PLoS ONE, 2014 Studying the larval dispersal of bottom-dwelling species is necessary to understand their population dynamics and optimize their management. The black-lip pearl oyster (Pinctada margaritifera) is cultured extensively to produce black pearls, especially ...

Global Ecology and ConservationThe 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

Dispersal and Repulsion of Entomopathogenic Nematodes to Prenol
Biology, 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.

FIELD EXPERIMENTS WITH DISPERSED OIL AND A DISPERSANT IN AN INTERTIDAL ECOSYSTEM: FATE AND BIOLOGICAL EFFECTS [PDF]
International Oil Spill Conference Proceedings, 1985 ABSTRACT Experiments with chemically and ultrasonically dispersed Arabian light crude oil and a dispersant (Finasol OSR 5) were carried out on an intertidal sand flat in the Wadden Sea (German Bight). “Bremerhaven Caissons,” flow through mesocosms for intertidal field experiments, allowed pollutant addition to the enclosed water during ...

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

Liposomes of phosphatidylcholine: a biological natural surfactant as a dispersing agent
Coloration Technology, 2007 Disperse dyes are very hydrophobic molecules that in their commercial form are usually milled in the presence of large amounts of dispersing agents (synthetic surfactants). Other dispersing agents are added as auxiliaries during the dyeing process. These synthetic surfactants were substituted for liposomes prepared with phosphatidylcholine, a well ...

Ki-67 acts as a biological surfactant to disperse mitotic chromosomes [PDF]
Nature, 2016 Eukaryotic genomes are partitioned into chromosomes that form compact and spatially well-separated mechanical bodies during mitosis. This enables chromosomes to move independently of each other for segregation of precisely one copy of the genome to each of the nascent daughter cells. Despite insights into the spatial organization of mitotic chromosomes

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
