Testing for personality consistency across naturally occurring behavioral contexts in sanctuary chimpanzees (Pan troglodytes)

open access: yesAmerican Journal of Primatology, Volume 85, Issue 1, January 2023., 2023
Sanctuary chimpanzees show consistency of their personality‐based behaviors across real‐life contexts and over time while displaying interindividual differences in the consistency of their personality‐based behavioral profile Abstract Personality is both a reflection of the bio‐behavioral profile of individuals and a summary of how they typically ...

Lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene of Mazaterón (Soria, Spain)

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The assemblage of lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene locality of Mazaterón (Spain) is described. Considering the rather limited material available for the study, the assemblage shows a moderate diversity with eight taxa corresponding to five different families.

The elusive scleral cartilages: Comparative anatomy and development in teleosts and avians

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The sclera of all vertebrate eyes is comprised of connective tissue, with some organisms developing cartilage within this tissue. A review of the cartilages that have been described in the vertebrate sclera and their anatomical relationships is discussed together with their potential homology.

A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes

open access: yesBMC Evolutionary Biology, 2013
BackgroundThe extant squamates (>9400 known species of lizards and snakes) are one of the most diverse and conspicuous radiations of terrestrial vertebrates, but no studies have attempted to reconstruct a phylogeny for the group with large-scale taxon ...

Large-scale molecular phylogeny, morphology, divergence-time estimation, and the fossil record of advanced caenophidian snakes (Squamata: Serpentes)

open access: yesPLoS ONE, 2019
Caenophidian snakes include the file snake genus Acrochordus and advanced colubroidean snakes that radiated mainly during the Neogene. Although caenophidian snakes are a well-supported clade, their inferred affinities, based either on molecular or ...

Addressing Wallacean shortfall using small sampling approach: a case study with endemic Lycodon flavicollis (Squamata: Colubridae) Mukherjee & Bhupathy, 2007

open access: yesJournal of Asia-Pacific Biodiversity, 2021
Delineating species distribution comprising information on habitat suitability is vital for developing conservation strategies. Like many other snake species, Lycodon flavicollis is a poorly studied peninsular Indian endemic species known only from few ...

Ovidian Linearities

open access: yesDictynna, 2022
This paper considers some implications of Ovid’s concept of a perpetuum carmen by examining how the ‘narrative line’ of the poem takes shape. I focus on how the Metamorphoses can be described in terms of horizontality, or verticality, or both, and use ...

Optimal Axes of Siberian Snakes for Polarized Proton Acceleration [PDF]

open access: yesPhys.Rev.STAccel.Beams7:121001,2004, 2004
Accelerating polarized proton beams and storing them for many turns can lead to a loss of polarization when accelerating through energies where a spin rotation frequency is in resonance with orbit oscillation frequencies. First-order resonance effects can be avoided by installing Siberian Snakes in the ring, devices which rotate the spin by 180 degrees

Beyond the ‘big four’: Venom profiling of the medically important yet neglected Indian snakes reveals disturbing antivenom deficiencies

open access: yesPLoS Neglected Tropical Diseases, 2019
Background Snakebite in India causes the highest annual rates of death (46,000) and disability (140,000) than any other country. Antivenom is the mainstay treatment of snakebite, whose manufacturing protocols, in essence, have remained unchanged for over

A Species-Level Phylogeny of Extant Snakes with Description of a New Colubrid Subfamily and Genus

open access: yesPLoS ONE, 2016
Background With over 3,500 species encompassing a diverse range of morphologies and ecologies, snakes make up 36% of squamate diversity. Despite several attempts at estimating higher-level snake relationships and numerous assessments of generic- or ...
