Reviewing the effects of food provisioning on wildlife immunity [PDF]

, 2018
While urban expansion increasingly encroaches on natural habitats, many wildlife species capitalize on anthropogenic food resources, which have the potential to both positively and negatively influence their responses to infection.

Comparing the egg ultrastructure of three Psorophora ferox (Diptera: Culicidae) populations

Brazilian Journal of Biology, 2017
Characterising the external morphology of mosquito eggs is important, since it facilitates the identification of material from breeding sites and contributes to the understanding of species biology and group systematics.

Exploring protandry and pupal size selection for Aedes albopictus sex separation [PDF]

, 2018
Background: We explored the possibility to improve male/female separation (sexing) in Aedes albopictus by selection of two strains, one toward increasing sex dimorphism and another toward increasing protandry.

Integrative description of two new species of the genus Mesobiotus (Eutardigrada, Macrobiotoidea) from Russia, with an updated phylogeny of the genus

European Journal of Taxonomy
In this study, we describe two new species of Mesobiotus based on morphological data collected through light and scanning electron microscopy. Descriptions include DNA sequences of four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI)

The effects of soils and soil stay on the egg morphology of Neotropical Eulimnadia (Branchiopoda: Limnadiidae)

Journal of Limnology, 2014
Studying the species distribution of Limnadiidae, a family of crustaceans, in environments favourable to their growth and reproduction is made difficult by their extremely short life cycle and the transient existence of adult forms.

Postcopulatory sexual selection [PDF]

, 2002
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to ...

Huffmanela lusitana sp. n. (Nematoda: Trichosomoididae) infecting pouting, Trisopterus luscus (Teleostei: Gadidae) off the Atlantic coast of Portugal

International Journal for Parasitology: Parasites and Wildlife, 2019
Some pouting caught off the Atlantic coast of Portugal are discarded as unmarketable due to a dark discolouration of the skin and muscle. This study investigates the cause of this condition, describes the new parasite species responsible, and highlights ...
