Coefficient shifts in geographical ecology: an empirical evaluation of spatial and non-spatial regression
A major focus of geographical ecology and macroecology is to understand the causes of spatially structured ecological patterns. However, achieving this understanding can be complicated when usingExpand

Successful Removal of German Yellowjackets (Hymenoptera: Vespidae) by Toxic Baiting
Abstract Vespula germanica (F.) is a social vespid that has invaded many parts of the world, including Argentina. This wasp usually becomes a pest, affecting several economic activities. It also mayExpand

Control of Vespula germanica (Hym. Vespidae) populations using toxic baits: bait attractiveness and pesticide efficacy
Abstract:  Our aim was to test a set of baits and pesticides for the control of yellowjacket populations in NW Patagonia (Argentina), through field trials. We tested the attractiveness of proteinExpand

A COMPARATIVE STUDY OF SHINY COWBIRD PARASITISM OF TWO LARGE HOSTS, THE CHALK-BROWED MOCKINGBIRD AND THE RUFOUS-BELLIED THRUSH
Abstract It is usually accepted that generalist brood parasites should avoid using hosts larger than themselves because host chicks may outcompete parasite chicks for food. We studied theExpand

The potential distribution of German wasps (Vespula germanica) in Argentina
Abstract In the early 1980s, the German wasp (Vespula germanica) arrived in Argentina and became established in northern Patagonia. We use an ecoclimatic computer‐based program (CLIMEX) to predictExpand

Effects of pine silviculture on the ant assemblages (Hymenoptera: Formicidae) of the Patagonian steppe
In NW Patagonia, forestry with rapid growing species is an expanding practice, especially in the semi-arid steppe. To provide data for managing forests for biodiversity, we studied the impact ofExpand

The impact of an exotic social wasp (Vespula germanica) on the native arthropod community of north‐west Patagonia, Argentina: an experimental study
Abstract 1. Biological invasions are usually thought to have a negative impact on native communities. However, data supporting this idea are often based on comparative studies between invaded andExpand

The spatial variation in ant species composition and functional groups across the Subantarctic-Patagonian transition zone
The role of ecotones in the maintenance of species diversity is rather controversial; they may represent either biodiversity hotspots with unique and rare forms, or be transitional areas that holdExpand

Effect of fire on ground beetles and ant assemblages along an environmental gradient in NW Patagonia: Does habitat type matter?
ABSTRACT The response of beetle and ant assemblages to fire (2–5 y old) and the dependence of that response on habitat type were analyzed. Using pitfall traps, beetles (Coleoptera) and antsExpand

Competition for food between the exotic wasp Vespula germanica and the native ant assemblage of NW Patagonia: evidence of biotic resistance?
The success of a biological invasion may depend on the interactions between the invader and the native biota. However, little experimental evidence demonstrates whether local species can successfullyExpand
