From transporter to motor: Evolutionary and structural insights into the emergence of prestin's area‐motor activity in mammals

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Prestin, a member of the SLC26A family, is essential for the electromotility of mammalian outer hair cells, converting voltage changes into mechanical work. In contrast, nonmammalian orthologues function as anion transporters. To investigate the molecular and structural basis of this functional divergence, we performed ancestral sequence ...

Turtles as models for the maternal transfer of organic pollutants across reptile species, chemicals, and matrices

Ecotoxicology and Environmental Safety
Maternal offloading of chemicals presents a first exposure for embryos during a critical window of sensitive early life development. We aimed to develop reptile-specific models to quantify this offloading.

Inferred presence of extraoral tissues in Triassic archosauromorphs and the evolutionary implications for the clade Sauropsida

Palaeontology, Volume 69, Issue 3, 2026.
Abstract Recent work has suggested that the presence of extraoral soft tissues (‘lips’), in the form of labial scales in theropod dinosaurs, could be inferred based on: anteroposteriorly distributed foramina in the rostral bones, similar to extant lepidosaurs; vertically projected teeth; uniform enamel thickness in maxillary teeth; and an allometric ...

The invasive spectacled caiman (Caiman crocodilus) in Florida, United States: invasion timeline, insights, and implications for Everglades restoration

Frontiers in Amphibian and Reptile Science
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 ...

Detection of Antibodies to a Pathogenic Mycoplasma in American Alligators (Alligator mississippiensis), Broad-Nosed Caimans (Caiman latirostris), and Siamese Crocodiles (Crocodylus siamensis) [PDF]

Journal of Clinical Microbiology, 2001
ABSTRACTAn epidemic of pneumonia with fibrinous polyserositis and multifocal arthritis emerged in captive American alligators (Alligator mississippiensis) in Florida, United States, in 1995.Mycoplasma alligatorissp. nov. was cultured from multiple organs, peripheral blood, synovial fluid, and cerebrospinal fluid of affected alligators.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

The Bulletin of the Ecological Society of America, Volume 107, Issue 2, April 2026.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
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 ...

Development of a Duplex Digital PCR and Validation on eDNA Water Samples for Monitoring of the Asian Swamp Eel (Monopterus albus/Javanensis) and Bullseye Snakehead (Channa aurolineata/Marulius) in Florida, USA, Freshwater Ecosystems

Ecology and Evolution, Volume 16, Issue 2, February 2026.
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

Can alligators and crocodiles climb trees? This is the truth!

, 2023
Can alligators and crocodiles climb trees? Yes, alligators and crocodiles are capable of climbing trees. While it was once believed that these animals were unable to climb trees, scientific studies and observational evidence have since proven otherwise.
