    The molecular systematics of Ulva Linnaeus and Enteromorpha Link (Ulvales, Chlorophyta) from the South Western Cape, South Africa
    (2002) Kandjengo, Lineekela; Bolton, John J; Hedderson, Terry A
    Both Ulva and Enteromorpha are very common, ubiquitous, and environmentally important genera of green seaweeds. The evolutionary history of Ulva species is poorly understood, stemming from a lack of diagnostic, non-molecular systematic characters. This study addresses the following questions: i) Do the two genera represent distinct entitiesj ii) What are the relationships among local putative species; iii) Do the recognized species represent monophyletic lineages; iv) How closely are local species related to those from elsewhere? These questions are addressed using nuclear ribosomal DNA ITS sequences from 48 local samples plus data on 16 samples from GenBank.

    The seaweed flora of the Palm Beach area, KwaZulu Natal, South Africa and its biogeographical affinities
    (2000) Kandjengo, Lineekela; De Clerck, Olivier; Bolton, John J
    The aim of this investigation is to study the seaweed flora of Palm Beach, Kwazulu-Natal, South Africa, and to determine its biogeographical affinities. A collection from the Palm Beach area produced a list of 130 taxa, comprising 13 Chlorophyta and 15 Phaeophyta 102 Rhodophyta. Included in this list are 56 species from neighbouring sites, Trafalgar and Port Edward. Data from existing databases were used to compare the seaweed flora of the Palm Beach area with that of other sites along the South African coastline. A PCA analysis was used to interpret the data and the Palm Beach area aligned with the south coast sites. The Palm Beach flora is primarily confined to the warmer South coast. The flora composition of the area is distinct from that of a typical transitional region. It is concluded that the biogeog raphical affinity of the macroalgal flora of the Palm Beach area is warm temperate.
