Paronychia leucochthonicola (Caryophyllaceae: Paronychieae), a new species of the San Luis Valley, north-central New Mexico and adjacent Colorado.
Published: 2026-02-03
Subjects: Botany
Paronychia leucochthonicola C.E.V.Alexander sp. nov. is described from two population complexes in the San Luis Valley, one along the Rio Grande Gorge west of Taos (New Mexico), the other centered on Flat Top in the San Luis Hills (Colorado). This is a rare species, occurring in narrow bands of habitat along rimrock. These plants have previously been identified as either Paronychia pulvinata or [...]
Spatial resolution and temperature matter for mapping Cerrado wetlands and dry grasslands
Published: 2026-02-03
Subjects: Ecology and Evolutionary Biology
Wetlands in the Brazilian Cerrado play key roles in regional carbon and water cycles but remain poorly mapped due to their patchy distribution and seasonal variability. Therefore, knowing where and when they occur is urgently needed. To address this gap, we evaluated how spatial resolution and inclusion of thermal (on top of traditional multispectral) data affected wetland vs. dry grassland [...]
The conditional ecology of pest suppression: A general mechanistic framework for predicting landscape effects on biological control
Published: 2026-02-03
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology
Landscape heterogeneity often increases natural enemy abundance, yet its effects on crop pest suppression are strikingly inconsistent across empirical studies. We developed a trait-based simulation framework to identify the general mechanisms linking landscape structure to realized pest load. Across >150 in silico experiments, we show that landscape attributes influence biological control by [...]
Factors influencing the use of scientific evidence in conservation practice and policy: insights from a systematic map
Published: 2026-02-02
Subjects: Biodiversity, Life Sciences, Social and Behavioral Sciences
Evidence-based conservation can lead to better outcomes for biodiversity, through the integration of scientific evidence with other forms of knowledge to make transparent and effective decisions. However, despite efforts to promote evidence-based practice, many management and policy decisions do not incorporate scientific information. To strengthen the interface between science and [...]
Systematic review of triploidy among parasitic worms
Published: 2026-02-02
Subjects: Life Sciences
Parasitic worms have significant medical, veterinary, and economic importance. Numerous studies have therefore addressed various aspects of parasitic worms’ biology. In contrast, the ploidy of parasitic worms remains comparatively understudied, despite a few known triploid species. Polyploidy is known to have phenotypic and genetic effects in animals, which can lead to changes at the evolutionary [...]
What is a plant chemotype anyway?
Published: 2026-02-02
Subjects: Life Sciences
Many plant species show chemical polymorphisms regarding the composition of specialized metabolites belonging to certain chemical families. This led to the classification of chemotypes, that is, groups of plants that can be distinguished by their chemical profiles of metabolites within one chemical family. We present existing definitions and approaches for classifying chemotypes, and describe [...]
Putting the ‘Adaptive’ in Adaptive Monitoring: From Fast Data to Meaningful Ecological Change
Published: 2026-02-02
Subjects: Life Sciences
Despite repeated calls for ‘adaptive monitoring’, monitoring programs typically rely on fixed protocols that fail to capture the complex and dynamic natural world. New technologies offer this long sought flexibility, yet paradoxically risk our ability to detect trends by generating fragmented, high frequency data untethered to broader monitoring objectives. Here, we introduce ROAM [...]
Diversity comes at a cost: multifaceted diversity reduces plant community stability in peatlands
Published: 2026-02-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. Understanding how ecological stability relates to diversity is of crucial importance under global change. Greater biodiversity is expected to stabilize aggregate community properties through compensatory dynamics, as species fluctuate asynchronously and offset one another. Yet, diversity-stability relationships are not straightforward and can vary across and within ecosystems, particularly in [...]
Creating opportunities for coexistence to overcome the food–biodiversity challenge
Published: 2026-02-02
Subjects: Life Sciences
Coexistence with biodiversity in agricultural landscapes is a global vision by 2050. However, the co-occurrence of wildlife and human food production often results in conflicts which require resolution. Therefore, agroecological landscapes that emerge when sharing land ultimately require achieving human-nature coexistence. We conceptualize human-nature coexistence as an n-dimensional space [...]
Integrating evolutionary theory into a framework for the mechanistic evaluation of candidate anti-aging interventions
Published: 2026-01-30
Subjects: Life Sciences
Despite decades of research into the molecular hallmarks of aging, geroscience lacks a unifying framework to guide the development of effective anti-aging interventions. Here, we integrate two leading evolutionary theories—the Disposable Soma Theory and Hyperfunction Theory—into a layered model of aging biology, the “Aging Onion”. In this framework, aging arises both from persistent activity of [...]
Growth–reproduction trade-offs are common but changing in woody plants: a meta-analysis
Published: 2026-01-30
Subjects: Life Sciences
Growth and reproduction draw on a common resource pool, yet empirical studies of woody plants report widely differing relationships between seed production and growth. Here we synthesize 685 estimates from 78 studies covering 79 woody species to test how growth–reproduction correlations vary across time, species, and environments. Growth and reproduction measured within the same year were [...]
Multi-provenance assisted seed dispersal slows range contractions under climate change.
Published: 2026-01-30
Subjects: Life Sciences
Rapid climate warming threatens the persistence of temperate European forests, raising urgent questions about whether traditional reliance on local seed sources remains viable. Using Quercus petraea in France as a model system, we combined provenance-specific species distribution models with a dynamic range-shift model (simRShift) to evaluate climate-informed assisted dispersal under SSP5-8.5 [...]
One dataset, four meta-analyses: synthesising mean effects, within-population variability, and between-population heterogeneity in ecology
Published: 2026-01-30
Subjects: Agriculture, Ecology and Evolutionary Biology
Ecological syntheses (meta-analysis) usually ask "what is the average effect?", but many ecological questions also depend on whether outcomes become more or less variable and whether effects are predictable across contexts. We show how the same dataset can support a coherent workflow that separates: (i) within-population variability (dispersion among individuals or sampling units inside studies) [...]
Decoding Benthic Macroinvertebrate Communities in Freshwater Ecosystems Leveraging Environmental DNA
Published: 2026-01-29
Subjects: Terrestrial and Aquatic Ecology
Benthic macroinvertebrates are key indicator groups within freshwater ecosystems, with their community being closely tied to ecosystem functioning. Environmental DNA (eDNA) technology, with its high sensitivity and non-invasive nature, provides a promising tool for studying the spatiotemporal dynamics of benthic macroinvertebrate communities, their responses to anthropogenic disturbances, and the [...]
The true scope of global wildlife trade is obscured by data gaps
Published: 2026-01-29
Subjects: Biodiversity, Ecology and Evolutionary Biology
Overexploitation of wildlife is a major driver of biodiversity loss. International wildlife trade is regulated and monitored at local, national, regional and global scales through a variety of mechanisms, including Multilateral Environment Agreements (MEAs), with CITES playing a key role. Whilst databases and systems are available to measure, monitor, and manage legal trade, the data for species [...]
