Summary: This study investigated the coexistence of four closely related Lactobacillus species in the honey bee gut, revealing that they can stably coexist in the presence of pollen but not in simple sugars. Metatranscriptomics and metabolomics showed that the species utilize different carbohydrate substrates from pollen, indicating resource partitioning as the basis of their coexistence. Overall, this research provides insights into bacterial interactions and coexistence in the gut environment.

Summary: Seasons impose different selection pressures on organisms, leading to varying adaptive strategies. This study investigates the resolution of seasonal conflicts in two closely related butterfly species through field experiments, laboratory work, and citizen science data analyses. The results reveal differences in fitness and population dynamics between Pieris rapae and P. napi across seasons, driven by physiological and behavioral traits. P. rapae maximizes gains during growth seasons but suffers from higher winter mortality, while P. napi minimizes harm during adverse seasons.

Summary: The study found that the pattern of surface colonization by swarming mixtures is influenced by kin types, with closely related strains colonizing together and less related strains showing competitive exclusion. The outcome of nonkin swarm expansion depends on the initial ratio of competing strains, and the addition of surfactin can complement the swarming defect of nonkin mutants. Close encounters in nonkin mixtures lead to territorial exclusion, limiting the exploitation of surfactin by nonkin nonproducers.

Summary: This study assesses the competitive interactions among larvae of three co-existing species of caddisflies. The researchers found that the competitive interactions were usually decided by body size and mandible features. More than half of the interspecific conflicts ended with a draw, and 80% of intraspecific interactions had a decisive outcome. H. pellucidula was the most successful species in fights between species, while H. modesta was the weakest.

Summary: The aim of this study was to use high-throughput sequencing techniques to investigate the taxonomy of Actinomyces naeslundii and its closely related species. The strains were classified as A. naeslundii and A. oris based on MLST data analysis. Whole genome sequencing was performed on selected strains of A. oris and A. naeslundii, and comparative genomic analysis was carried out. The results showed that A. oris forms six distinct groups, while A. naeslundii forms three. The correct designation of isolates will help in the identification of clinical Actinomyces isolates found in dental plaque and accelerate further research on the biochemical characterization and pathogenesis of this group of microorganisms.

Summary: This paper analyzes the development trend of the marine supply chain in response to emission reduction pressure and supply chain changes, considering the impact of the government's carbon tax policy. The study finds that carriers are inclined to build alliances and compete with ports for leadership. By redesigning subsidy and revenue-sharing contracts, conflicting interests can be resolved. The paper provides new incentives for companies to integrate cooperation.

Summary: The study found that the tail of deer mice affects body roll during arboreal locomotion, with different tail lengths resulting in differences in body rotation from tail motions. The shape of caudal vertebrae influences the curvature angle of the tail. Although forest and prairie mice have differences in caudal vertebrae length and number, this does not appear to be due to a functional trade-off related to tail curvature.

Summary: By studying the oldfield mouse, researchers have identified the genetic basis of color variation in their dorsal coats. A specific region upstream of the Agouti signaling protein coding region was strongly associated with pigment variation. The study also found that the light allele of this region has been maintained in mainland populations and has spread to and been selected in independent beach mouse lineages, facilitating their rapid and parallel evolution.

Summary: This study characterized the genetic basis of trait variation in different ecotypes of deer mice and identified a chromosomal inversion linked to tail length and coat color. The frequency of the inversion was high in the forest ecotype, decreased across a habitat transition, and was absent in the prairie ecotype. Divergent selection was implicated in maintaining the inversion at observed frequencies despite high levels of gene flow, and the study explored the fitness benefits arising from suppressed recombination within the inversion.

Summary: Animals vary in their behavioral flexibility depending on social context. By comparing three species of deer mice, researchers found that mice living in monogamous societies were more likely to cooperate in digging longer burrows. Additionally, opposite-sex pairs were more socially cohesive and efficient digging partners than same-sex pairs.

Summary: Parental behaviors vary among species in terms of magnitude, onset relative to reproduction, and sexual dimorphism. In deer mice, promiscuous species show low paternal care, while monogamous species exhibit biparental care. The timing of parental behaviors also differs, with some species showing behaviors before mating and others only after giving birth. These patterns align with the socioecology of the species.

Summary: It has been found that cries play an important role in parental care during the early stages of neonatal development in deer mice, while ultrasonic vocalizations (USVs) play a role in later stages. By comparing the vocalization characteristics of different species and laboratory mice, it was found that even within the same species, there are differences in vocalization features among different populations. Through genetic cross experiments, it was found that vocalization features are genetically controlled, with different degrees of genetic dominance for different features.

Summary: The genomic landscape of transposable elements in deer mice is different from that of other mammals, with long terminal repeat elements being more common than long interspersed nuclear element retrotransposons. Deer mouse endogenous retroviruses exhibit diverse origins and have impacted the evolutionary trajectory of LINEs. The expansion of Kruppel-associated box domain-containing zinc finger genes, likely controlled by ectopic recombination between ERVs, is also observed in the deer mouse genome.
