Autor: Mathew Herrnegger, Pierre Kray, Gabriel Stecher, Nelly Cherono Kiplangat, Dennis Otieno, Luke Olang, Sharon E. Nicholson

Publikováno v: Journal of Hydrology: Regional Studies, Vol 55, Iss , Pp 101951- (2024)

Study region: Lake Bogoria and Lake Baringo, Rift Valley, Kenya Study focus: Starting around 2010, several of Kenya’s Rift Valley lakes experienced significant rises in water levels. There is presently fear of an ecological catastrophe should the w

Responses of Sap Flux Densities of Different Plant Functional Types to Environmental Variables Are Similar in Both Dry and Wet Seasons in a Subtropical Mixed Forest

Autor: Kechao Huang, Quan Wang, Dennis Otieno

Publikováno v: Forests, Vol 12, Iss 8, p 1007 (2021)

Subtropical mixed forest ecosystems are experiencing dramatic changes in precipitation and different plant functional types growing here are expected to respond differently. This study aims to unravel the water use patterns of different plant functio

Canopy Transpiration and Stomatal Responses to Prolonged Drought by a Dominant Desert Species in Central Asia

Autor: Daxing Gu, Quan Wang, Dennis Otieno

Publikováno v: Water, Vol 9, Iss 6, p 404 (2017)

In arid and semiarid lands, canopy transpiration and its dynamics depend largely on stomatal sensitivity to drought. In this study, the sap flow of a dominant species, Haloxylon ammodendron growing in Central Asian deserts, was monitored using Granie

Publikováno v: PLoS ONE, Vol 8, Iss 11, p e81359 (2013)

BACKGROUND: Natural forest succession often affects soil physical and chemical properties. Selected physical and chemical soil properties were studied in an old-growth forest across a forest successional series in Dinghushan Nature Reserve, Southern
