TLDR
This work aimed to determine whether American Prosopis sections arose in North or South America, and to explain the current distribution of their species on the basis of their genetic relationships.Abstract:
Aim The genus Prosopis includes 44 species and has a pseudoamphitropical, disjunct distribution. We aimed to determine whether American Prosopis sections arose in North or South America, and to explain the current distribution of their species on the basis of their genetic relationships.
Location South-western USA, Mexico, Caribbean Antilles, Peru–Ecuador, central and northern Argentina, south-western Argentina (Patagonia) and Cuyo, south-western Asia and northern Africa.
Methods Internal transcribed spacer fragments from 21 species of Prosopis were sequenced and the data were used to analyse the phylogenetic relationships using Microlobius and Mimosa as outgroups. Genetic distances were calculated to estimate the degree of divergence. Dispersal–vicariance (DIVA) analysis was conducted to help understand the biogeographical history of the genus.
Main conclusions The sections Strombocarpa and Algarobia are not monophyletic. Prosopis argentina (section Monilicarpa) and the species of Algarobia are included in single clade. The phylogeny, DIVA analysis, and the pattern of genetic distances indicate that the ancestral area for the American species was wide, from south-western USA to Central and northern Argentina. Successive vicariance events split this area, and long-distance dispersal episodes (perhaps mediated by birds) led to recolonizations from North to South America, and vice versa.read more

Air Layering and Tiny-Air Layering Techniques for Mesquite [Prosopis laevigata (H. B. ex Willd.) Johnst. M. C.] Tree Propagation
Rafael Ramírez-Malagón,Erika Delgado-Bernal,Anatoly Borodanenko,Luis Pérez-Moreno,José Luis Barrera-Guerra,Héctor G. Núñez-Palenius,Neftalí Ochoa-Alejo +6 more
TL;DR: Investigation of asexual mesquite propagation methods in Mexico found the highest response (90%) of air layerings was obtained with 500 mg l−1 IBA, having an average number of 1,785 roots per layering, while for the tiny-air layering method, the best treatment was 3.0 mg l + Chrysal, which induced 90% of rooting.

TL;DR: The studied community presents intermediate values that are considered as common in comparison to other arid and semi-arid vegetation associations of Northeastern Mexico and the abundance curve of the species was well adjusted to the geometric model, and the distribution is associated with adverse environments such as semi- arid.

Genomic and biotechnological interventions in Prosopis cineraria: current status, challenges and opportunities
TL;DR: Little progress has been made for this tree species in the area of population genetics, genomic and genetic resources development in the form of transcriptome sequencing, generation of ESTs against the heat and drought stresses, and identification of genomic SSRs, and the feasibility of micropropagation as a non-GM biotechnology has been demonstrated.
biogeography - a critique
TL;DR: It is argued that diva is not ideally suited to distinguishing between dispersal and vicariance because it cannot a priori take into account the age of divergences relative to the timing of barrier formation, and suggested that model-based approaches are promising.

Confidence limits on phylogenies: an approach using the bootstrap.
TL;DR: The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.
