregime as a single variable does not have a strong explanatory power for metacommunity assembly of temporary ponds. Therefore, a more comprehensive theory is needed to anticipate the effects of the upcoming hydroperiod shortening. [ABSTRACT FROM AUTHOR]

- Abstract
Volcanic eruptions are key drivers of climate variability, with complex environmental consequences at regional and local scales that are rarely documented in high-resolution sedimentary records. In this work we present the results of a 15 m long paleolake core (Pla de les Preses core, Vall d’en Bas, Girona, NE Spain) covering the Late Pleistocene-Holocene transition. Multiproxy analyses including chronostratigraphy, sedimentology, micropalaeontology and geochemistry are used to reconstruct the paleoenvironmental framework of the Late Pleistocene-Holocene transition and to detect the youngest Holocene volcanic eruptions in the Garrotxa Volcanic Field (GVF) and the Iberian Peninsula. The studied sedimentary record covers the last ca. 13.5 ka cal BP and was punctuated by several rapid climatic changes including the 9.3, 8.2 and 7.1 ka events, affecting the hydrological evolution of a barrier-lake formed due to the volcanic damming of the Fluvià river. Sedimentological and geochemical analyses unveil the environmental history of Vall d’en Bas valley; the formation of a lacustrine area within a fluvial environment around 13.5 ka cal BP and later a wetland phase between 9.3 and 8.2 ka cal BP. Abrupt sedimentary changes marking the onset and demise of the wetland phase were linked to hemispheric cooling and drying events (e.g. 9.3 and 8.2 ka cal BP), provoking a decline in the water table during these phases. In addition, 30 tephra layers are detected thorough the core, showing previously unknown intense volcanic activity from 13.5 to 8.3 ka cal BP in the GVF. In that sense, the Pla de les Preses sequence provides, for the first time, evidence for early Holocene volcanic activity in NE Iberia that should be taken into account in future tephra studies in the western Mediterranean realm.

PONDS ,CRONBACH'S alpha ,BIOTIC communities - Abstract
The latitudinal diversity gradient predicts that tropical regions should have higher alpha, beta, and gamma diversity than temperate areas. However, only a few studies have assessed the temporal variability of the different components of diversity across climatic regions. In this study, we compare, using a spatial and temporal approach, the diversity of multiple taxa inhabiting tropical and Mediterranean temporary ponds. We sampled the biological communities of each set of ponds on three occasions during the same hydrological year. Under a spatial framework, we analyzed, alpha, beta, and gamma diversities. With a temporal approach, we compared the coefficients of variation in alpha diversity for each local community, and temporal beta diversity. Differences between regions and sampling periods were tested using generalized linear mixed models. We found higher gamma and alpha diversity in the tropical ponds, as expected given the latitudinal differences between them. However, phytoplankton and microinvertebrates from the Mediterranean region, matched or even exceeded tropical alpha diversity on some occasions. Spatial beta diversity did not differ between regions, and it showed lower values at the middle or the end of the hydroperiod in bacteria, micro‐ and macroinvertebrates and amphibians. Thus, processes homogenizing and heterogenising pond metacommunities must be balanced in both studied regions. Temporal variation in alpha and beta diversity was similar for ponds in both regions, except for macroinvertebrates and amphibians, suggesting differential effects on community variation observable only in animals with longer life‐spans, at our temporal scale of analysis.

