The phylogenetic distribution and morphological variation of the 'pouch' in female snakes
TLDR
A broad sampling of femalesnakes revealed that the pouch evolved once on the branch leading to Colubro-ides, and variation in pouch mor-phology observed does not appear to be correlated with the evolutionary history of ColUBroides and polymorphism within families is common.

A FORTY-THREE YEAR MUSEUM STUDY OF NORTHERN CRICKET FROG (ACRIS CREPITANS) ABNORMALITIES IN ARKANSAS: UPWARD TRENDS AND DISTRIBUTIONS
TLDR
Proposed hypotheses for distributions include: 1) A. crepitans might possess naturally high abnormality levels, and land use practices of the Delta may reduce this variability; 2) an unknown xenobiotic may be in Ozark streams causing increased numbers of abnormalities; 3) the museum's collection effort may be skewed; 4) Delta habitat might be more favorable for green tree frogs (Hyla cinerea) allowing this species to drive out A.crepitans through competition.

Status of the Ozark Hellbender, Cryptobranchus Bishopi (Urodela: Cryptobranchidae), in the Spring River, Fulton County, Arkansas
We conducted a tag and release study of the Ozark hellbender along a 26 km stretch of the Spring River from mid-July through mid-November, 1991, to determine current population levels. Salamanders…
Predicted climate change may spark box turtle declines
TLDR
This work modeled the growth response of Three-toed Box Turtles (Terrapene carolina triunguis) to fluctuations in ambient temperature and precipitation and predicted that there is less than 20% possibility of hatchling turtles growing during their first year.
