Estimating the geographic range of a threatened shark in a data-poor region: Cetorhinus maximus in the South Atlantic Ocean
(Oxford University Press, 2015-10)
The distribution of the planktivorous basking shark Cetorhinus maximus is influenced by zooplankton abundance at small scales and temperature at medium scales in the North Atlantic. Here, we estimate the distribution of ...
Basking and retreat site selection of phymaturus palluma, a rock-dwelling lizard in the highlands of aconcagua
(Academia Brasileira de Ciencias, 2021-05)
Basking and retreat sites constitute a key resource in the habitat of any ectotherm. Identifying the elements that are used and modelling the microhabitat selection of species is crucial for assessing the impact of ...
A hot knot of toads: Aggregation provides thermal benefits to metamorphic Andean toads
(Pergamon-Elsevier Science Ltd, 2008-02)
We tested the thermal benefits of aggregation ("knotting") for a high-elevation (>4300 m) population of metamorphic Rhinella spinulosa. Fewer knots were recorded when the sun was low on the horizon and aggregating toads ...
Activity Patterns and Thermoregulatory Behavior of the Viviparous Lizard Phymaturus palluma in Aconcagua Provincial Park, Argentine Andes
(Herpetological Conservation and Biology, 2019-08)
Temperature has a significant influence on physiology, ecology, and life history of ectotherms. Despite environmental fluctuations, lizards have developed behavioral mechanisms to maintain a relatively constant body ...
Resource segregation in two herbivorous species of mountain lizards from Argentina
(British Herpetological Society, 2014-10)
Lizard assemblages may experience resource partitioning in the spatial, trophic or temporal dimensions of their niche. Niche segregation does not always imply competition, and the role of interspecific competition is better ...
The turtle Trachemys scripta elegans (Testudines, Emydidae) as an invasive species in a polluted stream of southeastern Brazil
(British Herpetological Society, 2009-12)
The north American freshwater turtle Trachemys scripta elegans has been recently reported as an exotic species in several regions of the world. During an investigation on the ecology of the Chelid turtle Phrynops geoffroanus ...
The evolution of dermal shield vascularization in Testudinata and Pseudosuchia: phylogenetic constraints versus ecophysiological adaptations
(The Royal Society, 2020-01)
Studies on living turtles have demonstrated that shells are involved in the resistance to hypoxia during apnea via bone acidosis buffering; a process which is complemented with cutaneous respiration, transpharyngeal and ...
Borate Deposits of Turkey and Argentina: A Summary and Geological ComparisonTürkiye ve Arjantin Borat Yataklar›: Jeolojik Bir Karfl›laflt›rma
(Tübitak, 2000-12)
Turkey has the largest borate reserves in the world and Argentina is in third place. Both countries have calcium and sodium borate deposits where colemanite, ulexite and borax are the principal minerals. We present here a ...
