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

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.

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-

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

Comparison of species richness of light trap-collected caddisfly assemblages (Insecta: Trichoptera) using rarefaction [PDF]
, 2002 ConselVation value of light trap-collected caddisfly assemblages(Insecta: Trichoptera) was evaluated on the basis of their species richness. The assemblage coming from an artificial stream showed a higher conservation value based on species richness than

Determinants of species richness patterns in the Netherlands across multiple taxonomic groups [PDF]
, 2009 We examined the species richness patterns of five different species groups (mosses, reptiles and amphibians, grasshoppers and crickets, dragonflies, and hoverflies) in the Netherlands (41,500 km2) using sampling units of 5 × 5 km. We compared the spatial

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.
