Retrospective image analysis for long‐term demography using Google Earth imagery
Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Sustainable Development, EarlyView.ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Wildlife Biology, EarlyView.One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Pirineos: Revista de Ecología de Montaña, 2006 Hemos llevado a cabo la cartografía de la vegetación alpina a escala media (nivel de cuenca experimental) mediante interpretación remota. Esta metodología plantea dificultades debido a la distribución en mosaico de la vegetación y a la heterogeneidad del

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Wildlife Biology, EarlyView.After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Identifying multidisciplinary research gaps across Arctic terrestrial gradients
Environmental Research Letters, 2019 Global warming is driving environmental change in the Arctic. However, our current understanding of this change varies strongly among different environmental disciplines and is limited by the number and distribution of field sampling locations.

Determining Subarctic Peatland Vegetation Using an Unmanned Aerial System (UAS)
Remote Sensing, 2018 Rising global temperatures tied to increases in greenhouse gas emissions are impacting high latitude regions, leading to changes in vegetation composition and feedbacks to climate through increased methane (CH4) emissions.

Wildlife Biology, EarlyView.Human activities have shaped and are continuing to influence terrestrial landscapes, creating heterogenous, and often, fragmented landscapes. Generalist species, like the red fox Vulpes vulpes, show high flexibility in habitat use, and occur across the heterogeneous, anthropogenic landscapes of central Europe.
