Climate change is expected to increase the extent and severity of wildfires throughout the boreal forest. Historically, black spruce (Picea mariana (Mill.) B.S.P.) forests in interior Alaska have been relatively free of non-native species, but the compounding effects of climate change and an...

The invasion of wetlands by Phragmites australis is a conservation concern across North America. We used the invasion of Chesapeake Bay wetlands by P. australis as a model system to examine the effects of regional and local stressors on plant invasions. We summarized digital maps of the...

Flowering of bamboos is rare, it tends to be sporadic when some culms flower or gregarious, when all the individuals in the population flower at the same time and in different areas. Some species of woody bamboos die after flowering while others do not. Chusquea scandens Kunth is a woody bamboo...

Woody nitrogen (N) fixers are known to fix atmospheric N at very high rates. However, N leached from woody N fixers is rarely accounted for in catchment nutrient budgets. We conducted a scoping study to determine the potential impact of the invasive N fixer gorse (Ulex europaeus) on water quality...

Groenlandia densa (L.) Fourr ranks as critically endangered in Poland. It was noted sporadically until 1987 but has not been confirmed more recently. For this reason, reintroduction of this species to Pomeranian waters (N Poland) from its remaining populations in northern Germany has been planned....

Many efforts to restore disturbed landscapes seek to meet ecological goals over timescales from decades to centuries. It is thus crucial to know how different actions available to restoration practitioners may affect ecosystems in the long term, yet few such data exist. Here, we test the effects of ...

Introduced plants are often identified as the major conservation concern worldwide, however, they also may offer conservation benefits, among others, provide habitat and/or food resources to protected animals. Here we aimed to assess the ability of the great Capricorn beetle Cerambyx cerdo, a...

The interplay between the invasion of alien plant species and re-colonization of native plant species is important for conservation. Sandy coastal plains (called restinga in Brazil) were used as a model system to explore the abiotic barriers that potentially limit the initial establishment of alien ...

Common buckthorn (Rhamnus cathartica L.) is one of the most abundant and ecologically harmful non-native plants in forests of the Upper Midwest United States. At the same time, European earthworms are invading previously glaciated areas in this region, with largely anecdotal evidence suggesting...

Theory suggests that species with different traits will respond differently to landscape fragmentation. Studies have shown that the presence of species in fragments of varying size, shape and connectivity is dependent on plant traits related to dispersal ability, persistence and disturbance...