Especialistas de los distintos grupos faunísticos capaces de colonizar las cuevas y las aguas subterráneas que las recorren. Hoy sabemos que esta diversidad de troglobios y estigobios alcanza un total de 1364 taxones: 1285 especies y 79 subespecies hipogeas (cavernícolas) pertenecientes a cuatro filos: Plathyhelminthes (2), Annelida (23), Mollusca (122) y Arthropoda (1217) en todo el territorio ibero-balear. Una fauna que cuenta con numerosos ejemplos de elementos relictos de especial interés paleogeográfico. De la totalidad de taxones hipogeos o cavernícolas del territorio ibero balear, 438 taxones (430 especies y 8 subespecies) son estigobios y 926 taxones (852 especies y 74 subespecies) son troglobios. En lo referente a la distribución de los taxones troglobios es el distrito Cantábrico el que posee una mayor riqueza en especies y subespecies, un total de 208, seguido del Vasco con 163 taxones, el Pirenaico con 153 y el Bético con 142. Algo menos diversos son los distritos Levantino (124 taxones) y Catalán (104 taxones), seguidos de lejos por el Lusitánico con 46 taxones, el Balear con 41 y el Central con tan sólo 19. Entre los estigobios 156 especies y subespecies pueblan las aguas subterráneas de las regiones delimitadas por las cuecas lusitánicas. Le siguen en diversidad las cuencas pirenaicas con 154 taxones estigobios, las béticas con 114 y por último las aguas del subsuelo de las cuencas baleáricas con 47 taxones estigobios, algunos de los cuales son talaso-estigobios, propios de las aguas marinas costeras, [EN] The Iberian-Balearic hypogean or cave fauna has been highlighted for many years by numerous zoologists in different disciplines.

Many aquatic invertebrates that inhabit temporary ponds produce resting forms to overcome the dry period, building up the egg bank. When the wet phase returns, the resting forms hatch and the community is restored, and then pioneer species may have a major influence on how the pond community will assemble. We aimed to evaluate the diversity of an initial pond metacommunity by comparing the early active metacommunity collected in the field and the egg bank metacommunity (by carrying out a hatching experiment) of 32 Mediterranean temporary ponds. We hypothesised that both metacommunities would be similar but also that species turnover may play an important role, and that γ diversity would be similar with both approaches.After the identification and counting of rotifers and crustaceans in both metacommunities (i.e. the field vs. the experiment) we performed a Partial Triadic Analysis comparing the field metacommunity with those corresponding to each of the eight times the hatching experiment was checked for hatchlings. Furthermore, we compared the field and experimental metacommunities with a PROTEST analysis and identified the taxa responsible for differences between metacommunities with a SIMPER analysis. We assessed γ diversity using a size‐based rarefaction curve and an evenness profile and explored β diversity and its components (turnover and nestedness) for the two metacommunities.Our experimental results showed differences in the temporal pattern of emergence between groups of organisms, with copepods, rotifers, and anostracans appearing first, but ostracods and rotifers reaching the highest diversity at the end of the experiment. The active and experimental pioneer metacommunities were similar according to a Procrustes analysis. Nevertheless, β diversity was high in both metacommunities and the differences among ponds and between both assemblages were mostly explained by species turnover.Both the active and experimental pond metacommunities showed some exclusive species that may be more difficult to uncover with only one type of approach. Furthermore, the high β diversity observed indicates that each temporary pond is an important contributor to γ diversity in the metacommunity.These results show that hatching experiments provide information that is complementary to standard sampling of the active community, and consequently is a useful tool to uncover pond biodiversity.

