Summary: Dietary partitioning plays a central role in biological communities and its extent varies over time, possibly due to food availability and seasonality. The study found that dietary partitioning is greatest when food abundance is low, implying competition for limited food resources. The extent of dietary partitioning in birds and mammals is also related to seasonal changes in primary productivity.

Summary: This study investigated the distribution patterns and spatial niche overlap of large grazing herbivores in Gorongosa National Park, Mozambique before and after a 15-year civil war. The findings showed significant changes in range size and spatial niche overlap of these species. The results demonstrate the importance of understanding how human activity can impact species distributions and spatial niche partitioning between coexisting species.

Summary: Small mammals play vital roles in forest ecosystems and their diversity in Romanian forests is influenced by habitat types and tree canopy diversity, with the time dimension being important for related surveys.

Summary: This study explores the ecological and morphological variation of two closely related species, R. spinosissima and R. octofasciata, in the Río Dulce basin. It finds differences in habitat, environmental characteristics, and body shape between the two species.

Summary: To avoid competition, many species possess traits that promote niche differentiation with co-occurring species. By studying a community of spiny lizards in the Chiricahua Mountains of Arizona, USA, researchers found that sympatric species diverge primarily in perch height and type, as well as thermal and temporal resource use. These findings contribute to our understanding of how diverse communities assemble and how morphological diversity accumulates across the tree of life.

Summary: We studied the species limits and taxonomy of the slaty-backed nightingale-thrush Catharus fuscater (Passeriformes: Turdidae), a polytypic complex of songbirds with a broad montane distribution in Central and South America, using datasets of genetic and phenotypic characters. We found 10 allopatric populations that have evolved independently for multiple glacial cycles. Genetic structure is correlated with divergence in phenotypic characters, including plumage colour, iris colour, maxilla (bill) colour, and the acoustic structure of vocalizations. Based on our findings, we propose a taxonomic revision that recognizes seven species in the complex, including a newly described species from eastern Panama, and four subspecies, two of which are newly described.

Summary: This study aims to address the coexistence of competing species in the same foraging guild, focusing on the persistence of small subordinate species with larger dominant competitors. The study found that species are aggregated temporally but segregated spatially, and habitat heterogeneity is a key factor enabling coexistence. The study also suggests conservation measures such as restoring habitat heterogeneity and selecting translocation sites without specific competitors.

Summary: The decline of shark populations in the world ocean has unpredictable effects on ecosystem structure and function, necessitating new ecological information for a better understanding of the role of sharks in their habitats. Research has found that many shark species primarily forage in the mesopelagic area, but the extent to which different pelagic sharks rely on this habitat has been overlooked. By using mercury stable isotopes in the muscle of pelagic sharks, it is possible to reveal their food partitioning and the relationship between foraging depth and resource competition.

Summary: Morphology and phylogenetic distance are more influential on trophic niche overlap, while body size affects niche breadth. Trophic niche breadth is usually smaller when considering prey traits and availability, whereas values of niche overlap increase when these data are not considered.

Summary: The study assessed the potential of the woody nickel hyperaccumulator species Blepharidium guatemalense for agromining in southeastern Mexico. Results showed that the plant has high foliar nickel concentrations, bioconcentration, and translocation factors, making it a prime candidate for nickel agromining. Further studies are needed to confirm the outcomes of pot trials in the field and identify potential viable agromining locations.

Summary: This study explores the interspecific foraging behavior overlap in Fiji's forest birds and finds evidence of vertical stratification of foraging behavior. The results support the significance of interspecific competition and niche divergence for patterns of ecological speciation on islands.

Summary: Diverse plant communities with different spatial water uptake patterns contribute to higher productivity in mixtures compared to monocultures. This is due to niche partitioning of species and complementary root distribution. These findings support the potential of intercropping for sustainable agriculture with more efficient soil resource utilization.

Summary: This study analyzed the diet and distribution of native and exotic Loricariidae fish from a Neotropical floodplain and found that these factors contribute to the coexistence of different species. Differences in diet and resource utilization promote coexistence, but the large population size of exotic species may pose a competitive threat to native species.

Summary: The pine shoot beetles Tomicus piniperda L. and T. minor Hartwig exhibit resource partitioning in forests with different degrees of crown damage, with T. piniperda preferring the thicker part of the stem and T. minor favoring the thinner part. The results suggest spatial specialization in resource utilization by the two beetle species.
