Rapid sexing of selected Galliformes by polymerase chain reaction

Czech Journal of Animal Science, 2012
Vent sexing of one-day-old chicks in commercial hatcheries has long been common practice and can be highly accurate. However, there are circumstances when this technique is not applicable such as smaller breeds, non-domestic birds, or where is the ...

Temporal Niche Partitioning as a Coexistence Mechanism Between China’s Endemic Elliot’s Pheasant (Syrmaticus ellioti) and Its Predator, the Leopard Cat (Prionailurus bengalensis)

Diversity
Understanding predator-prey coexistence mechanisms is essential for conserving endemic species in montane ecosystems. Galliformes serve as critical ecological indicator species, yet their populations are declining globally due to habitat fragmentation ...

Intensive trapping of blood-fed Anopheles darlingi in Amazonian Peru reveals unexpectedly high proportions of avian blood-meals.

PLoS Neglected Tropical Diseases, 2017
Anopheles darlingi, the main malaria vector in the Neotropics, has been considered to be highly anthropophilic. However, many behavioral aspects of this species remain unknown, such as the range of blood-meal sources. Barrier screens were used to collect

Uncertainty in identifying local extinctions: the distribution of missing data and its effects on biodiversity measures [PDF]

, 2016
Identifying local extinctions is integral to estimating species richness and geographic range changes and informing extinction risk assessments. However, the species occurrence records underpinning these estimates are frequently compromised by a lack of ...

Linkage mapping reveals sex-dimorphic map distances in a passerine bird [PDF]

, 2005
Linkage maps are lacking for many highly influential model organisms in evolutionary research, including all passerine birds. Consequently, their full potential as research models is severely hampered.
