Beyond discrete visibility estimates: single‐scan LiDAR provides an efficient method for 3D viewshed estimation

Wildlife Society Bulletin, EarlyView.
We demonstrated a new approach for estimating fine‐scale 3‐dimensional (3D) visibility based on single scans from a terrestrial laser scanner. Our method produced results that were comparable to traditional 2D visibility estimates assessed with profile boards but provides comprehensive information across all directions and continuous distances ...

[On the origin of the name Girifalco, an Italian town in a hotspot of the autumn migration of soaring raptors]

Natural History Sciences
In this article, a hypothesis is suggested on the origin of the name Girifalco, a small town in the Calabrian Apennines (southern continental Italy), located along an important flyway of raptors migrating through the Central Mediterranean. In particular,

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

Wildlife Society Bulletin, EarlyView.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Bergmann's rule: Why does body size increase with latitude?

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bergmann's rule describes the tendency for endothermic body size to increase with latitude, a pattern often attributed to climatic factors. However, the underlying developmental and evolutionary mechanisms remain debated.

Preen oil chemical composition encodes individuality, seasonal variation and kinship in black kites Milvus migrans

Journal of Avian Biology, 2018
Evidence that bird odour can encode social information that can be used in chemical communication is growing, but is restricted to a few taxonomic groups. Among birds, diurnal raptors (i.e.

To stay or to roam? Behavioural type influences trade‐offs in male wild turkey survival

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals develop familiarity with specific areas through repeated use, gaining detailed knowledge of local conditions, such as food availability, predator presence, and landscape features, which can directly impact fitness.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Movement Models to Predict Low-Altitude Flight of Soaring Birds Using Look-Ahead Environmental Factors. [PDF]

Ecol Evol
Eagles see ahead. Now our model does too. By modeling how eagles respond to terrain and wind conditions in their line of sight, we can predict where they'll fly in the next 3 min with 3× better accuracy than current methods—protecting eagles while maximizing energy production.

Differences in Habitat Quality Drive Behavioral Contrasts in Two Family Groups of the Critically Endangered Hainan Gibbon (Nomascus hainanus)

Integrative Zoology, EarlyView.
Habitat quality variation drove distinct behavioral strategies: GC (resource‐rich group) behaviors were influenced by food availability, safety and stability, while GE (resource‐scarce group) behaviors relied more on topography, food, and nutrients. Seasonal behavioral flexibility was demonstrated, with food variables dominating in the dry season and ...
