Estructura, diversidad y dinámica de la vegetación en el ecotono bosque-páramo: revisión de la evidencia en la Cordillera de Mérida [PDF]

Acta Biológica Colombiana, 2015
En los Andes tropicales, el límite altitudinal de los bosques corresponde a una compleja zona de transición entre el bosque paramero y el páramo andino.

Long transient response of vegetation dynamics after four millennia of anthropogenic impacts in an island ecosystem. [PDF]

Glob Chang Biol, 2022
In the Mediterranean region, island ecosystem dynamics have been influenced by millennia of anthropogenic impacts. Here, we analysed the spatio‐temporal dynamics of vegetation in sa Dragonera, where herbivory by goats, over‐logging and rat occurrence ended in the last decades.

Las pirámides de vegetación como indicadoras de la dinámica ambiental

Aula, 2009
RESUMEN: Las pirámides de vegetación son un excelente instrumento didáctico para analizar las complejas interacciones que se dan en un paisaje y la importancia que han tenido los hábitos de explotación humanos en la configuración de los espacios de ...

Toward a functional understanding of novel fire regimes in tropical forests. [PDF]

Am J Bot
Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

Habitat dynamics of flagship species for conservation prioritization in southern Europe. [PDF]

Conserv Biol
Abstract Biodiversity loss is accelerating due to human actions, and decision‐making for conservation needs to be streamlined. Ex situ biodiversity modeling and monitoring based on satellite time‐series data could be an affordable and cost‐efficient tool for improving the prioritization of conservation areas.

Coexistence across space and time: Social‐ecological patterns within a decade of human‐coyote interactions in San Francisco

People and Nature, Volume 5, Issue 6, Page 2158-2177, December 2023., 2023
Abstract Global change is increasing the frequency and severity of human‐wildlife interactions by pushing people and wildlife into increasingly resource‐limited shared spaces. To understand the dynamics of human‐wildlife interactions and what may constitute human‐wildlife coexistence in the Anthropocene, there is a critical need to explore the spatial,

Effects of seagrass restoration on coastal fish abundance and diversity

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Restoration is accelerating to reverse global declines of key habitats and recover lost ecosystem functions, particularly in coastal ecosystems. However, there is high uncertainty about the long‐term capacity of restored ecosystems to provide habitat and increase biodiversity and the degree to which these ecosystem services are mediated by ...

Berries and bullets: influence of food and mortality risk on grizzly bears in British Columbia Bayas y balas: influencia de la alimentación y el riesgo de mortalidad en los osos grizzly en la Columbia Británica Des baies et des balles: influence de l'alimentation et risques de mortalité chez les ours grizzlys de la Colombie‐Britannique

Wildlife Monographs, Volume 213, Issue 1, November 2023., 2023
We developed a spatialized surface for the primary food of grizzly bears in southeast British Columbia. After using this huckleberry patch layer to model habitat selection, fitness, and density, in a bottom‐up top‐down paradigm, we found that huckleberry patches near forestry roads contribute very little to fitness and density.

Combined impacts of future climate‐driven vegetation changes and socioeconomic pressures on protected areas in Africa

Conservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Africa's protected areas (PAs) are the last stronghold of the continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land‐use change. Conservation planning is challenged by uncertainty about how strongly and where these drivers will interact over the next few decades.
