Big Bird: A global dataset of birds in drone imagery annotated to species level
Remote Sensing in Ecology and Conservation, EarlyView.Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Scaling and width distributions of parity-conserving interfaces [PDF]
, 2013 We present an alternative finite-size approach to a set of parity-conserving interfaces involving attachment, dissociation, and detachment of extended objects in 1+1 dimensions. With the aid of a nonlocal construct introduced by Barma and Dhar in related

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane
Small, EarlyView.Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Structured and Unstructured Binding of an Intrinsically Disordered Protein as Revealed by Atomistic Simulations [PDF]
, 2016 Intrinsically disordered proteins (IDPs) are a set of proteins that lack a definite secondary structure in solution. IDPs can acquire tertiary structure when bound to their partners; therefore, the recognition process must also involve protein folding ...

Drivers of phenological transitions in the seedling life stage
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional ecology research has primarily focused on juvenile and adult plants even though regeneration from seed can be the most consequential life‐history bottleneck with cascading influence on later stages of growth and reproduction.

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.
