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

Wildlife 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.

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

Wildlife 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.

Landscape distribution and habitat use of sika deer using indirect signs of deer activity: a simple tool for forest managers

Wildlife Biology, EarlyView.
The populations of many deer species across Europe are widely reported to be increasing, leading to potentially greater impacts on forest ecosystems. Our understanding of factors driving the regional distribution (e.g. 1 km2 resolution) of deer populations is, however, often limited by a lack of knowledge of where deer are within the landscape.

Technological alternatives for the control of Botrytis sp. In Andean blackberry (Rubus glaucus)

Enfoque UTE, 2020
The Andean blackberry crop (Rubus glaucus) is very important for the farmers, since they must implement cultural practices that allow reducing the use of synthetic pesticides. The objective of the study was to evaluate the effect of different technological alternatives for the control of Botrytis sp. in the blackberry crop.

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

Ciência 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,

Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Neuroprotective effect of blackberry extract (Rubus sp.) on mechanisms associated with the development and progression of Alzheimer's disease: a study in preclinical models.

, 2023
Alzheimer's disease (AD) is a neurodegenerative, progressive and irreversible disease that leads to memory loss and cognitive decline. Among the pathophysiological mechanisms involved in AD, we can mention cholinergic deficit, neuroinflammation ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...
