The Sudanian savanna is a key vegetation biome in West Africa providing food and vital ecosystem services. Recently, it has been reported alarming vegetation loss in this biome, calling for more investigation, relevant to tackle land degradation and ensure food security. However, vegetation dynamics in this area remains a matter of debate, and one of the main challenges is to document consistently the underlying driving factors. This study aimed at assessing vegetation trends and driving factors from 2000 to 2022. NDVI trend, detected using the Mann-Kendall’s monotonic trend test, was used as proxy to express vegetation dynamics. In addition to the non-parametric Spearman correlation analysis, variables importance scores, derived from Random Forest (RF) classifications, were used to determine key driving factors among climatic, topographic, edaphic, accessibility and demographic factors. During 2000-2022, no significant trends largely characterised the vegetation cover of the study area. However, patterns of strong (weak) browning and strong (weak) greening affected 7.1% (10.6%) and 12.8% (19.1%) of the study area respectively. According to the driving factors analysis, the observed vegetation trends were mainly driven by rainfall dynamics (trend and mean annual), population growth and anthropogenic activities. The results of this study can support the development of efficient strategies for safeguarding vegetation cover in the Sudanian savanna of Burkina Faso.

Sorghum bicolor is a multi-purpose species adapted to many agroecological zones of Burkina Faso. In the local farming system, different types of sorghum are cultivated together. Such farming conditions could increase gene flow between the different types of sorghum and contribute to the evolution of their main morphological characteristics. Understanding the effect of the farming system on the characteristics of different types of sorghum could contribute to building a strategy for the management of its genetic diversity. A survey and accessions collection was carried out in ten villages selected in two agroclimatic zones of Burkina Faso. A total of 133 accessions were collected and thirty local names were recorded. The results revealed a significant variability within sorghum characteristics based on farmers’ descriptions. Four types of sorghum were identified by farmers based on their uses. These are sweet grain sorghum, grain sorghum, sweet sorghum and dyer sorghum. Most of farmers (54.6%) practised intercropping, and 28.86% of them intercropped several types of sorghum in the same or nearby fields. A high coincidence of the flowering period of the types of sorghum was observed by farmers in both agroclimatic zones. The results also showed that most of the farmers (55.7%) noted changes in the morphological characteristics of different types of sorghum. These variations included the reduction in potential yields and changes in grain taste and colour within the same type. Understanding these variations could help conserve and sustain sorghum genetic resources in Burkina Faso.

With the rupture of the Sangomar spit and climate change, ecosystem functions such as carbon absorption and storage by the Saloum Delta Biosphere Reserve are threatened. Initiatives are carried out as a response to the degradation of the mangrove ecosystem, such as the PRECEMA project. To measure its impact, an assessment of the carbon potential of the mangrove was conducted in 2016 on permanent plots. The present study is part of the monitoring of carbon potential. It aims to contribute to the updating of information on the evaluation of carbon storage potential. The method “afforestation and reforestation of degraded mangrove habitats on a large scale CDM or AR-AM0014 version 04.0” was applied. The mangrove vegetation assessed is dominated by Rhizophora racemosa with 69.9% of the total. With a relatively bushy habit (height = 1.91 m), the height distribution shows a right skewness (Skewness = 2.17; Kurtosis = 4.07) with a tail containing more observations than a normal distribution. The distribution is observed for diameters is skewed with Skewness = 1.5 but Kurtosis = 2.3. Thus the stand is young with an average diameter of 3.90 cm and 79.6% of the trees have a diameter 5 cm. The annual increase in carbon potential of the mangrove has decreased by 80% in 5 years (2016 assessment - 2021 assessment). For a 15-year period, the total carbon stock projected by the model increases globally from 201.396 TeqCO2 in 2011 to 277,318 TeqCO2 in 2026. The projections showed an overall annual stock decrease of 14,164 TeqCO2 (94%). For 2021, the total projected stock (270.289 TeqCO2) is slightly higher than the assessed stock (251.059 TeqCO2), a difference of 7%. Also, the projected annual carbon stock for 2021 (2844 TeqCO2) is higher than the assessed stock (1353 TeqCO2), a gap of 52%.
随着桑格玛河口的断裂和气候变化，萨鲁姆三角洲生物圈保护区的碳吸收和储存等生态系统功能受到威胁。为了应对红树林生态系统的退化，采取了一些举措，例如PRECEMA项目。为了衡量其影响，2016年在永久地块上对红树林的碳潜力进行了评估。本研究是碳势监测的一部分。它的目的是促进更新关于评价碳储存潜力的资料。采用“大规模CDM或AR-AM0014 version 04.0对退化红树林生境进行造林和再造林”方法。红树林植被以总状根菌(Rhizophora racemosa)为主，占69.9%。相对浓密的习性(高度= 1.91 m)，高度分布呈右偏度(skewness = 2.17;峰度= 4.07)，其尾部包含比正态分布更多的观测值。直径的分布呈偏态，偏度为1.5，峰度为2.3。平均林分直径为3.90 cm, 79.6%的林分直径为5 cm。红树林碳潜力的年增长率在5年内(2016年评估- 2021年评估)下降了80%。在15年期间，该模型预测的全球总碳储量将从2011年的201.396 TeqCO2增加到2026年的277,318 TeqCO2。预测显示，总库存量每年减少14164 TeqCO2(94%)。2021年，预计总库存量(270.289 TeqCO2)略高于评估库存量(251.059 TeqCO2)，相差7%。此外，预计2021年的年碳储量(2844 TeqCO2)高于评估的储量(1353 TeqCO2)，差距为52%。

