Due to their complexity, coral reefs are difficult to study especially when considering the role that the interplay between the terrestrial and marine environments has in shaping distribution of marine, terrestrial, and amphibious species. Many organisms live in remote areas of the ocean and inhabit both terrestrial and marine environments. Such am...
Article
The multifaceted ability to produce, transmit, receive, and respond to acoustic signals is widespread in animals and forms the basis of the interdisciplinary science of bioacoustics. Bioacoustics research methods, including sound recording and playback experiments, are applicable in cognitive research that centers around the processing of informati...
Article
Madagascar is known as a biodiversity hotspot, providing an ideal natural laboratory for investigating the processes of avian diversification. Yet, the phylogeography of Madagascar's avifauna is still largely unexamined. In this study, we evaluated phylogeographic patterns and species limits within the Rufous Vanga, Schetba rufa, a monotypic genus...
Article
The honeyeaters are the most species-rich clade of birds east of Wallace's Line. They occupy a wide range of habitats, from desert to rainforest, and occur throughout Australia, New Guinea, and oceanic islands across Wallacea and the Pacific. Honeyeater natural history is well charac-terised, but comparative studies of this group are hampered by th...

The House Crow (Corvus splendens) is a useful study system for investigating the genetic basis of adaptations underpinning successful range expansion. The species originates from the Indian subcontinent, but has successfully spread through a variety of thermal environments across Asia, Africa and Europe. Here, population mitogenomics was used to in...
Article
The Streak-breasted Scimitar Babblers of the Pomatorhinus ruficollis species complex are found in most of the forested habitats across southern and eastern Asia. The diversification history of this group is obscured by high plumage variation across populations and conflicting genetic signal across loci. We combined genetic and geographic data from...

The Golden Whistler (Aves: Passeriformes: Pachycephalidae) Pachycephala pectoralis sensu lato has long played a key role in the development of the theory of allopatric speciation (Mayr 1932a, b; Mayr 1942; Galbraith 1956). The P. pectoralis species complex formerly comprised 60–70 nominal subspecies and so had a distribution spanning the Indo-Pacif...
Article
We examined the phylogeography of the Western Hemispheric Sedge Wren (Cistothorus platensis) which occurs in grasslands from Canada to Tierra del Fuego. Genetic data indicate that Sedge Wren is paraphyletic with Mérida (Cistothorus meridae) and Apolinar's (Cistothorus apolinari) wrens and the currently recognized Sedge Wren is composed of a minimum...
Article
The passerine family Meliphagidae (the honeyeaters) comprises 175–180 species in 40–50 genera. It is an iconic element of the Australo-Papuan avifauna and also occurs in Indonesia and on remote Pacific Ocean islands. Building on previous molecular studies that have pioneered a renewed understanding of the family's circumscription and systematics, w...
Article
With more than 70 described subspecies distributed from Java to Fiji, the Golden Whistler species complex (Aves: Pachycephala pectoralis/melanura) is the world's most geographically variable bird species. We sequenced ten genes totalling 5743 bp from 202 individuals and 32 nominal subspecies, mostly from the Australasian and Polynesian lineages. We...
Article
The world's richest mangrove‐restricted avifauna is in Australia and New Guinea. The history of differentiation of the species involved and their patterns of intraspecific genetic variation remain poorly known. Here, we use sequence data derived from two mitochondrial protein‐coding genes to study the evolutionary history of eight co‐distributed ma...
Article
Colonization and subsequent isolation across deep-water barriers is thought to be the primary driver of diversification in insular birds. Shallow-water barriers and intra-island isolation are less well-documented drivers of avian diversification. We examined the relative roles of different geographical barriers in the diversification of Aethopyga s...

Given the short home range of sand flies, combining remote sensing and collection point data give a powerful insight into th...
Article
Full-text available
The mangrove forests of Australasia have many endemic bird species but their evolution and radiation in those habitats has been little studied. One genus with several mangrove specialist species is Gerygone (Passeriformes: Acanthizidae). The phylogeny of the Acanthizidae is reasonably well understood but limited taxon sampling for Gerygone has cons...

Evaluations of relationships among honeyeaters (Passeriformes : Meliphagidae) have used dense taxon and nucleotide sampling. Here we focus on the systematically contentious meliphagid genus Lichenostomus. We use data from two molecular markers that were common to two major recent studies, the mitochondrial protein-coding gene ND2 and the nuclear in...
Article
The Sahara Desert was recently proposed as the agent of vicariant speciation in the North African elephant-shrew (order Macroscelidea, Elephantulus rozeti). Based on evidence from molecular dating, however, this speciation event was estimated as having occurred in the Miocene, an early date of origin for an extant species, predating the dramatic cl...
Article
We sequenced 1869 bp of mtDNA (cyt b and ND2) from 80 specimens of Lepidocolaptes affinis, a montane bird species of Mesoamerica, sampled at 34 localities from Mexico to Costa Rica. The species showed moderate genetic diversity (π=0.0045) and phylogeographic structure (Φ(ST)=0.12-0.95). The phylogeographic pattern indicated the Nicaragua Depression...

Understanding the relationships and evolution of flowerpeckers has been challenging, particularly as no phylogenetic study has as yet assessed the group. Here, we present a first such analysis of this clade based on sequences of two mitochondrial genes and one nuclear intron. Our analyses offer strong support for monophyly of the Dicaeidae. Within...
Article
Full-text available
The past two decades have seen major outbreaks of influenza viruses and flaviviruses that are spread at least in part by migratory birds. Although much new information has accumulated on the natural history of the viruses, and on the geography of migration by individual bird species, no synthesis has been achieved regarding likely patterns of sprea...
Article
We explore the phylogenetic relationships of fantails (Aves: Rhipiduridae) using molecular characters derived from two nuclear introns and two mitochondrial genes. Our results indicate that Rhipidura hypoxantha is not a true fantail, but rather a member of the Stenostiridae clade that is morphologically and behaviourally convergent with fantails. W...
Article
Full-text available
We assessed song rates among male Cerulean Warblers (Dendroica cerulea) in Ozark riparian forest in southeastern Missouri to characterize song rate variation and estimate how many males may be missed during censuses. Average (± SD) songs per 5-min intervals for continuous 4-hr observation periods varied from 3.1 ± 4.8 (mated males) to 36.0 ± 18.7 (...
Article
The Buarremon brush-finches represent a complex suite of populations distributed in the montane New World Tropics from Mexico south to South America. Traditional taxonomic arrangements have separated populations of this genus into three species, based on plumage variation, although plumage patterns are well known to exhibit homoplasy. We present a...
Article
Full-text available
Recent studies have increasingly implicated deep (pre-Pleistocene) events as key in the vertebrate speciation, downplaying the importance of more recent (Pleistocene) climatic shifts. This work, however, has been based almost exclusively on evidence from molecular clock inferences of splitting dates. We present an independent perspective on this qu...
Article
Establishing species limits can be challenging for organisms in which few variable morphological characters are available, such as Schiffornis turdina, a Neotropical suboscine bird of long-debated taxonomic affinities. Apart from its dull plumage and secretive behavior, this taxon is well-known for its subtle but discrete within-species geographic...
