Annonaceae is a major pantropical family with 113 genera and about 2550 species. Cameroon is one of the most biodiverse countries in Africa but its flora remains incompletely known. In this volume of the Flora of Cameroon, we describe 166 native taxa

Abstract Direct and semidirect estimations of leaf area (LA) and leaf area index (LAI) are scarce in dense tropical forests despite their importance in calibrating remote sensing products, forest dynamics, and biogeochemical models. We destructively

Accurately monitoring tropical forest carbon stocks is a challenge that remains outstanding. Allometric models that consider tree diameter, height and wood density as predictors are currently used in most tropical forest carbon studies. In particular

CDS-Implied Risk of US Delinquency: Implications for the US Debt Ceiling

Autor: John D. Finnerty, Ren-Raw Chen, Bruno G. Kamdem

Publikováno v: The Journal of Fixed Income. 31:6-26

In this article, we use a structural credit risk model developed by Geske (1977) and generalized by Chen et al. (2014) to assess the delinquency risk of US Treasury debt implied by US sovereign CDS spreads. We also use the fitted structural model to

We characterized the flowering patterns of 45 epiphytic orchid species occurring in Cameroonian rainforests to explore the environmental and evolutionary forces driving their phenology. We used a dataset of 3470 flowering events recorded over a perio
