How has competition for resources historically affected human population growth?

Density-dependent factors are environmental variables that influence population growth in relation to the population density. These factors typically become ... Oct 27, 2013 ... Besides temperature, we found that rainfall was a further important factor only in the warmer area (Trento province). Abundant rainfall during ... ... density dependent with density independent effects on vital rates and population trajectories. Our data and model do not support the hypothesized recent ... May 1, 2024 ... Density dependent limiting factors are associated with organisms or biotic factors that impact population size. May 17, 2017 ... ... density interacting with environmental factors (i.e. refugia, competition and predation). 2.3. Experiment 1: density-dependent larval survival. Although the dispersal of animals is influenced by a variety of factors, few studies have used a condition-dependent approach to assess it. This study investigated the underlying mechanisms of spatio-temporal dynamics of Atlantic cod (Gadus morhua) in the Gulf of Maine (GoM). Summary. 1. There has been increasing recognition that catastrophes are an important factor in modelling threatened populations. However, density dependence ... Nov 22, 2024 ... Most density-dependent factors, which are biological in nature (biotic), include predation, inter- and intraspecific competition, accumulation ... Apr 6, 2016 ... In real-life situations, population regulation is very complicated and density-dependent and independent factors can interact. A dense ...
