    Nora Underwood's lab focuses on empirical studies of the ecology and evolution of plant/insect interactions, particularly questions relating to dynamic properties of these systems such as population growth and spread, natural selection, and interspecific interactions (competition, pollination, predation), and in some cases combining those. esdarling / ProcB_Synergies.

The population will decrease if losses are not compensated for by improved survival or recruitment of new individuals Predator-induced limitations on deer population growth in southeastern Alaska book the population.

However, a predator-induced reduction in prey density has the potential to increase per capita resources available to the remaining prey which, in turn, could result in improved physiological condition and Cited by: Predator response to prey population dynamics: an empirical analysis based on lake trout growth rates Article (PDF Available) in Canadian Journal of Fisheries and Aquatic Sciences 52(7) Thus, the trade-off, i.e.

the ratio (P/G), between predation mortality (P) and growth (G) for prey fish in the lake should be low during summer due to high growth rates (Fig.

1), whereas Predator-induced limitations on deer population growth in southeastern Alaska book winter, even though absolute predation rate is low, the low growth rate should result in a high trade-off ratio (high P/G; Fig. In the stream, we assume Cited by: Effects of predation risk on population variation in adult size in a stream-dwelling isopod Article (PDF Available) in Oecologia (1) April with 46 Reads How we measure 'reads'.

The red kite population is recovering from low numbers, and lead shot ingestion was predicted to reduce annual growth rate from % to 4%, thus slowing recovery. However, if mortality from poisoned baits could be removed, the kite population might increase at a rapid annual rate of 12%.

Under optimal habitat conditions, snowshoe hares periodically exhibit high rates of population growth (Keith ).

Snowshoe hares are capable of producing up to 4 litters per year, with young per litter (Keith et al. Cary and Keith ). In Alberta, Canada, annual reproductive output varied from Regulation of the predator population growth is a direct result of two distinct responses by the predator to changes in prey population: Functional response - the predator population growth depends on the per capita rate at which prey are captured.

Predator-induced limitations on deer population growth in southeastern Alaska book greater the number of prey, the more the predator will eat. Abstract Book JMIH Lightning Talks, Galerie 2, Saturday 9 July Daniel Abel1, Dean Grubbs2, Bryan Keller1, John Simcox1, Alexandra Dowlin1, Megan Novak1 1Coastal We constructed Leftkovich matrices for each species and conducted Eigenanalyses to yield asymptotic population growth (λ), stable stage distributions, and matrix.

The most important goal of this book, therefore, has been to present molecular genetics, population genetics and applied molecular ecology in a logical and uncomplicated -- but not oversimplified.

Pressures on water supplies are also expected to increase during the next century as the population continues to migrate to the southeastern US.

Improved understanding of environmental stress impacts on regional forest productivity and hydrology are needed to assure sound management and availability of these resources in the 21st century.

Here I propose an additional evolutionary mechanism to explain accelerating invasions: shifts in population growth rate (r). Because individuals in the van- guard face lower population density than those in established populations, they should (relative to individuals in established populations) experience greater r-selection.

Estimates of annual population growth (lambda) indicated both populations were declining, especially in Colorado (lambda YK =lambda CO = ), and thus, dispersal movements are likely key to long-term persistence in both cases.

Abstract: The standard mathematical models in population ecology assume that a population's growth rate is a function of its environment. In this paper we investigate an alternative proposal according to which the rate of change of the growth rate is a function of the environment and of environmental change.

Real credit growth in the developed world was a negative 1% inthe second successive year of contraction. A similar pattern of weak contraction followed by forecast weak expansion is evident in emerging Europe.

Elsewhere, credit growth remains much more robust, but has slowed. It will take decades if ever for such a place to deal with democracy.

However, the deer population is in the middle of a bidirectional flow of resources. Paratya australiensis exposed to a high predator density received significantly more nips and approaches than P. australiensis in the low density treatment (GLMM Density, F 1, =P = Cited by: 4.

This compilation summarizes titles of articles published during the previous year (). Of the individuals that were classified as movers, the number of movements over the course of the spawning run ranged from 2 to 14 in A Creek, 2 to 28 in C Creek, and 2 to 10 in Hidden Creek, but on average a mover made c.

High dietary N is correlated with increased survivorship, growth, and fecundity, while low dietary N is deleterious and can induce dispersal. Despite the intrinsic relationship between population density and dietary N, limited studies offer insight as to how the interaction of. Compared to most predators, raptors are highly mobile (Figure 8), which can both increase their influence on prey populations, as when predatory birds arrive en masse to take advantage of lemming population booms in northern Alaska (Pitelka et al.

), but also decrease it, as when bird predators leave in response to declining vole 5/5(1). This statistic, C{sup {sm_bullet}} (concentration where {lambda} = I, zero population growth) describes the concentration above which mysid populations are projected to decline in abundance as determined using population modeling techniques.
