Molecular Genetic Perspectives on Avian Brood Parasitism [PDF]

Integrative and Comparative Biology, 2002
Advances in molecular genetic techniques have provided new approaches for addressing evolutionary questions about brood parasitic birds. We review recent studies that apply genetic data to the systematics, population biology, and social systems of avian brood parasites and suggest directions for future research.

Significant resource niche overlap between competing parasitoids does not prevent their successful co‐existence

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Different species that exploit the same resources can sometimes co‐exist in the same habitat through resource sharing. For example, if resources are superabundant, then they can be easily partitioned interspecifically among different individuals. However, when resources

Plant secretions prevent wasp parasitism in nests of wool-carder bees, with implications for the diversification of nesting materials in Megachilidae

Frontiers in Ecology and Evolution, 2015
Bees make use of plant substrates in more ways than any other group of insects, which is probably linked to their diversification and ecological success.

Coevolution in action: disruptive selection on egg colour in an avian brood parasite and its host. [PDF]

PLoS ONE, 2010
Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection.Here,

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Lack of effect of microhabitat charaacteristics on nest predation and brood parasitims in creamy-bellied thruss (Turdus Amaurochalinus) [PDF]

, 2013
Nest predation and brood parasitism are key factors affecting nest survival in passerine birds. As a result, birds may select nest sites that minimize the probability of nests being found by predators or by brood parasites. Nevertheless, evidence remains

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‐

Variation in plasma oxidative status and testosterone level in relation to egg-eviction effort and age of brood-parasitic common cuckoo nestlings [PDF]

, 2012
To avoid competition for parental care, brood-parasitic Common Cuckoo (Cuculus canorus) nestlings evict all of the host's eggs and nestlings within a few days after hatching.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Bird Interspecific Brood Parasitism Record in the Third Century

Birds
The phenomenon of interspecies brood parasitism, characterized by parasitic birds depositing their eggs within the nests of unrelated host species for subsequent hatching and rearing, represents a pivotal aspect of ornithological research, owing to its ...
