Gonzalez, A., Lawton, J. H., Gilbert, F. S., Blackburn, T. M. & Evans-Freke, I. Metapopulation dynamics, abundance, and distribution in a microecosystem.
This study was designed to test the hypothesis that population dynamics (abundance, breeding condition, and survival) of northern flying squirrels (Glaucomys sabrinus) and red squirrels (Tamiasciurus hudsonicus) would be maintained at levels recorded in old-growth forests by large-scale pre-commercial thinning of young (17 27 years old) lodgepole pine (Pinus contorta) forests.
However, to differentiate impacts associated with introduced diseases from those of climate or other factors that may influence population dynamics, abundance data before and after potential introductions are required (Hochachka and Dhondt 2000; Daszak et al. 2005; Lips et al. 2006; LaDeau et al. 2007).
However, by improving the design and analyses of future studies, we can substantially increase our ability to predict changes in plant population dynamics, abundances and distributions in response to changes in specific environmental drivers.
Pereira e Silva, M. C., Schloter-Hai, B., Schloter, M., van Elsas, J. D. & Salles, J. F. Temporal dynamics of abundance and composition of nitrogen-fixing communities across agricultural soils.
Live, they have everything: the songs, power, shifting dynamics, an abundance of stage presence, and that most elusive quality of all in rock: flawless musicianship.
This study used the LANDIS model to evaluate the effects of fire suppression and reforestation on fire dynamics, species abundance, and age structure of two main species (larch (Larix gmelinii) and white birch (Betula platyphylla)) in Tuqiang Forest Bureau on the northern slopes of Great Hing'an Mountains after a catastrophic fire in 1987.
This study investigated how crop type and crop succession influence the distribution and the dynamics of abundance of two dominant carabid beetle species (Poecilus cupreus and Brachinus sclopeta) at two critical stages of their life cycle: the spring reproductive and overwintering periods.
Understanding the mechanistic relationship between community dynamics, pathogen abundance and behavior, and the host immune response is crucial to further extending the lifespan of this patient population.
All of these parameters involve snail life stages, highlighting the importance of the intermediate host in determining the dynamics and abundance of schistosomes, suggesting that control methods that target the snails will prove highly effective at increased ambient temperatures.
All sampling to date has generally been descriptive; the lack of standardized time-series sampling to understand the dynamics of abundance and distribution of most groups, as well as the lack of experimental manipulations, has made comparisons of patterns of diversity among different habitats (e.g. slope, seamount, canyons, etc).
