Conflicting intersexual mate choices maintain interspecific sexual interactions
Population Ecology - Tập 57 - Trang 261-271 - 2015
Reproductive interference, interspecific sexual interactions that affect
reproductive success, is found in various taxa and has been considered as a
fundamental source of reproductive character displacement (RCD). Once RCD has
occurred, persistent interspecific sexual interactions between species pairs are
expected to diminish. However, reproductive interference has been reported from
some species...
Are there genetically controlled habitat-specific differences in spatial aggregation of drosophilids?
Population Ecology - Tập 46 - Trang 269-274 - 2004
Variation in spatial patterns of competing organisms is of fundamental
importance for community and population processes. Yet the mechanisms
controlling subjects like the degree of spatial aggregation in competing insect
larvae across fragmented resources have rarely been addressed. In the present
study, we tested for systematic differences in the spatial distribution patterns
of Drosophila subobs...
How does spatio-temporal disturbance influence species diversity in a hierarchical competitive system? Prospective order of species coexistence and extinction
Population Ecology - - 2003
To address how habitat destruction and hierarchical competition among species
affect the spatio-temporal dynamics of a multi-species community, we present a
compartment model in which multiple species undergo dispersal and competitive
interactions in a patchy habitat arranged in a two-dimensional lattice. We
assume that disturbances are periodically imposed on some parts of the lattice
in a block,...
Different population responses of three sympatric rodent species to acorn masting—the role of tannin tolerance
Population Ecology - Tập 59 - Trang 29-43 - 2017
Rodent population dynamics are predicted to respond positively to the masting of
acorns, but diverging results have been published. This study tested the
hypothesis that population responses to acorn masting vary depending on
differences in the tolerance to tannins of different rodent species. The effects
of acorn abundance on the rodent population densities were analyzed using a
dataset obtained ...
Dispersal and habitat cuing of Eurasian red squirrels in fragmented habitats
Population Ecology - Tập 52 - Trang 527-536 - 2010
Animal dispersal and subsequent settlement is a key process in the life history
of many organisms, when individuals use demographic and environmental cues to
target post-dispersal habitats where fitness will be highest. To investigate the
hypothesis that environmental disturbance (habitat fragmentation) may alter
these cues, we compared dispersal patterns of 60 red squirrels (Sciurus
vulgaris) in ...
Tiller population dynamics of reciprocally transplanted Eriophorum vaginatum L. ecotypes in a changing climate
Population Ecology - Tập 57 - Trang 117-126 - 2014
Moist tussock tundra, dominated by the sedge Eriophorum vaginatum L., covers
approximately 3.36 × 108 km2 of arctic surface area along with large amounts of
subarctic land area. Eriophorum vaginatum exhibits ecotypic differentiation
along latitudinal gradients in Alaska. While ecotypic differentiation may be
beneficial during periods of climate stability, it may be detrimental as climate
changes, ...
Toads in the backyard: why do invasive cane toads (Rhinella marina) prefer buildings to bushland?
Population Ecology - Tập 58 - Trang 293-302 - 2016
Like many invasive species, cane toads (Rhinella marina) in Australia
concentrate in the disturbed habitats created by human activity, rather than in
pristine areas. We surveyed cane toads in the wet–dry tropics of the Northern
Territory to assess the abundances, body sizes, sexes, behaviour, hydration
state and feeding rates of toads around buildings compared to those in areas
remote from buildin...
Conspecific host discrimination by ovipositing Euphydryas editha butterflies: Its nature and its consequences for offspring survivorship
Population Ecology - Tập 27 Số 1 - Trang 87-98 - 1985
SummaryOvipositing E. editha butterflies display post‐alighting discrimination
among patches of Collinsia torreyi, one of their major hosts in the General's
Highway (GH) population at a montane site in California. Females tended to
accept (i.e. oviposit on) dense patches of this host and to reject sparse
patches. Possible behavioural mechanisms underlying this tendency are discussed.
The consequen...
Density dependence in northern ungulates: interactions with predation and resources
Population Ecology - Tập 51 - Trang 123-132 - 2008
Variation in the abundance of animals has traditionally been explained as the
outcome of endogenous forcing from density dependence and exogenous forcing
arising from variation in weather and predation. Emerging evidence suggests that
the effects of density dependence interact with external influences on
population dynamics. In particular, spatial heterogeneity in resources and the
presence of cap...
