We aimed to determine the relationships between RLI<sub>g</sub> for vegetation with a different cover of forbs, and easily measurable, potential proxy indicators: average canopy height (h), fresh aboveground biomass (FM), and several indices obtained from Sentinel-2 satellites: leaf area index (LAI), normalized difference vegetation index (NDVI), enhanced vegetation index (EVI) and structure insensitive pigment index (SIPI).

A clear pattern of relationship with RLI<sub>g</sub> was observed for h, FM, and LAI: the increase in these parameters coincided with the decrease in RLI<sub>g</sub>. This decrease was strong when h, FM and LAI were still low and became moderate when h, FM, and LAI increased to a certain threshold. This shift in the RLI<sub>g</sub> trend line was more abrupt and occurred earlier in canopies with high herb cover. This relationship can be accurately modeled using a broken line regression.

We analyzed bird and insect acoustic activity at different time scales using passive acoustic monitoring data collected over a year in southern Vietnam. Recordings were made for 5 min every 25 min over 24-h periods, which allowed us to investigate temporal dynamics at daily and seasonal scales. We first calculated acoustic indices for all 5-min recordings across the full dataset. To assess finer-scale interactions, we also sampled 100 recordings representing various times of day and seasons. Then, we assessed the elements of the soundscape (biophony, geophony, and anthropophony) in each recording. Insects and birds were the main elements of the daytime biophony, with insect sounds being most prominent. Insects were active both day and night, but their activity decreased at dawn, when bird activity peaked. We found no negative relationship between insect and bird sound occurrences in the selected recordings, suggesting that birds do not avoid periods of insect activity. Instead, the observed patterns likely reflect distinct circadian rhythms. Furthermore, insects calling at the same frequencies as birds usually do not produce sounds actively at dawn, when birds are the most active.

The study was conducted in 133 plots in two protected areas (Bontioli Total Wildlife reserve and Nazinga Game Ranch) in Burkina Faso. We measured local environmental conditions, species composition and tree structural data (diameter at breast height, maximum height) for each plot. We used combined field observations with wood density values from literature to quantify phylogenetic diversity, functional trait diversity and dominance. We then estimated AGC using established allometric equations. We used structural equation models to assess the direct and indirect impacts of environmental factors on AGC stock, mediated by biodiversity metrics. Aboveground carbon stocks ranged from 5 to 165 Mg/ha, with notable association between phylogenetic diversity and functional trait metrics. These findings underscore the influence of both complementary interactions and trait-based selection. A strong positive relationship between phylogenetic diversity and functional richness across all vegetation types suggest that evolutionary divergence contribute to ecological function. However, the strength and direction of the relationship between phylogenetic diversity and community-weighted mean of maximum height differed among the vegetation types, suggesting that evolutionary influences on trait values are modulated by the unique environmental conditions of each ecosystem.

While this mechanism is known to facilitate the spread of invasive species, it is unclear whether the uphill movement of native plants, in response to rising temperatures, is also aided by reduced herbivory at sites above their current altitudinal range. In our study, we experimentally tested this hypothesis. We compared herbivore damage of six species of lowland plants grown in pots exposed to herbivores at their native sites in the lowland and at sites above their current upper altitudinal limit. As a control, we also measured herbivore damage of six plants growing naturally across the entire range of altitude. We found that lowland plants had reduced herbivore damage when they were moved to highland sites, while herbivore damage of species naturally growing at both altitudes did not differ. Changes of herbivore damage were modulated by leaf dry matter content, specific leaf area and to a lesser degree also by plant height.

The results indicate that, at the habitat level, forests exhibited greater abundance and species richness, and these taxonomic patterns were sensitive to the surrounding land use. Furthermore, the expansion of urban areas in the landscape composition also results in a shift in species composition. Additionally, forest habitats are vital for maintaining higher body condition.
