One of the first reported gall-associated braconids, from 1910, Bracon mendocinus Kieffer & Jörgensen, is removed from the subfamily Braconinae and transferred to the doryctine genus Allorhogas, A. mendocinus (Kieffer & ...

Nectar secretion pattern and effects of nectar removal were comparedin five Argentine species of Lycium (Solanaceae) from several phytogeographical regions with different floral morphologies and floral visitors. The studied ...

With the aim to seek evidences on the possible trade off between hydraulic efficiency and hydraulic safety, from both an evolutionary and an acclimation point of view, we compared root xylem anatomy and derived functional ...

The maintenance of lipid and fatty acids unsaturated composition has been described as one of the mechanisms associated to drought tolerance, but research about the lipid profile in native plants of semiarid environment ...

Mitotic chromosomes numbers and karyotypes of five Argentinean and Chilean taxa were determined in 22 populations. Lycium ciliatum and the varieties of L. chilense analysed had diploid (2n = 24) as well as tetraploid (2n ...

Drought is the main stress that affects growth of native species of Patagonian Monte. Physiological and biochemical traits with functional roles in adaptation to drought are still scarce in native species. The aim of this ...

In semi-arid regions, plants develop various biochemical and physiological strategies to adapt to dry periods. Understanding the resistance mechanisms to dry periods under field conditions is an important topic in ecology. ...

Introduction: Plants have been commonly used in popular medicine of most cultures for the treatment of disease. The in vitro antimicrobial activity of certain Argentine plants used in traditional medicine has been reported. ...
