661por Marra, Daniel Magnabosco, Chambers, Jeffrey Q., Higuchi, Niro, Trumbore, Susan E., Ribeiro, Gabriel H. P. M., dos Santos, Joaquim, Negrón-Juárez, Robinson I., Reu, Björn, Wirth, Christian“…Canopy gaps created by wind-throw events, or blowdowns, create a complex mosaic of forest patches varying in disturbance intensity and recovery in the Central Amazon. Using field and remote sensing data, we investigated the short-term (four-year) effects of large (>2000 m(2)) blowdown gaps created during a single storm event in January 2005 near Manaus, Brazil, to study (i) how forest structure and composition vary with disturbance gradients and (ii) whether tree diversity is promoted by niche differentiation related to wind-throw events at the landscape scale. …”

The first two species exhibited both a 2n = 52 karyotype, but differed in their karyotypic formulae, distribution of constitutive heterochromatin, and chromosomal location of the NOR. …”

669por Guagliardo, Sarah Anne, Morrison, Amy C., Barboza, Jose Luis, Requena, Edwin, Astete, Helvio, Vazquez-Prokopec, Gonzalo, Kitron, Uriel“…CONCLUSIONS: Because larges barges provide suitable mosquito habitats (due to dark, damp cargo storage spaces and ample oviposition sites), we conclude that they likely serve as significant contributors to mosquitoes’ propagule pressure across long distances throughout the Peruvian Amazon. This information can help anticipate vector population mixing and future range expansions of dengue and other viruses transmitted by Ae. aegypti.…”

Longitudinal studies should be performed to determine whether the inhibitory effect of the MOCS on otoacoustic emissions can be an evaluation method and diagnostic tool in populations exposed to mercury.…”