The metacommunity concept provides a theoretical framework that aims at explaining organism distributions by a combination of environmental filtering, dispersal, and drift. However, few works have attempted a multitaxon approach and even fewer have compared two distant biogeographical regions using the same methodology. We tested the expectation that temperate (mediterranean‐climate) pond metacommunities would be more influenced by environmental and spatial processes than tropical ones, because of stronger environmental gradients and a greater isolation of waterbodies. However, the pattern should be different among groups of organisms depending on their dispersal abilities. We surveyed 30 tropical and 32 mediterranean temporary ponds from Costa Rica and Spain, respectively, and obtained data on 49 environmental variables. We characterized the biological communities of bacteria and archaea (from the water column and the sediments), phytoplankton, zooplankton, benthic invertebrates, amphibians and birds, and estimated the relative role of space and environment on metacommunity organization for each group and region, by means of variation partitioning using generalized additive models. Purely environmental effects were important in both tropical and mediterranean ponds, but stronger in the latter, probably due to their larger limnological heterogeneity. Spatially correlated environment and pure spatial effects were greater in the tropics, related to higher climatic heterogeneity and dispersal processes (e.g., restriction, surplus) acting at different scales. The variability between taxonomic groups in the contribution of spatial and environmental factors to metacommunity variation was very wide, but higher in active, compared with passive, dispersers. Higher environmental effects were observed in mediterranean passive dispersers, and higher spatial effects in tropical passive dispersers. The unexplained variation was larger in the tropical setting, suggesting a higher role for stochastic processes, unmeasured environmental factors, or biotic interactions in the tropics, although this difference affected some actively dispersing groups (insects and birds) more than passive dispersers. These results, despite our limitations in comparing only two regions, provide support, for a wide variety of aquatic organisms, for the classic view of stronger abiotic niche constraints in temperate areas compared with the tropics. The heterogeneous response of taxonomic groups between regions also points to a stronger influence of regional context than organism adaptations on metacommunity organization. [ABSTRACT FROM AUTHOR]

The main diagnostic features of the species are the presence of marginal septa, presence of Wouters organ on the first antenna, strongly serrated claw G2 of the second antenna (A2), small β seta on the mandibular palp, elongated terminal segment of the maxillular palp, smooth and large bristles on the third endite of the maxillula, undivided penultimate segment of the second thoracopod (T2), absence of d1 seta on the T2, completely separated terminal segment of the third thoracopod, absence of a pincer organ, and reduced caudal ramus with a triangular base. The taxonomic position of Pseudocypretta Klie, 1932 is also revised. Based on molecular analysis using the cytochrome c oxidase subunit I (COI), Pseudocypretta appears closer to Cypridopsinae Kaufmann, 1900 than to Cyprettinae Hartmann, 1971. This result is congruent with morphological evidence and, among other cypridopsine genera, Pseudocypretta shows highest similarity with Cyprettadopsis Savatenalinton, 2020 given its reduced caudal ramus, the strongly serrated claw G2 of the A2, absence of pincer organ, and presence of marginal septa. Pseudocypretta is therefore allocated to the tribe Cyprettadopsini Savatenalinton, 2020. [ABSTRACT FROM AUTHOR]

Las almejas de agua dulce o náyades son uno de los grupos faunísticos más amenazados del planeta. Entre ellos, la almeja gigante del Ebro o náyade auriculada (Pseudunio auricularius, Spengler 1793) es el bivalvo unionido más amenazado de Europa, y la población de la cuenca del río Ebro en España se encuentra en una situación crítica. El objetivo de esta tesis es aumentar el conocimiento científico del estado de conservación actual de la especie en España con el fin de aplicar acciones de gestión significativas para reducir su riesgo de extinción. El descenso de las poblaciones de náyades (Orden Unionida) en la cuenca del Ebro es generalizado, pero la situación en los canales asociados es crítica, especialmente desde 2013 cuando se registró un episodio de mortalidad masiva de P. auricularius en el Canal Imperial de Aragón (CIA). En el marco de un estudio a largo plazo con el objetivo de evaluar las densidades de náyades en los canales, los resultados obtenidos mostraron una