Summary: This study found that container Aedes mosquitoes exhibit different skip-oviposition behaviors under different oviposition media and environmental conditions, which are influenced by oviposition site conditions. This behavior has important implications for the application of autodissemination trap technology.

Summary: Maintaining a central refuge such as a nest or burrow can provide protection but limit the ability to disperse. Long-lived ant colonies that build large nests are susceptible to changing environmental conditions. The Australian meat ant population exhibited a surge in nest production during drought, allowing colonies to relocate to more favorable areas. This strategy may be important for central place foragers to track preferred conditions in the face of climate change.

Summary: Microbes in the wild adapt to changing environments by using sensory regulatory systems and gene expression noise, and recent experimental results show that phenotype-switching rates may systematically decrease with growth rate. This growth rate dependent stability (GRDS) can overcome the trade-off that limits bet-hedging, allowing for effective adaptation even when environments are diverse and change rapidly.

Summary: The phase variation mechanism of Burkholderia thailandensis can enable population heterogeneity through genomic rearrangements, allowing the bacteria to adapt to environmental fluctuations. The presence of duplicate DNA regions with varied copy numbers provides selective advantages for growth in different conditions, expanding the species' ecological repertoire.

Summary: A comparative imaging and transcriptome analysis was conducted to investigate morph-specific developmental differences in Aethionema arabicum, a Brassicaceae model for diaspore dimorphism, revealing two distinct morphologies in seed coat development with mucilaginous and non-mucilaginous diaspores. The research highlights the importance of studying epidermal cell differentiation and mucilage biosynthesis control mechanisms using Ae. arabicum as a model system.

Summary: Research suggests that animals adjust their evolutionary search efforts for resources based on the cost of information acquisition, cost of competition, and distribution of resource qualities. Results show that with lower information acquisition costs, stable search efforts increase with a higher proportion of low-quality resources, while the opposite is true with higher information acquisition costs. Additionally, costly information acquisition may explain why the ideal free distribution model is not always found in empirical studies.

Summary: The sandpaper frog, Lechriodus fletcheri, is a temperate frog species that usually reproduces only once in its one-year lifespan. However, the species oviposits in ephemeral pools with a high risk of reproductive failure due to unpredictability and short hydroperiods. Research suggests that both males and females of L. fletcheri have the ability to participate in multiple reproductive events within a season, indicating that they may be abbreviated iteroparous rather than truly semelparous. This finding provides evidence that short-lived anurans may utilize alternative bet-hedging strategies similar to multi-year iteroparity.

Summary: Density-dependent behavioral interactions can facilitate invasion success and subsequent population expansion of non-native species. Sticklebacks dominate behaviorally over shrimp, but shrimp's activities and distribution are influenced by stickleback density.

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: The research found that in optimal annual plant models in temporally variable environments, increasing individual lifetime correlation leads to earlier maturity time. Different production functions affect the choice of optimal schedules, with a period of mixed growth and reproduction for intermediate ranges.

Summary: When predators consume prey, they are at risk of being infected with the parasites of their prey, which can then affect the predator's immune system and natural selection. This study highlights the interplay between multivariate trait evolution and the dynamics of ecological communities, showing that ecological morphology influences immunity evolution, and vice versa, with fundamental asymmetries.

Summary: The phenomenon of masting plays a crucial role in the evolution of scatter-hoarding, as it reduces seed pilferage and lowers the reproductive cost of caching, promoting the evolution of scatter-hoarding behavior.

Summary: The paper investigates the classification problem of stochastic models of interacting species and proves a variant of Palis' conjecture. The long-term statistical behavior is determined by a finite number of stationary distributions, and there are three general types of behavior that could occur. The classification problem can be simplified by computing Lyapunov exponents. This research provides a rigorous foundation for ecology's modern coexistence theory.

Summary: Contemporary studies of species coexistence are often based on deterministic models that do not accurately reflect the complexities found in nature. This study used experimental field data to test the efficacy of deterministic coexistence metrics on the duration of species coexistence in a finite world. The results highlight the importance of integrating information on both invasion growth rates and species' equilibrium population sizes in understanding the variation in species coexistence times.

Summary: To understand species coexistence, ecologists study invasion growth rates, which determine if species can recover from being rare and therefore coexist. This study proves theorems that determine when the signs of invasion growth rates determine coexistence, and which invasion growth rates need to be positive. The results highlight the importance of using concepts about community assembly to study coexistence.

Summary: Growing evidence suggests that temporally fluctuating environments play a crucial role in maintaining variation within and between species. However, studies of genetic variation within populations have been primarily conducted by evolutionary biologists, while population and community ecologists have focused more on species diversity. This article reviews theoretical and empirical studies in population genetics and community ecology, exploring the connection between the "temporal storage effect" and diversity maintenance. By comparing and synthesizing ecological and evolutionary approaches, the authors aim to enhance our understanding of diversity maintenance in nature.

Summary: The relative arrival time of species can influence their interactions and determine which species can persist in a community. The differences in stages of interacting species can generate priority effects, altering the outcomes between exclusion, coexistence, and positive frequency dependence. However, these priority effects are strongest in systems with few generations per season and weaken in systems with many overlapping generations.

Summary: This study re-examines the interaction patterns among species primarily regulated by a common predator. The P* rule, which states that the prey species supporting the highest mean predator density will exclude other prey species, is proposed. The results show that when the temporal auto-correlations in predator attack rates are positive but not too strong, the prey species can coexist.

Summary: Stochastic discrete-time susceptible-infected-susceptible (SIS) and susceptible-infected-recovered (SIR) models of endemic diseases are introduced and analyzed. The basic reproductive number R-0 determines the global dynamics of the models. In deterministic models, the infection persists if R-0 is greater than 1, while in stochastic models, the infection goes extinct in finite time with a probability of 1 for all R-0 values.
