Fibre optic microarrays for the detection and enumeration of harmful algal bloom species
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: DM Anderson D Kulis D Erdner S Ahn D WaltHarmful algal blooms (HABs) are a serious threat to coastal resources, causing impacts ranging from the contamination of seafood products with potent toxins to mortalities of wild and farmed fish and other marine animals. As the threat from HABs has... -
Phylogeographic structure of the caridean shrimp Palaemon peringueyi in South Africa: further evidence for intraspecific genetic units associated with marine biogeographic provinces
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: PR Teske PW Froneman NP Barker CD McQuaidRecent genetic studies have shown that most widely distributed, passively dispersing invertebrates in southern Africa have regional intraspecific units that are associated with the three main marine biogeographic provinces (cool-temperate, warm-temperate and subtropical). The caridean shrimp Palaemon peringueyi also occurs... -
Genetic characterisation of oyster populations along the north-eastern coast of Tunisia
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: S Dridi MS Romdhane S Heurtebise ElM Cafsi P Boudry S LapègueThe taxonomy of oysters has been traditionally based on characteristics of the shell. More recently, the analysis of protein and DNA polymorphism has provided a means to overcome difficulties in distinguishing the different species of oysters based solely on shell... -
Phylogeography of North African Amietophrynus xeros estimated from mitochondrial DNA sequences
Item type: Journal Article • Journal: African Zoology • Authors: E. Froufe --- CIBIO, Centro de Investigagao em Biodiversidade e Recursos Genéticos, Campus Agrá rio de Vairão, Portugal J. C. Brito --- Departamento de Zoologia e Antropologia, Portugal D. J.

Are melanistic populations of the Karoo girdled lizard, Karusasaurus polyzonus, relics or ecotypes? A molecular investigation
Item type: Journal Article • Journal: African Zoology • Authors: Hanlie M. Engelbrecht --- Department of Botany and Zoology, South Africa P. le Fras N. Mouton --- Department of Botany and Zoology, South Africa Savel R. Daniels --- Department of Botany and Zoology, South AfricaIt has been proposed that melanism in cordylids evolved in response to a single climatic event and that melanistic populations of Karusasaurus polyzonus are relictual. This study investigates the genetic relationships of melanistic and non-melanistic populations of K. polyzonus along... -

A comparison of DNA barcoding markers in West African frogs
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Heidi J. Rockney --- , , USA Caleb Ofori-Boateng --- , Ghana Natsuko Porcino --- , , USA Adam D. Leaché --- , , USADNA barcoding has been proposed as a means of quick species identification using a short standardised segment of DNA. The established barcode gene for animals—the mitochondrial gene cytochrome oxidase one (CO1)—has been plagued by primer failure and low species identification... -
Molecular identification of polydorid polychaetes (Annelida: Spionidae): is there a quick way to identify pest and alien species?
Item type: Journal Article • Journal: African Zoology • Authors: Lee-Gavin Williams --- Department of Botany and Zoology, South Africa Stephen A Karl --- University of Hawai‘i at Mānoa, Hawai‘i Institute of Marine Biology, USA Stanley Rice --- Department of Biology, USA Carol Simon --- Department of Botany and Zoology, South AfricaThe early detection and correct identification of polydorid polychaete species is essential as they are often encountered as invasive alien pests in aquaculture facilities or the intertidal where they may modify the ecosystem. Accurate identification is, however, often hampered by... -
First report of Wolbachia from field populations of Culex mosquitoes in south-western Nigeria
Item type: Journal Article • Journal: African Zoology • Authors: Tosin Segun Ogunbiyi --- Redeemer’s University, Nigeria Philomena Eromon --- Redeemer’s University, Nigeria Paul Oluniyi --- Redeemer’s University, Nigeria Femi Ayoade --- Redeemer’s University, Nigeria Owoicho Oloche --- Redeemer’s University, Nigeria Judith Uche Oguzie --- Redeemer’s University, Nigeria Onikepe Folarin --- Redeemer’s University, Nigeria Christian Happi --- Redeemer’s University, Nigeria Isaac Komolafe --- Redeemer’s University, NigeriaRecent reports on finding Wolbachia-strain infections in field mosquito species in some West African countries and the potential for developing these as disease vector biocontrol tools have prompted a search for Wolbachia in mosquitoes within the study area. Using a... -
Molecular characterization of pests (Chrysomelidae: Bruchinae) of beans (Phaseolus vulgaris) in the Republic of Congo
Item type: Journal Article • Journal: African Zoology • Authors: Valentin Dibangou --- , Republic of Congo Mireille Belle Mbou Okassa --- , Republic of Congo Grace Fidelma Missamou Mazikou --- , Republic of Congo Arsène Lenga --- , Republic of CongoThe bean Phaseolus vulgaris is widely consumed by the Congolese population, because it is rich in protein and has a good nutritional quality. Beetles of the subfamily Bruchinae are pests of bean seeds in the field and storage in the... -
