Mycorrhizas are the chief organ for plant mineral nutrient acquisition. In temperate, mixed forests, ash roots (Fraxinus excelsior) are colonized by arbuscular mycorrhizal fungi (AM) and beech roots (Fagus sylvatica) by ectomycorrhizal fungi (EcM). Knowledge on the functions of different mycorrhizal species that coexist in the same environment is scarce. The concentrations of nutrient elements ...

The feedback of biodiversity on individual trait variation is a poorly explored mechanistic pathway in ecological research. We analysed the relationship between biodiversity and individual performance by focusing on vocal mimicry, a widespread interaction that may serve in intra- and interspecific communication. We studied the songs of two lark species (genus Galerida) that increase the complex...

A fossil remain of porcupine, a large-sized rodent hitherto unknown in Portugal, was identified during the 2010-13 excavation Last Interglacial deposit Figueira Brava cave. The specimen is left hemimandible retaining PM/4 to M/2 series but lacking incisor and M/3. Based on analysis its morphological odontometric features, we assign Hystrix cristata (Linnaeus, 1758). Nowadays, H. found Africa as...
