Abstract In agroforestry systems, shade trees strongly affect the physiology of undergrown crop. However, a major paradigm is that reduction in absorbed photosynthetically active radiation is, to certain extent, compensated by an increase light‐use efficiency, thereby reducing difference net primary productivity between shaded and non‐shaded plants. Due large spatial heterogeneity systems lack appropriate tools, combined effects such variables have seldom been analysed, even though they may...
Abstract This data paper presents observations on soil organic carbon (SOC) gravimetric and volumetric contents (SOCg, in g kg −1 , SOCv, dm −3 respectively) for 98 profiles at least 30 cm deep (1 m 59 of them), rural areas the Martinique island, relation to types land uses management. The also particle size distribution down cm, near infrared reflectance (NIR) spectra main types. dataset allows evaluating effects use, type texture SOC content stock, regional scale. It inferring SOCg, SOCv...
Particle size fractionation enables a better understanding of soil organic carbon (C) dynamics since it separates fractions that differ in composition, residence time and function. However, this method is time-consuming tedious; thus, its use has been greatly limited. Our objective was to evaluate the ability an existing spectral library (SSL) from different regions West Africa predict C amount (gC kg−1 soil) samples new target set Benin. The SSL included 181 five countries, 94 (depth ≤ 40...
Abstract Main conclusion Emblematic Vachellia spp. naturally exposed to hyper-arid conditions, intensive grazing, and parasitism maintain a high nitrogen content functional mutualistic nitrogen-fixing symbioses. AlUla region in Saudi Arabia has rich history regarding mankind, local wildlife, fertility islands suitable for leguminous species, such as the emblematic desert trees. In this region, we investigated characteristics of legumes two nature reserves (Sharaan Madakhil), at one...
Analyses of environmental correlates the composition gastrointestinal parasite communities in black howler monkeys (Alouatta pigra) have been hindered by inadequate calibration techniques detection and quantification methods parasites. Here we calibrate samples compare likelihood using two flotation techniques, FLOTAC Mini-FLOTAC, solution, preservation method dilution ratio for egg counts most common parasites (Controrchis spp. Trypanoxyuris spp.) monkeys.For preserved 5% formalin,...
There is increasing demand for data on soil organic carbon (SOC) stock (SSOC; kgC m−2), but the acquisition of such data, which relies determination volumetric SOC content (SOCv; gC dm−3), often tedious or complex. Visible and near infrared reflectance spectroscopy (VNIRS) has proven useful characterization, rarely been used direct prediction SOCv. The objectives this work were: (i) to compare SOCv predictions using VNIR spectra collected in situ vs. 2-mm sieved air-dried (laboratory...
Abstract In coffee, fruit production on a given shoot drops after some years of high yield, triggering pruning to induce resprouting. The timing is crucial farmer’s decision affecting yield and labour. One reason for drop could be the exhaustion resources, particularly non-structural carbohydrates (NSC). To test this hypothesis in Coffea L. arabica agroforestry system, we measured concentrations NSC, carbon (C) nitrogen (N) leaves, stems stumps coffee plants, 2 5 pruning. We also compared...
L’urbanisation est aujourd’hui en France la premiere cause de changement d’usage des sols qui sont encore consideres comme surfaces a consommer et non ressources preserver. Ainsi, surface artificialises atteint desormais pres 10 % du territoire metropolitain. Le stockage carbone organique dans ces urbains primordial car il determine nombreux services ecosystemiques essentiels au bien-etre citadins. Cet article expose les resultats scientifiques obtenus lien avec cette thematique limites...
