Concrete jungle to urban oasis: evaluating scale, vegetation cover, and aggregation of urban greenspaces on wildlife

Wildlife Biology, EarlyView.
Urban greenspaces are a haven for wildlife in densely populated cities. Wildlife use greenspaces for resource acquisition, shelter, and travel across urbanized landscapes. Greenspace metrics such as herbaceous or woody landcover, size, patchiness, and human land use influence species richness.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

High nitrogen loading impacts the temperature‐size rule and heat tolerance in a nettle‐feeding butterfly

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host‐plant quality and ambient temperature are key environmental drivers of herbivorous insect performance, affecting growth, development, and survival. While temperature accelerates physiological processes in ectothermic insects, nutrient limitation in host plants can ...

Trace Metals in Nectar of Important Urban Pollinator Forage Plants: A Direct Exposure Risk to Pollinators and Nectar‐Feeding Animals in Cities

Ecology and Evolution
Pollinators are exposed to metals while foraging in the landscape and accumulate detectable concentrations of trace metals within their bodies, although major exposure routes remain unclear.

Just graze it! Biodiversity, nectar and forage resources in cultural landscapes grazed by different livestock species

Ecosystems and People
The Nordhordland UNESCO Biosphere Reserve encompasses a heterogeneous landscape which provides numerous ecosystem services. Semi-natural grasslands provide forage for traditionally managed livestock and are important sources of nectar and pollen for ...

Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

Journal of Animal Ecology, EarlyView.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...

I've been robbed! - Can changes in floral traits discourage bee pollination?

PLoS ONE, 2019
Some floral visitors collect nectar by piercing flower external whorls, acting as nectar robbers. They leave robbery vestiges, which can cause changes in floral characteristics, including physical and chemical signals that may influence flower ...

Leukocyte profiles reveal sex and age differences in immune investment in a polygynous bat

Journal of Animal Ecology, EarlyView.
Analysis of over 500 blood cell profiles, including repeat samples over four years, reveals that male bats from a long‐lived species with a polygynous mating system invest more in innate than adaptive immunity. Investment in innate immunity increases with age, as estimated by a DNA methylation clock and mark‐recapture data.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
