reptiles--lizards and snakes--are among the most diverse groups of vertebrates, with more than 9,000 living species.
Thermal performance of squamate
embryos with respect to climate, adult life history, and phylogeny.
The outer, beta keratin-rich layer of the squamate
epidermis bears intricate fine sculpturing (microornamentation), which varies from base to apex of an individual scale.
In addition to well-preserved macroscopic vertebrate remains, the dermoskeleton microremains of a number of squamate
early vertebrate species are extremely abundant in Ohesaare and form bone beds in several levels of the section (Nestor 1990; Marss & Nestor 2014).
Evolutionary diversification of clades of squamate
The phylogeny of Squamate
reptiles (Lizards, Snakes, and Amphisbaenians) inferred from nine nuclear protein-coding genes.
Cutaneous mycobiota of captive squamate
reptiles with notes on the scarcity of Chrysosporium anamorph Nannizziopsis vriesii.
Problems on the level of not showing Saffron-crested Tyrant-Manakin (Neopelma chrysocephalum) in northern Peru; of showing Long-winged Antwren (Myrmotherula longipennis) extensively between the Rio Napo in Peru and the Negro in Brazil where it is largely or completely absent; of missing the interface between Squamate
Antbird (Myrmeciza squamosa, shown extensively north into Rio de Janeiro) and White-bibbed Antbird (M.
In this last exercise, the "descent with modification" schema is transferred from squamate
reptiles to all organisms.
The distribution of scales in these squamate
species varies widely, but at least some are always present between the veins on the abaxial side of the blade (Kessler and Smith, 2005).
Therefore, thermoregulation might be the most important factor in determining squamate
habitat use patterns (Grant 1990, Peterson et al.
More generally, much of the interspecific variation in thermoregulatory tactics among squamate
reptiles may reflect differences in species-specific costs and benefits of thermoregulation rather than variation among habitats.
