Host defense in Nicrophorus quadripunctatus against brood parasitism by Ptomascopus morio (Coleoptera: Silphidae: Nicrophorinae) [PDF]
, 2006 Few studies have been conducted on the host defenses of insects against brood parasitism. We investigated whether the silphid beetle Ptomascopus morio, a brood parasite of related silphid species Nicrophorus concolor, can also parasitize another silphid ...

Wildlife Letters, EarlyView.Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...

Avian Conservation and Ecology, 2010 In recent decades, many early-succession songbird species have experienced severe and widespread declines, which often are related to habitat destruction. Field borders create additional or enhance existing early-succession habitat on farmland. However,

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

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.

Avian brood parasitism in Italy: another perspective
Avocetta, 2020 We present a quantitative analysis of the data reported in the only published review of parasitism frequency on hosts of Common Cuckoo Cuculus canorus in a Mediterranean area. We first eliminated a bias potentially introduced by the method by which data

The occurrence and consequences of conspecific brood parasitism in the Prothonotary Warbler (Protonotaria citrea) [PDF]
, 2014 Brood parasites avoid costs associated with raising young by adding eggs to another individual’s clutch and providing no parental care. When conspecific brood parasitism occurs in species with high parental investment, we expect hosts to suffer costs for

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Host–parasite interactions shape ecosystems by driving species dynamics, yet their influence is typically considered in terms of host mortality rather than the chemical environments generated during infection and decomposition.

Grazing Impact on Brood Parasitism
, 2014 Anthropogenic land use changes can have tremendous direct and indirect effects on biota. A prevalent land use change in Texas is conversion of land to grazing.

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.
