Living at the edge : increasing stress for plants 2-13 years after the retreat of a tropical glacier
Rapid warming is a major threat for the alpine biodiversity but, at the same time, accelerated glacial retreat constitutes an opportunity for taxa and communities to escape range contraction or extinction. We explored the first steps of plant primary succession after accelerated glacial retreat under the assumption that the first few years are crit...
Automatic detection of optical signatures within and around Floating Tonga-Fiji pumice rafts using MODIS, VIIRS, and OLC...
An underwater volcanic eruption off the Vava'u island group in Tonga on 7 August 2019 resulted in the creation of floating pumice on the ocean's surface extending over an area of 150 km2. The pumice's far-reaching effects from its origin in the Tonga region to Fiji and the methods of automatic detection using satellite imagery are described, making...
Triatomine feeding profiles and Trypanosoma cruzi infection, implications in domestic and sylvatic transmission cycles i...
Understanding the blood meal patterns of insects that are vectors of diseases is fundamental in unveiling transmission dynamics and developing strategies to impede or decrease human-vector contact. Chagas disease has a complex transmission cycle that implies interactions between vectors, parasites and vertebrate hosts. In Ecuador, limited data on h...
Improved genetic map identified major QTLs for drought tolerance- and iron deficiency tolerance-related traits in ground...
...
A deep understanding of the genetic control of drought tolerance and iron deficiency tolerance is essential to hasten the process of developing improved varieties with higher tolerance through genomics-assisted breeding. In this context, an improved genetic map with 1205 loci was developed spanning 2598.3 cM with an average 2.2 cM distance between ...
Quantifying the shelter capacity of coral reefs using photogrammetric 3D modeling : from colonies to reefscapes
...
Structural complexity plays a key role in the functioning of coral reef ecosystems. Reef-building corals are major contributors to this complexity, providing shelter and food for numerous invertebrates and fish species. Both structural complexity and shelter capacity of reefscapes are determined by several components such as spurs and grooves, slop...
Rhizobia use a pathogenic-like effector to hijack leguminous nodulation signalling
...
Legume plants form a root-nodule symbiosis with rhizobia. This symbiosis establishment generally relies on rhizobium-produced Nod factors (NFs) and their perception by leguminous receptors (NFRs) that trigger nodulation. However, certain rhizobia hijack leguminous nodulation signalling via their type III secretion system, which functions in pathoge...
Social structure, habitat use and injuries of Indo-Pacific bottlenose dolphins (Tursiops aduncus) reveal isolated, coast...
Understanding population structure and habitat use of poorly known cetacean species is a first step toward scientifically informed management decisions. In the southern range of New Caledonia (South Pacific), a long-term dataset of Indo-Pacific bottlenose dolphins (Tursiops aduncus) encounters primarily during winter seasons 1997 to 2019 (473 group...
Closing the diversity and inclusion gaps in francophone public health : a wake-up call [editorial]
L&8217;épidémie de choléra en Haïti : histoire d'un fiasco des Nations Unies et de la persévérance d&8217;un (collectif)...
Alors que la pandémie de Covid-19 fait des ravages dans le monde, il est certainement utile de prendre un peu de recul épidémiologique. La lecture de l'ouvrage de Renaud Piarroux concernant son expérience de lutte contre l’épidémie de choléra en Haïti entre 2010 et 2018 est riche d’enseignements. Il montre le fiasco et les errances du système des N...
