Thermoregulating ectotherms may resort to different external heat sources to modulate their body temperature through an array of behavioural and physiological adaptations which modulate heat exchange with the environment and its distribution across the animal's body. Even small-bodied animals are capable of fine control over such rates and the subsequent re-allocation of heat across the body. Such thermal exchanges with the environment usually happen through two non-mutually exclusive modes: heliothermy (radiant heat gain from the sun) or thigmothermy (heat gained or lost via conduction).
View Article and Find Full Text PDFEven though South American Camelids (SAC) are a rustic species, adapted to harsh environments, their ability to reproduce is low in their natural habitat. Conception and birth rates in camelids vary from 50 % to 90 %. This depends on the mating system used, sire and dam fertility, postpartum interval, environmental conditions, and nutrition.
View Article and Find Full Text PDFThis review describes the first steps necessary to apply any reproductive biotechnology in South American camelids (SAC) semen or sperm: sample collection, evaluation and handling. In camelids, the length and position adopted for mating and the site of semen deposition have conditioned semen collection methods. The advantages and disadvantages of available collection methods are summarized.

- Interspecific hybridization poses a risk to the Critically Endangered Aeolian wall lizard, particularly due to its interaction with the invasive Italian wall lizard.
- The largest remaining population resides on Capo Grosso, which is connected to the fully invaded island of Vulcano, raising concerns about hybridization.
- Despite a low hybridization rate of about 3%, there are significant concerns due to low genetic diversity and a small effective population size, highlighting the need for urgent management strategies to protect the species.
Background: Two-thirds of patients with immunoglobulin light chain (AL) amyloidosis have renal involvement. The biochemical profile of kidney damage is poorly described.
Methods: A cross-sectional study was conducted involving patients diagnosed with AL amyloidosis and renal involvement between January 1, 2010, and April 30, 2022 at the Hospital Italiano de Buenos Aires.
