  1. Lag of Immunity Across Seasonal Acclimation States in Gopher Tortoises (Gopherus Polyphemus)

    We examined the role that rapid temperature change has on Gopherus polyphemus immunity and found that rapid temperature reductions during summer significantly negatively affect immunity. However, rapid temperature increases during winter provide no measurable immunological benefit.

  2. Arboreal locomotion in Eurasian harvest mice Micromys Minutus (Rodentia: Muridae): The gaits of small mammals

    Our findings in Micromys minutus suggest that gait metrics do not greatly differ between larger and smaller arboreal mammals, except for how velocity is regulated. Furthermore, they also show that diagonal sequence gaits are not necessary for terminal branch quadrupedalism at a small body size.

  3. Insect Immunity Varies Idiosyncratically During Overwintering

    We compared immune responses during overwintering in three insect species. Immunity varies seasonally in a species-dependent fashion. Warmer and less thermally variable microhabitats decrease spring immune activity. Species-specific responses are likely a product of the response to different iterations of multiple overwintering stressors.

  4. Temperature Preference and Sex Differentiation in African Catfish, Clarias gariepinus

    • (1)
      African catfish larvae moved spontaneously through a thermal continuum from lower (28°C) to higher (32 and 36.5°C) temperatures during the sex differentiation period.
    • (2)
      Thermal preference is highly variable and differed according to progeny and early life periods (before, during, and after high thermosensitive period).
    • (3)
      Displacements in a thermal continuum system resulted in masculinization in all tested progenies.
  5. Size-Dependent Consequences of Exogenous Cortisol Manipulation on Overwinter Survival and Condition of Largemouth Bass

    We found no evidence of a size-dependent response to stress in a wild teleost fish, but some evidence for sex-specific changes in condition and health metrics.
