Faster growing and more functionally diverse: global change alters functional trait composition of mountain plant communities in the European Alps

open access: yesEcography, EarlyView.
Understanding how global change reshapes mountain plant communities is essential for predicting biodiversity and ecosystem function in a warming world. Using resurvey data from over 1400 non‐forest vegetation plots across the European Alps, we show that community‐weighted means of key functional traits capturing important dimensions of plant ecological

Global analysis suggests nitrogen deposition as an underestimated driver of vegetation greening

open access: yesEcography, EarlyView.
The local effects of atmospheric nitrogen deposition on plants are well established, yet a global empirical analysis of nitrogen deposition effects on vegetation dynamics is missing. Here, we assess how nitrogen deposition, alongside other global change drivers such as fire, and changes in temperature, precipitation and human land use, is related to ...

The dual influence of top‐down and bottom‐up processes on a mesopredator and the consequences for prey

open access: yesEcography, EarlyView.
Ecosystem dynamics are shaped by interacting top‐down and bottom‐up processes, yet their relative importance may vary through time following disturbances such as disease outbreaks and changes in apex predator communities. Using a 52‐year time series in south‐central Sweden, we examined how disease, apex predators, and prey availability jointly impact a

A creep model for high-density snow [PDF]

open access: yes, 2017
Abstract : This effort modifies Mellor and Smiths creep model for dense snow to conform to the more general creep power law form (Glens creep law for ice is a special case of this power law). The present study used this general form as the basis for developing two creep models: one to describe the primary creep and another that models secondary creep ...

Civil Society Advocacy and Climate Change in Kenya: The Question of “Local Voices” and Their “Amplification”

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

Spatial Variability of Snow Water Equivalent – The Case Study from the Research Site in Khibiny Mountains, Russia

open access: yesJournal of Hydrology and Hydromechanics, 2019
The aim of the investigation was assessment of spatial variability of the characteristics of snowpack, including the snow water equivalent (SWE) as the main hydrological characteristic of a seasonal snow cover.

Seismic Response of Existing Masonry‐Infilled RC Frame Structures Retrofitted with Steel Exoskeletons

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Potential for conflict between urban coyotes and people experiencing unsheltered homelessness

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Across North America, both unsheltered homelessness and human–coyote (Canis latrans) conflict are increasing, but the relationship between these phenomena has not been thoroughly explored. We synthesize literature‐based evidence with anecdotal observations that occurred during a 15‐year study of coyotes in Edmonton, Canada, to describe three likely ...

Status of the snow leopard Panthera uncia in the Qilian Mountains, Gansu Province, China

open access: yesOryx
Population density estimation is integral to the effective conservation and management of wildlife. The snow leopard Panthera uncia is categorized as Vulnerable on the IUCN Red List, and reliable information on its density is a prerequisite for its ...
