Community herbivory in tropical montane rainforests is affected by phylogenetic plant diversity, specific leaf area, and leaf nutrient concentrations
Published: 2024-12-12
Subjects: Life Sciences
Arthropod herbivores modulate ecosystem structure, productivity, and nutrient cycling. While previous work has shown that plant-herbivore interactions for individual species are shaped by abiotic factors, traits, and the surrounding plant community, the relative contribution of abiotic and biotic factors for herbivory at the community level remains elusive. Here, we use a structural equation [...]
Global patterns of insect herbivory across forest canopies and understories: Insights from a tropical case study and a global comparison
Published: 2024-12-11
Subjects: Life Sciences
Several studies have examined global patterns of insect herbivory, revealing variations with latitude, elevation, and temperature. However, less attention has been given to herbivory patterns at smaller spatial scales, particularly the comparison between forest canopies and understories. Understanding these finer-scale patterns is crucial for predicting ecological responses to both natural and [...]
Greenspace modifies the associations between heat and mortality: A systematic review and meta-analysis of observational studies
Published: 2024-12-11
Subjects: Medicine and Health Sciences
Greenspace has been increasingly examined for its potential associations with heat-related mortality. However, quantitative synthesis of evidence on this association remains limited. We conducted a systematic review and meta-analysis of observational studies published through July 20, 2025, examining the relationship between effect modification of greenspace on heat-related mortality risk. We [...]
The Development and Evolution of Arthropod Tagmata
Published: 2024-12-10
Subjects: Biology, Cell and Developmental Biology, Developmental Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences
The segmented body plan is a hallmark of the arthropod body plan. Morphological segments are formed during embryogenesis, through a complex procedure involving the activation of a series of gene regulatory networks. The segments of the arthropod body are organized into functional units known as tagmata, and these tagmata are different among the arthropod classes (e.g. head, thorax and abdomen in [...]
iNaturalist as a platform for documenting Chilean funga
Published: 2024-12-09
Subjects: Biodiversity, Environmental Policy, Life Sciences, Other Life Sciences
This study analyzes the impact of iNaturalist on the recording and documentation of fungi in Chile from 2008 to 2024, highlighting its role in integrating citizen science into biodiversity monitoring. This community effort—which currently totals more than 63,000 observations representing 1,245 species—is concentrated in the central and southern regions of the country, mainly in urban areas, where [...]
Microbes as conservation targets
Published: 2024-12-09
Subjects: Life Sciences
A world without microorganisms would lack essential processes that support life. The degradation or loss of microbiomes will lead to severe disruptions in ecosystems, nutrient cycling, and the climate; failures in food production; and crises in animal and human health. Yet, microbes remain largely excluded from nature conservation efforts. Current microbial management predominantly relies on the [...]
Phenological and life history/form idiosyncraticity of facultatively annual Cistanthe philhershkovitziana Hershk. (C. sect. Cistanthe; Montiaceae) in Chile’s southern Central Littoral Zone, with comments on the incidence of the facultative annual condition among “Portullugo” (Caryophyllales) and o
Published: 2024-12-09
Subjects: Biodiversity
Cistanthe philhershkovitziana Hershk. was described from the north-central Chilean coast in 2018. Based on the apparent absence of plants during drought years, it was described as the only species of C. sect. Cistanthe with a putatively annual life history (~therophytic life form). The species occurs primarily in coastal habitats, but also in some seasonally moist sites up to perhaps 50 km [...]
Shorebirds are shrinking and shape-shifting: declining body size and lengthening bills in the past half-century
Published: 2024-12-09
Subjects: Life Sciences
Animals are predicted to shrink and shape-shift as the climate warms; declining in size, while their appendages lengthen. Determining which types of species are undergoing these morphological changes, and why, is critical to understanding species responses to global change, including potential adaptation to climate warming. We examine body size and bill length changes in 25 shorebird species [...]
Don’t ask “when is it coevolution?” — ask “how?”
Published: 2024-12-09
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Coevolution has come to be widely understood as specific, simultaneous, reciprocal adaptation by pairs of interacting species. This strict-sense definition arose from a desire for conceptual clarity, but it has never reflected the much wider diversity of ways in which interacting species may shape each other’s evolution. As a result, much of the literature on the evolutionary consequences of [...]
The feasibility principle in community ecology
Published: 2024-12-09
Subjects: Life Sciences
The structure and function of ecological communities emerge from interactions among populations within specific environmental contexts. Yet we still lack general principles that explain how communities assemble, which patterns we should expect, and when transitions occur across diverse settings. To address this challenge, I propose the feasibility principle in community ecology as a guide to [...]
Code-sharing policies are associated with increased reproducibility potential of ecological findings
Published: 2024-12-09
Subjects: Life Sciences
Software code (e.g., analytical code) is increasingly recognised as an important research output because it improves transparency, collaboration, and research credibility. Many scientific journals have introduced code-sharing policies; however, surveys have shown alarmingly low compliance with these policies. In this study, we expanded on a recent survey of ecological journals with code-sharing [...]
Transparency and reproducibility in invasion science
Published: 2024-12-06
Subjects: Botany, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Policymakers and practitioners overseeing invasive species management depend on reliable research for guidance. Transparency and reproducibility are core features of reliable research, and prerequisites for outcomes to be independently replicated within the same or different systems. These features are evidently lacking in many science disciplines, including Ecology. In this Discussion [...]
Synthesis of nature’s extravaganza: an augmented meta-meta-analysis on (putative) sexual signals
Published: 2024-12-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution
Colourful body parts and bizarre displays that do not seem to contribute to the survival of individuals that express them have puzzled biologists for centuries. Sexual selection theory posits that these traits evolved because more conspicuous individuals attract more mates and experience greater fitness, yet evidence for this remains fragmented. Our augmented meta-meta-analysis of 41 [...]
Different sources of wind turbine data produce sharp differences in collision risk estimates for foraging vultures
Published: 2024-12-06
Subjects: Biodiversity, Environmental Monitoring, Systems Biology, Zoology
Multiple studies assessed the collision risk of different vulture species with wind turbines. However, they relied on different sources of wind turbine data, and the effect of this data heterogeneity, on the estimated collision risk and the comparability of these assessments, has not been investigated. We used GPS and accelerometer data, collected from 6 adult Griffon Vultures living in Sardinia [...]
Unbaited underwater video evidences the presence of previ-ously unrecorded fish species, sea krait (Laticauda sp.) and a high frequency of sharks at a remote reef complex (Coral Sea Marine Park, Southwest Pacific)
Published: 2024-12-06
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
The Chesterfield-Bellona atolls and reefs are a vast reef complex located in the Coral Sea Marine Park, estab-lished in 2014 in the New Caledonian Economic Exclusive Zone. In 2013, the New Caledonia government supported the first assessment of fish and benthic habitats conducted in all habitats and over the entire area. The assessment provided a primary knowledge base for establishing the [...]
