Summary: This study shows that selection can enhance starvation and cold tolerance in fruit flies, but starvation tolerance negatively impacts cold tolerance. Additionally, selection for starvation or cold tolerance also affects larval development time, longevity, and copulation duration in fruit flies.

Summary: This study explores the trade-offs among fungal traits, revealing a negative relationship between maximum growth rate and traits related to resource capture, as well as distinct life history strategies. Additionally, it identifies a negative relationship between extracellular enzymes and chitosanase, forming a different life history strategy.

Summary: The study focused on the physiological and morphological responses of insects to extreme and rising mean temperatures caused by climate change. It revealed shared physiological and morphological responses to temperature and desiccation, with potential conflicts between the need to regulate heat and water balance. The research also highlighted the sensitivity of a large species such as Geotrupes stercorarius to warm and arid conditions with potential implications for its geographic distribution and the provisioning of ecosystem services under a climate change scenario.

Summary: Life-history theory predicts energy allocation trade-offs between traits when resources are limited. This study evaluated growth versus reproduction trade-offs in female bighorn sheep and mountain goats, finding that growth traits can accurately predict reproductive history. The predictive models based on annual growth could assist conservation and management in a broad range of species.

Summary: This study on wild chacma baboons identifies two optimal birth timings in their annual cycle, maximizing offspring survival or minimizing maternal interbirth intervals. Observed births are most frequent between these optima, suggesting an adaptive trade-off between current and future reproduction.

Summary: Phenotypic trade-offs are common in nature, but the mechanisms driving them are not well understood. Research shows that all animals have evolved mechanisms to acquire oxygen and contract muscle, sometimes at the expense of other activities or traits. Convergent pathways have also evolved to deal with environmental challenges. Whole-animal performance traits, such as locomotion, are important for survival but can come at a cost to other aspects of the phenotype. Understanding the mechanisms behind these trade-offs will help explain phenotypic variation at an evolutionary scale.

Summary: Most marine organisms have complex life histories, where the individual stages of a life cycle are often morphologically and ecologically distinct. The degree to which genetic and phenotypic links among stages hamper adaptation in any one stage remains unclear. This study explores the impact of carry-over effects and genetic links on fitness trade-offs between different life-history stages, and finds that evolutionary conflicts among stages can be ameliorated by carry-over effects. The results suggest that organisms with complex life histories may face greater constraints in adapting to global change.

Summary: Host-parasite coevolution can drive genetic diversity by trading off traits used in arms races and traits used in resource competition. In a laboratory experiment with bacteriophage lambda and Escherichia coli, multiple positive trait correlations were found but few canonical trade-offs were observed. The study suggests that coevolution can promote genetic diversity in more complex ways than previously thought.

Summary: This study examines the demographic trade-offs in forest dynamics, particularly the impacts of conspecific negative density dependence (CNDD) on growth and survival. The results suggest that density dependence and environmental filtering are key factors influencing individual growth-survival trade-offs. Additionally, CNDD plays a role in shaping these trade-offs at the community level. Shade-tolerance, mycorrhizal type, and life-stage of forest species respond differently to CNDD, providing insights into different community assembly mechanisms and their interactions.

Summary: The study revealed that the association between personality and life history is favored in some ecological contexts but not in others. In a predator-poor environment, more explorative sharks in semi-captivity were found to take more risks in the wild and grew faster. While in a predator-rich environment, despite selection for fast growth, no link was found between exploration personality and the growth-mortality trade-off.

Summary: We review the potential of the metabolome to enhance trait-based ecology and improve our understanding of plant and ecosystem functioning. We explore the relationship between the metabolome and plant functional traits, discuss life-history trade-offs and plasticity in shaping fitness, and propose solutions to challenges in acquiring and interpreting metabolome data. The Special Feature studies examine mechanisms behind plant community assembly, plant-organismal interactions, and effects of plants and soil microorganisms on ecosystem processes.
