Are Large Herbivores Vectors of Terrestrial Subsidies for Riverine Food Webs?
Masese, Frank O.; Ka´tya, Abrantes G; Gettel, Gretchen M.; et.., al. (Springer Science+Business Media New York, 2015-03-17)The tropical savannas of Africa have witnessed a dramatic reduction in native large mammalian herbivore populations. The consequences of these changes for terrestrial-aquatic food-web linkages are poorly documented. ... -
Influence of catchment land use and seasonality on dissolved organic matter composition and ecosystem metabolism in headwater streams of a Kenyan river
Masese, Frank O.; SalcedoBorda, Jessica S.; Gettel, Gretchen M.; et.., al. (Biogeochemistry An International Journal, 2017-01)Headwater streams influence the biogeochemical characteristics of large rivers and play important roles in regional and global carbon budgets. The combined effects of seasonality and land use change on the biogeochemistry ... -
Trophic structure of an African savanna river and organic matter inputs by large terrestrial herbivores: A stable isotope approach
Masese, Frank O.; Ka'tya, Abrantes G.; Gettel, Gretchen M.; et.., al. (John Wiley & Sons Ltd ; Freshwater Biology., 2018-06). Knowledge of trophic structure is important to understand sources and pathways of energy resources in community ecology and to identify determinants of ecosystem changes. Yet, little is known from rivers of African ...
