A century of tree line changes in sub-Arctic Sweden shows local and regional variability and only a minor influence of 20th century climate warming [PDF]

open access: yes, 2011
Aim Models project that climate warming will cause the tree line to move to higher elevations in alpine areas and more northerly latitudes in Arctic environments.

Regional patterns and controlling factors in plant species composition and diversity in Canadian lowland coastal bogs and laggs [PDF]

open access: yesMires and Peat, 2016
Inventories of natural assemblages of plant species are critical when planning ecological restoration of bogs. However, little is known about the regional variation in plant communities at the margins (laggs) of bogs, even though they are an integral ...

The biodiversity audit approach challenges regional priorities and identifies a mismatch in conservation [PDF]

open access: yes, 2012
1. Despite a strong uptake of evidence-based approaches, conservation often proceeds from a grossly incomplete understanding of species priorities. To optimize conservation impact within a biogeographical region, quantitative knowledge is needed of the ...

Genotype-environment associations support a mosaic hybrid zone between two tidal marsh birds [PDF]

open access: yes, 2015
Local environmental features can shape hybrid zone dynamics when hybrids are bounded by ecotones or when patchily distributed habitat types lead to a corresponding mosaic of genotypes.

Spatial distribution and influencing factors of settlements in the farming–pastoral ecotone of Inner Mongolia, China

open access: yesEcosystem Health and Sustainability, 2020
Rural settlements serve as an important part of the rural landscape, and environmental conditions influence their spatial distribution. We hypothesize that there are variations in the spatial patterns of settlements across different farming–pastoral ...

Dramatic Increases of Soil Microbial Functional Gene Diversity at the Treeline Ecotone of Changbai Mountain. [PDF]

open access: yes, 2016
The elevational and latitudinal diversity patterns of microbial taxa have attracted great attention in the past decade. Recently, the distribution of functional attributes has been in the spotlight.

Human activities accelerated the degradation of saline seepweed red beaches by amplifying top‐down and bottom‐up forces [PDF]

open access: yes, 2018
Salt marshes dominated by saline seepweed (Suaeda heteroptera) provide important ecosystem services such as sequestering carbon (blue carbon), maintaining healthy fisheries, and protecting shorelines. These salt marshes also constitute stunning red beach

Seascape ecology in the vicinity of a Blake Ridge cold seep

open access: yesFrontiers in Marine Science, 2023
Systematic surveys of the distribution of epibenthic megafaunal species relative to one another and to environmental variables in the deep sea can lead to inferences and testable hypotheses regarding factors that influence their distributions.

Comparing Physical Collection and Environmental DNA Methods for Determining Abundance Patterns of Gammarus Species along an Estuarine Gradient

open access: yesDiversity, 2023
Estuaries are productive systems with rapid changes in natural stressors, such as salinity, that make perturbation detection challenging. Amphipods are vital to estuarine assemblages and may serve as anthropogenic stress indicators.
