Abstract Vegetation phenology—the seasonal timing and duration of vegetative phases—is controlled by spatiotemporally variable contributions of climatic and environmental factors plus additional potential influence from human management. We used

Abstract Although natural habitats are being lost globally, the extent and fate of natural habitats on private lands in the United States have not been quantified at the resolution relevant for conservation planning. Here we provide information on th

ABSTRACT We revise the taxonomy of species of the ant genus Cephalotes occurring in Brazil. Sixty-four species are recognized, distributed in 14 species groups. Five species are described as new: Cephalotes gabicamacho new species, Cephalotes marycor

Remote Sensing, Vol 14, Iss 5, p 1290 (2022)
Grasslands and shrublands exhibit pronounced spatial and temporal variability in structure and function with differences in phenology that can be difficult to observe. Unpiloted aerial vehicles (UAVs) can measure vegetation spectral patterns relative

Ecological communities vary considerably in space and time and understanding such changes has fundamental relevance for ecology and conservation sciences. Mountains provide an excellent scenario for studies addressing spatial and temporal variation,

Remote sensing can be applied to optimize efficiency in pest detection, as an insect sampling tool. This efficiency can result in more precise recommendations for decision making in pest management. Pest detection with remote sensing is often feasibl

The fate of live forest biomass is largely controlled by growth and disturbance processes, both natural and anthropogenic. Thus, biomass monitoring strategies must characterize both the biomass of the forests at a given point in time and the dynamic

Heavy crown thinning in redwood/Douglas-fir gave superior forest restoration outcomes after 10 years
Publikováno v:
Canadian Journal of Forest Research.
Forest restoration thinning has the potential to enhance the structural complexity and accelerate the development of large trees important to wildlife, aesthetics, and wildfire resistance. These are key objectives for the restoration of even-aged sec

Many organisms divide limited defenses among heterogeneous assets. Plants allocate defensive chemicals among tissues differing in value, cost of defense, and risk of herbivory. Some ant colonies allocate specialized defenders among multiple nests dif

Identifying how the evolution of colony ontogeny is shaped by ecology remains one of the major challenges of sociobiology. Colony size and caste composition are two colony traits generally predicted to undergo substantial ontogenetic change, with an
