Species Composition and Spatial Ecology of Amazonian Understory Mixed-Species Flocks in a Fragmented Landscape
… and roads. Conservation, however must take species interactions into consideration as they play a pivotal part the maintenance of several biological processes in the tropics. One of the most conspicuous interspecific interactions are seen in mixed-species flocks of birds, which in the …

Phylogenomics and Geometric Morphometrics Define Species Flocks of Snowtrout (Teleostei: Schizothorax) in the Central Himalayas
… lakes in the Himalayas. There are more than 30 species of Schizothorax across the region. The speciation and diversity of the Snowtrout in the vast hinterlands of the Himalayan Region has not been fully explored. Three species in Lake Rara, Western Nepal are considered a species flock, …

Winter habitat use by Blackburnian Warblers (Dendroica fusca) in Los Amarillos, Colombia
… were found. Size and composition of the mixed-species flocks joined by Blackburnian Warblers were also compared to habitat features. Habitat variables were measured in circular plots centered where a Blackburnian Warbler was first seen. The same set of variables was measured in randomly located …

EVOLUTION OF FRESHWATER CRABS IN LAKE MALAWI AND THE LAKE MALAWI BASIN IN THE EAST AFRICAN RIFT VALLEY
… East African Rift Valley and is home to a single species of freshwater crab, the Malawi Blue Crab. Little is known about species diversity and the phylogenetic relationships of the freshwater crabs of Lake Malawi, in contrast to the lake’s highly-diverse cichlid fish species flocks. The Malawi …

Survey of Nasal Mites (Acari: Rhinonyssidae, Ereynetidae, Turbinoptidae) in Birds from Three States in the United States
… nasal mites is the Rhinonyssidae, in which mite species may have different levels of host specificity from host orders to families or even species level. Nasal mites in North America have been surveyed in different locations, such as studies ranging from the Gulf Coast of the US to Canada. From …

Unlikely Friendships - An Exploratory Review into the Defining Criteria of Associative Behaviour between Vertebrate Species
… on associations between individuals of different species has been conducted worldwide on a plethora of taxa and documented under multiple terminologies. This paper reviews the breadth of this complex social behaviour by collating relevant association papers across all vertebrates that use one or …

Predators vs. Prey: The information ecology of warning signals
… prey, how information use varies across predator species, and whether this can operate in a predator community in the wild. First, I investigated if previous experience with toxins increases great tits’ reliance on social information about novel aposematic prey, but found that toxin load had no …

Multidimensional Approach to Comparative Avian Visual Systems
… world have been limited to a small number of species and tended to focus on a single visual trait. This approach has constrained our ability to understand the diversity and evolution of the avian visual system. The goal of this dissertation was to characterize multiple visual dimensions on …

Reproductive Isolation and Genetic Divergence in a Young "Species Flock" of Pupfishes (Cyprinodon sp.) from San Salvador Island, Bahamas
… speciation is instrumental to understanding the species diversity observed today. Diverging populations are intriguing, because speciation has not reached an endpoint, yet the process that may eventually lead to distinct species can be studied. Systems that contain many putative species and/or …
