Living on the edge : Roe deer (Capreolus capreolus) density in the margins of Its geographical range [PDF]

open access: yes, 2014
Over the last decades roe deer (Capreolus capreolus) populations have increased in number and distribution throughout Europe. Such increases have profound impacts on ecosystems, both positive and negative.

Density Matrix Methods in Quantum Natural Language Processing [PDF]

open access: yes, 2022
Though vectors are the most commonly used structure to encode the meaning of words computationally, they fail to represent uncertainty about the underlying mean- ing.

Individual differences, density dependence and offspring birth traits in a population of red deer [PDF]

open access: yes, 2008
Variation between individuals is an essential component of natural selection and evolutionary change, but it is only recently that the consequences of persistent differences between individuals on population dynamics have been considered.

Density dependence triggers runaway selection of reduced senescence [PDF]

open access: yes, 2007
In the presence of exogenous mortality risks, future reproduction by an individual is worth less than present reproduction to its fitness. Senescent aging thus results inevitably from transferring net fertility into younger ages.

Experimental evidence for density dependent reproduction in a cooperatively breeding passerine [PDF]

open access: yes, 2009
Temporal variation in survival, fecundity, and dispersal rates is associated with density-dependent and density-independent processes. Stable natural populations are expected to be regulated by density-dependent factors.

Density Measurements for Rectangular Free Jets Using Background Oriented Schlieren [PDF]

open access: yes, 2013
An experimental study incorporating the use of the Background-Oriented Schlieren (BOS) technique was performed to measure the density field of a rectangular supersonic jet.

Population status of Pan troglodytes verus in Lagoas de Cufada Natural Park, Guinea-Bissau [PDF]

open access: yes, 2013
The western chimpanzee, Pan troglodytes verus, has been classified as Endangered on the IUCN Red List since 1988. Intensive agriculture, commercial plantations, logging, and mining have eliminated or degraded the habitats suitable for P. t.

Detection of density-dependent growth and fecundity of helminths in natural infections

open access: yes, 1993
Density-dependent constraints on parasite growth, survival or reproduction are thought to be important in preventing the unchecked increase in parasite numbers within individual hosts or host populations.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
