Study reveals ecological keys of a peculiar luminous moss

A scientific team led by a researcher from the Estación Biológica de Doñana - CSIC has compiled all data available for Schistostega pennata, so-called goblin’s gold, and created species distribution models in the Iberian Peninsula.

This unique plant is distributed in only a few areas of the Iberian Peninsula, especially in the north and northwest, and its ecology is still poorly known. Many of its populations are threatened by human activity.

The Cantabrian brown bear's range has expanded up to 17,000 km2 after decades of decline

Researchers at the EBD-CSIC relate the trend to the change of characteristics of the territory occupied by the bears. The study points to the need to adapt management tools for the conservation of the new distribution area of the population of this endangered species. The researchers have observed that while the area with presence of brown bear individuals has increased considerably from the 1990s, the area with presence of bears with cubs has remained stable over time.

Balancing Impacts of Range-shifting Species: Invasive Disruption vs. Biodiversity Benefits

Climate change will cause species to shift their ranges to survive. Although the impacts of range-shifting species can vary from minor to massive, considerations of species movements in the context of climate change has almost entirely focused on positive impacts. This Review uses invasion ecology theory to consider the impacts of shifting species and how to manage these shifts to protect the recipient communities as well as the survival of the shifters. As Earth’s climate rapidly changes,...

Understanding the complex relationships between ecological traits and spatial distribution patterns

The study of the relationship between the ecological niche breadth and spatial distribution of species has been a core topic in ecology. Ecological niche breadth measures the degree of specialisation or generalisation of the resources species use (Eltonian definition of ecological niche) or the conditions which they inhabit (Grinnellian definition). Different domains of the ecological niche, such as climatic tolerance, habitat breadth and dietary breadth, have been shown to be positively...

Iberian amphibians occupy higher mountain areas compared to the last century

extinctions. Amphibians are one of the most sensitive animal groups to climate change, currently undergoing a global decline. Predictive models for Europe and Iberian Peninsula forecast that the future impact of climate change on amphibians will depend on their capacity to alter their distributions by tracking climate warming. In the present study, the responses of Iberian amphibian species to recent climate change are explored by comparing amphibian distributions between two time periods...
