Apple trees in agroforestry – Investigating the plasticity of vegetative and reproductive traits. Mediterranean area of France during 2018 to 2023
No full textAgroforestry is promoted as a way to improve the sustainability of horticultural systems through plant diversification and also to mitigate climate change through carbon sequestration. It could also alleviate excessive light and temperature in high-radiation regions of the world. However, little is known about the long-term shade adaptation of the temperate fruit tree in agroforestry systems. A study was developed to investigate apple growing under walnut trees in two shade conditions compared to a full light condition. Our aim was to quantify the plasticity of traits and the covariations between traits in these three light conditions using a multiscale approach considering different scales from whole tree to annual shoot and inflorescence. Shade did not affect the height of the apple trees, while it reduced the diameter of the trunk and branches. On the other hand, the total number of growing shoots was reduced in shade, and flowering and fruiting were fewer and more irregular than in full light. Strikingly, at the whole tree scale, covariations between vegetative traits (trunk cross-sectional area versus mean branch cross-sectional area) and between vegetative and reproductive traits (trunk cross-sectional area versus total number of inflorescences) were not altered by shade. However, at the shoot scale, return-bloom was significantly reduced by shade, whereas at the inflorescence scale shade did not affect leaf number or leaf area. We propose a shade adaptation syndrome that includes not only shade intensity but also shade dynamics during the growing season and over consecutive years, in mediterranean area of France during 2018 to 2023

Morphometric data of insectivorous bat communities in two caves of The Republic of Congo
No full textThis dataset includes the morphometric data of all the individuals measured as part of my thesis project in the Republic of Congo. The captures were made in two caves: the Mont Belo cave and the Boundou cave. It includes 7 different bat genera: Rhinolophus, Miniopterus, Hipposideros, Triaenops, Macronynectis, Roussetus and Coleura.
Each individuals captured was photographed, measured for its morphometric characteristics, reproductive status, sex and identification at least to the genus.
For each bats captured, M.L measured the following morphological indicators :
WT : weight of an individual in grams ;
FA: forearm length ;
WS : wingspan between wing tips in straight line ;
HB : length of head and body from tip to anus ;
TL : total length from tip of snout to posterior and of tail ;
T : tail length from tip to anus ;
E : length of ear from notch to tip ;
Tib : the length from top of knee to base of ankle when both knee and ankle are bent ;
HF : length of hindfoot from heel to tip if longest claw.
In supplement for Rhinolophus, Triaenops and Hipposideros genus with measured NL breadth (the maximum breadth of the noseleaf) and NL length (the length of the noseleaf) and for Miniopterus genus, we measure the length of tragus (usually from tip to junction of posterior margin with the ear (Tr).
We used a dial caliper for the measurement of FA, a tape measure for WS and HB, a ruler for T, E, Tr, Tib, HF, NL breadth and NL length and a Pesola balance of 100g to weigth bats

Sensory and instrumental acceptance thresholds of pounded yam stretchability/extensibility by UAC-FSA, Bénin
No full textA main quality attribute of pounded yam is its extensibility/stretchability, with yams exhibiting high values being preferred by consumers. This study assessed the sensory and instrumental acceptance thresholds of stretchability through consumer testing, quantitative descriptive analysis (QDA), Kieffer dough extensibility and dynamic rheology analyses performed on twenty varieties in two experiments. Significant differences were evidenced among yam varieties for all studied parameters. Furthermore, stretchability was predicted by instrumental extensibility by Kieffer dough method (R2 = 0.61) or G’-G” crossover (R2 = 0.77). A high stretchability is preferred by consumers, with the desirable sensory score above 8.01, on a 10 cm unstructured line scale, corresponding to biophysical targets values above 3.38 mm for kieffer dough extensibility (distance while stretching using texturometer) and below 1.52 kPa for G’-G” crossover (using rheometer). Thus, Kieffer dough textural or dynamic rheology analyses are practically relevant in understanding the extensibility of pounded yam, and can be carried out to screen the various yam genotypes and determine textural thresholds for pounded yam extensibility

Dataset on the parameters studied from promising yam genotypes in Benin
No full textBoiled yam quality traits mainly includes white color, sweet taste and the crumbly texture. The latter, as a key trait for boiled yam acceptance, is highly variety dependent. The study aimed at classifying yam genotypes regarding their crumbliness for boiled yam. Ten (10) landraces and 23 hybrids were used among them nine were harvested in two zones (Bassila, Dassa, Djougou Massi). Consequently, 42 samples were considered for this study. Textural analysis as well as dry matter content were carried out. In addition, some of the genotypes (nine) were subjected to quantitative descriptive analysis (QDA). The textural parameters, the dry matter content of yam and the sensory crumbliness of boiled yam enable discriminating the genotypes (p-value <0.0001). Using predicted crumbliness based on textural parameter LDPeak/APeak and the sensory thresholds of boiled yam, yam genotypes were classified in good (9 genotypes), medium (13 genotypes) and bad (20 genotypes) quality clusters for boiling. This classification was used to identify yam genotypes which are promising (good and medium). However, further investigations have to be done for a better understanding of the crumbliness of boiled yam which is not yet well mastered since only 36% of sensory crumbliness was explained by the predicted crumbliness

Body Condition Scoring Grid for Buffaloes (Vietnam)
No full textIn tropical countries subject to significant quantitative and qualitative variations in the availability of fodder during the year, the dissatisfaction of feed needs is a frequent situation for animals raired in grazing systems without a sufficient supplementation with feed concentrates.
The Body Condition Scoring (BCS) is a useful way to assess the state of body reserves (subcutaneous fat, muscle mass) which reflects the animal's production (growth, milk, work) and reproduction capacities. The evaluation of the body reserves of an animal through the scoring of their body condition is important to adjust their diet and appreciate their general state of health, as well as their reproductive and production capacity (meat, milk, work, etc.). Managing body reserves is one way of responding to variability in quality and access to feed resources. In females, reserves play an important buffer role during lactation. They can make up for insufficient intakes from the ration. Indeed, the level of production depends on the nutrients provided by the feeds, but also on the animal's body reserves when the feed-based supplies do not fully cover their needs, especially during the dry season. The BCS impacts the interval between two calving. Overly lean cows show a delay in the return of heat after calving, the direct consequence of which is the increase in the parturition interval and consequently a decrease in herd productivity.
The assessment of these reserves through Body Condition Scoring (BCS) represents a management tool for livestock farmers, agricultural advisors and livestock development stakeholders. BCS is a simple, inexpensive and fast method. Several animals can be scored in one session. It allows to compare the BCS of individuals or herds: 1) raised in different production systems or environments, 2) or, during different seasons (dry season and rainy season). BCS can be used as a tool for monitoring and alerting the nutritional level of domestic animal populations. To do this, BCS alert thresholds and a BCS collection and monitoring system must be defined on reasoned samples of animal populations.
It is an easy-to-use field tool. However, a good mastery of the BCS grid as well as a regular practice of scoring are necessary to obtain precise and reproducible ratings. It can also be used as a tool for monitoring and alerting the nutritional level of animal populations. Thus, the farmer can be called at any time to intervene on the feed ration and / or the health of the animal.
The BCS grid currently used in the intervention area of the Beef Cattle 2 project, does not seem to have been developed with reference to the breeds of buffaloes present in Northern Vietnam. This is the reason why we propose this BCS grid adapted to Buffaloes (Bubalus bubalis).
In 2020, Vall proposed a standardized BCS scoring system for tropical livestock animals for large animals (cattle, camels), small animals (sheep, and goats) and for donkeys, and horses. This document presents this BCS system applied to the Buffalo
