Subjects: Biodiversity, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability, Terrestrial and Aquatic Ecology
1. Climate change poses significant threats to biodiversity. To ensure the long-term persistence of species, protected areas must be established in locations that will safeguard suitable habitats in the future. Although statistical models can predict where such habitats may occur under different future scenarios, designing protected areas that can effectively protect these habitats across a wide [...]
An integrated framework for unifying our understanding of nonconsumptive predation risk effects
Published: 2026-06-12
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Predation risk can induce risk-induced trait responses (RITRs) – changes in prey defensive traits including behavior, morphology, life history, and physiology – thought to have profound effects on prey fitness and population dynamics (termed ‘nonconsumptive effects’). Yet, predicting the magnitude of RITRs and their fitness consequences remains difficult because outcomes depend heavily on [...]
Trophic interactions of ants are robust to tree species loss
Published: 2026-06-05
Subjects: Entomology, Life Sciences, Terrestrial and Aquatic Ecology
1. How changes in habitat conditions influence insect diversity has been intensively studied. However, whether trophic interactions of insects are also influenced by such changes is largely unknown. Higher habitat heterogeneity is often hypothesized to promote niche partitioning and complementarity in resource use among interacting species, yet evidence from animal interaction networks is sparse. [...]
Recreational fishing drives the global spread of aquatic non-native species
Published: 2026-06-04
Subjects: Aquaculture and Fisheries Life Sciences, Terrestrial and Aquatic Ecology
Recreational fishing provides substantial socio-economic benefits worldwide, yet its role in driving aquatic biological invasions remains insufficiently understood. Here, we assessed global evidence for recreational fisheries-mediated introductions of aquatic non-native species. Using a systematic review of 140 retained studies, we compared temporal trends, geographic coverage, introduction [...]
Two centuries of decline and partial recovery of fish in rivers of post-industrial northeast England: lessons for global rivers in the Anthropocene
Published: 2026-06-03
Subjects: Terrestrial and Aquatic Ecology
Understanding the historical decline in ecological condition of rivers, their fish stocks, and of their restoration, offers one perspective by which contemporary threats to river fishes in less developed regions may be assessed. We explore the decline and recovery of fish populations in rivers (Tyne, Wear, Tees) of post-industrial northeast England. Before ~1850, Atlantic salmon (Salmo salar) and [...]
Cryptic diversity constrains biogeographical inference in microscopic animals: evidence from bdelloid rotifers in Greenland
Published: 2026-06-01
Subjects: Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
Species are fundamental units of biodiversity, yet their delimitation remains challenging in many organismal groups. The increasing use of DNA data has revealed widespread cryptic diversity, in which genetically distinct lineages are morphologically indistinguishable. Consequently, many morphology-based biogeographical inferences have likely overestimated species ranges, particularly in [...]
Canopy closure re-establishes ants in young tree plantations, while low soil pH limits ant diversity
Published: 2026-05-28
Subjects: Entomology, Life Sciences, Terrestrial and Aquatic Ecology
1. Tree species richness is known to enhance biodiversity and ecosystem functioning, but its effects across trophic levels during forest restoration remain insufficiently understood. In reforestation on complex terrain, habitat complexity may moderate the effect of canopy closure on animal community reassembly, a relationship further shaped by the abiotic environment. 2. Ants, as key functional [...]
China must revise its regulation for managing non-native invasive species
Published: 2026-05-27
Subjects: Political Science, Terrestrial and Aquatic Ecology
Biological invasions are a leading contributor to the global biodiversity crisis, yet existing regulatory frameworks are challenged by definitions of ‘non-native’ species that are based on geopolitical rather than ecological boundaries. This perspective highlights the critical disconnect between administrative jurisdictions and biogeographic units, with focus on China’s biosecurity laws. These [...]
Navigating Spatial Trade-offs in Restoration Planning: A Multi-Objective Optimization Framework Integrating Ecological Feasibility
Published: 2026-05-27
Subjects: Biodiversity, Life Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics, Sustainability, Terrestrial and Aquatic Ecology
Ecosystem restoration requires decision-support tools capable of balancing ecological benefits under limited resources while explicitly accounting for the long-term likelihood of restoration success. Despite its recognized importance, ecological feasibility has rarely been formulated as an optimization objective in spatial planning, typically being treated only as a constraint or biophysical [...]
Insufficient environmental protection by the European regulatory framework for pesticides
Published: 2026-05-20
Subjects: Agriculture, Environmental Health Life Sciences, Terrestrial and Aquatic Ecology, Toxicology
Schriever et al. (2025) argue that environmental risk assessment of pesticides in the European Union is sufficiently protective and that regulatory thresholds are rarely exceeded. Here, we re-examine these claims based on new and previous evidence from monitoring, systematic reviews, and different types of field studies. The clear outcome is that measured pesticide concentrations frequently [...]
Designing for nature doesn't cost the Earth
Published: 2026-05-19
Subjects: Biodiversity, Life Sciences, Terrestrial and Aquatic Ecology, Urban Studies and Planning
1. A key barrier to the development of nature positive cities is the unknown cost of implementing novel urban design elements. Strict budgets and government approval processes make it challenging for developers to trial new approaches, meaning most developments rarely deviate from ‘business-as-usual’ (BAU). Further research is urgently needed to overcome this barrier to innovation and help [...]
Expanding the sentinel approach through multimodal integration: resolving underlying ecological processes with eDNA and computer vision
Published: 2026-05-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences, Terrestrial and Aquatic Ecology
Sentinel approaches provide a semi-controlled method for quantifying in-field ecological interactions and processes while reducing bias and labour. They are, however, limited by difficulties ascribing taxonomic identities, behavioural context and temporal resolution to interacting agents. The integration of additional sources of data, including the analysis of DNA left behind on sentinel objects [...]
An epibiotic association between burrowing and sessile bivalves on the Amazon continental shelf: implications for ecological facilitation in sediment-dominated environments
Published: 2026-05-12
Subjects: Life Sciences, Terrestrial and Aquatic Ecology
From the perspective of ecological facilitation theory, we report an epibiotic association between two mollusk species with contrasting lifestyles, Chama macerophylla Gmelin, 1791 (sessile) and Tucetona pectinata (Gmelin, 1791) (burrowing), on the Amazon continental margin. Specimens were collected using a Van Veen dredge near the shelf break and in the vicinity of AP3 blocks recently offered for [...]
OdoCocktail-Japan: Primer sets to enrich environmental DNA of Japanese Odonata species
Published: 2026-05-12
Subjects: Biodiversity, Entomology, Terrestrial and Aquatic Ecology
Monitoring is essential to conserve and recover biodiversity. Environmental DNA (eDNA)-based metabarcoding analysis has been recognized as a cost-effective and efficient method to monitor species, but it still has limitations, such as insufficient reference databases and lack of primer sets suitable to detect target species. As biological indicators of freshwater habitats, Odonata species have [...]
Identifying knowledge gaps on simultaneous above- and belowground organism responses to global change
Published: 2026-05-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Global change affects all terrestrial organisms regardless if they live above or below the ground. Even though they are strongly linked by various direct and indirect interactions, organisms can respond very differently to global change stressors, due to different features of above- and belowground compartments. Many different organism groups have shown declines in diversity, abundance or biomass [...]
