Disease in Invasive Plant Populations

Annual Review of Phytopathology, 2020
Non-native invasive plants can establish in natural areas, where they can be ecologically damaging and costly to manage. Like cultivated plants, invasive plants can experience a relatively disease-free period upon introduction and accumulate pathogens over time.

Plant–pollinator population dynamics

Theoretical Population Biology, 2010
We formulate and analyze a multi-generation population dynamics model for pollinators' mutualism with plants. The centerpiece of our model is an analytical expression for population-level plant-pollinator interactions extrapolated from a model of individual-level flowers and bees interactions.

Plant growth and population dynamics.

2006
The main purpose of quantitative nematological research is to achieve an optimal economical protection of crops against plant-parasitic nematodes. To accomplish this, the costs of control measures must be adjusted to the costs of the expected yield reduction compared to the yield in a situation without the need for control.

PLANT POPULATION BIOLOGY AT THE CROSSROADS

Evolution, 1978
from 1968 to 1972, this volume is a goldmine of information concerning the biological interactions of acridid grasshoppers, especially those of economic importance. If Uvarov had lived longer, I suspect that a third volume would have been necessary, since the present one at 613 pages is 200 longer than the first volume (still in print), which includes ...

Coadaptation in Plant Populations

1977
One of the most important questions of plant breeding is whether alleles at different loci act independently or whether the population genotype is structured so that favored combinations of alleles occur more frequently than expected under randomness. Studies employing allozyme loci as markers have demonstrated that the distribution of alleles in both ...

Palaeoecology and plant population dynamics

Trends in Ecology & Evolution, 1988
The pollen record of the past 10-20 thousand years is a source of data both on long-term climatic change and on the dynamics of plant populations in response to climatic change. Time sequences of pollen accumulation rates record invasions of tree taxa over 10(1)-10(3) years.

History of Plant Population Genetics

Annual Review of Genetics, 1999
▪ Abstract  This review of plant population genetics focuses on the genetic foundations of the processes that have led to documentable improvements in cultivated plants since the earliest domestications took place perhaps 13,000 years ago. Nearly all human civilizations have depended heavily on inbreeding plants (particularly wheat, barley, soybeans ...

Group selection in plant populations

Theoretical and Applied Genetics, 1987
Several mechanisms have been proposed for group selection, to account for the evolution of altruistic traits. One type, Neighbourhood models, suggests that individuals react with those immediately around them, but with no recognition mechanism. The organization of plant populations seems especially favorable for this type of selection.

Asymmetric competition in plant populations

Trends in Ecology & Evolution, 1990
Recently there has been much interest in the hypothesis that competition between individual plants is asymmetric or onesided: larger individuals obtain a disproportionate share of the resources (for their relative size) and suppress the growth of smaller individuals.

Pachyderms, primates, plants and population

Reproduction, Fertility and Development, 2002
In the past, growth in human population has often been associated with species loss. Current rates of population growth, both globally (1 million more births than deaths every 103 hours) and regionally, pose a threat of additional ecological damage.
