ABSTRACT: Our earlier investigation of body temperature in the dwarf caiman Paleosuchus palpebrosus has shown that this species is a thermoconformer and that this behaviour is associated with habitat niche-specific body-size reduction. In contrast larger, habitat-generalist caiman species are thermoregulators. This led us to investigate the West African crocodile Crocodylus suchus which is a rather small-sized species that has recently been identified as distinct from the Nile crocodile Crocodylus niloticus, and at least in north-west Africa is a niche specialist inhabiting permanent mountain rock pools (gueltas) and flood plains (tâmoûrts). We compared daily body temperature variations of captive C. suchus and C. niloticus in Morocco and found that, despite a smaller size and habitat specialism, C. suchus is not a thermoconformer but like C. niloticus is an active thermoregulator with marked daily body temperature oscillations. In this regard, we suggest that in crocodiles smaller size per se is not related to a switch from active thermoregulation to thermoconformity.

ABSTRACT: Bachia trisanale is known from western Amazonia in Brazil, Bolivia, Ecuador and Peru. Bachia pyburni is distributed in the north-western Amazon in Brazil, Colombia and Venezuela. Here, we present the first confirmed records of B. trisanale for Colombia, based on three specimens from the Department of Amazonas and one from the Department of Cauca. Additionally, we report a new locality record for B. pyburni and provide comments on the geographic distribution of other species of the genus in Colombia.

ABSTRACT: We report seven opportunistic observations of conspicuous tail-display behaviours in three semi-fossorial skink species (Chalcides ocellatus, Chalcides bedriagai and Chalcides montanus) from Greece, Portugal and Morocco. There were three categories of tail display - tail raised, curling with basal wagging and vigorous horizontal wiggling with tip vibration. These occurred most often when escape was constrained or during brief handling. We suggest that these displays are consistent with an anti-predator, tail-redirecting function.
