Partitioning the variation among spatial, temporal and environmental components in a multivariate data set
Wiley - Tập 23 Số 2 - Trang 158-167 - 1998
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. Our proposed method extends
this ...
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
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 and assemblages
are discussed. C...
Role of meiofauna in estuarine soft‐bottom habitats*
Wiley - Tập 24 Số 4 - Trang 327-343 - 1999
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) control clearly does not regulate meiofaunal
assembl...
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
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 short
lifec...
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
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
interrelationship between eucalypts, hypogeous fungi and marsupials which
parallels the North American int...
Insect herbivory on mangrove leaves in North Queensland*
Wiley - Tập 12 Số 1 - Trang 1-7 - 1987
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 variation for leaf loss from the 25
spec...
Non‐parametric multivariate analyses of changes in community structure
Wiley - Tập 18 Số 1 - Trang 117-143 - 1993
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 community change resulting from pollution impact; and
(ii) ask to...
Quantifying observer heterogeneity in bird counts
Wiley - Tập 24 Số 3 - Trang 270-277 - 1999
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 participated in the investigation. Point interval counts, zig‐zag
walks a...
Taxonomy of estuarine invertebrates in Australia
Wiley - Tập 24 Số 4 - Trang 381-394 - 1999
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
coastal ba...
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
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 invertebrate food was measured simultaneously by placing
pitfall tr...