disminución continua y generalizada de todas las especies nativas, que terminó con la extinción local de Anodonta anatina (Linnaeus, 1758), Potomida littoralis ( Cuvier, 1798) y Unio mancus Lamarck, 1819, junto con miles de ejemplares muertos de P. auricularius. Una posible explicación de estas disminuciones es el envejecimiento y la posible muerte debido a la senescencia. Para conocer la relación entre la longitud de la concha y la edad en P. auricularius en la cuenca del Ebro, se analizó su patrón de crecimiento mediante el conteo de anillos de concha de ejemplares adultos y jóvenes junto con datos de crecimiento de juveniles criados en cautividad. Los modelos sigmoidales generalizados de von Bertalanffy y Richards presentaron el mejor ajuste, mostrando que la tasa de crecimiento de P. auricularius es relativamente lenta después de los 30 años, cuando se alcanza el máximo crecimiento. La edad máxima estimada para un ejemplar en la cuenca del Ebro fue de 68 años. Otra posible explicación de la disminución de la población fue la contaminación ambiental derivada de las actividades antropogénicas. Considerando la falta de conocimiento previo sobre la sensibilidad de la especie, se realizaron por primera vez pruebas de toxicidad aguda contra metales pesados y amonio utilizando juveniles de la cría en cautividad. De esta forma, se determinaron los valores de concentración letal (CL50 y CL10) para cadmio, cobre, níquel, zinc, cromo, plomo y amonio. Además, se evaluaron los valores de la concentración sin efecto no observado (NOEC), los valores de concentración de efecto mínimo observado (LOEC) y las concentraciones tóxicas máximas aceptables (MATC) para cada contaminante probado. Al comparar los resultados de P. auricularius con los datos disponibles de otras especies de náyades, parece ser más sensible al cadmio y al cobre, y menos sensible al níquel, el plomo y el amoníaco total. Como una de las principales acciones previstas para la recuperación de la especie, se establecieron cultivos de laboratorio para desarrollar un protocolo de cría en cautividad de juveniles de P. auricularius. Se probaron los efectos de varias condiciones sobre la supervivencia y el crecimiento. Los mejores resultados correspondieron a un tratamiento en recipientes de vidrio, a una densidad de 0,2 ind/L, utilizando agua del mismo río Ebro, sustrato, detritus y fitoplancton, y sin aireación extra. Las tasas más altas de supervivencia y crecimiento alcanzadas fueron del 60 % a los 100 días y una longitud de concha de 2,56 mm a las 30-32 semanas de vida. La cría en cautividad se considera una de las herramientas de gestión más importantes para mejorar el estado de conservación de P. auricularius, y estos valiosos resultados permiten establecer, por primera vez, las mejores condiciones para maximizar la supervivencia de los juveniles en condiciones de laboratorio. Finalmente, y con el objetivo de aumentar las probabilidades de supervivencia de los ejemplares en el CIA, en 2017 se inició un plan de translocación. Los ejemplares adultos fueron traslocados desde el CIA al río Ebro utilizando parcelas previamente caracterizadas como aptas para la supervivencia de P. .auricularius. Se traslocaron un total de 638 especímenes (291 especímenes en 2017, 291 en 2018 y 56 en 2019). La monitorización, un año después, permitió estimar una tasa de supervivencia entre el 40 y el 70%. Por otro lado, el grupo de control que quedó en la CIA tuvo una tasa de supervivencia más baja de solo el 19,7% después de un año. En base en estos primeros resultados, se confirmó que los ejemplares de P. auricularius trasladados al cauce principal del río mostraron una mayor supervivencia que los que permanecieron en el canal. En general, la información generada servirá de apoyo para la aplicación de las mejores medidas de restauración con el fin de frenar la curva de declive de esta icónica especie ribereña en España. Freshwater mussels are one of the most threatened faunal groups in the planet. Among them, the Giant Freshwater Pearl mussel (Pseudunio auricularius, Spengler 1793) is the most endangered unionid bivalve in Europe, and the population of the Ebro River basin in Spain is in a critical situation. The aim of this thesis is to increase the scientific knowledge of the current conservation status of the species in Spain in order to apply meaningful management actions to reduce its risk of extinction. The decline of freshwater mussel (Order Unionida) populations in the Ebro basin is widespread, but the situation in the associated canals is critical, especially since 2013 when an episode of mass mortality of P. auricularius in the Canal Imperial de Aragón (CIA) was recorded. In the framework of a long-term study aiming to assess mussel densities in the canals, the obtained results showed a continued and generalized decrease of all native