Article Synopsis
  • The study focuses on the Anolis lizards, particularly the Guadeloupean anole, which exhibits significant color and pattern variation across its twelve subspecies due to environmental factors.
  • Researchers examined five subspecies from two main islands and two offshore islands to explore how geographic isolation and environmental influences affect gene flow and phenotypic diversity.
  • Results indicated that while there is some genetic divergence linked to color differences, significant gene flow persists among the main islands, suggesting that ecological factors and adaptation play critical roles in maintaining this diversity.

The aim of this study was to investigate the hold-by-hold climbing fluency dynamics by using an instrumented holds system that measured the contact time on each hold. Forty-four competitive climbers have been analysed in a regional lead climbing competition during a route composed of 41 instrumented holds on 11 m high artificial climbing wall and with a grade of difficulty 6b on the French scale (IRCRA reported scale: 13). After removing 10 climbers who fell before the top of the route, the 34 remaining climbers who completed the route were clustered according to their total contact time on each hold.

Speed climbing involves an optimization of the velocity of the ascent and the trajectory path during performance. Consequently, any amount of energy spent in the two other directions than vertical, namely the lateral direction and the direction perpendicular to the wall plane, is a potential loss of performance. To assess this principle, we present a study on 3D motion analysis and its 3D visualization for a subject during a speed climbing performance.

Limited data are available on the contribution of wildlife to the spread of antibacterial resistance. We determined the prevalence of resistance to antibiotics in isolates collected from wild animals in 2013 and 2014 and the genetic basis for resistance to third-generation cephalosporin in Guadeloupe. We recovered 52 antibiotic-resistant (AR) strains from 48 of the 884 (5.
