Life history attributes influencing metabolic variation in an estuarine fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Considering that energy availability and oxygen transport potential are limited in supplying metabolic requirements, all animals face trade‐offs between competing metabolic demands.

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Rising temperature non‐additively alters how different dimensions of biodiversity affect ecosystem‐scale processes

Journal of Animal Ecology, EarlyView.
The authors distil how dimensions of biodiversity drive ecosystem processes with increasing temperature. Specifically, species physiology more greatly affected ecosystem primary production than did foraging behaviour, and physiology mediated non‐additive interactions with temperature.

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Use of artificial perches for wild birds in a degraded area in southern Brazil

Acta Scientiarum: Biological Sciences
One of the major setbacks in environmental restoration is how to promote the arrival of propagules in degraded areas, and this issue is intensified at sites without vegetation, where natural dispersal is limited.

Environmental Enrichment/Improvement: Effect on Performance of Commercial Broiler Strains [PDF]

Brazilian Journal of Poultry Science
This work reviews the effect of environmental enrichments (perches, platforms, stocking density, outdoor access, bale, and dust bathing substrates) on the performance of fast and slow-growing commercial broiler strains.

Offshore wind farm avoidance by a discard‐feeding seabird is independent of local fishing activity

Journal of Animal Ecology, EarlyView.
Fishing is not allowed within wind farms; therefore, discard‐feeding seabirds may appear to avoid wind farm areas. We found that most Lesser Black‐backed Gulls avoided the wind farm area, but not each individual in each period. Avoidance of the wind farm was not driven by fishing exclusion within its perimeter.

Testing systems of avian perch deterrents on electric power distribution poles in sage-brush habitat

Human-Wildlife Interactions, 2017
In Lincoln County, Washington, USA, greater sage-grouse (Centrocercus urophasianus) and Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) are managed as reintroduced and augmented populations, respectively.

Relationship between spatial and social phenotypes in an avian scavenger

Journal of Animal Ecology, EarlyView.
A method is applied to distinguish interaction rates that would be expected given animals' movements from those that exceed expected values due to incidental contact. The relationship between space use and both observed and non‐incidental social network position varies between social situations.

Resting Behaviour of Parrots Loriculus galgulus

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
This study analysed the preferences of perch size and position in the aviary in a group of 6 lorikeets (Loriculus galgulus). We monitored the presence of the lorikeets in four different locations in the aviary – on the original perches, floor, wire mesh ...
