The investigated lake has a circular to squarish shape and covers 1.8 ha. A minor road runs through the catchment area (which is 22 ha) on the western side of the lake (approximately 100 m from the lake shore). The nearest village is situated about 2 km away. Historical maps from the nineteenth century show that cultivated fields and hay meadows were situated close to the village. The maps also show that the immediate area around the lake was part of the land, which was mainly used for grazing and wood resources, and that the nearest hay meadow was approximately 500 m away. Today, the land-cover around the lake is mixed woodland, dominated by spruce plantations. On the western side of the lake catchment is a local nature reserve (Kråketorpsskogen, 200 ha), which is protected from modern forestry.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"61 1","pages":"310 - 313"},"PeriodicalIF":0.9,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44858762","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}

He was involved in agricultural practice and the building of large infrastructure. Florschütz established centres of pollen analysis at the universities in Wageningen (1924) and Utrecht (1928), was appointed professor in Leiden (1948) and after retirement founded a chair in pollen analysis in Nijmegen (1960). The botanical institute in Utrecht was Florschütz’ alma mater where he supervised students over two decades. Since 1947 Florschütz trained micropalaeontologists how to use fossil pollen as a biostratigraphical tool in oil industry. He inspired Jonker in Utrecht and Zagwijn in Leiden. Several of his students focused on tropical areas and used applied and academic pollen analysis to explore tropical ecosystems, such as Polak (1930s) and Muller (1950s) in southeast Asia, Van Zinderen Bakker (1950s) in southern Africa, Van der Hammen (1950s) in northern South America, Van Zeist and Bottema (1960s) in the Middle East. He stimulated Shell to be a pioneer in using pollen-based stratigraphy in oil exploration in the tropics. In the late 1940s and 1950s biostratigraphers Germeraad, Hopping, Kuyl, Muller and Waterbolk studied samples from the Caribbean, Nigeria and British Borneo in Shell’s Pollen Laboratories in Maracaibo (Venezuela) and in The Hague. In 1944 ‘pollen analysis’ was renamed ‘palynology’ for good reasons. Laboratory practice in applied research developed differently from academic palynology leading to a hybrid research field. Implications are briefly discussed.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"61 1","pages":"241 - 255"},"PeriodicalIF":0.9,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47487181","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}

All the pollen grains are trizonocolpate; however, some taxa were observed to have also hexacolpate grains along with trizonocolpate ones. The pollen grains are large, suboblate, less often oblate spheroidal in shape. Distyly is predominantly present in the section, except for homostylous species Linum nodiflorum L. All the studied distylous taxa have dimorphic pollen grains. In short-styled floral morphs, the exine has monomorphic processes, gemmae, which at the top have a ring of marginal papillae, with or without prominent central papilla. In long-styled floral morphs and in homostylous morph, the exine is dimorphic and has two types of processes: bacula, smaller in diameter, ending in a central microechinus, and clavae, larger in diameter with a central microechinus ending into lobes or a ring of scabrae at the margins. In the studied distylous species, the pollen of short-styled morphs is larger than that of the long-styled morphs. Based on the morphometric data, the principal component analysis has grouped these two morphs separately; with the homostylous one, although with dimorphic exine, nested within the short-styled morphs. This could be considered as evidence supporting the loss of heterostyly in homostylous Linum.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"61 1","pages":"256 - 283"},"PeriodicalIF":0.9,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41602412","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 the present study, we identified the pollen types in samples of honey, pollen (nest pots) and pollen baskets of M. mondury workers from a meliponary located in the Atlantic Forest of the state of Bahia, north-eastern Brazil. Samples of flowering plants were also collected monthly nearby the meliponary and from trails along the fragment borders. The botanic material was identified and stored as herbarium collections. The samples of honey and pollen from colonies of M. mondury were collected and prepared using the acetolysis method for palynological studies. Using the botanical inventory around the meliponary, palynological slides were prepared and pollen characterised from 43 genera and 46 species within 24 plant families. Asteraceae (23%), Fabaceae (14%), Anacardiaceae (5%), Myrtaceae (5%), and Melastomataceae (4%) were the most common and diverse families around the meliponary. A total of 44 and 54 pollen morphotypes were found in honey and pollen samples, respectively, comprising several plant families, particularly Myrtaceae (15%) and Melastomataceae (10%). The pollen baskets of workers contained 35 pollen morphotypes, with a predominance of Fabaceae-Mimosoideae (16%), Melastomataceae (13%), Sapindaceae (13%), Myrtaceae (10%) and Solanaceae (10%). The flora of the study area proved to be highly diverse and M. mondury utilises a wide variety of plants, albeit with some differences.

The objective of this study was to evaluate the quality and diversity of fungal propagules in indoor air, specifically in the bedrooms of children with a family history of allergy. The indoor and outdoor air was sampled from 44 bedrooms of children with a family history of allergy during the years 2018 and 2019 in Havana, Cuba. Inside the bedrooms, the presence of humidity problems, visible fungal growth, and the quality of ventilation was examined, while the values of temperature and relative humidity were recorded. Moreover, a distribution analysis of the genera detected was carried out and the Sørensen coefficient of similarity was calculated. In addition, the relationship between the outdoor and indoor air concentrations of each residence was determined. The concentrations of fungal propagules in the indoor air of the bedrooms were between 20 and 1330 colony-forming unit (CFU)/m3. According to the analysed limit values, 18 bedrooms can be classified as having poor indoor air quality. Cladosporium, Aspergillus, Penicillium, and Curvularia were the most frequent genera of the 19 identified in the study. There was a similarity between the indoor and outdoor air mycobiota in 15.9% of the rooms. The detection of these allergenic fungal genera is an alert for children in the sampled homes, mainly for those that were classified as poor indoor air quality according to the examined standards.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"61 1","pages":"284 - 295"},"PeriodicalIF":0.9,"publicationDate":"2022-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41565257","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}

Underground water from a Triassic limestone aquifer feeds the small modern-day Ammer River, which is a tributary of the Neckar River (Schwientek et al. 2013). The climate is humid-temperate with highest air temperatures from June to August (mean 21–24 °C) and lowest temperatures during December to February (mean −1 to 0 °C). The nature reserve Schönbuch north of the Ammer River Valley is characterised by thermophilous and drought-adapted vegetation on south-facing slopes (Arnold 1986). Pleistocene and Holocene sediments cover the Ammer River Valley consisting of brown alluvial clays, Tufa, grey clays, and fluvial and colluvial gravels on top of the Middle Triassic dolostones and mudstones (Geyer et al. 1995; Heidgen et al. 2020; Martin et al. 2020). In addition, the Ammer River Valley is partly covered by nutrient-rich loess deposits. Agriculture dominates today 71% of the land cover and oak, beech, and pine trees are covering hillslopes by ∼12% (Schwientek et al. 2013). Nearby, several archaeological sites have been investigated, such as Neolithic settlements of the Lineare Bandkeramik period (6.3–6.0 cal ka BP), excavated by Krauß et al. (2020), and the Mesolithic archaeological site ‘Rottenburg-Siebenlinden’ (c. 6 km away), which revealed human occupation from 10.1–7.8 cal ka BP (Kind 2010).
