Summary: Individual behavior and local context play a crucial role in influencing the evolution of ecological interactions and network structure. Consumers can increase their fitness by actively choosing resources in trophic interactions, and mathematical modeling is often used to understand coevolutionary dynamics. Active consumer choice behavior is shown to be important in structuring interacting communities.

Summary: The structure of bat-plant networks in tropical forests is affected by precipitation levels, with higher precipitation leading to more modular and less nested networks. Contrary to expectations, drier conditions result in lower nestedness and higher modularity. The network structures are similar between El Nino and non-El Nino years in dry forests and rainforests.

Summary: Melastomataceae is a diverse family with species that have transitioned from specialized to generalized pollination systems. These transitions are associated with colonization of new habitats that have unpredictable or limited pollinators. In this study, the floral traits and visitors of two species in the Colombian Andes were examined to understand the generalization of their pollination systems. The breeding system of one of the species was also investigated. The results showed that flower and anther morphology, combined with nectar production, contribute to a generalist pollination system shared by the two species. This is the first report of a generalist pollination system in Miconia and Melastomataceae in the Andes, as well as the first report for species from specific sections in Colombia.

Summary: Climate change is a significant aspect of the current ecological landscape that impacts global and local environments. Researchers have progressed from basic descriptions of temporal changes to investigating the underlying causes, impacts, and consequences of these changes at both ecological and evolutionary scales. This era presents an exciting yet sometimes disheartening time for scientists.

Summary: This study provides the first comprehensive assessment of skewness in a bee community, and finds that both bee and flower phenologies tend to be right-skewed, with a more exaggerated asymmetry in bees. Early-season species tend to be the most skewed, and this relationship is also stronger in bees than in flowers. Differences in bee and flower skewness could account for up to 14% of pairwise overlap differences.

Summary: Encounters between flowers and invertebrates play a crucial role in tropical forest ecosystems. This study aims to provide a comprehensive database of flower-invertebrate interactions in the Atlantic Forest. The dataset includes over 18,000 interaction records forming 482 networks, involving 641 plant genera and 581 invertebrate genera. The study highlights the knowledge gap in canopy flower-invertebrate interactions and the need for further research in remote forested areas.

Summary: This study explores the effects of climate seasonality, plant and bat richness, morphological traits, and phylogenetic distance on the niche overlap of Neotropical bat-plant pollination networks. The results indicate that climate seasonality and bat evolutionary history are important drivers of niche overlap in these interactions.

Summary: Niche partitioning is crucial for species coexistence. However, the diel niche partitioning in mutualistic interactions has been overlooked. Through a study of a plant-hummingbird network in the Brazilian Atlantic forest, we found that diel partitioning was not observed for hummingbirds or plants. Instead, hummingbirds specialized in different plant species, suggesting trophic niche partitioning due to competition, while co-flowering plant species shared hummingbird visits during similar times, indicating facilitation. Our findings suggest that plants and hummingbirds have different strategies for promoting coexistence.

Summary: This study examined the relationship between fitness and interaction selectivity at both the species and individual level in 14 hummingbird-pollinated plant species in the Atlantic Forest. At the species level, there was no relationship between plant fitness and centrality or interaction selectivity, but there was a positive relationship between plant fitness and trait-matching between bill and corolla lengths. At the individual level, individuals with higher centrality values produced fewer seeds likely due to lower pollen deposition quality, while individuals with lower interaction selectivity produced more seeds probably due to higher conspecific pollen flow.

Summary: Recent reports of insect declines, attributed to anthropogenic land use intensification and climate change, have raised concerns among scientists and the public. This study provides evidence of long-term continuous declines in insect biomass and abundance in a protected subalpine meadow, which is embedded in an undisturbed natural landscape. The declines were correlated with changes in climate, specifically with less summer precipitation and winter snowfall, as well as warmer temperatures, suggesting that even relatively undisturbed habitats may not be immune to further insect declines.

Summary: Human activities threaten nature and ecosystem services, such as pollination. Ecological restoration provides opportunities for biodiversity conservation and sustainable agriculture. However, stakeholders' interactions and power access in social arenas are often overlooked in sustainable agriculture frameworks. This perspective integrates pollination services, ecological restoration, and public engagement for biodiversity conservation and agricultural production to enhance sustainable practices at different scales.

Summary: This paper investigates how landscape structure can influence coffee production at different scales, and evaluates the predictive utility of landscape metrics. The study finds that the composition of the landscape surrounding coffee farms helps predict production in a spatially explicit approach, but these metrics cannot detect the impact of the landscape in an aspatial approach. The findings highlight the importance of landscape spatial structure in the stability of coffee production.
