Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

open access: yesWildlife Biology, EarlyView.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

The complete mitogenome of ceratina smaragdula fabricius, 1787 (hymenoptera: apidae) and phylogenetic analysis of the family apidae base on mitogenome sequences

open access: yesMitochondrial DNA. Part B. Resources
This study describes the mitogenome of Ceratina smaragdula (Hymenoptera: Apidae), which consists of 15,591 base pairs with an AT content of 85.7%. It contains 37 genes, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a control ...

Go High or Go Low? Adaptive Evolution of High and Low Relatedness Societies in Social Hymenoptera

open access: yesFrontiers in Ecology and Evolution, 2017
Cooperative groups can increase fitness either by helping kin or interacting with unlike individuals to produce social heterosis. They cannot, however, simultaneously maximize both benefits.

Differing success of defense strategies in two parasitoid wasps in protecting their pupae against a secondary hyperparasitoid

open access: yes, 2011
During their larval development, endoparasitoids are known to dispose of host resources in several different ways. Some parasitoid wasps consume most or all tissues of the host, whereas others consume a small fraction of host resources and either ensure ...

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

open access: yesWildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Spiders in a hostile world (Arachnoidea, Araneae) [PDF]

open access: yes, 2011
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders.

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering
