Holocene fire regimes, fire‐related plant functional types, and climate in south‐coastal British Columbia forests

open access: yesEcosphere, 2023
Paleoecological records of past fire events and forest composition provide long‐term ecological context for modern changes in fire regimes and forest dynamics. Here, we use pollen and contiguous macroscopic charcoal analyses of lake sediments from Pender

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1270-1285, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, Volume 68, Issue S2, Page S47-S68, May 2026.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Evidence for elevated emissions from high-latitude wetlands contributing to high atmospheric CH4 concentration in the early Holocene [PDF]

open access: yes, 2013
The major increase in atmospheric methane (CH4) concentration during the last glacial-interglacial transition provides a useful example for understanding the interactions and feedbacks among Earth\u27s climate, biosphere carbon cycling, and atmospheric ...

Trends in Endoscopist Reporting Rates of Eosinophilic Gastrointestinal Diseases in Japan Evaluated by the Japan Endoscopy Database Project

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
We analyzed 9,940,870 endoscopic procedures from the Japanese Endoscopy Database (2015–2023), identifying 9,669 eosinophilic gastrointestinal disease (EGID) cases. The prevalence of eosinophilic esophagitis, gastritis, and duodenitis increased significantly (p < 0.001), while enteritis and colitis remained unchanged (p = 0.136). EoE rose from 36 cases (

Rapid Surveys Reveal Temporal Variation in Flowering Community Phenology in a Great Basin Desert Ecosystem

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Across four years of surveys in an arid Great Basin ecosystem, community flowering phenology showed strong seasonal, interannual, and trait‐based variation, with most differences occurring in spring and little variation in fall. Flowering patterns broadly corresponded with interannual climate variability, consistent with the importance of moisture ...

Airborne pollen calendar of Lublin, Poland.

open access: yesAnnals of agricultural and environmental medicine : AAEM, 2004
Pollen concentration in the atmosphere of Lublin (eastern Poland) was studied by means of volumetric method using Hirst sampler (VPPS 2000, Lanzoni) in 2001-2002. The pollen trap was mounted at the height of 15 m in the centre of Lublin. On the basis of analysis of mean daily values of pollen concentration, the pollen calendar was constructed for 16 ...
