UPDATED GEOGRAPHIC DISTRIBUTIONS OF MICHIGAN HERPETOFAUNA:: A SYNTHESIS OF OLD AND NEW SOURCES [PDF]
, 2016 Recently a comprehensive overview of reptiles and amphibians in Michigan was published. Unfortunately, the distributions of the species represented were compiled before widespread accessibility to technological tools providing greater access to museum ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT The southern alligator lizard (Elgaria multicarinata) exhibits prolonged mate‐holding behavior. This behavior maybe be underpinned by a phenomenon known as sustained force, observed in the jaw muscles of this species, in which the muscle fails to relax between subsequent contractions.

Fish and amphibians as bat predators [PDF]
, 2015 Although bats (Chiroptera) belong to the most diverse mammalian orders, study of diversity of their natural predators has been seriously neglected for a long time.

Many roads to reservoirs? How susceptibility and shedding shape host competence in amphibians
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Host competence—the ability to acquire, harbour and transmit infections—drives pathogen spread and persistence in multi‐host communities. Evaluating species‐specific competence is critical for predicting transmission, particularly for generalist fungal pathogens like ...

Software and methods for oligonucleotide and cDNA array data analysis. [PDF]
, 2002 Two HTML-based programs were developed to analyze and filter gene-expression data: 'Bullfrog' for Affymetrix oligonucleotide arrays and 'Spot' for custom cDNA arrays. The programs provide intuitive data-filtering tools through an easy-to-use interface. A

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans
Integrative Zoology, EarlyView.Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

Synaptic up-scaling preserves motor circuit output after chronic, natural inactivity
eLife, 2017 Neural systems use homeostatic plasticity to maintain normal brain functions and to prevent abnormal activity. Surprisingly, homeostatic mechanisms that regulate circuit output have mainly been demonstrated during artificial and/or pathological ...

Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)
Journal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.
