The potential of the vegetation to sequester C is determined by the balance between assimilation and respiration. Respiration is under environmental and substrate-driven control, but the circadian clock might also contribute.

Beside their potential for carbon sequestration, compost and biochar application in agriculture may constitute an alternative to mineral fertilizers by improving soil fertility and productivity in carbon-poor soils. This study focused on the impact of biochar and compost produced from date palm residues on nitrogen (N) leaching and plant uptake in a sandy soil cultivated with barley under arid climatic conditions. In addition to the unamended control soil (S), treatments with biochar (BC), urea (U), biochar + urea (BCU), compost (C) and biochar + compost (BCC) were tested. We followed soil fertility parameters, N leaching losses, N uptake and plant growth. Results showed a significant increase of barley yields with compost compared to urea (+66 %) treatment (U), biochar amended (BC) and unamended soil (S). Biochar alone or coapplied with a nutrient source seems to reduce barley shoot biomass and grain yields at shortterm. Leachate N recovery and soil extractable inorganic N at the end of barley cultivation indicated that compost did not provide N in excess at barley maturation stage. Compost amended soils led to the highest N losses through leaching and thus environmental risk of N vertical transfer. However, compost had positive effects on soil nutrient status and barley yields. No synergistic effect was observed between biochar and compost. In conclusion, this paper highlights that date palm compost improved barley productivity in a coarse textured soil, but with very short-term effects concerning available soil N.

Semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha) are predatory insects that occupy a wide range of freshwater and marine habitats, with some secondary transitions to terrestrial life. They currently represent more than 2100 species distributed through all continents, except for Antarctica, and are especially rich in the Neotropical and Oriental regions. Although the fauna from the former region is relatively well known, some areas remain almost unexplored. Such is the case of French Guiana, where only a few species have been previously recorded, several of which based on collections made in the 19th and early 20th centuries. As a result of material recently collected in the territory, the descriptions of Rhagovelia depressa Rodrigues, Khila & Moreira, sp. nov., R. tantilloides Rodrigues, Khila & Moreira, sp. nov. and Steinovelia vittata Rodrigues, Khila & Moreira, sp. nov. (Veliidae) are presented here. New records for 28 species are also provided, of which Cylindrostethus hungerfordi Drake & Harris, 1934, Neogerris magnus (Kuitert, 1942), Rheumatobates mangrovensis (China, 1943), R. trinitatis (China, 1943), Ovatametra obesa Kenaga, 1942, Telmatometra fusca Kenaga, 1941, T. parva Kenaga, 1941 (Gerridae), Mesovelia amoena Uhler, 1894 (Mesoveliidae), Rhagovelia brunae Magalhães & Moreira, 2016, R. elegans Uhler, 1894, R. ephydros (Drake & Van Doesburg, 1966), R. equatoria D. Polhemus, 1997, R. evidis Bacon, 1948, R. guianana D. Polhemus, 1997, R. tenuipes Champion, 1898, Oiovelia cunucunumana (Drake & Maldonado-Capriles, 1952), Stridulivelia alia (Drake, 1957), S. stridulata (Hungerford, 1929), and S. tersa (Drake & Harris, 1941) (Veliidae) are reported from French Guiana for the first time.

#CNRS #FORET NouraguesRésumé
Neacomys is a genus of small spiny or bristly sigmodontine rodents that are common components of mammalian faunas in multiple biomes on Central and South America. Recent studies on this group have demonstrated that there is cryptic diversity yet to be discovered within currently recognized species that have not received comprehensive revisions, as well as in areas that have been overlooked. Here we ratify this assertion by describing a new species previously misidentified as the Narrow-footed Spiny Mouse (Neacomys tenuipes) from the Chocó biogeographic region in northwestern Ecuador, Neacomys marci Brito & Tinoco, sp. nov. Distinctiveness of this entity is supported by the combination of the following morphological characters: small size (head-body length 65–85 mm); long tail (69–126% longer than head-body length); pale buff-colored but gray-based belly fur; white throat; hypothenar pad usually absent; long nasals; and a condylar process higher than the coronoid process. Likewise genetic distance analyses and phylogenetic reconstructions based on cytochrome-b (Cytb) sequence data indicate a clear divergence from typical populations of N. tenuipes, and a sister relationship between them. The results presented here increase the diversity of Neacomys to 24 species, placing it among the most diverse genera within the sigmodontine rodents.
