Ongoing anthropogenic change is altering the planet at an unprecedented rate, threatening biodiversity, and ecosystem functioning. Species are responding to abiotic pressures both individual population levels, with changes affecting trophic interactions through consumptive pathways. Collectively, these impacts alter goods services that natural ecosystems will provide society, as well persistence of all species. Here, we describe physiological behavioral responses species global on levels result in detectable diet across terrestrial marine ecosystems. We illustrate shifts dynamics food webs implications for animal communities. Additionally, highlight myriad tools available researchers investigate consumption patterns interactions, arguing data a crucial component ecological studies change. suggest holistic approach integrating complexities choice environmental drivers may be more robust resolving trends predicting web responses, potentially identifying early warning signs diversity loss. Ultimately, despite growing body long-term datasets, there remains dearth ecology temporal scales, shortcoming must resolved elucidate vulnerabilities changing biophysical conditions.

ABSTRACT Mutualistic species often must survive periods of their development without mutualist partner, but we lack a clear understanding the ecological mechanisms that maintain mutualisms despite these gaps in partnership. In ant‐plant protection mutualisms, plants house ant colonies deter herbivores. Yet juvenile ant‐plants symbiotic and withstand herbivory pressure until they are colonized by ants. A sapling's ability to host ants or employ alternative direct defenses, such as leaf secondary metabolites, may depend on access key resources, like light, soil nutrients, water. Alternatively, receive biotic at little resource cost from generalist predators, spiders. We examined whether Cecropia trees maintained sapling chemical defenses were associated with resources. surveyed three naturally occurring across rainfall gradient northwest Costa Rica. found both defense regulated availability fertility, water saplings. Rather than trade off, larger saplings more resources likely invest strategies, whereas smaller fewer appeared have defense. also although spiders common resource‐poor, undefended saplings, did not reduce herbivory. This study highlights importance determining performance during early ontogenetic stages.

ABSTRACT Aim Introduced species can establish in climates outside of their native niche and undergo ‘niche shifts’. However, studies shifts generally rely on above‐ground climate data, neglecting the potential buffering effect ground‐level or soil climates. Location Global. Time Period Present. Major Taxa Studied Formicidae. Methods Here, we investigated impact temperatures 95 introduced ant using both ordination hypervolume‐based approaches. We compared air temperature temperature. Results Overall, between 65.2% 82% (depending metric) exhibited smaller when considering temperature, with varying levels correlation air‐ soil‐temperature across (Correlation coefficient range: 0.56–0.73). Furthermore, conditions were more uncoupled than expected at random. This suggests that use microrefugia this may explain lower observed microclimatic conditions. Ecological traits, nesting type, forest cover spatial spread did not consistently differences metrics among species. highlights need for experimental research to explore versus ground‐climatic shifts. Main Conclusions overall highlight importance incorporating ecologically relevant particularly small, ground‐dwelling organisms like ants. study emphasises ongoing a nuanced understanding intricate interplay context dynamics. Ultimately, soil‐level datasets improve habitat suitability models, leading accurate predictions establishment success

Abstract Land use changes can alter resource availability and microclimate variables in tropical ecosystems, generally altering community structure by decreasing species richness changing its composition. These affect foraging activity, nutrient preferences consequently ecosystem functions. Our aim was to assess how activity preference are influenced land microclimate. We sampled ants (Formicidae) at 32 sites undergoing conversion from natural habitats coffee systems two Neotropical biomes: the Atlantic rainforest Cerrado. assessed (amino acids, carbohydrates, lipids sodium) predation using mealworm larvae, while also measuring temperature humidity. found same foraged for different resources, likely because generalist perform these activities on ground. Furthermore, energetic resources (carbohydrates lipids) positively correlated with larvae. This indicates that limitation of contribute an increase predatory activity. Moreover, ant amino acids decreases increasing temperature, indicating prefer consume support metabolic processes. In conclusion, is primarily carried out species. addition, nutrients, driven limitations, linked increases rising temperatures decrease acids. Thus, conserving mitigating may enhance larval insect function habitats.
