Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

This study highlights the importance of the unprotected Yabassi Key Biodiversity Area, Cameroon, for primate conservation in the Gulf of Guinea biodiversity hotspot. We modelled primate distribution patterns and found that historically overlooked parts of the landscape have high species richness and are critical for some threatened species.

2002): Aerosol Mapping Over Rugged Heterogeneous Terrain with Imaging Spectrometer Data
A method for the determination of aerosol optical properties from imaging spectrometer data on a local scale is investigated, making use of the continuous spectral coverage, high spatial resolution, and the well-calibrated radiometry of such data.

In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

Rise of the south: How Arab‐led maritime trade transformed China, 671–1371 CE
Abstract China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re‐creating the South.

The economic foundations of powersharing: Evidence from Africa
Abstract How—and with whom—do rulers share power? Existing research focuses on the strategic logic of powersharing. In this paper, we analyze its economic foundations. Powersharing is modeled as a subnational fiscal contract, in which rulers allocate political representation based on constituencies’ revenue potential. Empirically, we combine historical

IMPACT OF MACHINE-TRACTOR AGGREGATE MOTION PATH ON SOIL EROSION
The paper presents development of measures for prevention of soil erosion with water as a result of wrong mechanical impact of machine-tractor aggregates (MTA) on the arable fields located with inclination and in conditions of rugged area.

We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Individualized Pathfinding in Rugged Open Terrains Using Semantic Navigation Meshes
We introduce semantic navigation meshes for complex outdoor terrains, partitioning space into regions with coherent semantic properties like slope or vegetation density. The resulting graphs enable efficient pathfinding with agent‐specific, parameterized cost functions without precomputation, accelerating search while maintaining path quality close to ...
