... the wet season, temperatures vary from 11.9°C to 19.1°C with an average rainfall of 201 mm to 481 mm per month (June to November) (Prediction of Worldwide Energy Resources 2022). All reported organisms were found active at night during the dry season (Table 1). The sex and age were determined according to size and presence or absence of mental glands (Petranka 1998). ...Context 2
... observed more salamanders near the water on the driest nights (high values of VPD). Despite the high values of VPD, resistance to dehydration of this species may increase in high-temperature conditions (Table 1), which has been observed in other species of plethodontids ( Riddell and Sears 2015). (3) Although this species has been associated with bromeliads (McEntire 2016, Parra-Olea et al. 2020, we found all individuals on top of leaves, branches, or trunks not higher than 0.76 m above the ground. ...Context 3
... one individual (Id2) was away from water. However, this site had the highest percentage of humidity, the lowest temperature, and the lowest VPD values in relation to the sites where the other five individuals were found close to water (Table 1). These observations suggest that periods of activity of this species seem to correlate with low-temperature nights, when they are active for some hours before retreating to their shelters in the canopy and bromeliads to escape adverse conditions during the day (Ruano-Fajardo et al. 2014, Riddell and Sears 2015, McEntire 2016. ...Context 4

Megalobatrachonema nipponicum Yamaguti, 1941 (Nematoda: Cosmocercoidea: Kathlaniidae), the type species of the genus Megalobatrachonema, had been only once reported from the Japanese giant salamander, Andrias japonicus (Temminck, 1836) (Amphibia: Cryptobranchidae), in the last 80 years. Herein, we reported the present species from A. japonicus and...
