In sub-Saharan Africa, crop pest control mainly involves synthetic pesticide applications based on a treatment calendar consisting of 5–6 applications at 14-day intervals. Organic cotton production chains have however been set up to supply a niche market, with botanical extracts used for crop protection. This review presents published results of experiments conducted in sub-Saharan African countries. A total of 37 plant species were laboratory tested in research stations (24 trials) and village fields in Central and West African countries. Neem (Azadirachta indica) was the plant most commonly used in the form of seed-pressed oil. In Mali, this compound was combined with Carapa procera oil in organic cotton cropping conditions. Cassia nigricans is another species reported to be used in Mali, Burkina Faso and Benin. Aromatic species such as Ocimum gratissimum, Cymbopogon citratus, Citrus sp. were also tested. Further research could focus on species such as Anacardium occidentale and Hyptis suaveolens, which seem to be locally available. The use of essential oils does not appear to take priority over aqueous extracts, which could be tested in crop protection programmes involving partial substitution of synthetic insecticides.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49234814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technique allows for a consecutive analysis of individual grains by means of light microscopy and Scanning Electron Microscopy (SEM). The current study demonstrates the occurrence of diverse lineages of palynomorphs comprising algae, spores and pollen. So far 45 different types of palynomorphs were analysed, illustrated and wherever possible assigned to families encompassing chlorococcalean and zygnematalean algae, ferns, gymnosperms and angiosperms. The latter group was the most diverse one among the analysed palynomorphs. The palynomorphs described in this study represent only a small, non-representative selection of palynomorphs that occur in the palynoflora of the maar lake from Menat, and hence more effort is expected to be done in the future. However, the data and interpretations presented here are preliminary ones, they could help to understand and refine our knowledge about the palaeoflora and palaeoenvironments of this important locality and fossil archive, as well as their development through time.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45029532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two genera Virgatasporites and Attritasporites, described in the 1960ʹs from the Early Ordovician (Tremadocian) of Algeria, are morphologically close to the miospores, and therefore pose a dilemma, because these spore-like microfossils are recorded before the first appearance of the oldest land plant derived spores. Here the taxonomy, biostratigraphy and palaeobiogeography of the two genera and their species are revised. Both genera are found in many localities on the Gondwanan border between the late Cambrian and the Middle Ordovician. They have not been found at the margins of other palaeocontinents so far. The biological affinity of the taxa remains uncertain. Several authors considered the two genera to be spore-like microfossils, whereas other authors classified them as acritarchs, i.e. organic-walled microfossils of unknown biological affinity. As the relationship to the embryophyte lineage cannot be established clearly to date, the biological affiliation remains enigmatic. Therefore, in the absence of other evidence, the taxa Virgatasporites and Attritasporites should be temporarily classified as incertae sedis, i.e. as acritarchs, before their true biological affinity is known and they can be adequately placed into a biological group.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42750364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying the extant plant specimens from this period can give us valuable insights into how scholars approached the science of botany. Several dried plant specimens in the 18th-century Van Royen collection kept at Naturalis, Leiden, have at one time been recognised as originating from Herman Boerhaave (1668–1738). The aim of this study is to establish which specimens come from Boerhaave and try to answer the question why relatively few of these survived. We verified which specimens came from Boerhaave and updated the existing identifications of 88 specimens. We studied the way the specimens were mounted, the handwritings on the various labels and the use of decorations. We taxonomically identified them and linked the accompanying labels to the seed register of the Leiden Hortus Botanicus, where these specimens originated from. The transcription of the labels provided us with valuable information about the introduction and cultivation of indigenous and exotic, predominantly Mediterranean, plant species. Little effort has been put into connecting the contribution by Boerhaave with the living collection of the Leiden Hortus botanicus at the time, that is, the herbarium specimens we now know to have been described by Boerhaave. By studying these specimens we made his contribution visible.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44685717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many mega faunal taxa having become extinct with time, the species seems to have adapted to its changing environment by ensuring the dispersal of its seeds by alternative dispersers. The present investigation reports the mechanism of seed dispersal adopted by individuals of K. africana grown in India, outside the species natural environment. The massive – ~2.0 kg – indehiscent and unattractive fruits retain the wingless seeds. Of more than 300 seeds present in a fruit in average, approximately 92% remained viable at maturity, and the viability decreased over time after 1 year. We observed that numerous termites (Coptotermes formosanus) initiated the disintegration of the fallen fruits particularly during monsoon. Three-striped squirrels (Funambulus palmarum), classified as scatter hoarding rodents, then accessed these fruits and their seeds, and actively carried about 48% seeds with broken coats to a distance of 40 m away from the mother trees. The coordinated activity of these two dynamic vectors ensured successful seed dispersal in K. africana at the study site, suggesting that the species may have developed a way to adapt to its new environment.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46917941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we reassess an assemblage collected in the 1930s in the Rebreuve quarry (Pas-de-Calais, northern France). We describe new features in several taxa and update taxonomic names from original descriptions. For instance, re-examination of vegetative remains previously described as Psilophyton princeps, led to the discovery of fertile structures allowing us to refer these specimens to Sawdonia. In total, this flora consists of 10 taxa, including up to four different Psilophyton species, such as P. parvulum. Other taxa include Danziella artesiana, Drepanophycus cf. spinaeformis, Sporogonites exuberans and some specimens of Taeniocrada and Sciadophyton, revealing a diverse Lower Devonian plant assemblage. The Rebreuve assemblage represents a typical Emsian flora from Laurussia and bears striking resemblance with coeval Belgian assemblages. Previous palynological investigations, in addition to the similarities with well-dated Belgian floras, suggest an early Emsian age for this assemblage. The paleogeographical implications of findings are discussed.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45211165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
