Orphan crops of archaeology‐based crop history research

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 562-589, May 2025.
Agrobiodiversity is central to sustainable farming worldwide. Cultivation, conservation and reintroduction of diverse plant species, including ‘forgotten’ and ‘underutilized’ crops, contribute to global agrobiodiversity, living ecosystems and sustainable food production.

Transformation in the Forest Ecosystem of Northeastern China Driven by Human Factors Over the Past 1600 Years

open access: yesEarth's Future, Volume 13, Issue 5, May 2025.
Abstract Human‐driven degradation of forest ecosystems has profoundly altered land cover, disrupted ecosystem functions, and contributed to climate variability. Understanding long‐term changes in forest composition and resilience is crucial for developing effective, evidence‐based restoration strategies. This study presents a 1,600‐year paleoecological

Arctic tundra ecosystems under fire—Alternative ecosystem states in a changing climate?

open access: yesJournal of Ecology, Volume 113, Issue 5, Page 1042-1056, May 2025.
Climate change is altering the Arctic tundra, with fires driving vegetation shifts. We hypothesise that post‐fire recovery, shaped by climate change, may not return to pre‐fire conditions, leading to either increased woody vegetation or grass dominance. Photo: The Mingvk Lake fire, a lightning start, burned nearly 8500 hectares in July 2015.

Review of larval food plant associations of the Agaristinae (Lepidoptera: Noctuidae) in Australia

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract The Australian Agaristinae comprises a small group of predominantly diurnal moths with aposematic larvae and adults that are assumed to be unpalatable to most predators. A critical review of the larval food plants of this subfamily based on published records in the literature, together with unpublished records, is presented.

Long‐Term Fire and Vegetation Change at Cocha Cashu Biological Station, Peru

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
Cocha Cashu is a dynamic system that has experienced various forms of past ecological turnover. However, the dynamism seen at Cocha Cashu was not caused by intensive human activities in the past. ABSTRACT Past human influence from the pre‐Columbian and colonial periods may have played a role in shaping modern Amazonian vegetation.

Conservation status of Erebia palarica Chapman, 1905 (Lepidoptera, Nymphalidae): Local insight and whole distribution perspective

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 370-385, May 2025.
Mark‐release‐recapture data of E. palarica reveals low dispersal rates (<500 m) and small census population sizes (Nc = 303 and 565) in two localities from Serra do Courel (NW Spain). Microsatellite genotypes of four generations (1999–2021) from the population of Alto do Couto, in Serra do Courel, reveal a small effective population size (Ne < 100). E.

Holocentric Chromosomes of Luzula elegans Are Characterized by a Longitudinal Centromere Groove, Chromosome Bending, and a Terminal Nucleolus Organizer Region [PDF]

open access: yes, 2011
The structure of holocentric chromosomes was analyzed in mitotic cells of Luzula elegans. Light and scanning electron microscopy observations provided evidence for the existence of a longitudinal groove along each sister chromatid.

Functional Signatures of Surface Pollen and Vegetation Are Broadly Similar: Good News for Past Reconstructions of Vegetation

open access: yesJournal of Biogeography, Volume 52, Issue 5, May 2025.
ABSTRACT Aim Pollen assemblages are widely used to infer paleoenvironment features, aiming at reconstructing both past climates and biomes. However, the functional link between environmental conditions and pollen assemblages is not straightforward and requires thorough testing to be used confidently.
