The evolution of montane vegetation in the eastern sector of the Ayllón massif (Central Mountain Range). Pollen analysis of a core from Pelagallinas peatbog

open access: yesAnales del Jardín Botánico de Madrid, 2001
Pollen and charcoal analyses of a core from Pelagallinas peatbog, located in the Sierra de Alto Rey at the eastern sector of the Central Mountain Range (Guadalajara), show the environmental history of the montane vegetation during the last 4000 years ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Responses of the germination and phytochemical content of Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe. (Anatolian black pine) seeds to salt stress

open access: yesJournal of Forest Science, 2022
The germination stage, which is known to be the most sensitive period of plant development, is very sensitive to salt stress. To determine how salt stress affected the germination behaviour of Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe, the seeds

TreeMig framework ver. 1.0: an R package with GUI to simulate spatio‐temporal forest dynamics

open access: yesEcography, EarlyView.
Spatio‐temporal vegetation models are essential for simulating dynamics and shifts in species distributions over large areas, particularly under global change. One such model is the dynamic forest landscape model TreeMig. We have developed a framework that makes the model more user‐friendly, improves its functionality, and expands its possibilities ...

Estimation of above-ground biomass in dry temperate forests using Sentinel-2 data and random forest: a case study of the Swat area of Pakistan

open access: yesFrontiers in Environmental Science
Accurate mapping of above-ground biomass (AGB) is essential for carbon stock quantification and climate change impact assessment, particularly in mountainous areas.

Simulating past and future refugia for temperate trees in northern Italy

open access: yesEcography, EarlyView.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...
