Summary: Measuring the ecological and economic impacts of invasive species is crucial for managing invaded food webs. A novel approach was proposed to quantify trophic interaction strengths based on abundance, biomass, and diet data, which allowed for estimating economic loss and resilience of invaded food webs. The study revealed that species richness and food web complexity can affect resistance and economic impact of invasive species.

Summary: Poplars are fast-growing trees and important resources in agriculture and forestry. However, their rapid growth requires a large amount of water, and irrigation water can contribute to the spread of pathogens. This study analyzed the effects of artificial inoculation with aggressive Phytophthora species on the proteome of a Phytophthora-tolerant hybrid poplar clone, revealing the impact on poplar metabolism and identifying potential markers for Phytophthora tolerance in trees.

Summary: The presence of protected snails in restored stream communities can disrupt vulnerable prey populations and have long-term negative effects on predators. Additionally, mayflies appeared less on surfaces with high snail densities, potentially due to altered resource use. These biotic interactions may form a barrier to successful biotic restoration by preventing colonization of desired vulnerable prey.

Summary: Ecology aims to reveal generalities in species interactions and explain differences in species richness among groups. Through a systematic review, it was found that different types of interactions can predictably impact species diversification and richness patterns.

Summary: Independently, ocean warming and acidification are two major threats to marine organisms, and their interaction has wide-ranging consequences to biological functioning, population and community structure, species interactions, and ecosystem service provision. A multitrophic experiment showed that future ocean acidification and warming had negative consequences on the growth, feeding, and metabolic rate of blue mussels, but had no effect on the predator's growth and metabolism, and even increased its feeding. This differential response between the two species to ocean acidification and warming could lead to fundamental changes in ecosystem structure and functioning.

Summary: Aggressive interactions among bird species often involve the display of weapons and specific visual signals, such as positioning the body towards the opponent, using bright colors, and highlighting certain body parts. Despite differences in species and taxonomic families, the overall patterns of aggressive signals remain consistent, indicating that selection from aggressive interactions may act on the same signaling traits regardless of competitor identity.

Summary: Aggressive interactions play an important role in birds, allowing them to gain resources and defend against competitors. Birds use signals involving sounds and color to communicate and avoid the costs of intraspecific aggression. They display similar aggressive postures and visual signals regardless of the species they are interacting with.

Summary: Interspecific competition between native and invasive alien species can be exacerbated by environmental conditions, especially in delicate ecosystems like Mediterranean coastal wetlands. This study found that the presence of an invasive competitor resulted in changes in ecological adaptations of the native species, with salinity and the presence of the invader acting synergistically to shape the population structure of the native species.

Summary: This study investigated a failed invasion involving an IGP relationship and found that the highly unstable nature of the IGP relationship was the primary cause of the guppy's failure to establish in Florida.

Summary: This study found that climate change-induced range shifts can have negative effects on both shifting and resident species due to strong intraguild interactions. However, the presence of predators can mitigate these negative effects, stabilizing the community.

Summary: Dispersal ability determines the distribution and abundance of species, and is influenced by environmental factors such as density, food availability, and predation. Food availability plays a central role in the spatial structuring of nematode communities.

Summary: Theory suggests that competing species can coexist in a community when intraspecific competition is stronger than interspecific competition. This study found that the evolution of species- and size-dependent competitive asymmetries increased the likelihood of coexistence between interacting species. Furthermore, the research highlights the importance of integrating evolution and trait-based interactions into studies on species coexistence.

Summary: Banker plant systems can control pests sustainably by introducing natural enemies and providing alternative prey. This study investigated the dynamic relationship among the elements of a banker plant system and its impact on aphid pest control. The research system used in the study was the Coccinella septempunctata-Megoura japonica-Vicia faba banker plant system for controlling Myzus persicae on Capsicum annum. The study tested the effects of different release time of predators, different initial numbers of alternative prey, and different initial ratios of target pests/alternative prey on the indirect interaction of two aphids and the biological control effect of shared predators.

Summary: The study on the preferred temperature and thermal range of the black-axil chromis revealed the significant impact of species interactions on thermal ecology. Individual fish showed a greater tolerance for higher temperatures in the presence of a predator, highlighting the limited scope for thermal tolerance under different ecological conditions.

Summary: The study examined seed-animal interactions along an elevation gradient in western Myanmar and found that the removal pattern of seeds by animals varied between seasons and among plant species. This suggests that a one-off survey with few species may not accurately represent overall macroecological patterns of biotic interactions. Future studies should take into account the seasonal and species-specific variability in these interactions.
