“…The environmental filtering by the dry phase favours species that have developed specific life history adaptations, such as annualism (Nielsen, Hillman, Smith, & Shiel, 2002; Ruetz, Trexler, Jordan, Loftus, & Perry, 2005; Wellborn, Skelly, & Werner, 1996), as with the annual fish of the family Rivulidae (Costa, 2002). Annual fish are unique in their ability to survive in temporary wetlands; they have short, seasonal life cycles, laying eggs that lie dormant in the soil (diapause stages) once the pools have evaporated and then resume development and hatch when the water returns (Costa, 2002, Berois, Arezo, Papa & Chalar, 2015, Volcan & Lanés, 2018). Often several annual fish species coexist in a single wetland, despite the small size and low complexity of the ephemeral environments, suggesting elaborate ecological relationships between species to avoid competition (Costa, 2009; Volcan, Gonçalves, & Guadagnin, 2019).…”

• The fish community of temporary wetlands is highly dynamic due to the marked seasonal changes in hydrological and limnological conditions. In this study, we evaluated spatiotemporal variation in the fish community and the influence of environmental factors on this variation in temporary wetlands in southern Brazil.

“…As many species of the family Rivulidae, A. queguay presents an annual life cycle which includes drought resistant eggs and diapausing embryos. All species of Austrolebias are obligate annuals (Berois et al 2016). In the Pampa biome there is not a defined dry season, so dried environments can be found between mid spring to early fall (depending on the year), when evaporation is higher than precipitations (Williams 2006;García et al 2017).…”

In this article we describe a new species of the annual fish genusAustrolebiasfrom the lower Uruguay river basin. The fusion of the urogenital papilla to the first anal fin ray in males and the pigmentation pattern, indicates a close relationship with the clade formed byA.bellottii,A.melanoorus, andA.univentripinnis. The new species can be differentiated from those by the following combination of characters: presence of well-defined light bands contrasting with the sides of the body, the distal portion of the anal fin dark gray, pelvic fins dark bluish green and bases united at about 50–80% on their medial margins, pectoral fins with iridescent blue sub-marginal band, and general coloration of body bluish green. The new species can only be found in wetlands of the Queguay river, an area included in the Uruguayan protected areas system and represents so far the only annual fish species endemic to the lower Uruguay river basin.

“…Among the freshwater fishes better adapted to the extreme hydrological regime of the semiarid regions are the seasonal killifishes of the Rivulidae family. These species live in seasonal ponds filled by rain that dry in a part of the year, when the eggs deposited on the substrate survive due to developmental and metabolic diapauses (Murphy and Collier 1997;Berois et al 2016). In the semiarid Caatinga, composed of four freshwater ecoregions, the genera Cynolebias Steindachner, 1876 and Hypsolebias Costa, 2006 are represented by 20 and 35 valid species, respectively, with highest richness in the São Francisco ecoregion (Lima et al 2017;Costa 2017;Costa et al 2018a, b, c).…”

The Rivulidae fish family, which includes Neotropical seasonal killifishes, is one of the most diverse taxonomic groups in the aquatic systems of Caatinga in Brazil. Cynolebias and Hypsolebias genera, with 20 and 35 endemic species, respectively, concentrate the greatest diversity of rivulid species in the semiarid. Sixty-eight years after the first records of annual killifishes in the Mid-Northeastern Caatinga ecoregion (MNCE), only four valid species have been sampled in this area. Here we combined bibliographic surveys and recent samplings to investigate the distribution of seasonal rivulids in MNCE. Twenty-one records were obtained, nine of which are new localities, expanding the distribution of three species: Hypsolebias martinsi, H. antenori and Cynolebias microphthalmus. Hypsolebias&nbsp;longignatus is still only known from its type locality in Ceará, near the Environmental Protection Area in Pacoti River, and has not been sampled ever since its description in 2008. Among the four species present in MNCE, H. antenori is the only species occurring within the limits of a conservation unit in the Furna Feia National Park. Anthropogenic impacts were observed in most temporary habitats visited, which ranged from river channel to small ponds in cave entrances. All records are found in coastal basins that discharge in the northern coast of the MNCE, in Ceará and Rio Grande do Norte states, which are crucial for the conservation of the Caatinga’s killifishes. The results also evidenced the importance of karstic habitats in the Jandaíra Formation as potential biotopes for seasonal fish in MNCE. This information must be used to update the conservation status of these species and highlight the importance of strategies for preserving the Caatinga’s temporary aquatic habitats, which should be considered for environmental licensing purposes.
