Phylogeography of Darlingtonea Kentuckensis and Molecular Systematics of Kentucky Cave Trechines
… is widely distributed along the eastern band of the Mississippian/Pennyroyal plateau in Kentucky and northern Tennessee. DNA sequence data from the mitochondrial gene cytochrome oxidase subunit I (COI) was collected from one to four individuals from 27 populations, and patterns of …

An alternative hypothesis for explaining anomalies in the fine scale distribution patterns of Colophospermum mopane : Are shrub and tree forms genetically distinct ?
… explain the fine scale distribution patterns of shrub and tree Colophospermum mopane (Caesalpinioideae). Genetic distinctiveness between growth forms is investigated as an alternative hypothesis. Tree and shrub C. mopane from the riparian and inland savanna zones were sampled at four sites in …

Genetic characterization of Theobroma cacao L Nicaraguan
Genetic composition of Theobroma cacao L., including 60 Nicaraguan farmers accessions, was investigated using nine microsatellite (SSR) markers. Fourteen breeders accessions from Experimental Center “El Recreo”, INTA, Nicaragua, two Criollos accession from CATIE, Costa Rica, and two accessions from …

Phylogeographic structure in the CFR genus Pauridia revealed by inter-simple sequence repeat amplification
… Floristic Region, South Africa, has high numbers of rare and endemic plants. Many, including Pauridia Harv., are geophytes in the Hypoxidaceae. The two species of Pauridia differ in morphology and range, with P. minuta occupying a wide range across lowland CFR and P. longituba being restricted to …

Characterization of the intraspecific variation within the nickel (Ni) hyperaccumulator species Senecio coronatus (Asteraceae): a preliminary analysis of genetic population structure and shoot proteome expression
… and detoxify exceptionally high concentrations of metals in their aboveground tissues, without exhibiting any apparent signs of toxicity. Despite nickel (Ni) hyperaccumulator plants representing the largest percentage of known metal accumulator taxa (over 75%), the underlying genetic and …

Population Fragmentation and Genetic Diversity of Chrosomus sp. cf. saylori (Clinch Dace)
… sp. cf. saylori) is a newly recognized species of minnow with a restricted distribution in southwestern Virginia. Field sampling and genetic analysis support the hypothesis that Clinch Dace populations are small and fragmented. Analysis of neutral genetic markers shows that most Clinch Dace …

Genetic diversity and relationships among Nguni cattle populations in three Southern African countries
… are adapted to the different ecological zones of Southern Africa. Previous work on characterising the Nguni has been limited to within-country studies. Thus, the aim of the current study was to genetically characterise South African (SA) Nguni, Mozambican Nguni (Landim) and Swazi Nguni …

Effects of iso-alpha-acids on rumen fermentation and comparison of microbial populations between rumens and continuous culture fermenters
… vitro. The first experiment examined the effects of iso-alpha-acids from Humulus lupulus (Hops) extract on rumen fermentation. Iso-alpha-acid extract (IE) was provided to continuous culture fermenters to supply 0 (CON), 600 (LOW), 1200 (MED) or 1800 mg of IE/kg of diet DM/day. There was no effect …

Variation in growth, nutrition and phytochemicals of sequentially harvested shoots and fruits, and genetic studies of Lagenaria siceraria landraces in South Africa
Lagenaria siceraria (Molina) Standley, a member of the Cucurbitaceae family, is valued for its many uses, serving as a crucial food source with edible plant parts such as leaves, shoots, fruit pulp, and seeds. However, studies on L. siceraria regarding the relationship between shoot, peduncle and …

Olive leaf spot: epidemiology and control
The overall goal of this research was to improve the understanding of the environmental factors affecting development of olive leaf spot (OLS) in New Zealand olive groves and to develop strategies for the disease management. The effects of temperature, relative humidity (RR), leaf wetness and leaf …
