Una veintena de personas construyen refugios para anfibios y reptiles en la Reserva Biológica de Campanarios de Azaba

Una veintena de personas han participado en la mañana de este sábado 23 de noviembre en la «Jornada de construcción de refugios para anfibios y reptiles» realizada en la Reserva Biológica de Campanarios de Azaba e incluida en el proyecto «Club de fincas en la dehesa del oeste ibérico» que cuenta con el apoyo de la Fundación Biodiversidad del Ministerior para la Transición Ecológica y el Reto Demográfico (MITECO) en el marco del Plan de Recuperación, Transformación y Resiliencia (PRTR), financiado por la Unión Europea-Next Generation EU.

Dark ventral colouration indicates head size in a semi-colonial gecko

I tested for the correlation between the extension of the dark colouration and several morphological traits (body size, head size and limb length) in the gecko, as well as parasitism by mites and age. No relationship was found between dark colouration and parasitism, age and limb length, but the extension of the dark colouration was positively correlated with head size controlled for body size.

Older Amphibian Larvae Are More Sensitive to Ultraviolet Radiation and Experience More Sublethal Carryover Effects Post-Metamorphosis

Irradiance and timing of UVR exposure had interactive effects on larval body length, causing stunted growth patterns and a lack of compensatory growth following UVR exposure, particularly in animals exposed to high irradiance UVR later in development. Timing of UVR exposure also determined the severity of carryover effects into metamorphosis, including delayed metamorphosis and the first published account (to our knowledge) of latent UVR-induced depigmentation in an amphibian.

Latest edition of book offers guidance on monitoring and managing ranaviruses in amphibians, reptiles and fish

Researchers are providing new information and guidance on monitoring and managing viruses that cause life-threatening diseases in amphibians, reptiles and fish, as detailed in the second edition of Ranaviruses: Emerging Pathogens of Ectothermic Vertebrates. Leer más.

Sex-dependent shifts in body size and condition along replicated elevational gradients in a montane colonising ectotherm, the common wall lizard (Podarcis muralis)

While female body size was invariant, females at higher elevation exhibited lower body condition. These results suggest that the effects of abiotic limitations or selective pressures experienced at the high-elevation colonisation front are sex-specific. Leer más.
