Environmental gradients and the structure of freshwater snail communities
A fundamental goal of ecology is to understand the factors that influence community structure and, consequently, generate heterogeneity in species richness across habitats. While niche-assembly (e.g.Expand

Metacommunity patterns in larval odonates
The growth of metacommunity ecology as a subdiscipline has increased interest in how processes at different spatial scales structure communities. However, there is still a significant knowledge gapExpand

Dispersal, niche breadth and population extinction: colonization ratios predict range size in North American dragonflies.
Species' range sizes are shaped by fundamental differences in species' ecological and evolutionary characteristics, and understanding the mechanisms determining range size can shed light on theExpand

Preserving prairies: understanding temporal and spatial patterns of invasive annual bromes in the Northern Great Plains
Two Eurasian invasive annual brome grasses, cheatgrass (Bromus tectorum) and Japanese brome (Bromus japonicus), are well known for their impact in steppe ecosystems of the western United States whereExpand

Predator induction of spine length in larval Leucorrhinia intacta (Odonata)
Questions: Do larvae of a dragonfly with a broad habitat distribution have longer abdominal spines when they co-exist with fish, and are these differences the result of phenotypic plasticity?Expand

Solar cycle 24: what is the Sun up to?
March 2012 brought the first solar and geomagnetic disturbances of any note during solar cycle 24. But perhaps what was most remarkable about these events was how unremarkable they were compared toExpand

Reconstruction of geomagnetic activity and near-Earth interplanetary conditions over the past 167 yr - Part 1: A new geomagnetic data composite
Abstract. We present a new composite of geomagnetic activity which is designed to be as homogeneous in its construction as possible. This is done by only combining data that, by virtue of theExpand

Cross-Scale Interactions and the Distribution-Abundance Relationship
Positive interspecific relationships between local abundance and extent of regional distribution are among the most ubiquitous patterns in ecology. Although multiple hypotheses have been proposed,Expand

A hump-shaped relationship between isolation and abundance of Notonecta irrorata colonists in aquatic mesocosms.
We examined the relationship between the isolation of experimental aquatic mesocosms and the abundance of an aquatic insect colonist, Notonecta irrorata, over two years. We used a curve-fittingExpand
