Abstract

We conducted standardized visual searches at night for brown treesnakes (Boiga irregularis) and geckos, where we alternated between spotlight and floodlight lamps. Floodlights rendered us 25% more snakes and 71% more geckos than did spotlights. We show data on searcher variability and discuss what might affect the relative benefit of different lamp types. ?? 2009 Brill Academic Publishers.

Low thermal tolerances of stream amphibians in the Pacific Northwest: Implications for riparian and forest management

Temperature has a profound effect on survival and ecology of amphibians. In the Pacific Northwest, timber harvest is known to increase peak stream temperatures to 24??C or higher, which has potential to negatively impact cold-water stream amphibians. I determined the Critical Thermal Maxima (CT max) for two salamanders that are endemic to the Pacific Northwest. Rhyacotriton variegatus larvae acclimated at 10??C had mean CTmax of 26.7 ?? 0.7 SD??C and adults acclimated at 11??C had mean CT max of 27.9 ?? 1.1??C. These were among the lowest known values for any amphibian. Values were significantly higher for larval Dicamptodon tenebrosus acclimated at 14??C (x = 29.1 ?? 0.2??C). Although the smallest R. variegatus had some of the lowest values, size of larvae and adults did not influence CTmax in this species. Current forest practices retain riparian buffers along larger fish-bearing streams; however, such buffers along smaller headwaters and non-fish bearing streams may provide favorable habitat conditions for coldwater-associated species in the Pacific Northwest. The current study lends further evidence to the need for protection of Northwest stream amphibians from environmental perturbations. Forest guidelines that include riparian buffer zones and configurations of upland stands should be developed, while monitoring amphibian responses to determine their success. ?? 2008 Brill Academic Publishers.

Brown treesnake (Boiga irregularis) trappability: Attributes of the snake, environment and trap

We examined three classes of factors that may influence brown treesnake (Boiga irregularis) trappability on Guam: (1) attributes of the snake, (2) attributes of the environment and (3) attributes of the trap. The attributes of the snake we considered included body condition, length and sex. Heavier snakes for a given size (better body condition) moved less and were less easily trapped. Longer snakes were easier to trap. Males were also slightly more easily trapped than females. We compared brown treesnake trappability between two study sites that differed greatly in the abundance of diurnal skinks, an important prey item for smaller snakes. We predicted that snakes, especially small individuals (<800 mm snout-vent length), would be more easily trapped in the low prey environment, a result that received only weak support from our data. However, small snakes were rarely trapped under any circumstance. We also predicted that diurnal foraging would be observed in the site with a higher density of diurnal prey, but daytime snake captures were negligible at both sites. Two attributes of traps that we varied were attractant (mouse vs. skink) and entrance flaps (present vs. absent). Traps with mice as attractant registered 6-16 fold more snake captures. We found little influence of entrances on captures. These modulators of brown treesnake trappability may have analogues in a variety of species, especially species that undergo an ontogenetic shift in diet. ?? 2008 Brill Academic Publishers.

Prevalence of the amphibian pathogen Batrachochytrium dendrobatidis in stream and wetland amphibians in Maryland, USA

The amphibian chytrid fungus Batrachochytrium dendrobatidis , responsible for the potentially fatal amphibian disease chytridiomycosis, is known to occur in a large and ever increasing number of amphibian populations around the world. However, sampling has been biased towards stream- and wetland-breeding anurans, with little attention paid to stream-associated salamanders. We sampled three frog and three salamander species in the Chesapeake and Ohio Canal National Historic Park, Maryland, by swabbing animals for PCR analysis to detect DNA of B. dendrobatidis . Using PCR, we detected B. dendrobatidis DNA in both stream and wetland amphibians, and report here the first occurrence of the pathogen in two species of stream-associated salamanders. Future research should focus on mechanisms within habitats that may affect persistence and dissemination of B. dendrobatidis among stream-associated salamanders
