Symbiotic bacteria often help their hosts acquire nutrients from their diet, showing trends of
co‐evolution and independent acquisition by hosts from the same trophic levels. While these …

LEATHERBACKS (Dermochelys coriacea) are among the largest living reptiles (>900 kg) 1,
2 and range from the tropics to north of the Arctic Circle 3, 4 . They maintain elevated body …

Peroxynitrite, a cytotoxic oxidant formed from nitric oxide (NO) and superoxide, induces
DNA strand breakage, which activates the nuclear enzyme poly(ADP-ribose) synthase (PARS; …

What makes synthetic aperture radar (SAR) automatic target recognition (ATR) hard? This
question is explored by reviewing target, environment, and sensor variability and how they …

Life histories evolve as a response to multiple agents of selection, such as age‐specific
mortality, resource availability or environmental fluctuations. Predators can affect life‐history …

A P-glycoprotein (P-gp) IC 50 working group was established with 23 participating
pharmaceutical and contract research laboratories and one academic institution to assess …

The microbiome can significantly impact host phenotypes and serve as an additional source
of heritable genetic variation. While patterns across eukaryotes are consistent with a role for …

We monitored meteorological variables, daily and seasonal patterns of body temperature,
corresponding operative temperatures, and microhabitat utilization by desert tortoises (…

The biology of sea turtles is intimately tied to the thermal constraints of their environment. From
the time a hatchling enters the water, a sea turtle lives in an environment that is thermally …

Power scaling relationships between body mass and organismal traits are fundamental to
biology. Compilations of mammalian masses and basal metabolic rates date back over a …
