“…Numerous factors such as habitat fragmentation, land use land cover, competition, predation and food resource availability influence the community structure of bird feeding guilds in human-dominated landscapes (Bhakti et al, 2021;Kurucz et al, 2021;Suttidate et al, 2023). Food resource availability is one of the most critical factors in the distribution and habitat use by specialist and generalist birds in all ecosystems (Galbraith et al, 2015;Wang et al, 2022).…”

Habitat heterogeneity plays a vital ecological role in influencing community ecology dynamics. We evaluated the relationship between habitat heterogeneity and land‐use cover with avian community structure in the human‐dominated landscape of the Katavi‐Rukwa ecosystem in Tanzania. We used the fixed‐radius point count method to record birds in different habitats. We calculated the relative abundances and the Shannon‐Wiener diversity index of bird guilds across habitats as well as the Normalised Difference Vegetation Index (NDVI) and estimated land‐use cover of the study area from Landsat 8 images. We grouped birds into five major guilds: Insectivore, Granivore, Omnivore, Carnivore and Nectarivore. Among the guilds, Insectivores, Omnivores, Nectarivores and Carnivores were positively correlated with an increase in NDVI, while Granivores were negatively correlated with an increase in NDVI. Among the habitats, woodland had high species diversity whereas riverine had low species diversity. Our findings highlight the importance of habitat heterogeneity in biodiversity conservation in human‐dominated landscapes, and we suggest implementing conservation in these landscapes.

“…For bird species that are more likely to occupy upland habitat that is unsuitable for L. subcoriacea recruitment, the permeabilitybased movement method would result in lower SDE. We evaluated the potential usefulness of this more nuanced simulated disperser movement, as there are few published examples of models that incorporate both animal movement and environmental heterogeneity to describe seed dispersal [24,29,53,54]. We also conducted experiments comparing dispersal when disperser species were parameterized with distinct vs. the same physiological parameters to parse the effects of physiology (e.g., gut capacity, SRT, and flight speed) versus environmental heterogeneity on seed dispersal.…”

The primacy of endozoochory for the maintenance and expansion of many woody plant populations is well known, but seed dispersal is not well understood for most species. This is especially true for rare species, where small population size and low fruit production can limit field- or observation-based experiments. Additionally, the effect of environmental heterogeneity on disperser movement is rarely investigated but has been shown to improve estimates of plant population spatial patterns and dynamics. We used simulation experiments to explore the effects of environmental heterogeneity and disperser movement on Lindera subcoriacea seed dispersal, a rare shrub from the southeastern United States with avian-dispersed seeds. Our experiments incorporated environmental heterogeneity and simulated disperser movement for five bird species, based on either landscape permeability or straight path rules. We anticipated that permeability-based movement would result in greater dispersal distances and seed dispersal effectiveness, which characterizes both quantity and quality. Generally, we did not find differences in seed dispersal between permeability and straight path experiments. However, we did find that permeability-based experiments had greater deposition into suitable habitat during flight (23 vs. 1%). These rare but longer distance depositions may be especially important for plants that are influenced by gap or interpopulation dynamics. We also found consistently greater dispersal into high quality habitats regardless of disperser species in permeability experiments, implying that incorporating species-specific assessments of landscape utilization (occupancy) could influence the effectiveness of seed dispersal. Our study suggests that including environmental heterogeneity in seed dispersal models can provide additional insights not provided by avian parameters (e.g., gut capacity, seed retention time, and flight speed) commonly used to inform dispersal models.
