1. The spread and intensification of agriculture are recognized as two of the most important global threats to wildlife. There are clear links between agricultural change and declines in biodiversity across a wide range of agricultural systems, and…

The effects of hybridization on the abundance of parental taxa depends on their relative frequency, the viability of hybrid offspring and the degree of ecological differentiation among parental and hybrid taxa. Habitat overlap can facilitate…

Habitat fragmentation is the transformation of once-extensive landscapes into smaller, isolated remnants surrounded by new types of habitat. There is ample evidence of impoverished biodiversity as a consequence of habitat fragmentation, but its most…

The loss and fragmentation of habitat is a major threat to the continued survival of many species. We argue that, by including spatial professes in restoration management plans, the effects of habitat loss and fragmentation can be offset. Yet few…

Brachycome muelleri Sonder (Corunna daisy) is an endangered annual herb, endemic to the upper Eyre Peninsula of South Australia. It is restricted to a single population occupying an area of approximately 3 ha on steep, south-facing cliff-foot slopes…

1. Theory and empirical evidence suggest that community invasibility is influenced by propagule pressure, physical stress and biotic resistance from resident species. We studied patterns of exotic and native species richness across the Flooding…

Assessment of habitat use for species of conservation concern can lead to important measures for habitat conservation. In high-Andean Polylepis forests (3000-5000 m), two such species are the Giant Conebill (Oreomanes fraseri) and the Tawny Tit…

This book describes ggplot2, a new data visualization package for R that uses the insights from Leland Wilkisons Grammar of Graphics to create a powerful and flexible system for creating data graphics. With ggplot2, its easy to: produce handsome,…

Oxidation of aqueous bromide into reactive, gas-phase bromine species has been of interest since the 1980s, when the presence of bromine in the Arctic boundary layer was linked to ozone depletion events. We have investigated two different mechanisms…
-
Box model studies have been performed to study the role of aqueous phase chemistry with regard to halogen activation for marine and urban clouds and the marine aerosol as well. Different chemical pathways leading to halogen activation in diluted…

September 11 has changed the way people think about airport, aviation, and security in general. The threat is expanding interest in more reliable systems to detect presence of people within the protected perimeters. The occupancy sensors detect the…

With the Clean Air Acts and increased environmental consciousness, many engineers, consulting companies, planners, and meteorologists find themselves pro- pelled into the work of calculating atmospheric diffusion. Many of these people are not…

Current data models for representing geospatial data are decades old and well developed, but suffer from two major flaws. First, they employ a one- size-fits-all approach, in which no connection is made between the charac- teristics of data and the…

The concept of Gaia, a self-regulating Earth, excites both admiration and obloquy. Its inventor (or rather re-discoverer) describes the genesis and evolution of the hypothesis.

The Lomb periodogram and discrete Fourier transform are described and applied to harmonic analysis of two typical data sets, one air quality time series and one water quality time series. The air quality data is a 13 year series of 24 hour average…

Harvest index (HI) is one of the indices currently used to evaluate a crops partitioning efficiency. The objective of this three years study was to determine how the HI of maize. (Zea mays) was affected by changes in population density, genotype and…

Social demands related to native forest ecosystems are based on an efficient management, with a balance between conservation and timber production. This paper describes the industry adaptation to a biodiversity program with an alternative…
