Leech Parasitism of the Gulf Coast Box Turtle, Terrapene carolina major (Testudines:Emydidae) in Mississippi, USA [PDF]

open access: yes, 2017
Ten leeches were collected from a Gulf Coast box turtle, Terrapene carolina major, found crossing a road in Gulfport, Harrison County, Mississippi, USA. Eight of the leeches were identified as Placobdella multilineata and 2 were identified as Helobdella

Mycorrhizal identity of neighbouring trees shapes seedling survival and plant–soil feedbacks through trait and light interactions

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–soil feedbacks (PSF) play a central role in determining forest community dynamics, with trees associated with arbuscular mycorrhizal fungi (AMF) often experiencing negative PSFs, while those associated with ectomycorrhizal fungi (EMF) experience positive PSFs ...

Effect of Spodoptera litura Eggs on Parasitism in Telenomus remus Under Different Refrigerated Conditions

open access: yesGuangdong nongye kexue
【Objective】Telenomus remus is the dominant egg parasitoid of Spodoptera frugiperda, and Spodoptera litura is an excellent host for the reproduction of T. remus. The study was conducted to clarify the effects of refrigeration temperature and duration of S.

Effects of Banana Plantation Pesticides on the Immune Response of Lepidopteran Larvae and Their Parasitoid Natural Enemies

open access: yesInsects, 2012
Basic research on the insect immune response has progressed dramatically within the last two decades, showing that immunity is one of the most effective defenses against foreign invaders.

Trematode infection buffers heat stress in blue mussels Mytilus edulis: The role of heat shock proteins

open access: yesJournal of Animal Ecology, EarlyView.
The study shows that parasite infection changes heat shock protein expression and can increase heat tolerance in blue mussels. By separating parasite and temperature effects, the results suggest that infection may improve survival during heat stress, highlighting important parasite–host interactions for climate change resilience. Abstract The influence

Generation cycles in experimental populations of a multivoltine insect

open access: yesJournal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Parasitic Infections

open access: yesClinics in Colon and Rectal Surgery, 2019
AbstractParasitic infections of the gastrointestinal tract are a cause of morbidity to millions of individuals worldwide. These parasites are endemic in underdeveloped countries with poor sanitation allowing for spread through contaminated water supplies.

The Savage Worlds of Henry Drummond (1851–1897): Science, Racism and Religion in the Work of a Popular Evolutionist

open access: yesJournal of Religious History, EarlyView.
Abstract The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

To improve ecological understanding, collect infection data

open access: yesEcosphere, 2019
Ecologists seek to understand and predict how organisms respond to multiple interacting biotic and abiotic influences, an increasingly difficult task under anthropogenic change.

A tale of three kingdoms: Members of the Phylum Nematoda independently acquired the detoxifying enzyme cyanase through horizontal gene transfer from plants and bacteria [PDF]

open access: yes, 2018
Horizontal gene transfer (HGT) has played an important role in the evolution of nematodes. Among candidate genes, cyanase, which is typically found only in plants, bacteria and fungi, is present in more than 35 members of the Phylum Nematoda, but absent ...
