Variation in density of early stages, that is, larvae and juveniles, is a major determinant of the distribution and abundance of the adult population of most marine invertebrates. These early stages thus play a key role in competitive interactions, and, more specifically, in invasion dynamics when biologically similar native and non-native species (NNS) come into contact in the same habitat. We...

1. The structure of a community is governed by a complex combination of processes whose relative importance varies over time and space. Larval dynamics, settlement and recruitment are thought to be important processes limiting adult abundance and distribution of benthic invertebrates with planktonic larvae. 2. Two invasive molluscs with similar morphology and resource needs, the Eurasian zebra ...

Habitat selection models, such as the ideal free, ideal despotic, site-dependent, and conspecific cuing models, are of great importance to behavioral ecologists given their capability to predict habitat distributions and to link individual behavior to population processes. However, there have been relatively few field tests of their predictions. We tested the 4 models by studying the process of...

Scholars have frequently mentioned the link between a group’s settlement pattern and its involvement in violent conflict. In this paper, I develop a computational model to examine this relationship in detail. I argue that the settlement pattern of a group has an impact on group mobilization, because it determines how quickly mobilization can spread from a few extremists to the entire group popu...

Spanish ship Santa María ground to a halt on a coral reef off the coast of an island known to its Taíno inhabitants as Ayiti. The loss of don Cristóbal Colón’s flagship forced him to leave a contingent of thirty-nine crewmembers behind to construct a fortified settlement they dubbed Villa de la Navidad, while the admiral and the rest of his fleet departed to report to their sovereign patrons in...

EuroAmerican land use and its legacies have transformed forest structure and composition across the United States (US). More accurate reconstructions of historical states are critical to understanding the processes governing past, current, and future forest dynamics. Gridded (8x8km) estimates of pre-settlement (1800s) forests from the upper Midwestern US (Minnesota, Wisconsin, and most of Michi...
