On the value of the Immirzi parameter and the horizon entropy
Cássio Pigozzo, Flora S. Bacelar, Saulo Carneiro
In Loop Quantum Gravity (LQG) the quantisation of General Relativity leads to precise predictions for the eigenvalues of geometrical observables like volume and area, up to the val…
Exploring the tug of war between positive and negative interactions among savanna trees: Competition, dispersal, and protection from fire
Flora S. Bacelar, Justin M. Calabrese, Emílio Hernández-García
Savannas are characterized by a discontinuous tree layer superimposed on a continuous layer of grass. Identifying the mechanisms that facilitate this tree-grass coexistence has rem…
Life history and mating systems select for male biased parasitism mediated through natural selection and ecological feedbacks
Flora S. Bacelar, Andrew White, Mike Boots
Males are often the "sicker" sex with male biased parasitism found in a taxonomically diverse range of species. There is considerable interest in the processes that could underlie…
The dynamics of the HIV infection: a time-delay differential equation approach
Flora S. Bacelar, Roberto F. S. Andrade, Rita M. Zorzenon dos Santos
In this work we introduce a differential equation model with time-delay that describes the three-stage dynamics and the two time scales observed in HIV infection. Assuming that the…
Modeling approach to regime shifts of primary production in shallow coastal ecosystems
J. M. Zaldivar, F. S. Bacelar, S. Dueri +4
Pristine coastal shallow systems are usually dominated by extensive meadows of seagrass species, which are assumed to take advantage of nutrient supply from sediment. An increasing…
Joint effects of nutrients and contaminants on the dynamics of a food chain in marine ecosystems
Flora S. Bacelar, Sibylle Dueri, Emilio Hernandez-Garcia +1
We analyze the joint effect of contaminants and nutrient loading on population dynamics of marine food chains by means of bifurcation analysis. Contaminant toxicity is assumed to a…
