Identifying Key Environmental Drivers of Reach‐Scale Salmonid eDNA Recovery With Random Forest

open access: yesEnvironmental DNA
Environmental DNA (eDNA) sampling from rivers has emerged as a promising new method for monitoring freshwater organisms of management concern. However, eDNA sampling cannot yet offer reliable estimates of a target species' abundance/biomass or confident ...

Ionic Liquid-Catalyzed CO2 Conversion for Valuable Chemicals

open access: yesMolecules
CO2 is not only the main gas that causes the greenhouse effect but also a resource with abundant reserves, low price, and low toxicity. It is expected to become an important “carbon source” to replace oil and natural gas in the future.

Finding Stars: Mapping the Geography of the World's Scientific Elites

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract Scientific excellence is clustering ever more tightly in a few ‘superstar’ cities. Four—New York, Boston, London and the San Francisco Bay Area—now host 12% of the world's top scientists. In contrast, the Global South remains largely absent, with the notable exception of Beijing's dramatic rise.

Effects of Seeding Pattern and Cultivar on Productivity of Baby Spinach (Spinacia oleracea) Grown Hydroponically in Deep-Water Culture

open access: yesHorticulturae, 2019
Baby spinach (Spinacia oleracea) was grown in a bench-scale deep-water culture (DWC) system in expanded polystyrene (EPS) plug trays. Two experiments were performed. In the first, different seeding patterns, [1-2-1-2…] or [3-0-3-0…] seeds per

An in‐house nucleic acid test for detection of Anaplasma phagocytophilum in whole blood donor samples

open access: yesTransfusion, EarlyView.
Abstract Background Anaplasma phagocytophilum is a tick‐borne pathogen that causes anaplasmosis. Increased incidences of this disease in Canada and cases of transfusion‐transmitted anaplasmosis in the United States have been reported. Currently, there are no Health Canada licensed methodologies available for detection of A.

Seasideness: Sense of Place at a Seaside Resort [PDF]

open access: yes, 2015
British seaside resorts are associated with the birth of mass tourism and are amongst the most significant leisure spaces since industrialization. Despite sliding down the expanding leisure ‘consumption spaces hierarchy’ within the later decades of the 20th century (Urry 1997:104), they are still significant leisure resources and are a durable element ...

Modeling maize growth and development in temperate and tropical agro‐climatic systems using MAIZSIM

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract MAIZSIM is a mechanistic maize (Zea mays L.) crop model with a two‐dimensional finite element‐based soil simulator, known for its detailed process‐based representation and minimal calibration requirements. While the model has been extensively applied in temperate agro‐climatic systems, its use in tropical areas has not been explored.

Salted Peat: The Forgotten Casualty of Rising Sea Level in Freshwater Coastal Tropical Peatlands

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
This paper invites reflection on the largely overlooked risk that rising sea levels may salinize coastal tropical peatlands, potentially destabilizing vegetation, carbon cycling, and livelihoods. By synthesizing emerging evidence, it highlights a critical blind spot in climate models and adaptation frameworks that warrant urgent scientific and policy ...
