Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Life, but Not as We Know It: Why Fine‐Tuning Arguments Fail
ABSTRACT Definitions of “life” and theories of life are systematically neglected in arguments for and from fine‐tuning. Despite claims to be neutral about the definition of “life,” fine‐tuning arguments generally presuppose that life requires a form of structural complexity only afforded by physicochemical complexity of the sort with which we are ...

Postembryonic development of the predatory strike mechanics in a praying mantis (Insecta: Mantodea)
Praying mantis forelegs capture prey using specific kinematic and kinetic traits that change in size and morphology during postembryonic growth and sexual dimorphism influences these dynamics. Strike forces grow hyperallometrically with body weight; larger mantises show longer strike durations, slower joint angular velocities and increased tibia ...

Abstract Introduction Desert fishes are vulnerable to anthropogenic environmental alterations that degrade habitat and reduce water availability, but these same fishes benefit from restoration actions that reverse the causes of decline. Ash Meadows speckled dace (Rhinichthys osculus nevadensis) is a federally endangered minnow endemic to the Mojave ...

Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...
