Genetic Patterns Suggest Exponential Population Growth in a Declining Species
Recent theoretical studies have suggested that patterns of sequence divergence and relationships among alleles sampled from Populations are affected by population size and rates of growth. However, the degree of concordance between changes-to Populations and to the patterns of allelic relationships withinpopulations is not well understooL Threshold effects, time lags, or the effects of earlier ...
متن کاملPopulation genetic correlates of declining transmission in a human pathogen
Pathogen control programs provide a valuable, but rarely exploited, opportunity to directly examine the relationship between population decline and population genetics. We investigated the impact of an ~12-fold decline in transmission on the population genetics of Plasmodium falciparum infections (n = 1731) sampled from four clinics on the Thai-Burma border over 10 years and genotyped using 96 ...
متن کاملPopulation growth patterns of four species of aphelenchoides on fungi.
Qualitative and quantitative differences in population growth patterns of Aphelenchoides rutgersi from Florida, A. sacchari from Jamaica, A. dactylocercus from Great Britain, and A. cibolensis from New Mexico were assessed on 28 species of fungi. The patterns of population growth of A. rutgersi and A. sacchari were statistically similar although not identical, and they differed considerably fro...
متن کاملRegional patterns of declining butternut (Juglans cinerea L.) suggest site characteristics for restoration
Butternut trees dying from a canker disease were first reported in southwestern Wisconsin in 1967. Since then, the disease has caused extensive mortality of butternut throughout its North American range. The objectives of this study were to quantify changes in butternut populations and density across its range and identify habitat characteristics of sites where butternut is surviving in order t...
متن کاملDeclining Orangutan Encounter Rates from Wallace to the Present Suggest the Species Was Once More Abundant
BACKGROUND Bornean orangutans (Pongo pygmaeus) currently occur at low densities and seeing a wild one is a rare event. Compared to present low encounter rates of orangutans, it is striking how many orangutan each day historic collectors like Alfred Russel Wallace were able to shoot continuously over weeks or even months. Does that indicate that some 150 years ago encounter rates with orangutans...
