Summary: The internal structure of shells showed different effects on resource-correlated RHP for hermit crabs, depending on their role as owner or intruder during contests. Owners resisted more evictions in intact shells, while the presence of a columella in intruders' shells did not affect their likelihood of eviction.

Summary: There is significant evidence on how resource nexus affects resources' overall performance across sectors. However, the interactions among different resource flows and their impact on economic systems, including resource allocation, production efficiency, input-output relationships, and environmental sustainability, are not well understood. This study integrates water, land, and food input-output networks into a supernetwork framework to analyze resource flows and reveal the interactions among heterogeneous resource systems under the water-land-food nexus. The results provide insights into resource efficiency and can inform resource management strategies at different levels.

Summary: This study examines the interactions of wind energy project siting, resource potential, and power system evolution, revealing that different siting regimes can significantly impact future wind capacity, especially in scenarios with high demand for clean energy. Stringent siting restrictions lead to higher electricity prices and emissions, which should be balanced with local impacts.

Summary: Long-term vegetation plots represent a significant investment in ecology research, but linking plant and animal data is challenging due to human interference. Recent advances in automated animal sound identification offer a solution to study plant-animal interactions without disturbance. By deploying autonomous recording units (ARUs) and using Animal Sound Identifier (ASI) software, researchers were able to detect frugivorous bird vocalizations and observe significant positive relationships between bird and fruiting tree species. These findings demonstrate the potential of ARUs and automated voice identification to study animal distribution and movement in large vegetation plots and link animal data to plant data.

Summary: This study assesses and analyzes the collision risks of wind turbines and power lines to birds in Europe and North Africa based on GPS location data of tracked birds. The results show that some bird species consistently fly at heights where they are at risk of collision. In the study region, 13.6% of the area is classified as highly sensitive to wind turbines and 9.4% is classified as highly sensitive to power lines, with hotspots of collision vulnerability scattered across the region, particularly in central Europe, near the strait of Gibraltar, and the Bosporus in Turkey.

Summary: Understanding the migratory community dynamics of river networks is crucial for maintaining the integrity of lotic systems. In a study in northern Japan, changes in population density of spawning chum salmon and a mobile consumer (juvenile masu salmon) were observed in a lowland, spring-fed tributary during a 48.5 mm autumn rainfall event. Both species showed an increase, followed by a decrease, in population density after the rainfall event, with the changes in chum salmon closely linked to rainfall intensity and a delayed peak in masu salmon. Gut content analysis indicated a higher consumption of chum salmon eggs in the spring-fed tributary, suggesting that the preferential migration of chum salmon into such habitats for spawning leads to an accumulation of juvenile masu salmon and increased egg consumption.

Summary: The study provides a methodological framework for understanding the movement mechanisms necessary for building predictive models of animal space use. By analyzing individual movement patterns, constructing step selection models, and comparing predicted and empirical patterns, the researchers iteratively improve the model's predictive power. The effectiveness of this method is demonstrated through a case study on a population of feral pigs in Mississippi, USA, which identified missing features in the model.

Summary: Despite the common assumption that trees have negative effects on local hydrological budget, this study demonstrates that trees can actually have positive effects by reducing surface run-off and improving soil infiltrability and groundwater recharge. The research also found that during wet and dry seasons, trees and grasses exhibit niche partitioning for water resources, with trees relying heavily on groundwater during the dry season. Additionally, isotopic data suggest that trees reduce evaporative water losses from the soil surface and enhance preferential flow, contributing to the positive effects on the local water balance and providing implications for landscape management.

Summary: The study systematically surveyed Apocynaceae for retronecine-type PAs and confirmed the presence of PAs in the Echiteae tribe, highlighting the utility of PAs in tribal delimitation. The study also reported PAs in other lineages with some uncertainty, as well as identified potential sources of human exposure to toxic PAs in medicinal and food plants. The detection of PAs varied among samples of Echites umbellatus, with intra-individual plasticity contributing to this variation.

Summary: Pollination in Geettarda scabra is primarily done by hawkmoths, with butterflies possibly serving as secondary pollinators. The study also suggests that morning pollinators may play an important role due to afternoon and evening rains extending into the night when the plants flower.

Summary: This study investigates the temporal changes in diversity of pine rockland Fabaceae induced by anthropogenic factors. Results show fluctuations in collection diversity over time, with native species frequency highest prior to 1920 and nonnative legume richness increasing with decades. The historical distributions of Fabaceae species collections are documented, aiding in conservation and restoration efforts in the imperiled pine rocklands of southern Florida.

Summary: This study found that in situations where photosynthates are limited, self-pollinated plants are more likely to have ovules aborted in their fruits, while cross-pollinated fruits tend to produce higher quality seeds. There is a trade-off between seed number and seed mass in fruits, and seed position in the fruit can also affect seedling vigor.

Summary: When weeds are present in mango farms, they can provide pollen and nectar, increasing the abundance and diversity of beneficial insects. This study found that weeds significantly increased the abundance and diversity of pollinators and natural pest control agents on mango trees. Additionally, soil conditions were improved with the presence of weeds. These results highlight the importance of tolerating a certain level of weed species for the biodiversity and sustainability of agricultural ecosystems.

Summary: When plants are defoliated, their response varies. Some may be stunted in growth, while others may compensate and reach the same size as undamaged plants. A few may even overcompensate and end up larger than before. In this study, we examined how different Senna species reacted to defoliation and found that only three out of five displayed shorter height with more damage. Additionally, only one species showed a decrease in the number of extrafloral nectaries, suggesting that extrafloral nectar production is not inducible in these Senna species.

Summary: Floral Scent in Guettarda scabra: Insights into Chemical Ecology and Pollinator Attraction
This study investigated the floral scent of Guettarda scabra, a night-blooming species with short- and long-styled floral morphs. The results showed that the fragrance of G. scabra consisted mainly of benzenoid and terpenoid compounds, with benzeneacetaldehyde and (E)-beta-ocimene as the dominant components. The chemical profiles of the floral scent were similar in both morphs, and staining assays revealed that the corolla lobes, anthers, and stigma were the primary sources of the scent. These findings provide important insights into the chemical ecology and pollinator attraction of G. scabra.
