Automated Detection and Monitoring of Ground-Nesting Bee Nests Using Drone Imagery and Deep Learning. [PDF]

Ecol Evol
We demonstrate the feasibility of integrating drone‐based image acquisition with deep learning to accurately detect soil mounds produced by ground‐nesting bees, indicating nest presence, and reliably distinguish them from other soil surface deposits. This approach has the potential to gain new insights into bee nesting biology and population dynamics ...

Sphaerochara canadensis (Charophyceae): A circumpolar species with a high temperature optimum. [PDF]

J Phycol
Abstract Sphaerochara canadensis, an aquatic macrophyte belonging to the Characeae, is described as a species with a circumpolar distribution and occurs in the polar (to boreal) zonobiomes, suggesting that it is cold‐stenothermic. A recent report of an occurrence in Lake Wolfgangsee, Austria, contradicted this assumption, prompting this study to ...

Neural Dynamics of Relational Memory Retrieval Across Eye Movements. [PDF]

Psychophysiology
ABSTRACT Relational memory retrieval entails a dynamic interplay between eye movements and neural activity, yet the temporal coordination of these processes remains unclear. We examined how theta‐ and alpha‐band EEG activity relates to sequential fixations during relational memory retrieval.

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

Wildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Welfare assessment of turkeys (Meleagris gallopavo gallopavo) on farm

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract This Scientific Opinion assesses the welfare of turkeys of all ages (Meleagris gallopavo gallopavo) on farm in relation to the type and condition of the litter, type and availability of enrichment (including covered veranda and outdoor range), space allowance, concentrations of ammonia and carbon dioxide, effective environmental temperature ...

Red deer adult sex ratio: comparing three approaches using camera trap data

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
A naïve estimate of the adult sex ratio in red deer (Cervus elaphus) using raw camera trap data showed no bias when compared to more advanced statistical methods that account for detection probabilities or predict the sex of unknown sightings. Abstract European forests face severe challenges due to climate change, highlighting the importance of tree ...

Advice on animal and public health risks of insects reared on former foodstuffs as raw material for animal feed

Food Risk Assess Europe, Volume 4, Issue 1, January 2026.
Abstract In the coming decades, there is expected to be a sharply increased demand for dietary proteins for humans and animals. As a result, there is an increasing focus on reared insects as a new source of protein. According to the Ministry of Agriculture, Nature and Food Quality (LNV), the use of food chain residual flows such as former foodstuffs as

Genetic and phenotypic comparison of natural and translocated populations of a pond‐breeding amphibian

Conservation Science and Practice, Volume 7, Issue 12, December 2025.
The translocations resulted in populations that do not differ much from natural populations in their genetic structure and fitness‐related life history traits. Abstract Translocations are a commonly used method in conservation practice and are often viewed as successful if a new population persists.

Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

The Depositional Record, Volume 11, Issue 5, Page 1451-1478, November 2025.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

Massenbegriffe auf dem Prüfstand: Die drei Facetten der Masse

Physik in unserer Zeit, Volume 56, Issue 6, Page 272-280, November 2025.
Masse ist die primäre Eigenschaft, die man physikalischen Körpern zuordnet. Da die Masse verschiedene Rollen übernimmt – so reagiert sie nicht nur auf ein Gravitationsfeld, sie erzeugt auch eines –, müssen diese verschiedenen Rollen und darauf aufbauend die verschiedenen Massenbegriffe genauer analysiert werden.