The study was conducted with the main objective to evaluate the genetic variability, heritability, and clustering pattern exploration of morphological and yield related traits in potato (Solanum tuberosum L.) collections in the bimodal rainfall agroecological zone of Cameroon using a Randomized Complete Block Design (RCBD) with three replications. The data obtained on morphological and yield traits were subjected to analysis of variance (ANOVA). The results showed that the viability rate of the collections varied from 77.78% to 96.55% respectively for the Maffo and Desiree collections, while the greatest number of tubers per plant varied from 4 to 18 respectively for Synergie and Desiree. The emergence rate varies from 60% to 1.66% respectively for Maffo et Doza collections. However, Desiree presents the highest TL (96.55) while Maffo shows the lowest value (77.78%). The yield per hectare varied from 1.14 to 9.3 t/h for Maffo and Doza respectively. For all the characteristics observed, Phenotypic Coefficients of Variation (PCV) were higher than Genotypic Coefficients of Variation (GCV) suggesting the role of environment in the expression of traits under observation. The highest GCV and PCV 47.55 and 58.94 respectively were observed for Diameter at the collar (DC). Most of the traits showed high GAM (>20%)) except Average Tuber Length (ATL) with a moderate value (19.8). In terms of vegetative development, the Desiree variety showed the highest performance. Based on the growth and yield results, Doza seems to be the most recommendable crop in the study area.

The Dipterocarpaceae family is famous for timber productions in Southeast Asia. The Shuangxi tropical arboretum in Taiwan introduced some dipterocarp species in 1935. However, the changes in abundance and regeneration of each dipterocarp species are unknown. This study aimed to investigate their diameters patterns and regeneration ability over a long period. The results showed that only four dipterocarp species were survived in this arboretum. An individual plant of Dipterocarpus gracilis Blume had a diameter of 5.7 cm. A young seedling was 90 cm in height, and some fruits germinated directly on the ground. A few fruits of Dipterocarpus grandiflorus (Blanco) Blanco were collected; however, and no seedlings have been found thus far, and its annual growth rate was 2.82% as the fastest growth speed. The annual growth rate of Rubroshorea polysperma (Blanco) P. S. Ashton & J. Heck was 2.32%, which is the second growth speed among the different species. Moreover, the abundance of R. polysperma increased as the fruits germinated. In particular, an uneven-aged forest of R. polysperma was established near the southwest area of the No. 2225 nature conservation protection forest, and an individual with a 100 cm DBH was also found. The fruits of Rubroshorea palosapis (Blanco) P. S. Ashton & J. Heck. could not be collected, but a young seedling appeared, with a height of approximately 150 cm. Therefore, Taiwan should be considered as the new distribution site for the Dipterocarpaceae family, all four dipterocarp species can grow in this area and need to be protected carefully.
龙掌科在东南亚以木材生产而闻名。台湾双溪热带植物园于1935年引进了一些双龙脑属植物。然而，各双龙果树种类的丰度和再生变化尚不清楚。本研究的目的是研究它们的直径模式和长时间的再生能力。结果表明，该树种仅残存4种双龙果。梁木单株直径为5.7 cm。幼苗高90厘米，有些果实直接在地上发芽。收集了桔梗(Dipterocarpus grandflorus (Blanco) Blanco)的几个果实;但至今未发现苗木，年生长率最高，为2.82%。多精毛藻(Rubroshorea polysperma, Blanco) P. S. Ashton & J. Heck的年生长率为2.32%，在不同种中排名第二。随着果实的萌发，多精孢子的丰度也随之增加。特别是在2225号自然保护保护林的西南附近，发现了多精草的不均匀年龄林，并发现了一个胸径为100 cm的个体。P. S.阿什顿和J.赫克。无法采集，但出现了一株幼苗，高约150厘米。因此，台湾应被认为是龙脑科的新分布区，4种龙脑科植物均可在此生长，需要谨慎保护。

