The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

A comprehensive checklist of Mediterranean wild edible plants: Diversity, traditional uses, and knowledge gaps

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The use of wild edible plants and the traditional knowledge associated with them are rapidly disappearing across the Mediterranean, with serious consequences for biodiversity, cultural heritage, and regional food security. This study compiles and organizes fragmented information to create the first comprehensive catalogue of these plants across the ...

Biology of \u3ci\u3eDiastrophus Nebulosus\u3c/i\u3e (Hymenoptera: Cynipidae) and Its Parasitoid/Inquiline Complex in Galls on \u3ci\u3eRubus Flagellaris\u3c/i\u3e (Rosaceae) [PDF]

open access: yes, 2018
Rubus flagellaris patches occasionally harbor colonies of compound stem- galls initiated by the cynipid, Diastrophus nebulosus. These isolated colonies host a parasitoid/inquiline complex made up of five principal and three incidental chalcidoid species ...

Brazilian ground pearl damaging blackberry, raspberry and blueberry in Brazil Pérola-da-terra causando danos em amoreira-preta, framboeseira e mirtileiro no Brasil

open access: yesCiência Rural, 2012
The Brazilian ground pearl, Eurhizococcus brasiliensis (Wille, 1922) (Hemiptera: Margarodidae), is a subterranean, polyphagous scale insect native of Southern Brazil that feeds on a variety of different vineyard plant species (Vitis spp.). In this study,

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

open access: yesWildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

open access: yesWildlife Biology, EarlyView.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.
