Drought-induced shifts in hydroperiod can drastically reduce reproductive success and accelerate larval development with fitness consequences while, on land, desiccation risk and habitat degradation could limit access to refugia and fragment populations by reducing structural connectivity. These environmental constraints are compounded by the interactions between drought and emerging infectious diseases. Leer más.
Cool-and-wet-adapted amphibians were more infected with B. dendrobatidis during warm-and-dry spells, while warm-and-dry-adapted hosts showed higher B. dendrobatidis infection during cool-and-wet spells. For Ranavirus, mismatches occurred under opposite climatic conditions to those of B. dendrobatidis. Leer más.
More than half of the world’s 364 known turtle and tortoise species now face extinction, with the crisis worsening despite global conservation efforts. Asia is the epicenter of the crisis, accounting for 32 of the 66 most threatened species due to intense harvesting, illegal trade and habitat destruction. Leer más.
The species Syriemys lelunensis, newly named under the aegis of the University of São Paulo, dates from the early Eocene, about 50 million years ago. Leer más.
We strongly recommend that eDNA surveys are performed in combination with sequencing efforts to include missing species into reference libraries. Leer más.
