The intensity of a pathogen infection plays a key role in determining how the host responds to infection. Hosts with high infections are more likely to transmit infection to others, and are may be more likely to experience progression from infection to disease symptoms, to being physiologically compromised by disease. Understanding how and why hosts exhibit variation in infection intensity therefore plays a major part in developing and implementing measures aimed at controlling infection spread, its effects, and its chance of persisting and circulating within a population of hosts.

En España, hay tres especies de víboras, las tres pertenecientes al grupo de las víboras europeas (género Vipera)”, explica el herpetólogo e investigador Fernando Martínez Freiría, que investiga la biogeografía, ecología y conservación de las víboras ibéricas. “Aunque las tres especies de víboras ibéricas son ecológicamente muy similares, están adaptadas a distintas condiciones climáticas y presentan una distribución parapátrica entre sí, esto es que cada una está distribuida en una región y apenas solapan sus distribuciones.

Enseñar cómo contribuir a salvar los anfibios que se quedan atrapados en la piscina del área recreativa de Sollovio era uno de los objetivos de las actividades que ayer realizó el Grupo de Ornitología Mavea con motivo del Día Internacional de los humedales, acontecido esta semana. Leer más.
In 1847, Dufour proposed the nomen Salamandra tuberculata, a senior synonym of Hemitriton asper, for the taxon currently recognized as Calotriton asper (Dugès, 1852). In order to sustain stability, the predominant usage should be maintained. We present here the conditions required by article 23.9 of the International Code of Zoological Nomenclature for the reversal of precedence. Leer más.
