Density dependence and the control of helminth parasites.

open access: yes, 2006
1. The transient dynamics and stability of a population are determined by the interplay between species density, its spatial distribution and the positive and negative density-dependent processes regulating population growth. 2.

Negative density dependence of seed dispersal and seedling recruitment in a Neotropical palm [PDF]

open access: yes, 2014
Negative density dependence (NDD) of recruitment is pervasive in tropical tree species. We tested the hypotheses that seed dispersal is NDD, due to intraspecific competition for dispersers, and that this contributes to NDD of recruitment.

Do natural enemies mediate conspecific negative distance- and density-dependence of trees? A meta-analysis of exclusion experiments

open access: yes, 2022
Conspecific negative distance- and density-dependence is believed to be one of the most important mechanisms controlling forest community assembly and species diversity globally.

An experimental field study of delayed density dependence in natural populations of Aedes albopictus. [PDF]

open access: yesPLoS ONE, 2012
Aedes albopictus, a species known to transmit dengue and chikungunya viruses, is primarily a container-inhabiting mosquito. The potential for pathogen transmission by Ae. albopictus has increased our need to understand its ecology and population dynamics.

Negative density dependence of sympatric Hinge-back Tortoises (Kinixys erosa and K. homeana) in West Africa

open access: yesActa Herpetologica, 2008
A series of 59 transect surveys was conducted in selected wet forest habitats, along the coast of West Africa, to estimate the density distribution of African Hinge-back tortoises (Kinixys homeana and K. erosa).

Non-linear density dependence in time series is not evidence of non-logistic growth

open access: yes, 2008
Time series of population density are often used to seek deviations from logistic regulation by testing for a non-linear decline in per capita growth rate with density.

Data from: High temperature intensifies negative density dependence of fitness in red flour beetles

open access: yes, 2015
Competition for food, space, or other depletable resources has strong impacts on the fitness of organisms and can lead to a pattern known as negative density dependence, where fitness decreases as population density increases.
