Summary: Our research demonstrates that the interplay between competition, birth-death dynamics, and spatial constraints can lead to a nonmonotonic relationship between ecological majority-minority switching and diffusion between patches. This suggests that diffusion can influence birth-death ratios and enhance the preservation of species.

Summary: Synchrony in species richness across patches in metacommunities is related to ecosystem stability, and can be driven by environmental stochasticity and dispersal, as well as influenced by community structure. Ecosystem stability is more strongly linked to richness synchrony than species richness itself.

Summary: This study investigates the geographic patterns of spatial synchrony in fish populations and the drivers behind it using long-term ecological research data from the Upper Parana River floodplain. The study finds positive spatial synchrony for most species but at relatively low levels. It also highlights the complex spatial patterns in synchrony through modular structures in species networks. The study emphasizes the need for monitoring multiple sites and managing key sites to increase metapopulation stability.

Summary: The study investigates how dispersal affects population variability and spatial synchrony at different timescales, showing that the effects of dispersal on populations are opposite between short and long timescales. The impact of dispersal differs for populations with different recovery mechanisms, with implications for empirical studies.

Summary: This study found that drought can decrease the stability of invertebrate metapopulations by filtering out poorly adapted species locally and synchronizing their dynamics across a river network. Among metapopulations, species with resistance and resilience traits remained stable while species vulnerable to drought faced an exponentially increasing risk of quasi-extinction as flowing habitats contracted within the river network.

Summary: This study demonstrates that fishing activities can initially promote individual growth but also potentially heighten the sensitivity of populations to environmental change. Fishing-induced release of density controls benefits individual growth across different fish species, and environmental factors can also have additional effects on growth rates.

Summary: Temporal variability in ecological structure and processes tends to decrease with increasing spatial scales and levels of biological organization. However, the patterns and mechanisms of variability across trophic levels remain poorly understood. In this study, we analyzed abundance time series data from spatially structured communities and found that temporal variability in abundance decreases from producers to tertiary consumers, mainly at the local scale. Synchrony within sites increases with trophic level, while synchrony among communities decreases.

Summary: Spatial synchrony levels vary between freshwater fish species in a fragmented river. Reproductive traits have a strong influence on spatial synchrony, while more plastic traits, such as diet and habitat preferences, are poor predictors of spatial synchrony.

Summary: During the Safer at Home period in March-April 2020, there was a significant decrease in the number of breath tests conducted and collisions involving DUI in Los Angeles County. Taking into account traffic volume, the odds of encountering an intoxicated driver decreased by approximately 23%.

Summary: Competition from invasive species is posing an increasing threat to biodiversity. In Southern California, the western gray squirrel is facing competition from the fox squirrel. The study found a correlation between temperature and the population numbers of both species, with the weaker competitor facing a higher risk of extinction as environmental fluctuations shift to long timescales. Additionally, significant shifts in timescales of environmental fluctuations have occurred in the past two decades.