Seed dispersion reduces the depredation rate and increases genetic flow. Some species of Carnivora consume fruits as a standard component of their diet, so they become potential seed dispersers. In Mexico, a few studies evaluated carnivorous as seed dispersers, especially in dry ecosystems. Citharexylum tetramerum and Ziziphus pedunculata are endemic plants from the Tehuacán-Cuicatlán’s Biosphere Reserve (TCBR); however, there are very little data about dispersal seeds for both species. We assessed the germination of seeds ingested by carnivores obtained from feces. We compared them with seeds from fruits as a control group. At the Metropolitan University laboratory, we germinated seeds, from: plants, scats, and fruits, and we used Kruskall Wallis Test to compare percentage and germination rate. C. tetramerum seeds ingested by a carnivorous decreased in germination percentage and rate. In contrast, the percentage and rate of germination of Z. pedunculata seeds from carnivorous feces were higher than the control group. However, Z. pedunculata control seeds did not germinate during tests, but at the end of the tests, we found that 90% of control seeds were not dead, so they were dormant seeds. Carnivores interact as legitime dispersers for both plants because they are keeping the viability of seeds. Still, we only showed that Z. pedunculata gut carnivores broke with the dormancy of seeds. We consider that in future research, it could be essential to identify other animals that consume fruits of those plants and if it is possible to follow seeds after they have been removed. Those points could help to get better understanding of those endemic plants from Tehuacán.

Field experiments were conducted at Gore near Zebila in Bawku West District of the Upper East Region of Ghana during the 2015 and 2016 cropping season on four Striga tolerant maize varieties in maize/soybean integration alongside maize monocrop as a means of managing the devastating effects of Striga. The study determined the relative Striga tolerance of the maize varieties in terms of yield and yield components, as well as the most effective intercrop for the reduction of Striga seed bank. The treatment differences were not significant (p Striga count and Striga biomass. Similarly, yield components of maize such as height of cob attachment, cob length, cob weight, 100 seed weight, grain yield, as well as straw weight were not significantly affected by the treatments. There was no relativity of Striga stress tolerance in terms of yield and yield components of the four maize varieties. All the entries efficiently tolerated the biotic stress of Striga and further supported growth and grain yield equally. There was reduced S. hermonthica seed bank production in the soil in both cropping systems. The four maize varieties are proven tolerant materials to Striga infestation and are therefore recommended for long-term Striga seed bank depletion in the study area.

Ferula L. is a perennial herbaceous plant belonging to the family Apiaceae Lindl. (Umbelliferae). Our research was carried out on the territory of Navoi region. The article presents an ecological analysis of the species of the Ferula L. in Navoi region. The species of genus Ferula mostly grows in mountainous regions and some are distributed in arid climates. According to that 15 species of the genus were found in the Navoi region, most of these species are considered to be plants that contain tar as well as have a strong medicinal property. In various parts of the world, different species of Ferula have been used in traditional medicine. In the course of studies, it was found that the species has medicinal, essential-oil, honey-juicy, nutritious, and fodder properties. According to ecological analysis, the genus Ferula grows Rocky, gravelly, fine-grained slopes and ridges of mountains, scree, rocks, outcrops of variegated rocks, rocky slopes, sandy, clay and gravelly deserts, foothill plains, fine-grained slopes. Considered rare, Ferula kyzylkumica Korovin is listed in the Red Book of the Republic of Uzbekistan, while Ferula nuratavica Pimenov is an endemic plant of the Aktau ridge.
