The effect of host density on parasite infection: a power-law model and an experimental test with trematode larvae infecting mussels
Host density is an important factor determining transmission success of parasites in marine ecosystems. Here, we suggest a simple model linking mean...

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...

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,...

Molecular mechanisms of morphine tolerance and dependence; novel insights and future perspectives
Drug addiction is a devastating condition that poses a serious burden on the society. The use of some drugs like morphine for their tremendous...

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...

Plant secondary metabolites and the performance of an exotic, generalist leafroller in California
As an exotic, generalist leafroller the light brown apple moth ( Epiphyas postvittana ) has become established in coastal California where populations...

Effect of Host Plants on the Viability of Black-veined White Aporia crataegi L. at Low Natural Population Density
Abstract—Patterns of interaction of an oligophagous insect, black-veined white Aporia crataegi L., with host plants in years with a low density of...

Integrative developmental ecology: a review of density-dependent effects on life-history traits and host-microbe interactions in non-social holometabolous insects
Population density modulates a wide range of eco-evolutionary processes including inter- and intra-specific competition, fitness and population...

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...

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...

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...

Human dyskerin binds to cytoplasmic H/ACA-box-containing transcripts affecting nuclear hormone receptor dependence
BackgroundDyskerin is a nuclear protein involved in H/ACA box snoRNA-guided uridine modification of RNA. In humans, its defective function is...

SNHG3 could promote prostate cancer progression through reducing methionine dependence of PCa cells
In recent years, morbidity and mortality of prostate cancer (PCa) have increased dramatically, while mechanistic understanding of its onset and...

Insect Mortality Caused by Baculovirus: A Model of Second-Order Phase Transitions
AbstractBaculoviruses, especially prevalent in Lepidoptera, have attracted the most attention as biological insect control agents. Infection with...

The patterns of co-occurrence variation are explained by the low dependence of bark beetles (Coleoptera: Scolytinae and Platypodinae) on hosts along altitude gradients
BackgroundSeparation of biotic and abiotic impacts on species diversity distribution patterns across a significant climatic gradient is a challenge...

The synzootic potential of common epidemics in chamois populations
Southern chamois ( Rupicapra pyrenaica ) is a medium-sized and gregarious mountain ungulate with populations affected by periodic outbreaks of border...

Evidence of a component Allee effect for an invasive pathogen: Hymenoscyphus fraxineus, the ash dieback agent
Invasive pathogens are a major threat to forest health especially in managed forest with a low diversity of tree species. The dieback of Fraxinus spp. ...

Ratio-dependent competitions between a Wolbachia-uninfected bisexual strain and Wolbachia-infected thelytokous strain of the egg parasitoid, Trichogramma dendrolimi Matsumura (Hymenoptera: Trichogrammatidae)
BackgroundWolbachia -infected thelytokous Trichogramma wasps have been considered as potential effective biocontrol agents against lepidopteran pests...

Differential impacts of adult trees on offspring and non-offspring recruits in a subtropical forest
An important mechanism promoting species coexistence is conspecific negative density dependence (CNDD), which inhibits conspecific neighbors by...

Density dependence and the spread of invasive big-headed ants (Pheidole megacephala) in an East African savanna
Supercolonial ants are among the largest cooperative units in nature, attaining extremely high densities. How these densities feed back into their...