mussel species, ending with the local extinction of Anodonta anatina (Linnaeus, 1758), Potomida littoralis (Cuvier, 1798) and Unio mancus Lamarck, 1819, together with thousands of P. auricularius' dead specimens. One possible explanation for these declines is aging and possible death due to senescence. To find out the relationship between shell length and age in P. auricularius in the Ebro basin, its growth pattern was analysed by counting the shell rings of adult and young specimens together with growth data of captive-bred juveniles. The generalized von Bertalanffy and Richards sigmoidal models presented the best fit, showing that the growth rate of P. auricularius is relatively slow after 30 years, when maximum growth is reached. The maximum age estimated for a specimen in the Ebro basin was 68 years. Another possible explanation of the population decline was environmental pollution derived from anthropogenic activities. Considering the lack of previous knowledge on the species' sensitivity, acute toxicity tests against heavy metals and ammonium were carried out for the first time using juveniles from a captive breeding program. In this way, the lethal concentration values (LC50 and LC10) were determined for cadmium, copper, nickel, zinc, chromium, lead and ammonium. In addition, non-observed-effect concentration (NOEC) values, lowest-observed-effect concentration (LOEC) values and maximum acceptable toxicant concentrations (MATC) were assessed for each contaminant tested. When comparing the results of P. auricularius with available data from other mussel species, it seems to be more sensitive to cadmium and copper, and less sensitive to nickel, lead, and total ammonia. As one of the main actions planned for the recovery of the species, laboratory cultures were established to develop a captive breeding protocol for juveniles of P. auricularius, by testing the effects of several conditions on survival and growth. The best results corresponded to a treatment in glass containers at a density of 0.2 ind/L, using river water, substrate, detritus and phytoplankton, and without extra aeration. The highest survival and growth rates achieved were 60% at 100 days and 2.56 mm shell length at 30-32 weeks of life. Captive breeding is considered one of the most important management tools to improve the conservation status of P. auricularius, and these valuable results allow establishing, for the first time, the best conditions for maximizing juvenile survival under laboratory conditions. Finally, and with the objective of increasing the survival probabilities of the living specimens left in the CIA, a translocation plan was initiated in 2017. Adult specimens were translocated from the CIA to the Ebro River using plots previously characterized as suitable for the survival of P. auricularius. A total of 638 specimens (291 specimens in 2017, 291 in 2018, and 56 in 2019) were translocated. A monitoring survey, one year after, allowed estimating a survival rate between 40 and 70%. On the other hand, the control group left in the CIA had a lower survival rate of just 19.7% after one year. Based on these first results, it was confirmed that the specimens of P. auricularius translocated to the main river channel showed higher survival than those that remained in the canal. Overall, the autecological information collected will provide support for the application of the best restoration measures in order to bend the curve of decline of this iconic riverine species in Spain.

- Abstract
The two widespread ostracod genera Cypria Zenker, 1854 and Physocypria Vávra, 1897 are traditionally distinguished based on the presence or absence of tubercles on the right valve margin. However, recent research based on soft body parts has uncovered new cryptic genera within Cypria and Physocypria . Following this line of research, a new Cyclocyprididae genus and species, Vizcainocypria viator gen. nov. sp. nov., is here described from individuals collected in rice fields and wetlands of the Iberian Peninsula. Vizcainocypria is compared with Cypria , Physocypria , Dentocypria Savatenalinton, 2017, Keysercypria Karanovic, 2011, Brasilocypria Almeida et al., 2023, and Claudecypria Almeida et al., 2023 based on morphological evidence. Besides the presence or absence of tubercles on the right valve, these genera can be distinguished according to their mandibular palp, second thoracopod, caudal ramus, and male hemipenis. Molecular analyses using mitochondrial (COX1), and nuclear (28S rDNA) genes provide further support for the differentiation of Cypria , Dentocypria , Physocypria and Vizcainocypria gen. nov. The present study highlights the importance of using an integrative taxonomy approach, combining shell and soft-body parts morphology and molecular data, to characterize the rich diversity of freshwater ostracods.
