Introduced parasites threaten native host species that lack effective defenses. Such parasites increase the risk of extinction, particularly in small host populations like those on islands. If some host species are tolerant to introduced parasites, this could amplify the risk of the parasite to vulnerable host species. Recently, the introduced parasitic nest fly Philornis downsi has been implicated in the decline of Darwin's finch populations in the Galápagos Islands. In some years, 100% of… Expand
Invasive Parasites and the Fate of Darwin's Finches in the Galapagos Islands: The Case of the Vegetarian Finch (Platyspiza crassirostris)
ABSTRACT The Vegetarian Finch, Platyspiza crassirostris, is a relatively unstudied Darwin's finch that appears to be in decline in the Galapagos Islands. We monitored 11 nests of Vegetarian FinchesExpand
Alien Invasion: Biology of Philornis Flies Highlighting Philornis downsi, an Introduced Parasite of Galápagos Birds.
TLDR
Studies of native and introduced Philornis are reviewed in an attempt to identify factors that may influence virulence and consider implications for the conservation of hosts in the Galápagos. Expand
Intensity-dependent energetic costs in a reciprocal parasitic relationship
TLDR
The results suggest that tolerance is the prevailing coping mechanism for both fish and mussels when infected, while resistance mechanisms appear to be confined to the behavioural level. Expand
Host resistance and tolerance of parasitic gut worms depend on resource availability
TLDR
This study evaluated how low and high resource diets affect Cuban tree frog resistance and tolerance of a skin-penetrating, gut nematode Aplectana sp. Expand
Can hosts tolerate avian brood parasites? An appraisal of mechanisms
TLDR
It is concluded that evidence for true tolerance is inconclusive and scarce, and that experimental studies controlling for possible confounding variables are clearly needed to critically demonstrate tolerance defence in hosts. Expand
Anti-parasite behaviour of birds

  • 2018
TLDR
A brief review of anti-parasite behaviours in birds, divided into five major categories: body maintenance, nest maintenance, avoidance of parasitized prey, migration, migration and tolerance, and briefly considers the interaction of different behaviours, such as sunning and preening. Expand
Exploring the immune response, tolerance and resistance in proliferative kidney disease of salmonids
ABSTRACT Proliferative kidney disease (PKD) of salmonids is a disease of economic and environmental concern caused by the myxozoan parasite Tetracapsuloides bryosalmonae. Finer details of the immuneExpand
Contrasting consequences of different defence strategies in a natural multihost-parasite system.
TLDR
It is found that main and alternative hosts have contrasting defence strategies, which gave rise in turn to contrasting virulence and parasite success, and hint that defence efficiency is a crucial intervening element in these processes. Expand
Early-Life Diet Affects Host Microbiota and Later-Life Defenses Against Parasites in Frogs.
TLDR
The study demonstrates that the diet of Cuban tree frog tadpoles affects the gut microbiota and defenses against parasitic gut worms of frogs, but these effects depend on the stage of the host and infection, respectively. Expand
The effect of Philornis downsi in the reproductive success of the Little Vermilion Flycatcher on the Isabela Island – Galápagos
TLDR
Die Bestande vieler endemischer Vogelarten der Galapagos Inseln sind in den letzten Jahren drastisch zuruckgegangen, unter ihnen die Rubintyrannen, seine erste Brutphase vor dem Beginn der Regenzeit hat. Expand
