Parasitism

, 2012
Parasitism is defined in different ways by different authors, usually reflecting their research interest and bias. Parasitism, as used here, is defined as a close association between two organisms in which one, the parasite, depends on the other, the ...

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Ultrasmall epibiont Nanosynbacter lyticus strain TM7x and host bacteria transcriptional activity after initial host parasitism

Journal of Oral Microbiology
Background Oral Saccharibacteria Nanosynbacter lyticus strain TM7× lives as an ultrasmall epibiont on the surface of its host, Schaalia odontolytica strain XH001. Establishing this interaction is a poorly understood multi-step process. The recovery phase

Data from: Host nest site choice depends on risk of cuckoo parasitism in magpie hosts

, 2017
Avian brood parasites impose large fitness costs on their hosts and, thus, brood parasitism has selected for an array of host defensive mechanisms to avoid them.

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

Insect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Efecto del parasitismo del isópodo bopírido Ionella agassizi (Isopoda: Epicaridea) (Bornnier, 1900) sobre la fisiología nutricional del nape Neotrypaea uncinata (M. Edwards, 1837) (Decapoda: Thalassinidea) Effects of parasitism in nutritional physiology of the ghost shrimp Neotrypaea uncinata parasitized by the isopod Ionella agassizi

Revista Chilena de Historia Natural, 2000
El nape Neotrypaea uncinata se encuentra parasitado en sus branquias por el isópodo Ionella agassizi. Trabajos anteriores han señalado que I. agassizi provoca un efecto negativo en la biología reproductiva del nape, afectando significativamente tanto el ...

Diversity, distribution and parasitism rates of fleas (Insecta: Siphonaptera) on sigmodontine rodents (Cricetidae) from Argentinian Patagonia

, 2018
Fleas have great medical relevance as vectors of the causative agents of several diseases in animals and humans and rodents are the principal reservoirs for these pathogens. Argentinian Patagonia has the highest diversity of rodent fleas in South America.
