Island‐restricted reptiles are more threatened but less studied than their mainland counterparts
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

The Asian swamp eel and bullseye snakehead are two invasive organisms in Florida of ecological concern. In this study, a multiplex digital polymerase chain reaction (dPCR) assay is developed, optimized, and validated on water samples for environmental DNA (eDNA) analysis and monitoring. ABSTRACT Invasive species are a significant threat to a variety of

Quantification of intraskeletal histovariability in Alligator mississippiensis and implications for vertebrate osteohistology [PDF]
Bone microanalyses of extant vertebrates provide a necessary framework from which to form hypotheses regarding the growth and skeletochronology of extinct taxa.

The spectacled caiman (Caiman crocodilus) is a crocodylian native to Central and South America that has been introduced and established (reproducing in the wild) in several insular (i.e., Cuba, Puerto Rico, San Andres) and continental (i.e., Florida ...

ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...

A Taxa de conversão do alimento (FCR) do Caiman latirostris é mais eficiente a temperaturas mais elevadas [PDF]
The effects of temperature on the growth of Caiman latirostris were investigated in order to evaluate the efficiency of food conversion at 29 and 33°C. Sixty-eight captive raised animals, two months old, taken from four nests, were used.

IgH loci of American alligator and saltwater crocodile shed light on IgA evolution
Immunoglobulin loci of two representatives of the order Crocodylia were studied from full genome sequences. Both Alligator mississippiensis and Crocodylus porosus have 13 genes for the heavy chain constant regions of immunoglobulins. The IGHC locus contains genes encoding four immunoglobulins M (IgM), one immunoglobulin D (IgD), three immunoglobulins A

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny
Extant crocodylians may be divided into five clusters based on the residuals of four linear dental measurements (y‐axes) and their variation along the jaw (x‐axes). These clusters correlate to snout shape, prey preference, and feeding ecology, particularly prey size and the degree of processing necessary. Multiple families and subfamilies were found in

Rhabdomyosarcoma in a Texas Gopher Tortoise (Gopherus berlandieri). Case Report
Rhabdomyosarcomas are rarely reported in reptiles, and this is, to the authors′ knowledge, the second one described in a tortoise. A male captive terrestrial tortoise of at least 11 years of age (Gopherus berlandieri) was presented with a reddened growth of the distal aspect of the right posterior limb, measuring approximately 4.5 cm. The affected limb

Behavioural postures and the rate of body temperature change in wild freshwater crocodiles, Crocodylus johnstoni [PDF]
I recorded body temperature and behaviour of eight Crocodylus johnstoni in the wild over a 2-yr period in order to quantify the effect of posturing on body temperature and to provide a mechanistic explanation of how behaviour affects body temperature ...
