Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Urban Forests and Environmental Challenges in the Last Decades in Brazil: Insights for the National Urban Forestry Plan

open access: yesSustainable Development, EarlyView.
ABSTRACT National afforestation policies are crucial for outlining guidelines and goals to be implemented at the local level. Therefore, it is crucial to conduct research that systematizes indicators from across the country into a single proposal. This study examines the spatiotemporal distribution of urban forest research in Brazil from 1980 to 2020 ...

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the
