Ecological correlates of extinction risk and persistence of direct-developing stream-dwelling frogs in Mesoamerica

Recent Herpetological Records of Seldom-Observed Species From the Cordillera De Talamanca, Costa Rica

“…Epizootics linked to Bd peaked during the 1980s and 1990s (e.g., Whitfield et al, 2016). Currently, Bd occurs widely throughout the country in an endemic state that continues to pose risk to amphibians (Zumbado-Ulate et al, 2019, 2022. However, various dramatically-declined species have recently shown signs of recovery, while previously 'lost' amphibian taxa are being rediscovered (Abarca et al, 2010;González-Maya et al, 2013;Chaves et al, 2014;Jimenez & Alvarado 2017;Zumbado-Ulate et al, 2019, 2022.…”

While some of these findings may indeed reflect shifts in disease dynamics, it is important to consider that these records may also represent observations of rarely recorded species, and are now only being recorded due to an increase in survey efforts, including expeditions to previously unexplored areas (e.g., Boza-Oviedo et al, 2012;Salazar-Zuniga et al, 2019).…”

Cave-Dwelling Populations of the Monstrous Rainfrog (Craugastor pelorus) from Mexico

“…Despite a rich bat community [19], its amphibiofauna has been largely understudied [20]. Here, we report on two populations Craugastor pelorus is a direct-developing stream-dwelling anuran with a patchy distribution limited to the Chiapas and Tabasco states of Mexico [21][22][23][24][25][26]. The species is strongly associated with streams from the upper tributaries that flow into the Grijalva and Usumacinta rivers [10,16], and are often limited to premontane and lower montane wet forests [23][24][25].…”
