Masting, i.e. interannually variable and synchronized seed production, plays a crucial role in forest ecosystems, influencing wildlife dynamics, pathogen prevalence, and forest regeneration. Accurately capturing masting variability is important for effective forest management, conservation efforts, and predicting ecosystem responses to environmental changes. The adoption of low-cost methods [...]
Cool topoclimates promote cold-adapted plant diversity in temperate mountain forests.
Published: 2024-07-04
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Other Ecology and Evolutionary Biology
Climate strongly influences the composition and diversity of forest plant communities. Recent studies have highlighted the role of tree canopies in shaping understory thermal conditions at small spatial scales (i.e. microclimate), especially in lowland forests. In mountain forests, however, the influence of topography in environmental conditions (i.e., topoclimate) is ought to also influence [...]
Phenological Patterns of Woody Plant Species in a Tropical Dry Forest, Bannerghatta National Park, Bengaluru

Multiple Disturbances, Multiple Legacies: Fire, Canopy Gaps, and Deer Jointly Change the Forest Seed Bank
Published: 2024-05-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences
The manipulation of pre-colonial disturbances in U.S. forests can play a critical role in determining ecological composition, structure, and function. However, our understanding of how concurrent disturbances influence non-tree species is extremely limited in forests. To this end, we used a long-term, multi-disturbance experiment in an oak dominated forest in West Virginia, U.S.A. that [...]
Lianas, to cut or not to cut to conserve forest biodiversity?
Published: 2024-03-17
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences
Although lianas play an important role in forest composition, structure, and functions, they are considered structural parasites of trees. Both contrasting ideas on the role of lianas in forests challenge practitioners during restoration activities and management decisions might be taken without specific information. Here we evaluated the effects of lianas on their host-trees in a small [...]
