RICHNESS, GEOGRAPHIC DISTRIBUTION AND ECOLOGICAL ASPECTS OF THE FERN COMMUNITY WITHIN THE MURICI ECOLOGICAL STATION IN THE STATE OF ALAGOAS, BRAZIL

Richness, geographic distribution and ecological aspects of the fern community within the Murici Ecological Station in the state of Alagoas, Brazil

We conducted a floristic survey of ferns within the Murici Ecological Station (remnant of the northeastern Atlantic Forest), located near the municipalities of Messias and Murici, in the state of Alagoas, Brazil.To increase knowledge of the ferns of Alagoas, we evaluated the species occurring in the study area in terms of richness, composition, geo

Low temperature quantum bounds on simple models

In the past few years, there has been considerable activity around a set of quantum bounds on transport coefficients (viscosity) and chaos (Lyapunov exponent), relevant at low temperatures.The interest comes from the fact that Black-Hole models seem to saturate all of them.The goal of this work is to gain physical intuition about the quantum mechan
