Abstract Applications of DNA barcoding include identifying species, inferring ecological and evolutionary relationships between species, and DNA metabarcoding. These applications require reference libraries that are not yet available for many taxa and geographic regions. We collected, identified, and vouchered plant specimens from Mpala Research Center in Laikipia, Kenya, to develop an extensive DNA‐barcode library for a savanna ecosystem in equatorial East Africa. We amassed up to five DNA barcode ...

Use of bio-indicators in monitoring environmental quality in the West African sub-region is limited. In a study to evaluate the occurrence and distribution of bryophytes and lichens in relation to air pollution in Nigeria, three species each of bryophytes (Calymperes palisotii, Erpodium coronatum, B. leptophyllum) and lichens (Parmelia tinctorum, Physcia sp. and Trentifolia sp.) were encountered. For categories of plants, the number of species (diversity) and frequency of occurrence increased as one ...

Abstract Whether wild herbivores confer biotic resistance to invasion by exotic plants remains a key question in ecology. There is evidence that wild herbivores can impede invasion by exotic plants, but it is unclear whether and how this generalises across ecosystems with varying wild herbivore diversity and functional groups of plants, particularly over long‐term (decadal) time frames. Using data from three long‐term (13‐ to 26‐year) exclosure experiments in central Kenya, we tested the effects of ...

Parameters influencing gum yield such as tapping techniques and soil mineral elements had earlierbeen investigated while there is dearth of information on effect of morphological characteristics on gumyield. This study investigated effects of height and girth on yield of Acacia senegal L. in the naturalforests. Three heights and girth classes were purposely selected. Trees which heights and girth fell withinthose classes were selected randomly and tapped at constant height classes with varying girth ...

This study attempted to assess the soil suitability in the derived savanna zone of Edo State, Nigeria for the cultivation of some tree crops. The research specifically aimed to evaluate soil suitability for cashew and rubber supported by suitability maps for both crops. In terms of land suitability evaluation, mapping units 1 and 2, with an area coverage of 27.4 ha of the entire research area (100 ha) were found to be marginally suitable (S3) for rubber cultivation but moderately suitable (S2) for ...
