Partitioning the variation among spatial, temporal and environmental components in a multivariate data set
Wiley - Tập 23 Số 2 - Trang 158-167 - 1998
Marti J. Anderson, N. A. Cribble
Abstract We propose a method of partitioning the variation in a multivariate set of data according to (i) environmental variables, (ii) variables describing the spatial structure in the data and (iii) temporal variables. This method is an extension of an existing method for partialling out the spatial component of environmental variation, using canonical analysis. Ou...... hiện toàn bộ
Ecology of benthic macro‐invertebrates in soft‐sediment environments: A review of progress towards quantitative models and predictions
Wiley - Tập 24 Số 4 - Trang 452-476 - 1999
Andrew Constable
AbstractThis paper reviews the ecology of soft‐sediment macro‐invertebrates and, in particular, evaluates how much progress has been made in the recent literature towards elaborating statistical models of the ecology of these biota and in using quantitative predictions derived from these models. Steps to formulating statistical models on the dynamics of populations...... hiện toàn bộ
Role of meiofauna in estuarine soft‐bottom habitats*
Wiley - Tập 24 Số 4 - Trang 327-343 - 1999
Bruce C. Coull
Meiofauna are ubiquitous in estuaries worldwide averaging 106 m−2. Abundance and species composition are controlled primarily by three physical factors: sediment particle size, temperature and salinity. While meiofauna are integral parts of estuarine food webs, the evidence that they are biologically controlled is equivocal. Top down (predation) co...... hiện toàn bộ
Characteristics of the ichthyofaunas of southwestern Australian estuaries, including comparisons with holarctic estuaries and estuaries elsewhere in temperate Australia: A review
Wiley - Tập 24 Số 4 - Trang 395-421 - 1999
I. C. Potter, Glenn A. Hyndes
Data on the species compositions and the ages, sizes, reproductive biology, habitats and diets of the main species in the ichthyofaunas of seven estuaries in temperate southwestern Australia have been collated. Twenty‐two species spawn in these estuaries, of which 21 complete their lifecycles in the estuary. The latter group, which includes several species of atherinids and gobies with sho...... hiện toàn bộ
Interrelationships among some ectomycorrhizal trees, hypogeous fungi and small mammals: Western Australian and northwestern American parallels
Wiley - Tập 12 Số 1 - Trang 53-55 - 1987
N. Malajczuk, James M. Trappe, Randy Molina
Abstract Species of the hypogeous fungus genus. Mesophellia have been shown to form ectomycorrhiza with Eucalyptus diversicolor and improve seedling growth. Since the morphology of these fungi increases their dependence on animal mycophagy for spore dispersal, these results imply a tripartite interr...... hiện toàn bộ
Insect herbivory on mangrove leaves in North Queensland*
Wiley - Tập 12 Số 1 - Trang 1-7 - 1987
A. I. Robertson, Norman C. Duke
AbstractEstimates of leaf damage by insect herbivores are presented for 25 species of mangrove plants, comprising canopy and understorey species. Leaf area loss was highly variable among the species sampled, with means ranging from 0.3 to 35.0% of expanded leaf area. There was also great variability amongst leaves within species, and the mean coefficient of variati...... hiện toàn bộ
Non‐parametric multivariate analyses of changes in community structure
Wiley - Tập 18 Số 1 - Trang 117-143 - 1993
K.R. Clarke
Abstract In the early 1980s, a strategy for graphical representation of multivariate (multi‐species) abundance data was introduced into marine ecology by, among others, Field, et al. (1982). A decade on, it is instructive to: (i) identify which elements of this often‐quoted strategy have proved most useful in practical assessment of c...... hiện toàn bộ
Quantifying observer heterogeneity in bird counts
Wiley - Tập 24 Số 3 - Trang 270-277 - 1999
Ross B. Cunningham, David B. Lindenmayer, H. A. Nix, Bruce D. Lindenmayer
An essential pilot study was designed to quantify observer heterogeneity and to compare observation methods for the detectability of forest birds in stands of Eucalyptus and Pinus radiata forest as a basis for a major research project on habitat fragmentation near Tumut, southern New South Wales. Twelve experienced observers participate...... hiện toàn bộ
Taxonomy of estuarine invertebrates in Australia
Wiley - Tập 24 Số 4 - Trang 381-394 - 1999
Pat Hutchings
An Australian estuary is primarily a marine‐dominated environment, subjected to major salinity changes only after heavy rains and during flood conditions. In southeastern Australia estuarine biota are similar to those in shallow coastal bays and some of the coastal lagoons, and most taxonomic studies on estuarine fauna have occurred in this region. Several major surveys of estuarine and co...... hiện toàn bộ
The effect of supplementary food on home range of the southern brown bandicoot, Isoodon obesulus (Marsupialia: Peramelidae)
Wiley - Tập 16 Số 1 - Trang 71-78 - 1991
S. K. Broughton, Chris R. Dickman
AbstractThe study investigated the relationship between home range and food abundance in a population of the southern brown bandicoot. Isoodon obesulus, in Western Australia. Home range areas were estimated seven times between 1986 and 1988 by live‐trapping, spool‐and‐line devices and fluorescent pigment tracking. The abundance of inverte...... hiện toàn bộ
