Increasing population density resulting from MWP1a (from 1/655 km2 to 1/71 kmay may be implicated in the development of large and complex societies later in the Holocene.
Changes in locust population density result in a reversible transformation, in a graded manner, between two extreme phenotypic forms, defined as solitary and gregarious phases.
The east coast has fewer, smaller commercial fisheries, but a high coastal population density, resulting in intense exploitation of inshore resources by recreational and subsistence fishers, and this has resulted in the overexploitation of many coastal fish and invertebrate stocks.
While most commercial fisheries are focused on the west and south coasts, the east coast has few and smaller fisheries, but a high coastal population density, resulting in intense exploitation of inshore resources by recreational and subsistence sectors.
Long-term relative competent vector population density resulting from release scenarios that arise from different combinations of release ratio and release duration with male-only (A,D), bi-sex (B,E), and female-only releases (C,F).
We simulated male-only, bi-sex, and female-only releases of each strategy for 100 days (with T s = 50 for combination strategies) at a 1 1 release ratio for populations regulated by different strengths of density dependence by varying the value of β in equation 2. We observed both the long-term (Fig. 3) and minimum relative competent vector population density resulting from each release scenario.
The increase population densities resulted in increased nitrogen (N) levels in the soil.
Invasive plants often establish very high relative population densities, resulting in a near monoculture of conspecific neighbors.
For example, theoretical and empirical work shows that female selectivity generally increases at higher population densities, resulting in stronger sexual selection on males [ 2- 8].
