Studies on crustacean communities in Chilean wetlands are scarce. The aim of this study was to characterize the crustacean community in forested wetlands from southern Chile and to establish their relation with the variations in the hydrological regime. In total, 540 samples were taken using three complementary sampling techniques in five wetlands during 2011 and 2012. The results show a total of four species of crustaceans, of which the amphipod Hyalella patagonica (Cunningham, 1871) (Hyalellidae) was dominant in ephemeral wetlands and the isopod Heterias exul (Mueller, 1892) (Janiridae) in permanent wetlands. The other species (the decapods Parastacus pugnax (Poeppig, 1835) (Parastacidae) and Aegla araucaniensis (Jara, 1980) (Aeglidae)) showed abundances below 6% in all wetlands. The identified crustaceans presented marked variations, both at a temporal scale and between wetlands with different hydrological regimes, both at the species level and at the crustacean community level. These patterns were mainly explained by changes registered in the annual hydroperiod and our results conform to the existing information that would indicate the importance of the inclusion of hydrological patterns in descriptions of freshwater communities.

Abstract While ephemeral wetlands contribute significantly to regional freshwater biodiversity, their role in supporting threatened and imperiled species of crayfish is not widely recognized. As the center of global crayfish biodiversity, the southeastern United States (US), and the state of Alabama (AL) in particular, are important focal areas where information is needed to develop understanding of habitat constraints determining the distributions of crayfish species. To this end, we documented crayfish species associated with ephemeral wetlands and associated wetland habitats that have been traditionally under sampled. Fifteen species of crayfish were documented among 96 survey sites. This assemblage included three Alabama state-listed Priority 1 species [Cambarellus diminutus Hobbs, Fallicambarus burrisi Fitzpatrick, Procambarus viaeviridis (Faxon)] and five Priority 2 species [Hobbseus prominens (Hobbs), Orconectes lancifer (Hagan), Procambarus evermanni (Faxon), P. leconti (Hagan), P. marthae Hobbs]. An undescribed species of Cambarellus (“sp. A”) was also documented, and will presumably be eventually designated a Priority 1 species in Alabama due to its restricted distribution and apparent endemism. Ten species of crayfish were documented from ephemeral wetlands, including four Priority 1 and 2 species [Cambarellus sp. A (presumed Priority 1 species), H. prominens, P. marthae, P. viaeviridis]. Most populations of Priority 1 and 2 species we documented are within the 100-year floodplain of the Black Warrior River. Ephemeral wetlands and associated wetland habitats within the floodplains of large rivers thus appear to be vital habitat for threatened and imperiled crayfish in Alabama. Our results suggest that future crayfish surveys should include sampling of these important but often overlooked habitats.

Calling Activity

Drivers of anuran reproductive activity may include multiple and independent environmental variables. To determine the relative influence of season, temperature, and precipitation in initiating frog reproduction, we monitored a species-rich frog assemblage in south-central Alabama for 3 years and modeled calling activity of vocalizing males, who call to attract mates. We evaluated multiple hypotheses potentially explaining calling activity and we were able to identify significant influences of calling activity for all 11 anuran species considered in the analysis. Eight species were significantly influenced by month of survey and four of these were influenced by at least one additional environmental variable. In our study, precipitation was relatively unimportant in influencing calling activity, likely because breeding pools at the site are semipermanent and the species we sampled are not generally reliant on ephemeral wetlands. In general, our data suggest that different species within the same wetlands respond to different cues when initiating reproduction and calling activity is largely based on a combination of both environmental conditions and either seasonal changes or endogenous drivers.
