Manaus, Brazil—
Jochen Schöngart darts back and forth along an escarpment just above the Amazon River, a short water taxi ride from downtown Manaus, Brazil. It’s still early this October morning in 2023, but it’s already hot and his face is beaded with sweat. “Look, there’s a piece of ceramic!” he says, nodding to a worn shard lodged between boulders, likely a relic of an earlier civilization. It’s not the only one.

Thermal niches and activity periods in syntopic Phymaturus and Liolaemus lizards from the Andes, Argentina
An Acad Bras Cienc. 2024 Feb 12;96(1):e20191190. doi: 10.1590/0001-3765202320191190. eCollection 2024.ABSTRACTExplanations for differences in thermal biology within and between species of lizards employ concepts of phylogenetic inertia and plasticity. We compared the thermal biology of three liolaemid species in the Andean highlands in Argentina: two allopatric congeners (Phymaturus williamsi and P. aguanegra) each in syntopy with Liolaemus parvus. We predicted intra and inter-generic differences in ecophysiological traits and periods of activity at both sites, ecotypic differences between the (labile) Liolaemus population...

Aedes aegypti oviposition dynamics in towns with low human population density in yungas and dry chaco, Salta, Argentina
Acta Trop. 2024 Feb 13:107150. doi: 10.1016/j.actatropica.2024.107150. Online ahead of print.ABSTRACTWe assessed the presence of Aedes aegypti in five ecorregions of Salta province and compared the oviposition activity of Ae. aegypti using ovitraps in towns of two contrasting ecoregions (yungas and Chaco dry forests) in the province of Salta, Argentina, a major contrast in these ecoregions are rain patterns and altitude. Our aim was to estimate how oviposition activities were associated with the ecoregion and site scale local environmental variables. Mosquito oviposition activity was monitored weekly during the summer usin...
