Avian Brood Parasitism: Variation in Host Repsonse
, 2016 Obligate brood parasites forego the cost of parental care by laying their eggs in the nest of other species, often to the detriment of that species. About 1% of all bird species are obligate brood parasites, but the most well-known and commonly studied ...

Ibis, EarlyView.Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

Brood Parasitism and the Evolution of Cooperative Breeding in Birds
Science, 2013 Power in Numbers Avian brood parasites target particular bird species to raise their offspring, sometimes at great cost to the foster family. Feeney et al. (p. 1506 ; see the Perspective by Spottiswoode

Dataset from Host density predicts the probability of parasitism by avian brood parasites
, 2018 The spatial distribution of hosts can be a determining factor in the reproductive success of parasites. Highly aggregated hosts may offer more opportunities for reproduction but can have better defences than isolated hosts.

Insect Conservation and Diversity, EarlyView.Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

The impact of learning foster species' song on the evolution of specialist avian brood parasitism
Obligate interspecific avian brood parasites do not build nests of their own but lay their eggs in the nests of other species. It has been proposed that a flexible song learning mechanism (copying the heterospecific songs of the foster species ...

Insect Conservation and Diversity, EarlyView.Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.

On the origin of brood parasitism in altricial birds
The probability that obligate interspecific brood parasitism (OP), among altricial birds evolved directly from the normal breeding (no parasitism, NP) mode or indirectly through intraspecific nest parasitism (INP) was examined by using maximum-likelihood

Insect Molecular Biology, EarlyView.Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.
