Low genetic variation of foliar traits among Prosopis chilensis (Leguminosae) provenances.

Prosopis chilensis (Molina) Stuntz (Leguminosae) is a valuable native species in Argentina that has been proposed to be used in reforestation, afforestation and restoration programmes. Natural provenances show important differentiation in height, shape, spine size, fruits and foliar traits throughout their distribution in the semiarid Monte ecoregion. The goal of this work was to characterize the genetic basis of the leaf variation in P.

Genetic diversity and differentiation among (Leguminosae) populations from dry valleys of Bolivia with different levels of human disturbance and altitude.

The fast expansion of human population around La Paz, Bolivia (3,200-4,100 m.a.s.

Genetic and morphometric variability in Caiman latirostris (broad-snouted caiman), reptilia, Alligatoridae.

Caiman latirostris (broad-snouted caiman) is a crocodilian species from Argentina subject of management plans. The goal of this study was estimating the distribution of genetic variability using RAPD markers and quantitative traits in wild populations of C. latirostris from Santa Fe province, Argentina.

Evolution of small inversions in chloroplast genome: a case study from a recurrent inversion in angiosperms.

Small inversions (SIs) in the chloroplast genome of angiosperms are ubiquitous. These inversions are always flanked by inverted repeats (palindromes or quasipalindromes) between approximately 8 and 50 bp long that form a hairpin structure when the DNA is single-stranded. We evaluated different methodological and empirical issues about SI evolution.

Mating system and population structure of Acacia aroma and A. macracantha (Fabaceae).

Acacia aroma and A. macracantha are closely related species that inhabit northern and central Argentina. The reproductive barriers between them seem to be weak.
