Simple remedy for pitfalls in detecting negative density dependence
Conspecific negative density dependence (CNDD) is one of the processes that can maintain high species diversity by decreasing population growth rates...
-
Nutrients strengthen density dependence of per-capita growth and mortality rates in the soil bacterial community
Density dependence in an ecological community has been observed in many macro-organismal ecosystems and is hypothesized to maintain biodiversity but...

Negative density-dependence buffers against mismatch-induced population decline in the Sinai baton blue butterfly
Phenological mismatches caused by climate change pose a major threat to global biodiversity, yet relatively few studies have reported population...

Tree mycorrhizal type mediates conspecific negative density dependence effects on seedling herbivory, growth, and survival
Tree mycorrhizal type plays an important role in promoting plant species diversity and coexistence, via its mediating role in conspecific negative...

On a population model with density dependence and Allee effect
We study the dynamics of a discrete model with two different stages of the population, the pre-adult stage governed by a Beverton–Holt-type map and...

Density-Dependent Growth in Salmonids: A Meta-analysis
The Salmonidae comprise a large group of ecologically and economically valuable species. We surveyed the published literature relating growth to...

Quantifying the nature and strength of intraspecific density dependence in Arctic mosquitoes
Processes that change with density are inherent in all populations, yet quantifying density dependence with empirical data remains a challenge. This...

The Ghost of Density-Dependence: Environmental (Hydrological) Factors Drive the Numerical Changes of Young Migratory Trout Salmo trutta in a Lake District Stream (UK), 1966–1996
Finding empirical support for the “paradigm of density-dependence” has been a major focus of ecological and fishery research. Quantifying...

Life-history traits and density dependence in metapopulations of a tropical moss: a monoicous species that is almost dioicous
Life-history traits, such as reproductive allocation, sexual expression, sex ratio, and reproductive success, are central aspects of a species’...
-
Study methodology impacts density-dependent dispersal observations: a systematic review
The relationship between animal dispersal and conspecific density has been explored in various study systems but results in terms of both the...

Demographic signals of population decline and time to extinction in a seasonal, density-dependent model
Nearly all wild populations live in seasonal environments in which they experience regular fluctuations in environmental conditions that drive...

Components of Brown Trout Age-Class Density Dynamics
Brown trout population dynamics are driven by endogenous and exogenous factors acting together or interacting. Endogenous mechanisms include...

Large-scale genotypic identification reveals density-dependent natal dispersal patterns in an elusive bird of prey
BackgroundNatal dispersal, the distance between site of birth and site of first breeding, has a fundamental role in population dynamics and species’...

Population Density of Resident and Nonresident Small Forest Mammals
AbstractWhen assessing the abundance of small mammals using traditional methods, an abundance index that is the number of individuals per unit of...

The interplay between scale, pollination niche and floral attractiveness on density-dependent plant–pollinator interactions
Pollinators mediate interspecific and intraspecific plant–plant indirect interactions (competition vs. facilitation) via density-dependent processes,...

Role of BDNF in Neuroplasticity Associated with Alcohol Dependence
AbstractChronic alcohol consumption is characterized by disturbances of neuroplasticity. Brain-derived neurotrophic factor (BDNF) is believed to be...

Phenology, parasitism and density dependence of Psyllaephagus bliteus on Eucalyptus camaldulensis
Glycaspis brimblecombei is an invasive insect species that specifically feeds on Eucalyptus leaves. Native from Australia, this species has spread to...

Drug dependence in cancer is exploitable by optimally constructed treatment holidays
Cancers with acquired resistance to targeted therapy can become simultaneously dependent on the presence of the targeted therapy drug for survival,...
-
Model-based entropy estimation for data with covariates and dependence structures
Entropy is widely used in ecological and environmental studies, where data often present complex interactions. Difficulties arise in linking entropy...

Density-dependence and environmental variability have stage-specific influences on European grayling growth
Fish somatic growth is indeterminate and can be influenced by a range of abiotic and biotic variables. With climate change forecast to increase the...
