Summary: The study in Chilean Patagonia found that domestic sheep exhibit behavioral changes in response to herd size, food availability, and the presence of guanaco. These changes are primarily driven by intraspecific competition among the sheep rather than interspecific competition with guanaco.

Summary: Climate and competition influence species' performance and distribution, with precipitation playing a significant role in the growth of sugar pine. While stable niche differences were observed in dry years, positive frequency dependence was evident in wet years, highlighting the complexity of interactions between climate and species coexistence.

Summary: Tropical islands, including Maio in Cabo Verde, are home to a significant number of endemic species. However, increasing threats such as habitat loss, disturbance, and introduced predators have put these species at risk, making long-term demographic studies essential. A 13-year investigation of Kentish plover nests on Maio revealed that nest survival differed between habitats, with salt-extraction areas showing higher survival rates. Breeding densities and nest survival of the plovers have declined over the years, likely due to predation and human disturbance. To ensure the persistence of this population, conservation efforts should include traditional management practices and predator control on tropical islands.

Summary: This paper examines a population model consisting of two predators and one prey, taking into account both inter-specific and intra-specific competition. It is found that with intra-specific competition, coexistence of the two predator species becomes possible, and they may maintain at two different equilibrium populations.

Summary: Under limited resources, even neighboring populations of the same species face strong competition, with intra-specific competition being more intense than inter-specific competition due to a lack of niche partitioning. The overlap in foraging space was larger between different species compared to within each species, suggesting that diets of conspecifics from different colonies remained similar despite spatial segregation.

Summary: This study investigated the annual survival and cause-specific mortality of the European wildcat, finding that human-caused mortalities, such as roadkill and poaching, were the main risks. The research showed that road density strongly impacted wildcat annual survival, with motorways and primary roads posing the highest risk. These findings provide important information for conservation planning and highlight the need to maintain subcritical road densities in key wildcat habitats.

Summary: When multiple species with similar trophic niches co-occur in an ecosystem, partitioning of foraging, refuge, and breeding microhabitats is predicted. This study examines the potential niche partitioning among stream salamanders with a bi-phasic natural history. The results show inter- and intra-specific dietary overlaps among the stream salamander community, suggesting selection for species- and life-stage-specific foraging microhabitats.

Summary: This paper discusses a Lotka-Volterra model with density-dependent motion. Under homogeneous Dirichlet boundary conditions, which differ from a previous article (Liu and Guo, 2021), the corresponding steady-state problem is analyzed. The stability properties of the trivial and semitrivial solutions are fully determined. Sufficient conditions for the existence of coexistence solutions are obtained using the theory of fixed point index in positive cones. Finally, the limiting behavior of coexistence solutions is studied as certain parameters tend to infinity. (c) 2023 Elsevier B.V. All rights reserved.

Summary: The study found that factors such as population density, food availability, and weather have a significant impact on population change in a wide range of species. Understanding the interplay between these drivers is essential for effective conservation and management strategies. Using long-term data from five hazel dormouse populations in Europe, the researchers examined the relationship between population density, weather, and demographic rates. They found that higher population density, precipitation, and winter temperature had negative effects on population growth rates, indicating that warmer and wetter weather negatively impacts dormouse survival. The researchers also observed an interaction between weather measures and population density on age-specific survival, possibly due to weather impacts during hibernation.

Summary: Sex-specific morphs exhibit unique sexual dimorphism and diversity in animals. Recent genomic and transcriptomic studies have shed new light on the evolutionary origin and development of sex-specific morphs. These morphs have evolved independently in different animals and are often associated with alternative mating strategies. The diverse nature of sex-specific morphs provides opportunities to understand the genetic basis of complex phenotypes.

Summary: Increasing elephant populations result in a loss of tree carbon storage, but contrary to the second hypothesis, soil organic carbon stocks actually increase with higher elephant densities. This increase in SOC is mainly found in the topsoil and is due to the formation of SOC from woody biomass.

Summary: This study proposes a methodology to estimate woody aboveground biomass (AGB) in disturbance-prone ecosystems and compares it with a less adapted forest inventory method. The results show that methods tailored to disturbance-prone environments are necessary for accurate AGB estimation in savanna vegetation, and that disturbances significantly impact woody AGB.

Summary: Instrumental data shows that groundwater and lake levels in Northeast Germany have been decreasing, with an accelerated rate in recent years. Besides global warming, the direct impact of human activities on the local water balance is suspected to be a contributing factor. This study quantitatively reconstructs the surface water areas in the Lower Havel Inner Delta and Lake Gulpe in Brandenburg using historical and modern maps from 1797 to 2020. The major finding is a continuous decline in surface water areas by approximately 30% since the pre-industrial period. It is suggested that comprehensive measures in Lower Havel hydro-engineering correspond to the groundwater lowering, and large-scale melioration measures in the upstream wetlands may have amplified the decline in downstream surface water areas.

Summary: This study investigated the relationship between phenology and functional traits in 212 plant species across five botanical gardens in Germany, finding that closely related species showed greater similarities in timing of phenological events, but species' traits had a high degree of explanatory power, indicating the importance of species' life-history strategies. Taller and large-leaved plants exhibited later phenology and higher competitiveness.

Summary: Nature conservation in Sub-Saharan Africa, particularly focused on elephants, has led to increases in soil organic carbon stocks due to the input of decaying wood and dung. This study found that the increasing densities of elephants were associated with rising contents of lignin-derived phenols in the soil, indicating the accumulation of plant residues. However, agricultural intensification had the opposite effect. The input of woody residues into soil by browsing elephants is an important mechanism for controlling soil organic carbon supply in the context of wildlife conservation.
