A multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level.
The phylogeny of the tribe Aquilini (eagles with fully feathered tarsi) was investigated using 4.2 kb of DNA sequence of one mitochondrial (cyt b) and three nuclear loci (RAG-1 coding region, LDH intron 3, and adenylate-kinase intron 5). Phylogenetic signal was highly congruent and complementary between mtDNA and nuclear genes. In addition to single-nucleotide variation, shared deletions in nuc...
متن کاملRanging behaviour and habitat preferences of the Martial Eagle: Implications for the conservation of a declining apex predator
Understanding the ranging behaviours of species can be helpful in effective conservation planning. However, for many species that are rare, occur at low densities, or occupy challenging environments, this information is often lacking. The Martial Eagle (Polemaetus bellicosus) is a low density apex predator declining in both non-protected and protected areas in southern Africa, and little is kno...
متن کاملThe collection and database of Birds of Angola hosted at IICT (Instituto de Investigação Científica Tropical), Lisboa, Portugal
The bird collection of the Instituto de Investigação Cientítica Tropical (Lisbon, Portugal) holds 5598 preserved specimens (skins), mainly from Angola, Mozambique, Guinea-Bissau, São Tomé and Principe, and Cape Verde. The subset collection from Angola includes 1560 specimens, which were taxonomically revised and georeferenced for the publication of this data paper. The collection contains a tot...
متن کاملUsing areas of known occupancy to identify sources of variation in detection probability of raptors: taking time lowers replication effort for surveys
Species occurring at low density can be difficult to detect and if not properly accounted for, imperfect detection will lead to inaccurate estimates of occupancy. Understanding sources of variation in detection probability and how they can be managed is a key part of monitoring. We used sightings data of a low-density and elusive raptor (white-headed vulture Trigonoceps occipitalis) in areas of...
متن کاملInterspecific Allozyme Differentiation among North Atlantic White-headed Larid Gulls
ABSTR•CT.--I assessed patterns of allozymic variation in Larus argentatus (Herring Gulls), L. cachinnans (Yellow-legged Herring Gulls), L. fuscus (Lesser Black-backed Gulls), L. glaucoides (Iceland Gull), L. hyperboreus (Glaucous Gulls), and L. marinus (Greater Black-backed Gull). I surveyed 34 presumed structural gene loci over 479 individuals. All birds were monomorphic and fixed for the same...
