Parasites hinder reproduction for seabird mothers
By University of Liverpool 7/19/2019 A study by the University of Liverpool and Centre for Ecology & Hydrology (CEH) has found that parasites reduced female seabirds’ reproductive success by 30%, whilst seeming to have little effect on male seabirds. A seven year study of European shags on the Isle of May off the East coast of Scotland sought to explore the impact…

Lionfish ear-bones reveal a more mobile invasion
Lionfish in Florida are an underwater force to be reckoned with. The biggest threat they pose is not their venomous spines – it is the alarming speed and ferocity with which they invade new waters.

Ecological Applications
Species can be partitioned into coherent groups to better understand impacts of habitat conversion on biological communities. In the July issue of Ecological Applications, Frishkoff and Karp show bird responses to habitat conversion are species-specific, nonlinear, scale-dependent, and context dependent.

Ecological Monographs
The relationship between animals and their gut flora is simultaneously one of the most common and most complex symbioses on Earth. In the May 2019 issue of Ecological Monographs, Ravenscraft et al. characterize variation of the gut microbiota within and among butterfly species, increasing our understanding of how this hidden symbiosis affects and is affected by its host.

Ecosphere
In the June issue of Ecosphere, Sweet et al. used field measurements and statistical models to predict the distribution of continuously suitable conditions at the end this century for Yucca brevifolia, the iconic species of Joshua Tree National Park. Future species distribution models based on end-of-century downscaled global climate models show that the suitable area for Y. brevifolia will likely be reduced to 80% of the historic range within the park, indicating the importance of maintenance of refugial areas for Joshua trees.

Frontiers in Ecology and the Environment
Wildfires can be destructive but they also promote diverse populations of flowering plants, including the California poppy (Eschscholzia californica), which in turn support a variety of pollinators, such as the European honeybee (Apis mellifera). In the June issue of Frontiers, Pausas and Keeley describe the abundance of ecosystem services that natural fire regimes provide, and discuss the advantages of living in a flammable world.

Ecology
In the July issue of Ecology, Smith et al. test how habitat distribution influences the predator-prey space race by examining correlation in puma and vicuña habitat selection and space use. Their findings further discussion on the dynamics of predator-prey response races in large vertebrate communities and the implications on broader ecological interactions.
