Fire Effects on Understory Forest Regeneration in Southern Amazonia

Frontiers in Forests and Global Change, 2020
Fire in tropical forests increases tree mortality, degrades forest structure, and reduces carbon stocks. Currently, there are large gaps in understanding how fire affects understory forest structure and composition, interactions with fire recurrence, and

Does residence time affect responses of alien species richness to environmental and spatial processes? [PDF]

, 2012
One of the most robust emerging generalisations in invasion biology is that the probability of invasion increases with the time since introduction (residence time). We analysed the spatial distribution of alien vascular plant species in a region of north-

Do the Rich Vote Conservative Because They Are Rich? [PDF]

Review of Economics and Institutions, 2010
Political economics predicts that the rich oppose redistribution and vote for conservative parties. Although this seemingly fits the data well in most countries, I show that the relationship breaks down when we control for unobservable characteristics. Using Norwegian survey data, I study to what extent voting is caused by income.

How do biodiversity patterns of river animals emerge from the distributions of common and rare species? [PDF]

, 2008
We studied the patterns of commonness and rarity for one vertebrate (fish) and four freshwater insect taxa (Ephemeroptera, Plecoptera, Trichoptera and Coleoptera) in southwestern France (57,000 km²), and we analysed the relationships between the location

Richness of species and growth‐forms within sclerophyll and mesophyll vegetation in eastern Australia [PDF]

, 1998
[Abstract]: The patterns in total species richness and in the richness of the dominant growth-forms of vegetation communities of coastal sclerophyll and mesophyll vegetation in eastern Australia are examined.

Determinants of species richness in the Park Grass experiment [PDF]

, 2005
The Park Grass Experiment at Rothamsted in southeast England was started in 1856, making it the longest-running experiment in plant ecology anywhere in the world.

Impact of land-use changes on ant communities and the retention of ecosystem services in Rashad District, Southern Kordofan, Sudan

South African Journal of Science, 2022
The ecological consequences of biodiversity loss are usually the reduction of ecosystem functions. These responses, however, differ depending on the type of land-use change and the ecological setting.
