An ecological field study of the water-rat Nectomys squamipes as a wild reservoir indicator of Schistosoma mansoni transmission in an endemic area

open access: yesMemorias do Instituto Oswaldo Cruz, 2006
Small mammals are found naturally infected by Schistosoma mansoni, becoming a confounding factor for control programs of schistosomiasis in endemic areas. The aims of this study were: to investigate the infection rates by S.

Estimating Wildlife Density as a Function of Environmental Heterogeneity Using Unmarked Data

open access: yesRemote Sensing, 2022
Recent developments to spatial-capture recapture models have allowed their use on species whose members are not uniquely identifiable from photographs by including individual identity as a latent, unobserved variable in the model.

A Multivariate Moran Process with Lotka-Volterra Phenomenology

open access: yes, 2011
For a population with any given number of types, we construct a new multivariate Moran process with frequency-dependent selection and establish, analytically, a correspondence to equilibrium Lotka-Volterra phenomenology.

Population ecology of leafhopper Jacobiasca lybica (Bergevin & Zanon, 1922) (Hemiptera: Cicadellidae) and its control based on degree-days in Moulouya area of Morocco

open access: yesAll Life, 2022
The cotton leafhopper (Jacobiasca lybica) is one of the polyphagous species and its control is mainly based on chemical treatments, however its bio-ecological parameters are still poorly understood especially under Moroccan conditions.

Dynamics of a map with power-law tail [PDF]

open access: yes, 2009
We analyze a one-dimensional piecewise continuous discrete model proposed originally in studies on population ecology. The map is composed of a linear part and a power-law decreasing piece, and has three parameters.

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

open access: yesAdvanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.
