Evolution of the eyes of vipers with and without infrared-sensing pit organs [PDF]

, 2019
We examined lens and brille transmittance, photoreceptors, visual pigments, and visual opsin gene sequences of viperid snakes with and without infrared-sensing pit organs. Ocular media transmittance is high in both groups.

A century of theories of balancing selection

Biological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

Perspectives on the Effect of Incubation Temperature on Pine Snake Hatchlings

Ethology, EarlyView.
Effect of timing of egg‐laying and incubation temperature on the possible phenology of events for early egg‐laying females (laying June 15, the earliest laying date), the mid‐laying date (July 4), and late egg‐laying females (July 17, the latest egg‐laying date). Based on data from many papers.

Eliciting a predatory response in the eastern corn snake (Pantherophis guttatus) using live and inanimate sensory stimuli: implications for managing invasive populations [PDF]

, 2014
North America's Eastern corn snake (Pantherophis guttatus) has been introduced to several islands throughout the Caribbean and Australasia where it poses a significant threat to native wildlife. Invasive snake control programs often involve trapping with

Morphological traits and environmental preferences of the Blunt‐headed tree snake Imantodes cenchoa: the effects of sex and ontogeny

Journal of Zoology, EarlyView.
Understanding how animals interact with their environment across life stages is key for conservation. In our long‐term study of the Blunt‐headed tree snake (Imantodes cenchoa) in the tropical rainforest of Los Tuxtlas, Mexico, we tracked over 240 individuals and found age‐related differences in environmental preferences.
