Ejaculate allocation by male sand martins, Riparia riparia [PDF]
, 2001 Males of many species allocate sperm to ejaculates strategically in response to variation in the risk and intensity of sperm competition. The notable exception is passerine birds, in which evidence for strategic allocation is absent.

Journal of Animal Ecology, EarlyView.Partial seasonal migration is rarely considered in a metapopulation context. Here, Haaland et al. use an eco‐evolutionary model revealing how partially migratory metapopulations may arise and be maintained, and how seasonal migrants may cause effects of local extreme climatic events to percolate through metapopulations across diverging temporal and ...

Passerine and Softbill Therapeutics
Veterinary Clinics of North America: Exotic Animal Practice, 2000 Passerines (songbirds) and softbills (toucans and mynahs) are increasingly presented for veterinary care as pet owners and aviculturists recognize that successful medical and surgical treatment can be performed in these often tiny patients. Even with an increasing amount of pharmacokinetic data in birds, the use of extrapolated drug regimens continues ...

Integrative Zoology, EarlyView.Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.
