Using metapopulation theory for practical conservation of mangrove endemic birds. [PDF]

Conserv Biol, 2020
Abstract As a landscape becomes increasingly fragmented through habitat loss, the individual patches become smaller and more isolated and thus less likely to sustain a local population. Metapopulation theory is appropriate for analyzing fragmented landscapes because it combines empirical landscape features with species‐specific information to produce ...

Native palms and trees mediate drought impacts on dry neotropical pastures

Journal of Applied Ecology, Volume 60, Issue 7, Page 1376-1387, July 2023., 2023
Abstract Dry forests are the most threatened biome across the global tropics. Despite their massive conversion into agricultural landscapes, local farmers often retain disperse trees and palms within grazing pastures. Understanding how on‐farm tree cover in the dry neotropics impacts the environmental and productive functions of pastures is key for ...

Forest disturbance and recovery in Peruvian Amazonia

Global Change Biology, Volume 29, Issue 13, Page 3601-3621, July 2023., 2023
This study used Landsat time series in combination with data from 1840 National Forest Inventory plots in Peruvian Amazonia to determine the impact of disturbance, environmental conditions and human use on forests' biomass and tree diversity. We found that the intensity of forest disturbance had a negative effect on the recovery of aboveground biomass ...

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.

From the ground up: Patterns and perceptions of herbaceous diversity in organic coffee agroecosystems

Ecological Solutions and Evidence, Volume 3, Issue 3, July–September 2022., 2022
Smallholder farms that transition to organic and biodiverse production are increasingly recognized as strongholds of agrobiodiversity. Yet the emergent herbaceous communities in these organic systems remain understudied, with the functional diversity and management of this stratum relatively unknown.
