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: This study examined the impact of extrinsic competition on host utilization and coexistence between two parasitoid species. The results showed that egg mass size was an important predictor of extrinsic competition, and reproductive traits of the parasitoid species contributed to their competitive advantage in different-sized egg masses. This study highlights the importance of considering extrinsic competitive interactions between parasitoid species in biological pest control.

Summary: Theory predicts that species can only coexist if they have sufficient differences in resource and/or microhabitat utilization. In hermit crabs, fitness is mainly limited by shell availability. This study found significant overlap in shell use and microhabitat occupation between two hermit crab species, suggesting a potential trade-off between resource exploitation and interference.

Summary: This study conducted field experiments in three lakes to manipulate the relative frequencies of two damselfly species and evaluate the demographic contributions of different mechanisms affecting population growth. The results showed that interactions between mechanisms and life stages varied among populations, indicating that local coexistence is population specific. Furthermore, the study found that multiple mechanisms do not always increase competitor coexistence, as they can also lead to exclusion. Therefore, identifying coexistence mechanisms in other systems requires considering the contributions of different fitness components across the life cycle.

Summary: The effectiveness of entomopathogenic nematodes (EPNs) for managing insect pests can vary depending on the combination of species used. Differences in dispersal rates between conspecific and heterospecific EPN species may contribute to these varying outcomes. Our study found that the dispersal rates of different EPN species were significantly different, independent of body mass or foraging strategy. Additionally, interspecific communication between EPNs appeared to affect both orientation and dispersal rates, potentially impacting their effectiveness for biological control and overall fitness.

Summary: In this study, the competitive mechanism underlying the displacement of Bursaphelenchus mucronatus by Bursaphelenchus xylophilus during interspecific competition was investigated. The results showed that in the early stage of competition, the population of both species increased significantly, but the abundance rates were different - B. xylophilus increased while B. mucronatus decreased. Unexpectedly, the sex ratio of females to males in both species sharply increased and peaked, indicating that female dominance plays a crucial role in interspecific competition. Furthermore, mating behaviors revealed that mating success rate dropped significantly when two or more males or females of the other species were introduced, suggesting that mating disruption contributes to the displacement. These findings provide important insights into the competitive dynamics between these nematode species and highlight the significance of sex ratio and mating disruption in interspecific competition.

Summary: Negative interspecific mating interactions can impede species coexistence, while conspecific sperm precedence (CSP) may help mitigate the costs of interspecific mating and hybridization. Experimental and mathematical modeling studies suggest that species exhibiting CSP may struggle to coexist in a local environment in the presence of reproductive interference.

Summary: This study explores the competition and coexistence patterns between different lineages of the influenza virus. The results demonstrate that lineages infecting the same host experience stronger competition compared to those infecting different hosts. Additionally, lineages with higher cross-region transmission intensity also face stronger competition and extinction pressures.

Summary: For many years, only one species of praying mantis in the genus Hierodula, Hierodula patellifera Serville, had been recorded in Japan. In recent years, however, a larger species, Hierodula chinensis Werner, has been discovered in Japan, and there may not be a sex pheromone-mediated reproductive interference between the two species.

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: 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: Mutualisms are important in maintaining biodiversity, but are not currently included in existing coexistence theory, leading to potential errors in assessing how mutualisms affect the coexistence of competing species. The author develops a theory predicting how multitrophic mutualisms mediate species coexistence and demonstrates the importance of considering mutualisms in evaluating coexistence consequences.

Summary: The type of diet readily available after adult eclosion does not significantly affect the future fecundity of adult ladybird beetles, as long as they find prey within a few days. High variability in pre-oviposition time was observed among females, and significant negative relationships were found between pre-oviposition time and both the number of eggs oviposited daily and the viability of egg batches.

Summary: The wood-feeding cockroach Panesthia angustipennis spadica displays gregarious behavior in decayed logs, with individuals aggregating regardless of kin relatedness. Laboratory experiments showed that both first- and second-instar nymphs exhibit gregariousness, suggesting that non-kin-based aggregation may help maintain colonies of this species containing individuals derived from multiple families in the wild.

Summary: The study investigates arthropod community-level diversity patterns along elevational transects on two different volcanoes of Hawai'i, finding that arthropod communities become increasingly distinct compositionally at higher elevations between the two transects. The results suggest that climatic differences play a crucial role in shaping beta-diversity patterns, with varying importance across taxonomic groups. Additionally, the correlation of climatic niche position between transects indicates that climatic filters influence colonization between adjacent volcanoes.

Summary: Many aphidophagous ladybird beetles lay clusters of eggs and sibling cannibalism occurs at hatching. The study found that developing eggs were larger than undeveloped sterile ones, and the hatchability of eggs was also associated with their size. This suggests that the production of relatively small sterile eggs serves as a circumstance-dependent maternal investment in improving the survival of first instar larvae.

Summary: This study used a nonlinear time series analysis to investigate the top-down and bottom-up effects between the citrus whitefly and the whitefly-specialist ladybird. The results showed a delayed positive effect of citrus whitefly abundance on ladybird abundance, but no significant causal effect of ladybird abundance on citrus whitefly abundance. Additionally, weather variables had minimal impact on the population dynamics of the two species. The findings suggest that bottom-up effects predominate in the weekly dynamics of this predator-prey system.

Summary: While most angiosperm plants have hermaphrodite flowers, a small percentage of dioecious angiosperms, including zoophilous species, require pollen transport from male plants to females. This study focuses on Eurya japonica, a dioecious, zoophilous plant that blooms in low-temperature seasons. The research finds that a diverse range of insects, particularly Diptera and Hymenoptera, play a crucial role in pollination and reproductive ecology of E. japonica, even at low temperatures. The presence of dipteran visitors positively correlates with higher fruiting rates and seed numbers.

Summary: The invasion of Roseau cane scale, native to East Asia, is causing dieback of common reed stands in the Mississippi River Delta, Louisiana. Previous research suggested that Common Reed Buntings and parasitoid wasps play a role in controlling the abundance of Roseau cane scale in its native range. However, little is known about other bird species that may prey on Roseau cane scale or their feeding patterns. This study used web search and citizen science data to identify bird predators and their feeding patterns in Japan.
