Dispersal and Repulsion of Entomopathogenic Nematodes to Prenol

open access: yesBiology, 2019
Chemosensory cues are crucial for entomopathogenic nematodes (EPNs)—a guild of insect-killing parasitic nematodes that are used as biological control agents against a variety of agricultural pests.

Mother knows best: dominant females determine offspring dispersal in red foxes (Vulpes vulpes). [PDF]

open access: yesPLoS ONE, 2011
Relatedness between group members is central to understanding the causes of animal dispersal. In many group-living mammals this can be complicated as extra-pair copulations result in offspring having varying levels of relatedness to the dominant animals,

Optimal Control for a Dispersing Biological Agent

open access: yesJournal of Agricultural and Resource Economics, 2014
A bioeconomic model is developed to analyze the optimal control management strategies for an introduced herbivore in a two-compartment ecosystem. This paper analyzes cost-effective control strategies that decrease the spillover effects of the herbivore on endangered plant species, thereby reducing extinction pressure and increasing benefits.

Continuum of global to local dispersal frameworks highlights the increasing threat of pine wilt disease in China

open access: yesGlobal Ecology and Conservation
The global introduction of human-mediated trade and local dispersal through transport or natural pathways are major processes and contributors to biological invasion. To effectively prevent and manage biological invasion, global introduction pathways and

Environmental heterogeneity blurs the signature of dispersal syndromes on spatial patterns of woody species in a moist tropical forest.

open access: yesPLoS ONE, 2018
We assessed the relative importance of dispersal limitation, environmental heterogeneity and their joint effects as determinants of the spatial patterns of 229 species in the moist tropical forest of Barro Colorado Island (Panama). We differentiated five

Dispersal of pristine graphene for biological studies

open access: yesRSC Advances, 2016
Herein, we address the conflicting behaviour of different pristine graphene dispersions through their careful preparation and characterization in aqueous media.

High Emigration Propensity and Low Mortality on Transfer Drives Female-Biased Dispersal of Pyriglena leucoptera in Fragmented Landscapes.

open access: yesPLoS ONE, 2017
Dispersal is a biological process performed in three stages: emigration, transfer and immigration. Intra-specific variation on dispersal behavior, such as sex-bias, is very common in nature, particularly in birds and mammals.

Solid Dispersions of Biologically Active Substances

open access: yes, 2020
Due to the rapid development of nanotechnologies, materials, in particular , solid dispersions (SDs), which are actively introduced into the life of modern man, have been obtained. Special progress in this area is observed in industry and medicine. The use of SDs in agriculture is lagging far behind, despite the growing number of scientific papers on ...

Controlled radical polymerization in dispersed systems for biological applications [PDF]

open access: yesProgress in Polymer Science, 2020
Polymeric nanoparticles show great promise in a range of biomedical applications, improving pharmacokinetic properties, dose requirements and immune response in drug delivery and bioimaging. Common synthesis techniques such as self-assembly, while prevalent, are unscalable and require the use of organic solvents, or extensive purification. In contrast,
