Deep learning reveals ecological decoupling and rate heterogeneity in Hymenoptera wing evolution

Quantifying biomorphological evolution and integrating phenotypic data into large-scale ecological and evolutionary studies are often limited by the scalability, subjectivity, and poor interpretability of existing methods. We introduce HAIKA (Hierarchical Attention-based Interpre...

Change in the demographic dynamics of a spatially structured population of a colonial waterbird after a perturbation affecting a large colony

Localized perturbations may affect spatially structured populations (SSPs) as a whole by altering dispersal between patches. Yet, such large-scale consequences remain poorly understood and may depend on the proportion of the SSP affected by the perturbation. Here, we used correla...

The geometry of gametic dispersal in a flying mammal, Rhinolophus hipposideros

Abstract Dispersal influences population and evolutionary dynamics, in a manner that depends on by which dispersal strategies gene flow occurs. In some species, mating partners move exclusively for mating, dispersing genes but not individuals. This is the case in many bat species...

Benchmarking a new urban scheme in the ORCHIDEE 2.2 land surface model

Urban areas change natural surface energy and water balances, yet some land surface models still represent cities as natural surfaces. In this study, we present the development of a one-tile urban scheme for the ORCHIDEE land surface model, designed to improve the representation...

Phylogeny of Mastigitae sheds light on a hundred‐million‐year‐long morphological stasis of the extant genus Clidicus Laporte (Coleoptera: Staphylinidae: Scydmaeninae)

Mastigitae comprise 15 genera, of which seven are extinct, and species of two extant genera are also documented as fossils. The rich fossil record makes Mastigitae exceptional among Staphylinidae. Based on results of phylogenetic analyses comprising 33 extant species, 10 dated fo...

Dual northward overseas radiation from Japanese islands shaped the phylogeography of North-East Asian tree frog

The tree frog Dryophytes japonicus has a broad geographic distribution in northeastern Asia, comprising two major genetically divergent clades whose geographic boundary is located within the Japanese mainland. However, the evolutionary and adaptive mechanisms underlying this wide...

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dar...

New record and description of a male Murina kontumensis (Kon Tum Tube-nosed Bat) from Vietnam

Abstract The Kon Tum Tube-nosed Bat ( Murina kontumensis Son et al. 2015. A new species of the genus Murina (Chiroptera: Vespertilionidae) from the Central Highlands of Vietnam with a review of the subfamily Murininae in Vietnam. Acta Chiropterol. 17: 201–232) was described from...

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit ( Parus major ) territories across Europe

Urbanisation alters resource availability and exposes wildlife to novel environmental stressors, potentially driving phenotypic divergence. Carotenoid-based plumage colouration is a condition-dependent trait linked to dietary carotenoid acquisition and physiological allocation tr...

Photovoltaic panels affect arthropod and plant communities: a systematic review

Due to climate change, photovoltaic facilities are being rapidly scaled up. However, such a development can come at a cost for biodiversity. We conducted a systematic review, including a critical appraisal, and meta-analyses to better understand the effects of photovoltaic panels...

Migration and tuberculosis transmission in Hamburg, Germany: insights from 25 years of molecular epidemiology

Abstract Background Tuberculosis (TB) epidemiology in low-incidence settings is increasingly influenced by the importation of Mycobacterium tuberculosis complex (Mtbc) strains from high-incidence regions. Globally, more virulent “generalist” lineages such as Lineage 2 (L2) and Li...

Molecular epidemiology and management of non-tuberculous mycobacteria isolated from patients in Ukraine, 2022–2024

Non-tuberculous mycobacteria (NTM) are increasingly recognized worldwide as significant causes of chronic pulmonary disease, particularly among individuals with underlying structural lung disorders or immunosuppression. However, data on the epidemiology and clinical management of...

Evidence of hydrodynamic control of phytoplankton seasonality in a tropical urban estuary

Tropical urban estuaries receive year-round nutrient loads, yet their strongest phytoplankton blooms often occur in the dry season. The proximate control on this seasonality remains unresolved in wastewater-impacted tropical systems. Here we apply a transient one-dimensional Carb...

Hydraulic function of medullary bundles in a tropical root climber

Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function...

Paleoenvironmental and paleoclimatic reconstruction in the Western Mediterranean during the Late Early Pleistocene

Abstract. The major climate change recorded during the Early-Middle Pleistocene Transition (1.4–0.4 Ma) is characterized by an increase in the length of climatic cycles from 41 to 100 ka. During this period, the Mediterranean climate underwent aridification associated with a drop...

Life finds its way in seaports: environmental DNA monitoring in the Grand Port Maritime de Guadeloupe shows vertebrate richness but reduced phylogenetic diversity

Abstract Ports are increasingly recognized as distinct urban marine ecosystems (UME) shaped by intense human activities, yet their biodiversity remains poorly documented, particularly in tropical regions. Environmental DNA (eDNA) metabarcoding offers a powerful, non-invasive appr...

Zoological biobanks as a resource for microplastic analysis: a Py-GC-MS/MS case study on sea cucumbers

Microplastics have spread through every ecosystem studied. Yet, documenting their spatiotemporal distribution remains challenging, particularly in marine environments where sampling is costly and difficult. Archived specimens in zoological biobanks offer an underused resource for...

Local Trade‐Offs Shape Flower Size Evolution Across Arabidopsis thaliana Distribution

The remarkable variation in floral form and size is thought to have driven the evolutionary radiation of angiosperms and has traditionally been attributed to pollinator-mediated selection on floral displays, yet emerging evidence indicates that abiotic environmental factors can a...

Environmental drivers of litter- and soil-dwelling springtail communities across European forests, assessed by morphotaxonomy and soil DNA metabarcoding

Springtails are abundant in forest litter and soils, where they play a crucial role in the transformation and decomposition of organic matter. However, most data on springtail communities originates from studies at the local and regional levels, while larger-scale studies are lac...

Anticancer and Cardioprotective Properties of Medicinal Mushrooms: Current Evidence and Future Prospects

Introduction: Cardiotoxicity is an undesirable side effect of chemotherapy that limits the effectiveness of cancer treatment. Almost all cardiotoxic agents cause cardiovascular complications, leading to oxidative stress and other pathological conditions. The search for bioactive...
