Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Associations between mycorrhizal dominance and woody species diversity shift with stand development and climate across subtropical and tropical forests in Taiwan

Ecography, EarlyView.
Mycorrhizal symbioses influence woody species diversity, but whether this association shifts with forest stand development remains underexplored. Using forest inventory data across subtropical and tropical forests in Taiwan, we found that woody species diversity was lower in ectomycorrhizal (EM)‐dominated than in arbuscular mycorrhizal (AM)‐dominated ...

Using multiscale lidar to determine variation in canopy structure from African forest elephant trails [PDF]

Recently classified as a unique species by the IUCN, African forest elephants (Loxodonta cyclotis) are critically endangered due to severe poaching. With limited knowledge about their ecological role due to the dense tropical forests they inhabit in ...

Taxon‐dependent multisite species turnover in fragmented habitats: comparing zeta diversity across birds, butterflies, and cursorial hunting spiders

Ecography, EarlyView.
Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Scale dependency of lidar‐derived forest structural diversity

Methods in Ecology and Evolution, 2023
Lidar‐derived forest structural diversity (FSD) metrics—including measures of forest canopy height, vegetation arrangement, canopy cover (CC), structural complexity and leaf area and density—are increasingly used to describe forest structural ...

Biomass estimation as a function of vertical forest structure and forest height: potential and limitations for radar remote sensing [PDF]

, 2010
One common method to estimate biomass is measuring forest height and applying allometric equations to get forest biomass. Conditions like changing forest density or changing forest structure bias the allometric relations or biomass estimation fails ...

An integrated model of soil-canopy spectral radiances, photosynthesis, fluorescence, temperature and energy balance [PDF]

, 2009
This paper presents the model SCOPE (Soil Canopy Observation, Photochemistry and Energy fluxes), which is a vertical (1-D) integrated radiative transfer and energy balance model. The model links visible to thermal infrared radiance spectra (0.4 to 50 μm)

Forest Drought Resistance Distinguished by Canopy Height [PDF]

, 2018
How are the survival and growth of trees under severe drought affected by their size? While some studies have shown that large trees are more vulnerable to drought than smaller trees, others found that small trees are the more vulnerable. We explored the

Metabolite Profiles and Antioxidant Activity of Dendrobium catenatum Under Simulated Wild Cultivation

Food Safety and Health, EarlyView.
Dendrobium catenatum grown under simulated wild cultivation showed significantly higher flavonoids and stilbenes, leading to enhanced antioxidant activity in both leaves and stems compared to facility‐grown plants. Integrated metabolomics, antioxidant assays, and network pharmacology identified Denbinobin as a key multi‐target antioxidant compound ...
