Article
Full-text available
African Americans and other ethnic minorities are severely underrepresented in both graduate education and among the professoriate in ecology and evolutionary biology (EEB). In the present research, we take a social psychological approach to studying inclusion by examining interrelationships among challenges to inclusion, the sense of belonging, an...

Full-text available
Recent data from the mitochondrial genome reveal six lineages of Gulf Coast Waterdogs traditionally classified as Necturus beyeri. Here, we use patterns of colour and body size, along with previously published data, to reveal a large, heavily spotted phenotype with an unstriped larva possessing numerous white spots; we re-describe N. beyeri to corr...

Sampling of streams in the middle reaches of the Tana River Basin in Meru National Park, Kenya, from 2010 to 2012 for an NSF-funded International Research Experiences for Students (IRES) project, resulted in the capture of a number of specimens of what were first thought to be Neobola fluviatilis. On closer examination the specimens were determined...
Article
Full-text available
A new species of kitefin shark (Squaliformes; Dalatiidae) is described from the Gulf of Mexico (Western North Atlantic Ocean) based on five diagnostic features not seen on the only other known Mollisquama specimen, the holotype of Mollisquama parini Dolganov which was captured in the Eastern South Pacific Ocean. The new species, Mollisquama mississ...
Article
The Upper Guinean Forests of Guinea, Sierra Leone and Liberia contain high levels of freshwater biodiversity. The Guinean Range and associated Fouta Djallon highlands separate two biogeographical provinces in the region and served as a refugium during past climatic fluctuations. While many species of freshwater fishes are restricted to one biogeogr...

Full-text available
Research on freshwater ecosystems in East Africa is providing a better understanding of the biodiversity in the region. Recent studies of the Kenyan barbs (Cyprininae: Smiliogastrini) revealed diversity within several nominal species from the region. In this study, we examine the molecular and morphological variation in the red-finned barb (Enterom...
Article
Full-text available
Dalatiid sharks are members of a family of predominantly small, midwater meso‐ and bathypelagic chondrichthyans. The family is notable for both its number of monotypic genera and high morphological disparity. Three of the seven dalatiid genera are known only from holotype specimens (Mollisquama parini) or from only a handful of specimens (Euprotomi...
Article
Nest association is a symbiotic reproductive strategy in North American minnows in which a species spawns in the nest substrate of a host species. Host specificity is unknown for the vast majority of nest associates, and presence of a spawning aggregation over a particular nest site has is assumed to be evidence of egg deposition. In this study, we...
Article
Necturus beyeri (Caudata: Proteidae), as conceived by some, contains paedomorphic salamanders distributed from the Ochlockonee drainage of Florida to the Angelina drainage of Texas. Because these salamanders differ in color pattern and karyotype across their geographic range, we performed a phylogeographic analysis that included representatives fro...
Article
Full-text available
In 1932, the Tuckasegee Darter was originally described as Poecilichthys gutselli, from the Tuckasegee River (Little Tennessee River system), North Carolina. In 1968, Miller, citing perceived areas of intergradation, relegated it to a subspecies of Etheostoma blennioides. Recent authors, however, re-elevated E. gutselli to the species level without...
Article
Full-text available
The widespread species, Chiloglanis occidentalis, is recorded in flowing waters from Senegal to Ghana. Recent studies of this species within the Upper Guinean Forests revealed genetic divergence among the populations sampled, suggesting the presence of several unconfirmed candidate species. A detailed study of these populations revealed morphologic...
Article
The phylogenetics and taxonomic status of small African barbs (Cyprininae: Smiliogastrini) remains unresolved despite the recent decision to elevate the genus name Enteromius for the group. The main barrier to understanding the origin of African small barbs and evolutionary relationships within the group is the poor resolution of phylogenies publis...
Article
Full-text available
The majority of the world’s billions of biodiversity specimens are tucked away in museum cabinets with only minimal, if any, digital records of the information they contain. Global efforts to digitize specimens are underway, yet the scale of the task is daunting. Fortunately, many activities associated with digitization do not require extensive tra...
Article
Full-text available
Recent expeditions in Kenya and examination of existing collections confirmed the presence of two undescribed Chiloglanis species and revealed previously unknown diversity within the Athi River system. The two new species are easily distinguished from described congeners in the area by external morphology, allopatric distributions, and genetic mark...
Article
Full-text available
The description of the pocket shark genus Mollisquama (M. parini Dolganov, 1984) is based on a single known specimen collected from the Nazca Ridge of the southeast Pacific Ocean. A second Mollisquama specimen has been captured in the central Gulf of Mexico establishing a considerable range extension and a parturition locality because the specimen...
Article
Full-text available
The diversity and distribution of fish species occurring in the Choctawhatchee River drainage in southeastern Alabama and northcentral Florida were surveyed to obtain historical baseline information. Three hundred seventy-four sites were evaluated for species diversity and distribution in the drainage, including compilation of unpublished records f...
Article
Full-text available
Natural history collections are an irreplaceable and extensive record of life, and form the basis of our understanding of biodiversity on our planet. Broad-scale educational accessibility to these vast specimen collections, specimen images, and their associated data is currently severely hampered. With emerging technologies and massive efforts towa...

Article
African suckermouth catfishes (Mochokidae: Chiloglanis) occur in freshwater throughout tropical Africa. Specimens from all major drainages across Kenya were collected over three field seasons. Here we present a phylogeny inferred from both mitochondrial cytochrome b (cyt b) and introns of the nuclear growth hormone gene (GH). The phylogeny inferred...
Article
This paper presents a new robust EM algorithm for the finite mixture learning procedures. The proposed Spatial-EM algorithm utilizes median-based location and rank-based scatter estimators to replace sample mean and sample covariance matrix in each M step, hence enhancing stability and robustness of the algorithm. It is robust to outliers and initi...
Conference Paper
Full-text available
Building national capacity for research and education in Africa requires coordinated efforts by research and educational institutions. Fish Biodiversity Research and Education in Kenya is an International Research Experience for Students (IRES) funded by the US-NSF. The initiative was started in 2010 and has provided opportunities for undergraduate...

Full-text available
The cyprinid subfamily Oxygastrinae is composed of a diverse group of fishes that has been taxonomically and phyloge- netically problematic. Their great variation in appearance, life histories, and trophic diversity resulted in uncertainty re- garding their relationships, which led to their historical classification across many disparate subfamilie...
