Occurrence of endoparasites in wild Antillean manatees (Trichechus manatus manatus) in Colombia

International Journal for Parasitology: Parasites and Wildlife, 2018
The recognized impact of parasites in wildlife populations demands surveillance of endangered species like the Antillean manatees (Trichechus manatus manatus) in Colombia.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Dynamics of immune response and drug resistance in malaria infection

Malaria Journal, 2006
Background Malaria parasites that concurrently infect a host compete on the basis of their intrinsic growth rates and by stimulating cross-reactive immune responses that inhibit each others' growth.

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

Pest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

Soybean plant architecture influences the capacity of Telenomus podisi to parasitize Euschistus heros eggs: implications for field releases

Pest Management Science, EarlyView.
Increasing soybean plant architectural complexity reduces the ability of Telenomus podisi to parasitize Euschistus heros eggs, highlighting the need to adjust parasitoid release rates in the field according to plant complexity (arrow direction and thickness correspond to the increasing strength of the variable) . Abstract BACKGROUND Plant architectural

Moderna visão da evolução da virulência A modern view of the evolution of virulence

Revista de Saúde Pública, 1995
Atualmente considera-se que parasitas devem evoluir em direção à virulência reduzida, pois patógenos virulentos apresentam maiores probabilidades de levarem seus hospedeiros e eles próprios à extinção.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

Structure of ectoparasite communities of Nyctalus species (Chiroptera: Vespertilionidae) in the Zhiguli State Nature Reserve and Samarskaya Luka National Park (European Russia)

Nature Conservation Research: Заповедная наука
The ectoparasites of the bats (Chiroptera) often act as carriers of infectious agents dangerous to animals and humans. This determines the relevance of studying ectoparasite communities.
