Summary: The study found that in a condition of conditional cooperation, female blue tits invested more in caring for nestlings under cold conditions without affecting visit rates. Additionally, females showed higher levels of turn taking in the more demanding cold conditions, while males did not adjust their visit rates, indicating that turn taking was not restricted by other sex-specific tasks and did not lead to greater investment by male partners.

Summary: To optimize the production of cultivated resources, a mathematical programming model is formulated to determine the optimal location and sizing of growth facilities, considering the impact of growth time on resource survival rate. The method provides strategic information on facility number, location, and sizing, as well as operational decisions for optimal growth time to minimize costs. The facility location and sizing problem is solved using a two-stage algorithm and a linear mixed-integer solver in the context of large-scale coral aquaculture for reef restoration. Computational analysis explores the sensitivity of facility number, location, and sizing to changes in demand distribution and cost parameters, highlighting the importance of the relationship between growth time and survival in optimizing operational decisions.

Summary: Parents often optimize their investment in each breeding attempt to maximize fitness. In this study, researchers tested the hypothesis that coordination among carers reduces the time a brood's location is advertised to predators. However, the results did not support the prediction that carers adjust coordination behavior in response to predation risk.

Summary: This study introduces two new benchmark datasets, Food101-LT and VFN-LT, for addressing the class imbalance issue in food classification. A novel two-phase framework is proposed to improve the performance of food classification by undersampling the head classes and oversampling the tail classes. The proposed method achieves the best performance on both datasets and demonstrates its potential for real-life applications.

Summary: European grayling is an endangered salmonid fish species with decreasing populations in European waters. This study analyzed the reproductive parameters of grayling females in a hatchery, including fecundity, egg size, and embryo survival. The results showed significant differences between first time spawners and repeat spawners, with repeat spawners producing more eggs. Absolute fecundity was correlated with the total length and weight of grayling females, while relative fecundity was not. Heavier eggs had a higher rate of survival, particularly for first time spawners. This suggests that larger and older grayling females should be prioritized for hatchery reproduction.

Summary: This study used a trait-based approach to investigate the population responses of soil-dwelling Collembola species to extreme heat events. The results showed that while resistance remained consistent across species, the recovery response of the most heat-sensitive species was strongly affected. The detrimental effects of heat on fecundity were found to be responsible for changes in the body size distribution of recovering populations.

Summary: The study found that hybridization of Oreochromis karongae, Oreochromis shiranus, and Oreochromis mossambicus resulted in higher number of eggs and relative fecundity, but egg size, hatching period, hatchability, and hatchling survival were species specific. There were no significant differences between interspecific and pure crosses of the same species in terms of reproductive performance, except for a higher number of female spawned in interspecific crosses of female O. karongae.

Summary: Soil contamination by hydrocarbons has negative effects on population health and welfare, especially in urban environments. The response of Orthonychiurus folsomi, a springtail species, to diesel contamination was studied. It was found that diesel has negative effects on various population parameters, with the most significant effects observed at concentrations above 500 mg/kg. Therefore, O. folsomi could be a useful bioindicator for detecting diesel-contaminated soil.

Summary: The long-tailed goral is a critically endangered herbivore in South Korea, vulnerable to heavy snowfall as seen in the deaths of 24 animals in 2010. The study suggests that the dead gorals were predominantly pregnant females or young, who may have been unable to escape due to lower mobility. Optimal goral habitats should be considered for rescue and artificial feeding during climate catastrophes.

Summary: This paper proposes a method to address the long-tailed data distribution problem by preserving specific capacity for low-frequency classes in the parameter space. Instead of using different branches for different classes, the authors design an effective residual fusion mechanism to enhance the recognition of medium+tail and tail classes. Experimental results demonstrate the effectiveness of this method.

Summary: In the Iterated Prisoner's dilemma, fixed partner interaction leads to behavioral self-organization, while shuffled partners generate subgroups of memory-one strategies that block the self-selection process. Furthermore, longer treatments are needed to accurately capture the learning phase participants go through.

Summary: Local adaptation is an important evolutionary process that allows populations to adapt to their local environment. This study experimentally evolved rotifer populations under either unidimensional or multidimensional divergent selection. The results showed that populations exposed to multidimensional selection initially increased in local adaptation but later declined, while populations exposed to unidimensional selection had a slower but eventually stronger increase in local adaptation.

Summary: The study found that the evolution of traplining in hummingbirds involves morphological specialization through the coevolution of longer bills with long-tubed flowers. It was previously believed that this specialization was irreversible and an evolutionary dead end, but the study discovered multiple independent transitions to traplining and suggested that it does not lead to lower rates of diversification.

Summary: In species with biparental and cooperative brood care, coordination of provisioning visits plays an important role in resolving conflicts among carers and ensuring collective investment in raising a shared brood. This study of long-tailed tits reveals that active coordination takes the form of turn-taking or synchrony, and varies among individuals and nests. The findings suggest that the degree of coordination is socially plastic and depends on reproductive status and the number of carers.

Summary: Alloparental care in cooperatively breeding species can affect breeder survival and reproduction, and the helping behavior may change with age. This study on long-tailed tits found that the presence of helpers increased reproductive success and offspring recruitment, but age did not affect survival. No evidence of significant senescence was found, although individuals had lower inclusive fitness in their last year of life. Lifetime reproductive success was related to reproductive life span and body mass. Helping decisions were driven by individual condition, and immigrant fitness was predicted by body mass.

Summary: We used six years of detailed life-history data from a population of riflemen to estimate vital rates and understand their contribution to the population decline. Juvenile and adult survival rates were low compared to other populations, while breeding success was high. A population matrix model confirmed a negative trend, with reduced recruitment being the main factor contributing to the decline. More data from populations with stable or positive trends would be helpful for understanding the factors affecting vital rates.

Summary: Studies on the effects of elevation and habitat changes on biodiversity have a long history and have gained renewed interest in recent years. Mountainous regions, especially, are important for their unique species and relative lack of human impact. The drastic temperature decrease with increasing elevation in tropical regions has led to increased research, given that global warming could negatively impact tropical forest species.

Summary: When multiple carers invest in a shared brood, there is often conflict over investment which leads to suboptimal outcomes. Conditional cooperation, such as turn taking or alternation, has been proposed as a solution to this conflict. This study examines how carers behave in a context-dependent manner to increase the level of alternation using observations of provisioning in the long-tailed tit. The results show how alternation and synchrony arise in this species, revealing the mechanisms behind coordination of care.

Summary: Habitat selection has significant impacts on individual fitness. The natal habitat preference induction (NHPI) hypothesis proposes that individuals choose habitats that resemble the environment they experienced in early life. This study examined and tested the NHPI hypothesis in monk parakeets, an invasive species that nests primarily in pine or palm trees. The results showed that dispersed individuals and adult birds undertaking breeding dispersal preferred to nest in their natal tree type, demonstrating the influence of early life experiences on habitat selection.

Summary: Behavioral compatibility and personality traits play an important role in the re-pairing patterns of black-legged kittiwakes. Pairs with dissimilar boldness levels are more likely to experience breeding failure and re-pair the following year. However, there is no evidence that re-pairing affects reproductive success in the subsequent season.
