1. Invasive species are present worldwide, yet predicting which invasive species will become problematic in which ecosystems remains an important ecological challenge. Floodplains are at particular risk for invasion, especially when subjected to anthropogenic disturbance. 2. We examined how components of flood regime, habitat quality and habitat configuration influenced the presence and abundan...

A series of models of the lunar interior are derived from topographic, gravitational, librational, and seismic data. The librational parameters and low-degree gravity harmonics result primarily from surface height variations and only secondarily from lateral density variations. The moon departs from isostasy, even-for the low-degree harmonics, with a maximum superisostatic stress of 200 bars un...

From April 1997 through April 1998, 128 raccoons (Procyon lotor (Linnaeus)) collected from 7 sites representing 4 physiographic areas in South Carolina were examined for gastrointestinal helminth parasites. Four species of nematodes (Gnathostoma procyonis (Chandler), Physaloptera rara Hall and Wigdor, Arthrocephahis lotoris (Schwartz), and Molineus barhatus Chandler) and 2 species of acanthocep...

Slope instability in the Butterfly Biosphere Reserve (RBMM) Michoacán, Mexico, is a widespread phenomenon that results from complex interaction among different factors such as climate, slope, and spatial distribution of rock units. The climate temperate subhumid, with rains summer an annual average rainfall 700 to 1250 mm. main physiographic units area are volcanic mountains, slopes greater tha...

In Brazil, research related to the occurrence and prevention of debris flows is incipient when compared extent impacts caused by phenomena. There a need for further studies that consider susceptibility hazard, especially in areas are environmentally socioeconomically vulnerable. This study aimed at assessing debris-flow hazard Rio das Pedras watershed, Cubatão (State São Paulo, Brazil), based o...
