Interactions between plants and animals allows species to survive

A study from the EBD-CSIC and the UCA experimentally proves that the way species interact determines the way they coexist
Results indicates that any change introduced in an ecosystem radically alters the behaviour of species in a way that is difficult to predict

Interspecific interactions determine the range-wide distribution and genomic variation in two Californian oaks

Organisms interact with each other in very different ways. These interactions include, among many others, those established between prey and predators, hosts and parasites, and plant roots and beneficial mycorrhizal fungi. Plants also interact among them, competing for resources (e.g., water, light or nutrients) or creating a favorable environment (e.g., shade) that facilitates the establishment and survival of seedlings from other species. Although classic ecological studies have profoundly...

Invasive plants and urban development: a bad combination for coastal vegetation

Land-use intensification and biological invasions are two of the most important global change pressures driving biodiversity loss. However, their combined impacts on biological communities have been seldom explored, which may result in misleading ecological assessments or mitigation actions. Based on an extensive field survey of 445 paired invaded and control plots of coastal vegetation in SW Spain, the joint effects of land-use intensification (agricultural and urban intensification) and...

Understanding resident and migratory bird populations responses to climate warming

Many organisms adjust their reproductive phenology in response to climate change, but phenological sensitivity to temperature may vary between species. For example, resident and migratory birds have vastly different annual cycles, which can cause differential temperature sensitivity at the breeding grounds, and may affect competitive dynamics. Currently, however, adjustment to climate change in resident and migratory birds have been studied separately or at relatively small geographical...

Spatial segregation important mechanism for reducing competition in petrels

Según la teoría del nicho ecológico, existen mecanismos que permiten la coexistencia de los organismos que de otro modo competirían por las mismas presas y otros recursos. Cómo las aves marinas de pequeño tamaño compiten por los recursos en la época no reproductiva había sido poco estudiado hasta ahora. Por primera vez se aborda papel potencial de la segregación espacial, medioambiental (cambio de hábitat) y trófica (cambios isotópicos) en la partición del nicho ecológico de cuatro aves...
