Summary: The dominant species in intercropping may be cultivated at a higher density to achieve greater yield, but increasing their density does not always lead to improved yield in intercropping. Land equivalent ratios were higher in the dry year compared to the wet year, suggesting that intercropping performs better under conditions with limited resources.

Summary: Insects hosting vertically transmitted microbes exhibit variation in symbiont density which can have effects on survival and protection against pathogens. Different genotypes of aphids show varying responses to symbiont density, indicating a complex relationship between hosts and microbes. Antagonistic coevolutionary interactions may play a role in maintaining standing variation in symbiont density in natural populations.

Summary: The study found that even in the absence of initial genetic diversity and recombination, small populations can rapidly exhibit adaptive genetic changes, indicating that de novo genetic variation or alternative sources of phenotypic variation may help in the establishment and persistence of low-diversity populations.

Summary: The study investigated the behavioral patterns of Penaeus japonicus and how they are influenced by the natural farming environment. The results showed that light intensity and population density were the most influential factors in shrimp behavior. Female shrimp exhibited less aggression and more adventure compared to male shrimp. These findings provide valuable insights for shrimp farming management strategies.

Summary: This study examined the relationship between willingness to participate in Ecological Momentary Assessment (EMA) research and respondent characteristics, and identified the most critical predictors of participation. The results suggest that migration background is the most promising target for improving EMA participation and sample representativeness, but further research is needed to improve the prediction of participation in EMA studies in health.

Summary: Predicted global temperature changes are expected to increase extinction risk for ectotherms due to increased metabolic rates. Plastic metabolic responses to seasonal thermal cues were observed in some populations, but limited plastic responses were found for future climate temperatures. Warming is likely to impact the energy budgets of salamanders, potentially affecting individual growth and reproductive investment.

Summary: As global climate change alters the distribution range of macroalgae, it is necessary to assess its impact on species range shifts for conservation purposes. In this study, we investigated the geographical variation and physiological responses of Sargassum thunbergii populations to climate change. The results indicate that there is intraspecific variability in the response of populations, with the southern group showing higher resilience and adaptability to changing temperatures.

Summary: In trait-based ecology, it is common to use measures to quantify phenotypic variation between populations. However, these measures overlook the within-population trait variability and some of them cannot be partitioned between populations. This study proposes a new measure called the phenotypic dissimilarity (PhD) index to address these issues and provide a tool for quantifying phenotypic variation within and between species.

Summary: This study found evidence of sex reversal in the viviparous reptile Carinascincus ocellatus, and showed that the frequency of sex reversal is related to temperature. The study also suggests that XX-biased genotypic sex ratios could produce either male- or female-biased phenotypic sex ratios, depending on the rate of XX sex reversal.

Summary: Our study involved collecting terrestrial isopods and termites in the Brazilian Atlantic forest, sequencing and identifying Wolbachia strains in these groups, and constructing phylogenies that showed significant jumps of Wolbachia between terrestrial isopods and termites despite their phylogenetic distance, suggesting likely horizontal transmission of supergroup F Wolbachia between the two species. Our findings contribute to understanding the success and distribution of this symbiont.

Summary: Cryptic species pose a challenge for morphologically based species identification, but molecular approaches can provide valuable taxonomic hypotheses. Research on South American freshwater crabs of the genus Aegla suggests that morphological similarity does not always indicate genetic relatedness, and there may be cryptic species present. The diversity of these crustaceans seems to be influenced by factors such as habitat fragmentation, morphological stasis, and recent divergence.

Summary: Crustaceans are well-known for their ability to autotomize and regenerate appendages, particularly their specialized claws. However, regenerated claws tend to be weaker than original claws in terms of pinching strength and muscle mass. This suggests that claw regeneration may be the mechanism behind the production of dishonest claws in crayfish.

Summary: In this study, the authors examined the allometry of contest-related traits in the Amazonian tusked harvestman. They found that the allometry of threat devices and weapons used in contests was consistent with the functional allometry hypothesis. However, they also discovered that function alone could not explain allometric differences in homologous traits between males and females. Additionally, function could not explain differences in allometric slopes between male morphs. The study suggests that further research is needed to understand the factors that affect the allometric slopes of male-dimorphic traits.

Summary: In many species, males possess specialized weaponry that confers benefits during male-male combat. However, females often only have reduced versions of male weaponry. This study focuses on the size, performance, and biomechanics of hindlegs in Thasus neocalifornicus. The findings suggest that selection on the performance and biomechanics of sexually selected weapons can influence the expression of sexual dimorphism.

Summary: Birds are a remarkable example of how sexual selection can produce diverse ornaments and behaviors. Unlike other animals, birds have a scarcity of weapons, and this study suggests that the costly mode of locomotion-powered flight in birds may help explain this. The simulation and analysis showed that species with flight-efficient wings tend to have fewer or no bony spurs, and this association likely arises from more frequent evolutionary loss of spurs due to increased flying. This suggests that the absence of weaponry may be another feature of the avian body plan that allows birds to efficiently explore the aerial habitat.

Summary: In species that compete for resources, individuals use specialized structures as weapons to gain a mechanical advantage. This study examines the impact of weapons on contest outcomes and identifies patterns in how animals use their weapons. The results show that the extent to which weapons influence contest success depends on weapon traits and fighting style. The study highlights the need to consider weapon function and a wider diversity of species when studying animal weapons.

Summary: This study investigated how environmental temperature seasonality affects the seasonal variation in body temperature and preferred body temperature in lizards. The results showed that body temperature varied more than preferred body temperature across seasons. Body size and thermoregulatory strategy influenced the variation in body temperature. Additionally, an increase in environmental temperature seasonality led to an increase in the seasonal variation of preferred body temperature. The study also found significant differences in body temperature and preferred body temperature among lizard families.

Summary: This study describes the population structure of Tallitroides topitotum in terms of morphometric and reproductive aspects. The research findings show a significant correlation between body and head lengths, as well as body and marsupium lengths in ovigerous females. However, there is no correlation between morphometric data and female fertility. Additionally, there is a positive correlation between the size of individuals and the latitude of occurrence, although not significant.
