Cross-sectional study of the burden of vector-borne and soil-transmitted polyparasitism in rural communities of Coast Province, Kenya. [PDF]

open access: yes, 2014
BACKGROUND: In coastal Kenya, infection of human populations by a variety of parasites often results in co-infection or poly-parasitism. These parasitic infections, separately and in conjunction, are a major cause of chronic clinical and sub-clinical ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Evolution of Parasitoidism in Hymenoptera

open access: yesTurkish Journal of Agriculture: Food Science and Technology
Insects, the most diverse group of animals, are known to benefit society for a sustainable future. By focusing on the use of natural enemies of pests, including parasitoids and predators, the need for biological pest control for the conservation of ...

Buchanan and the Social Contract: Coordination Failures and the Atrophy of Property Rights

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT James Buchanan advocated that societies should be based on a social contract. He rejected anarchy, seeing it as a “Hobbesian jungle” that calls for government intervention to maintain social order. He also opposed theories of spontaneous order. These views led to debates about the compatibility of Buchanan's works with classical liberalism and

Reactive oxygen species-dependent Toll/NF-κB activation in the Drosophila hematopoietic niche confers resistance to wasp parasitism

open access: yeseLife, 2017
Hematopoietic stem/progenitor cells in the adult mammalian bone marrow ensure blood cell renewal. Their cellular microenvironment, called ‘niche’, regulates hematopoiesis both under homeostatic and immune stress conditions.

Intrinsic competition and its effects on the survival and development of three species of endoparasitoid wasps [PDF]

open access: yes, 2009
In natural systems, pre-adult stages of some insect herbivores are known to be attacked by several species of parasitoids. Under certain conditions, hosts may be simultaneously parasitized by more than one parasitoid species (= multiparasitism), even ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

A Holistic Approach to Parasitoid–Host Interaction Along an Elevational Gradient Revealed Coevolution Driven by Host Foraging Strategy

open access: yesEcology and Evolution
The evolutionary processes that shape host‐parasitoid coexistence in a changing environment are poorly understood. We examined the large‐scale distribution of highly specialised polysphinctine Darwin wasps associated with spiders along an elevational ...
