Refining the trophic diversity, ecological network structure, and bottom-up importance of prey groups for temperate reef fishes
Published: 2023-11-07
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Marine Biology
Marine fish communities are highly diverse, including all trophic levels of consumers and contributing to many ecosystem processes. Understanding the specific functional roles of many fish species and the importance of different prey groups for sustaining fish communities has, however, been limited by the historical classification of fishes into a few coarse trophic guilds. Using detailed diet [...]
Comparative life-history responses of lacewings to changes in temperature
Published: 2023-11-04
Subjects: Life Sciences
Insects play a crucial role in all ecosystems, and are increasingly exposed to higher in temperature extremes under climate change, which can have substantial effects on their abundances. However, the effects of temperature on changes in abundances or population fitness are filtered through differential responses of life-history components, such as survival, reproduction, and development, to [...]
Sharing the burden: Cabbage stem flea beetle pest pressure and crop damage are lower in rapeseed fields surrounded by other rapeseed crops
Published: 2023-11-04
Subjects: Agriculture, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
The cabbage stem flea beetle (Psylliodes chrysocephala) is a significant pest of rapeseed (Brassica napus). Feeding by adult P. chrysocephala can cause severe leaf damage and larval infestation can reduce stem strength, both of which impact crop growth and development, causing substantial yield losses and economic damage. The structure of the agricultural landscape can regulate herbivorous pest [...]
Signatures of global processes shaping the structure of microbial co-occurrence networks
Published: 2023-11-01
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences
Co-occurrence networks offer insights into the complexity of microbial interactions, particularly in highly diverse environments where direct observation is challenging. However, identifying the scale at which local and non-local processes structure co-occurrence networks remains challenging because it requires simultaneously analyzing network structure within and between local networks. In this [...]
The behavioural costs of overcrowding for gregarious cave-dwelling bats
Published: 2023-11-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
1. Bats are known for their gregarious social behaviour, often congregating in caves and underground habitats, where they play a pivotal role in providing various ecosystem services. Studying bat behaviour remains an underexplored aspect of bat ecology and conservation despite its ecological importance. 2. We explore the costs and impacts of overcrowding on bat social behaviour. This study [...]
Endocrine flexibility can facilitate or constrain the ability to cope with global change.
Published: 2023-10-30
Subjects: Life Sciences
Global climate change has increased average environmental temperatures world-wide, simultaneously intensifying temperature variability and extremes. Growing numbers of studies have documented phenological, behavioral, and morphological responses to climate change in wild populations. As systemic signals, hormones can contribute to orchestrating many of these phenotypic changes. Yet little is [...]
Industrial fishing compliance with a new marine corridor near the Galapagos Islands
Published: 2023-10-30
Subjects: Agricultural and Resource Economics, Aquaculture and Fisheries Life Sciences, Life Sciences, Marine Biology
Examining fishing pressure in under-resourced marine regions still presents a challenge to understanding patterns of fishing pressure. These issues are compounded in areas with complex marine zoning regulations or those that have changed over time. Satellite-based positioning tracking of fishing vessels has helped identify ocean-wide fishing effort distribution and potential encroachments into [...]
The dispersal potential of endangered plants versus non-native garden escapees
Published: 2023-10-30
Subjects: Biodiversity, Life Sciences, Plant Sciences
Amidst global challenges like climate change, plant dispersal corridors are essential. In human-dominated landscapes, urban and rural green spaces are key dispersal avenues. Non-native plants are known to benefit from these, yet the potential benefits for endangered plants remain unclear. To address this question, I compared dispersal traits of endangered native plants with those of [...]
Delivering on a promise: Futureproofing automated insect monitoring methods
Published: 2023-10-26
Subjects: Life Sciences
Due to rapid technological innovations, the automated monitoring of insect assemblages comes within reach. However, this continuous innovation endangers the methodological continuity needed for calculating reliable biodiversity trends in the future. Maintaining methodological continuity over prolonged periods of time is not trivial, since technology improves, reference libraries grow, and both [...]
Global research priorities for historical ecology to inform conservation
Published: 2023-10-26
Subjects: Arts and Humanities, Life Sciences, Social and Behavioral Sciences
Historical ecology draws on a broad range of information sources and methods to provide insight into ecological and social change, especially over the past ~12,000 years. While its results are often relevant to conservation and restoration, insights from its diverse disciplines, environments, and geographies have frequently remained siloed or underrepresented, restricting their full potential. [...]
Uneven genetic data limits biodiversity assessments in protected areas globally
Published: 2023-10-26
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Policy, Genetics, Life Sciences
Increasing the extent of protected areas (PA) through 30x30 and other area-based conservation initiatives can help to achieve global biodiversity conservation goals across all biodiversity levels. However, intraspecific genetic variation, the foundational level of biodiversity, is rarely explicitly considered in PA design or quality performance assessments. Repurposing existing genetic data could [...]
Neglected biodiversity and ecological functioning – fish community structure associated with Antipatharia (black corals) on shallow reef ecosystems
Published: 2023-10-26
Subjects: Life Sciences
Addressing anthropogenic threats compromising the persistence of tropical marine ecosystems requires an understanding of the fundamental ecological functions these organisms fulfil. Habitat provision is a major function of corals in tropical marine ecosystems, although most research in this area has concentrated on scleractinians (hard corals). Here, we provide one of the first empirical studies [...]
Integration of multimodal cues does not alter mean but reduces among-study variance in avian responses to predators: a systematic review and meta-analysis
Published: 2023-10-26
Subjects: Ecology and Evolutionary Biology, Life Sciences
Despite a wealth of studies documenting prey responses to perceived predation risk, researchers have only recently begun to consider how prey integrate information from multiple cues in their assessment of risk. We conduct a systematic review and meta-analysis of studies that experimentally manipulated perceived predation risk in birds and evaluate support for three alternative models of cue [...]
When the microbiome shapes the host: immune evolution implications for infectious disease
Published: 2023-10-23
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Evolution, Immunity, Immunology and Infectious Disease, Immunology of Infectious Disease, Life Sciences, Molecular Genetics, Pathogenic Microbiology
The microbiome includes both “mutualist” and “pathogen” microbes, regulated by the same innate immune architecture. A major question has therefore been: how do hosts prevent pathogenic infections while maintaining beneficial microbes? One idea suggests hosts can selectively activate innate immunity upon pathogenic infection, but not mutualist colonisation. Another idea posits that hosts can [...]
