Summary: Theory suggests that competing species can coexist in a community when intraspecific competition is stronger than interspecific competition. This study found that the evolution of species- and size-dependent competitive asymmetries increased the likelihood of coexistence between interacting species. Furthermore, the research highlights the importance of integrating evolution and trait-based interactions into studies on species coexistence.

Summary: A major question in ecology is how often competing species reduce competitive interactions and facilitate coexistence. This study investigates the effect of ontogenetic changes in trophic niche on the coexistence of two fish species. The findings provide comparative evidence for the role of ontogenetic niche shifts in species coexistence and suggest contemporary evolution in these shifts.

Summary: The distribution of fruit pigeons on the island of New Guinea is influenced by geographical accessibility. The coexistence of species in a particular year and location is a nonrandom selection process. The sizes of these species are more widely spread and evenly spaced compared to random sets of species. Additionally, the local status of a highly mobile species decreases as other resident species become more closely related.

Summary: Contrary to predictions, male California sea lions have increased their average body size over a 46-year recovery period, which is related to density-dependent sexual selection and an expanding foraging niche. Female California sea lions, however, have maintained stable skull dimensions, possibly due to the need for a stable body size during reproduction. This study shows that body size reduction is not a universal response to population recovery in marine mammals.

Summary: Recent studies show that rapid contemporary evolution can regulate species coexistence through a balance between temporal fluctuations and competitive ability versus adaptive evolution speed. This interaction expands the range of coexistence conditions and stability, providing a solution to the paradox of the plankton.

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: This paper examines the conflict and coexistence between people and elephants in the Morogoro Region of Tanzania. The study analyzes the factors that influence human-elephant interaction and the attitudes of subsistence farmers towards elephants in different villages. The research reveals a shift in attitudes towards elephants and identifies the variables that influence tolerance levels in different communities.

Summary: We studied structured competition models that allow life history parameters to depend on adult or juvenile population densities. We found that stage structure can promote coexistence, but this mechanism is not common in diverse ecosystems with multiple species.

Summary: The recent debate over the role of trade in economic growth and inequality has focused on whether the gains from trade outweigh the disruptions caused by necessary adjustments. While static gains from trade may be underestimated, the dynamic gains in promoting faster economic growth in both developed and developing countries through competition and innovation are crucial. The need to reassess industrial policies and examine spillover effects in the global economy is emphasized, especially in the context of significant technological disruption and the recent policy responses to the COVID-19 pandemic.

Summary: Using a trait-based marine ecosystem model, the study reveals that future oceans, especially in tropical regions, will favor food webs dominated by carnivorous and gelatinous filter-feeding zooplankton, which will partially offset the decline in phytoplankton biomass and increase in carnivorous zooplankton. However, this shift will result in decreased carrying capacity for future fish communities and less nutritious food, exacerbating projected declines in small pelagic fish biomass in tropical regions by 2100.

Summary: Competition and intraguild predation can affect predator diet. In this study, sympatric predators, the western quoll and the domestic cat, showed high dietary overlap. However, the quoll's broad and flexible diet, along with its high predation efficacy, appeared to assist in facilitating coexistence and reducing competition in this novel predator interaction.

Summary: This study examines the complex ontogenetic movements of groundfish species in terms of size, species, and geographic regions. The results show that small fish exhibit larger ontogenetic shifts in depth compared to larger fish, while the changes in latitude and longitude are relatively small. These findings suggest that size structure and ontogenetic shifts should be taken into account when studying population distribution.

Summary: Understanding the complex interplay among chronic environmental stressors, mass-mortality events, and population size structure sharpens our ability to manage and to restore coral-reef ecosystems in an increasingly disturbed future. Our study reveals that the impact of chronic stressors is amplified in highly disturbed environments, as disturbance weakens the buffering effect of space competition and size structure mediates the extent and pace of coral population recovery following a large-scale mortality event.

Summary: Research shows that food decline in the ocean can mitigate rather than exacerbate the negative effect of elevated migration costs imposed by infrastructure building in streams on fish. This counterintuitive effect results from the highly nonlinear manner in which these stressors interact and affect individual energetics.

Summary: PSPManalysis is a software package that simulates ecological dynamics, computes ecological steady states, and detects bifurcation points in dynamics. It also allows for analyzing evolutionary dynamics and singular states of PSPMs, providing a more comprehensive and in-depth approach to studying the impact of environmental conditions on individuals' life history.

Summary: The study shows that the impact of fishing for forage fish on piscivores depends on the fishing mortality of the piscivores. When the fishing mortality of piscivores is high, fishing for forage fish benefits the piscivores, but when fishing mortality of piscivores is low, overfishing of forage fish can lead to declines in piscivore biomass.

Summary: Ecologists have sought to understand how environmental variation affects natural populations by using transfer functions and continuous-time models to analyze resonant characteristics of size-structured populations, particularly in the case of stony corals. The analysis reveals a multi-decade resonance driven by space competition between coral colonies, with resonant oscillations most strongly determined by colony growth rate and potential for resonance greatest when colony growth is weakly density-dependent.

Summary: The study shows that incorporating differences in vulnerability to predation and foraging efficiency between juvenile and adult individuals can result in larger and more complex communities in model simulations. These diverse communities are stable or fluctuate with limited amplitude, even with a highly connected population-level interaction network. This suggests that differences between juveniles and adults may have a significant impact on the stability of natural communities.
