Bio-ecological, phytosociological and conservation aspects of relictual and disjointed populations of Simethis mattiazzi (Vandelli) Sacc. (Xanthorrho…

2012

Two populations of Simethis mattiazzi (Xanthorrhoeaceae) were recently discovered in the Channel of Sicily – (1) Punta Bassana (Marettimo Island) and (2) Mount S. Giuliano (western Sicily) – at a considerable distance from the nearest stations hitherto known, located in southern Sardinia, the Pontine Islands Archipelago and Tunisia. The taxonomical and distributive aspects of this species are analysed to highlight the relictual and biogeographical significance of the disjointed and fragmentary nuclei distributed in several small islands of the Channel of Sicily, the Italian Peninsula and North Africa. Some morphological, biological, ecological and phytosociological aspects of the two new po…

Semantic Wiki for the Protection, Emergency Management and Knowledge of Cultural Heritage

2012

Nowadays, the trend for cultural heritage data management is the generation of numerical corpus that can be viewed and distributed online. To make information available on the web and to provide easy access a web platform application is needed it will be important to make use of a web platform that allows easy creation and editing of web pages as well as a management of their links. Wiki semantico per la tutela, la conoscenza e la gestione dell’emergenza Fornire un accesso alle informazioni relative al patrimonio culturale al di là del supporto che possono fornite i testi, è importante. Per far fronte a specifi che esigenze è richiesto un supporto semantico avanzato. Per gli specialisti (co…

Presence of the genus Bythinella Moquin-Tandon, 1856 (Gastropoda, Bythinellidae) and other hydrobioids in Saône-et-Loire (Burgundy, France): taxonomi…

2016

While listing spring-dwelling snails in the regionBourgogne Franche-Comté (eastern France), we found threelocalities with living representatives of the genus BythinellaMoquin-Tandon, 1856 in the department of Saône-et-Loire. Toour knowledge, they represent the only Bythinella -bearinglocalities currently known in this department. The sampledindividuals share several shell features with B. carinulata(Drouët, 1867), B. viridis (Poiret, 1801) and B. lanceleveiLocard, 1884. Pending a complementary genetic analysis, weidentify these specimens as Bythinella sp. Two of the threelocalities also yielded empty shells of Islamia andBythiospeum . They represent the westernmost occurrence ofthese stygob…

Herons of French Polynesia. Threats, status and conservation.

2018

8 pages; International audience; In French Polynesia, only three Ardeidae are present: Cattle Egret (Bubulcus ibis), Tahiti Striated Heron (Butorides striata patruelis) and Eastern Reef-Heron (Egretta sacra), and the last two breed there. The Eastern Reef-Heron is widespread in the Pacific range and its conservation status is least concern. However, the status of the Tahiti Striated Heron is critically endangered on the International Union for the Conservation of Nature Red List. In 2009, only 70 birds were estimated living in Tahiti and thus the entire French Polynesia. Threats are mainly due to the restricted distribution of breeding habitat and habitat destruction. The Tahiti Striated He…

2013

Dans les régions tropicales humides, concilier intensification agricole et protection des ressources naturelles est un défi majeur et difficile à relever. Dans les savanes acides du nord-est laotien, des systèmes de culture de semis direct sur couverture végétale (SCV), basés sur les trois principes du non-labour, d’une couverture permanente du sol, et sur la pratique de rotations culturales diversifiées, sont proposés comme alternative technique à l’intensification agricole conventionnelle basée sur le labour. Si ces systèmes ont connu une diffusion importante et rapide dans les grandes agricultures mécanisées, leur diffusion reste néanmoins à ce jour limitée en contexte de petite agricult…

Agroecology and Strategies for Climate Change

2012

 ; Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion.Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur fro…
