A new method for non‐parametric multivariate analysis of variance
Austral Ecology - Tập 26 Số 1 - Trang 32-46 - 2001
Marti J. Anderson
AbstractHypothesis‐testing methods for multivariate data are needed to make rigorous probability statements about the effects of factors and their interactions in experiments. Analysis of variance is particularly powerful for the analysis of univariate data. The traditional multivariate analogues, however, are too stringent in their assumptions for most ecological multivariate data sets. Non‐param... hiện toàn bộ
Mixed hummingbird: Long‐proboscid‐fly pollination in ‘ornithophilous’Embothrium coccineum (Proteaceae) along a rainfall gradient in Patagonia, Argentina
Austral Ecology - Tập 31 Số 4 - Trang 512-519 - 2006
Mariano Devoto, Norberto H. Montaldo, Diego Medán
Abstract  The pollination ecology of eight populations of the tree Embothrium coccineum was studied along a steep rainfall gradient in NW Patagonia, Argentina. The showy red flowers suggest an ornithophilous pollination syndrome and they have been reported to attract hummingbirds in Argentina and hummingbirds and passerines in Chile. At each population, flower visitors were recorded and floral rew... hiện toàn bộ
Effects of long‐term fox baiting on species composition and abundance in an Australian lizard community
Austral Ecology - Tập 30 Số 8 - Trang 899-905 - 2005
Mats Olsson, Erik Wapstra, Gerry Swan, ERN SNAITH, Ronald J. Clarke, Thomas Madsen
Abstract  We report on the effects of almost a decade of 1080‐fox baiting on a lizard community in a mosaic Australian habitat. Replicated comparisons of baited versus non‐baited control areas with near‐identical histories of bush fires, grazing and climate showed a higher density of red fox tracks (Canis vulpes) in the non‐baited areas. Furthermore, the fox‐baited areas showed a more than five ti... hiện toàn bộ
Importance of matrix permeability and quantity of core habitat for persistence of a threatened saltmarsh bird
Austral Ecology - Tập 38 Số 3 - Trang 326-337 - 2013
Michael B. Ashcroft, Richard E. Major
AbstractSpecies habitat preferences can be obscured when individuals have been recorded in non‐core habitats because of dispersal, spillover effects or spatial errors in observation locations. Disentangling the direct effects of the habitats species are observed in from the effects of proximity to other nearby habitats is especially challenging in fragmented landscapes, as many fragmentation metri... hiện toàn bộ
Vegetation indicators of salinity in northern Queensland
Austral Ecology - Tập 28 Số 5 - Trang 539-552 - 2003
Elisabeth N. Bui, Brent Henderson
Abstract The possibility that plants could serve as indicators of underlying soil salinity in northern Queensland, Australia, was investigated using 2197 site observations recorded during a land resources inventory of the Dalrymple Shire. The area surveyed intersects three biogeographical regions: the desert uplands, the Einasleigh uplands and the northern brigalow belt. The three dominant plant s... hiện toàn bộ
Interactions between native and invasive gecko lizards in tropical Australia
Austral Ecology - Tập 37 Số 5 - Trang 592-599 - 2012
Daode Yang, Edna González‐Bernal, Matthew Greenlees, Richard Shine
AbstractInvasive geckos of the genus Hemidactylus (Gekkonidae) are spreading rapidly through urban environments in many tropical and subtropical parts of the world. The invaders have caused rapid declines in native gecko abundance in some areas, but their interactions with Australian native species remain unknown. In a small rural village near Darwin, we found that Hemidactylus frenatus is abundan... hiện toàn bộ
Drivers of collapse of fire‐killed trees
Austral Ecology - Tập 48 Số 1 - Trang 134-142 - 2023
David B. Lindenmayer, Lachlan McBurney, Wade Blanchard
AbstractLarge quantities of dead wood can be generated by disturbances such as wildfires. Dead trees created by disturbances play many critical ecological roles in forest ecosystems globally. The ability of deadwood to serve its ecological roles is contingent, in part, on the length of time trees remain standing following disturbance. Here, we briefly outline the results of a 10‐year study that ai... hiện toàn bộ
What factors influence the occurrence and abundance of midstorey Acacia in Mountain Ash forests?
Austral Ecology - Tập 46 Số 4 - Trang 532-544 - 2021
David B. Lindenmayer, Wade Blanchard, Lachlan McBurney, Kita R. Ashman, Elle Bowd, David Blair
AbstractThe midstorey is a critical structural component of many forests globally. Using statistical models, we quantified the influence of two sets of variables on the percentage cover and basal area of two dominant Acacia spp. (Montane Wattle [Acacia frigescens] and Silver Wattle [Acacia dealbata]) in the midstorey of Mountain Ash (Eucalyptus regnans) forests in mainland south‐eastern Australia.... hiện toàn bộ
A seven‐year study of the response of woodland birds to a large‐scale wildfire and the role of proximity to unburnt habitat
Austral Ecology - Tập 46 Số 7 - Trang 1138-1155 - 2021
Michael J. Murphy, Hugh Jones, Terry Koen
AbstractFire is a major ecological driver in many Australian ecosystems, and large‐scale wildfires can impact on faunal assemblages at a landscape scale. Monitoring the response of the avian community and individual bird species following a 92 039 ha wildfire in the Pilliga Forest, in temperate inland south‐eastern Australia, showed an initial decline in species richness and changes in community c... hiện toàn bộ
Small mammal succession is determined by vegetation density rather than time elapsed since disturbance
Austral Ecology - Tập 25 Số 6 - Trang 580-587 - 2000
Vaughan Monamy, Barry J. Fox
Abstract We examined post‐fire responses of two sympatric Australian rodents, Pseudomys gracilicaudatus and Rattus lutreolus, as coastal wet heath regenerated following two high intensity wildfires. Pseudomys gracilicaudatus, an early serai‐stage species, recolonized an area burnt in August 1974 after one year, but took only 3 months to recolonize another area following a wildfire in October 1994.... hiện toàn bộ
