lizards, etc ; Brachylophus; Circus; mammals; predation; swamps; Fiji; Show all 7 Subjects
Abstract:
... The Fijian crested iguana (Brachylophus vitiensis) is the largest extant lizard in Fiji, where it enjoys life in the absence of any mammalian predators. On the only island where this iguana is abundant, the only predator appears to be the swamp harrier (Circus approximans), which is non‐selective in its iguana prey, catching individuals in a similar proportion to their size availability. Here we r ...

Abstract:
... Malformations of vertebrae potentially occur across many taxa, particularly in Testudines, which are susceptible to kyphosis (dorsoventral curvature of the spine). Such malformations may stem from either genetic or environmental origins, and their prevalence and associated impacts on survival remain poorly understood. However, scoliosis (sideways curvature of the spine) is rarely reported and espe ...

Abstract:
... Archaeologists relate increasing forager reliance on small animals and broad-spectrum resource use to environmental and demographic changes in temperate regions during Marine Isotope Stage (MIS) 2, 29-14.7 thousand years ago (ka), and MIS 1, after 14.7 ka. However, little research has examined the factors that influenced small game hunting in the arid and semi-arid tropics of eastern Africa during ...

Abstract:
... Diet of Quedenfeldtia moerens was studied from March 2018 to April 2019, in the Arid Anti-Atlas Mountain in Morocco. This study was carried by a repetitive sampling of available prey in the field using pitfall traps and prey consumed by 130 lizards from fecal pellets. Analysis shows that lizard's diet was composed exclusively of arthropods with four major taxonomic groups: Formicidae, Coleoptera, ...
lizards, etc ; community structure; forests; habitats; savannas; species richness; Benin; Show all 7 Subjects
Abstract:
... Studies of animal communities along habitat gradients are useful in understanding the ecologicsl factors affecting species diversity and richness. Almost no investigations have been carried out on the community structure of vertebrate groups along habitat gradients modified by humans in historical or prehistoric times. Here, we analyze the community structures of lizards in suburban Lomé (Togo) an ...
lizards, etc ; Diporiphora; ecology; mating behavior; tail; zoology; Western Australia; Show all 7 Subjects
Abstract:
... Communication signals underpin the social lives of animals, from species recognition to mate selection and territory defense. Animal signals are diverse in structure between and within species, with the diversity reflecting interacting factors of shared evolutionary history, constraints imposed on senders and receivers and the ecological context in which signalling takes place. The dragon lizards ...

lizards, etc ; Cordylidae; biodiversity; ectothermy; integument; melanin; melanosis; models; reflectance; viability; Show all 10 Subjects
Abstract:
... The impact of climate change on global biodiversity is firmly established, but the differential effect of climate change on populations within the same species is rarely considered. In ectotherms, melanism (i.e. darker integument due to heavier deposition of melanin) can significantly influence thermoregulation, as dark individuals generally heat more and faster than bright ones. Therefore, darker ...
lizards, etc ; Neotropics; Sceloporus; cats; color; fauna; predation; risk; wildlife; Mexico; Show all 10 Subjects
Abstract:
... Domestic cats are a potential risk for native fauna in the Neotropics. Intrinsic (age, weight, sex, color) and extrinsic (nocturnal confinement, time spent outside the home, distance to green areas, etc.) factors can influence the type and quantity of prey that cats take to their homes. The study goal was to evaluate domestic cat predation in a Neotropical city. We intend to answer the following q ...
lizards, etc ; Podarcis; biochemistry; cameras; case studies; hardness; kinematics; physiology; tongue; Show all 9 Subjects
Abstract:
... The kinematics of lizard feeding are the result of complex interactions between the craniocervical, the hyolingual, and the locomotor systems. The coordinated movement of these elements is driven by sensory feedback from the tongue and jaws during intraoral transport. The kinematics of jaw movements have been suggested to be correlated with the functional characteristics of the prey consumed, such ...

Abstract:
... Understanding high biodiverse areas and interactions among organisms requires reciprocal action between scientists and community through citizen science. This paper results from the joint efforts of an amateur nature photographer and scientists to describe the predation behaviour of the heron Ardea cocoi upon the lizard Ameiva ameiva. We also discuss the importance of citizen science and digital p ...

Abstract:
... Warming temperatures caused by climate change are predicted to vary temporally and spatially. For mid‐ and high‐latitude reptiles, the seasonal variation in warming temperatures experienced by embryos and hatchlings may determine offspring fitness, yet this has remained largely unexplored. To evaluate the independent and interactive influence of seasonal variation in warming temperatures on embryo ...

Abstract:
... In 1859, Charles Darwin proposed that species are not fundamentally different from subspecies or the varieties from which they evolve. A century later, Dobzhansky (1958) suggested that many such lineages are ephemeral and are likely to reverse differentiation through introgression (Figure 1a); only a few evolve complete reproductive isolation and persist in sympatry. In this issue of Molecular Eco ...

Abstract:
... Insectivorous lizards can alter arthropod community structure and composition. Collared lizards (Crotaphytus collaris) are believed to be keystone predators for Ozark glade grasshopper (Orthoptera) communities by increasing species richness on smaller glades. However, the interaction between collared lizard presence and glade area on orthopteran species richness has been inconsistent between studi ...
... Animals signals must be detected by receiver sensory systems, and overcome a variety of local ecological factors that could otherwise affect their transmission and reception. Habitat structure, competition, avoidance of unintended receivers and varying environmental conditions have all been shown to influence how animals signal. Environmental noise is also crucial, and animals modify their behavio ...

Abstract:
... AIM: Our understanding of species’ responses to climate depends on choosing the scale for the analysis. Processes driving physiological adaptation that occur at the small spatial scales most relevant to animals may be masked in correlations between organismal traits and broad‐scale climatologies, but the extent to which this undermines our understanding of the macroevolution of physiological trait ...
... Physiology is crucial for the survival of invasive species in new environments. Yet, new climatic conditions and the limited genetic variation found within many invasive populations may influence physiological responses to new environmental conditions. Here, we studied the case of the delicate skinks (Lampropholis delicata) invading Lord Howe Island (LHI), Australia. On LHI, the climate is differe ...
... In parasite–host interactions host species may differ in their ability to fight parasitic infections, while other ecological interactions, including competition, may differentially alter their physiological state, making them even more susceptible to parasites. In this study, we analyse the haemogregarine blood parasites infecting two competing lizard species, Iberolacerta horvathi and Podarcis mu ...
... Bite force can be an important aspect of a lizard’s organismal performance, and is likely to be subject to influence by ambient conditions including an individual’s thermal environment. We examined the effects of body temperature (Tb) on initial bite force of rock- and crevice-dwelling individuals of three species of lizards: Abronia graminea (Anguidae), Barisia imbricata (Anguidae), and Xenosauru ...
