Frontiers in Microbiology, 2016 To examine microbe-mineral interactions in subsurface oceanic crust, we evaluated microbial colonization on crustal minerals that were incubated in borehole fluids for one year at the seafloor wellhead of a crustal borehole observatory (IODP Hole U1301A,

Nordic Journal of Botany, EarlyView.This study reports for the first time a checklist of native vascular plants and provides a comprehensive analysis of the flora of the Redberry Lake Biosphere Region (RLBR) in the province of Saskatchewan, Canada. To complete an inventory of the regional flora, I conducted intensive field investigations during 2010–2025 and employed detailed examination

Losers and winners: responses of grassland arthropods to land‐use components
Oikos, EarlyView.Intensified land‐use in grasslands reduces biodiversity, particularly affecting arthropod populations. However, responses of individual species vary depending on their ecological traits and habitat requirements. Some species may tolerate or even benefit from intensive land‐use, while others, particularly specialists or those with narrow niches, are ...

Oikos, EarlyView.Plant traits and their tradeoffs are major determinants of plant functions. Although trait‐based frameworks should apply to plant functioning at any life stage, they have been primarily established for adult plants. Therefore, we lack comprehensive trait‐based studies of seedlings across multiple species to prove which key dimensions of trait variation

Microbial Selection and Survival in Subseafloor Sediment
Frontiers in Microbiology, 2019 Many studies have examined relationships of microorganisms to geochemical zones in subseafloor sediment. However, responses to selective pressure and patterns of community succession with sediment depth have rarely been examined.

Sources of variations in total column carbon dioxide [PDF]
, 2011 Observations of gradients in the total CO_2 column, (CO2), are expected to provide improved constraints on surface fluxes of CO_2. Here we use a general circulation model with a variety of prescribed carbon fluxes to investigate how variations in ...

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species
Oikos, EarlyView.Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...
