Abstract

Several fish-marking techniques are used to diagnose the population dynamics of species. However, marks should not interfere with behavior, growth and reproduction of the involved population. For this reason, VIFE (Visible Implant Fluorescent Elastomer) was developed. This study reports the use of VIFE to mark two small tropical species, Bryconamericus iheringii and Rineloricaria malabarbai, in a controlled environment. We captured 30 individuals of B. iheringii and 30 of R. malabarbai by electrofishing. The fish were marked and observed for 90 days, and there was no instant mortality after inserting the elastomer. During the first 70 days there was low mortality and high retention rates, but many elastomers broke into smaller fragments. Based on the low mortality and high retention rates found in this analysis, the use of VIFE is recommended for similar studies.

Abstract

Algumas técnicas de marcação de peixes são utilizadas para diagnosticar aspectos da dinâmica populacional das espécies, não podendo interferir no comportamento, crescimento e reprodução da população envolvida. O presente estudo visa reportar a utilização do VIFE (Visible Implant Fluorescent Elastomer) na marcação de duas espécies de peixes de pequeno porte em ambiente controlado. O objetivo foi investigar se a mortalidade, a fragmentação e retenção da marca são indicadores da eficiência do implante. Foram marcados 60 peixes, 30 indivíduos do caracídeo Bryconamericus iheringii e 30 indivíduos do loricarídeo Rineloricaria malabarbai. Após 70 dias de experimento, os indivíduos de ambas as espécies não apresentaram crescimento e a taxa de retenção e mortalidade foi baixa. Existiu um grande numero de fragmentações devido à posição onde as marcas foram inseridas no corpo dos peixes. Após 90 dias de experimento todos os peixes morreram devido à contaminação da água. Os resultados de baixa mortalidade e retenção determinam que o uso de VIFE é recomendado.

Abstract

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications.

Abstract

Changes in landscape composition caused by conversion of natural habitats into human-altered ecosystems can directly influence the physical characteristics of stream networks. Such impacts can modify the functional structure of fish communities, although the exact consequences of anthropic land-use changes can be context-dependent. This study investigated the influence of different land-use classes on the functional structure of fish communities in 32 headwater streams from southern Brazil. Trait composition and indices of functional diversity of the fish community were related to four land-use classes: native forest vegetation, silviculture, agriculture, and urban areas. Streams surrounded by larger areas of native forest were characterized by the predominance of foraging specialist species like grazers. However, as native vegetation is replaced by agriculture and urban areas, specialist species are replaced by species with generalist diet like detritivores. In streams surrounded by larger areas of agriculture, functional richness and divergence increased, while functional evenness decreased. Most likely, these changes were induced by alterations in the water quality, indicated by increased electrical conductivity and water temperature in streams with more agriculture areas. In conclusion, the conservation of the native forest vegetation is essential to maintain habitat characteristics and ecological processes in streams and to avoid the loss of specialist species in fish communities.
