From habitat use to social behavior: natural history of a voiceless poison frog, Dendrobates tinctorius

2019

AbstractDescriptive studies of natural history have always been a source of knowledge on which experimental work and scientific progress rely. Poison frogs are a well-studied group of small Neotropical frogs with diverse parental behaviors, distinct calls, and bright colors that warn predators about their toxicity; and a showcase of advances in fundamental biology through natural history observations. The dyeing poison frog, Dendrobates tinctorius, is emblematic of the Guianas region, widespread in the pet-trade, and increasingly popular in research. This species shows several unusual behaviors, such as the lack of advertisement calls and the aggregation around tree-fall gaps, which remain …

Polypore communities and their substrate characteristics in Atlantic forest fragments in southeast Brazil

2018

Anthropogenic environmental changes have resulted in biodiversity crisis. Although tropical rainforests are one of the global biodiversity hotspots, their biodiversity is still poorly known. Especially fungi are poorly represented in national Red Lists and conservation plans, despite their important role in ecosystem functioning. We studied wood-inhabiting fungi (polypores) in four areas within two Atlantic rainforest fragments in Southeast Brazil. Our aim was to investigate fungal substrate characteristics and community composition. Deadwood amount ranged from 27 to 82 m3/ha among the four study areas and altogether we recorded 53 polypore species. More species were observed in intermediat…

Rivoluzione

2016

L'opera presenta fin dal titolo "Parole in divenire. Un vademecum per l'uomo occidentale" la sua spiccata vocazione multidisciplinare, ricondotta tuttavia in una prospettiva scientificamente omogenea: quella di presentare alcune parole - concetti chiave del sapere filosofico, storico, politico, giuridico, economico nella loro trasformazione semantico-concettuale e la loro incidenza sul presente (e futuro) della cultura 'occidentale', oggi come non mai alla ricerca di una identità rifondativa. "Parole in divenire. Un vademecum per l'uomo occidentale" si rivolge non solo alle diverse componenti del mondo accademico di differenti discipline (docenti e ricercatori desiderosi di confrontarsi con…

Bayesian semiparametric long memory models for discretized event data

2020

We introduce a new class of semiparametric latent variable models for long memory discretized event data. The proposed methodology is motivated by a study of bird vocalizations in the Amazon rain forest; the timings of vocalizations exhibit self-similarity and long range dependence. This rules out Poisson process based models where the rate function itself is not long range dependent. The proposed class of FRActional Probit (FRAP) models is based on thresholding, a latent process. This latent process is modeled by a smooth Gaussian process and a fractional Brownian motion by assuming an additive structure. We develop a Bayesian approach to inference using Markov chain Monte Carlo and show g…

Retour d'expériences sur la concertation vue par les acteurs environnementaux et les élus locaux,

2011

Retrouvez le rapport en ligne, sur le site de l'ADEMEhttp://www.ademe.fr/retour-dexperiences-concertation-vue-acteurs-environnementaux-elus-locaux; Cette étude se penche sur les stratégies des grandes familles d'acteurs de la concertation : les élus locaux, l'Etat et les associations environnementales.L’intérêt pour la participation des citoyens à l’action publique a accompagné la montée en puissancedes préoccupations environnementales à partir des années 1960. Les catastrophes et conflitsenvironnementaux ont joué un grand rôle et favorisé l’entrée en politique de l’environnement. Lesconflits liés à l’environnement ont contribué à faire émerger une participation citoyenne,progressivement in…
