Homing and egg discrimination in the Western Slimy Salamander, Plethodon albagula (Caudata: Plethodontidae)

This study tests homing ability and egg discrimination in western slimy salamanders, finding that females return to their nests and discriminate between their own and unfamiliar eggs.

Using fuzzy sets to deal with uncertainty in single-species, single-season occupancy models.

This paper introduces fuzzy sets to improve occupancy modeling by handling uncertainty in detectability and presence-absence data, resulting in more robust and informative estimates.

Angular Substrate Preference and Molting Behavior of the Giant River Prawn, Macrobrachium rosenbergii, and its Implications for Cannibalism Management

The paper studies substrate preference and molting behavior in Giant River Prawns to improve cannibalism management in commercial settings.

Occurence of lymphedema in wild-caught anurans

The paper reports the occurrence of lymphedema in six wild-caught anuran species, noting specific species with confirmed records.

Diurnal Chorusing in Nine Species of North American Frogs

The paper surveys diurnal frog calling behavior in Louisiana and finds 60% of species participate in daytime breeding choruses, with four new species reports for this behavior.

Mass Mortality of Wood Frogs (Rana sylvatica) in the Ozark National Forest: Is it Acid Rain?

The paper reports a mass mortality event of wood frogs and other amphibians in the Ozark National Forest without identifying a definitive cause.

Life history trade-offs in ectotherms impart a pseudo-hormetic response, not hormesis.

The paper shows that ectotherms exhibit increased growth under immunological stress due to higher food intake, not improved physiological efficiency, suggesting a pseudo-hormetic response.
