Combined effects of glyphosate and ambient temperature on the energy management of a lizard: Evidence from a controlled exposure study

Highlights

The joint effects of glyphosate and temperature on a lizard’s metabolism were assessed.
A size-proportional food contamination method was followed.
Standard metabolic rates were measured at 18 °C, 24 °C and 29 °C.
Additive, mass-dependent effects on the energetics of lizards were observed.
Increased energetic costs may compromise reproduction and destabilize populations

La estrecha relación entre la rata negra y el lagarto gigante de Tenerife

A pesar de los efectos nocivos que tiene la rata negra invasora (Rattus rattus) sobre los ecosistemas insulares, el conocimiento sobre su impacto en los reptiles isleños es ciertamente limitado. Leer más.

The Wonder Years: A Demographic Approach to Revisit the Age-at-Size Conundrum in Amphibians

Our demographic approach provided multi-evidence information to address age-at-size estimation in amphibians, thus demonstrating the value of long-term mark–recapture programs to fill pervasive gaps in our knowledge about amphibian demographic dynamics. Leer más.

Skin Colour in Salamanders Is Modulated by Both Epitranscriptomic Methylation and Gene Expression

The fire salamander (Salamandra salamandra) has striking colour patterns and polymorphisms, but the extremely large genome size of salamanders makes traditional genetic analyses infeasible. Leer más.

Clinal Variation in Reproductive Modes and Offspring Body Condition Across a Contact Zone of a Bimodal Viviparous Salamander

We found a gradual and continuous shift in reproductive modes across the contact zone, with “pure” pueriparous mode in the north and larviparous in the south, and mixed reproductive modes in central populations, where hybrids appear to be viable and fertile. Leer más.
