Abstract:
The present paper deals with spatial and temporal distribution of pteridophytic megafossils within Palaeozoic plant bearing horizons of India. An attempt has been made to describe the pteridophytic assemblages in various strata of different ages, dynamism of the relative dominance pattern of various types of pteridophytes within each assemblage vis-Ã -vis the environment they lived in. Critical discussion has been done regarding increasing diversity of Palaeozoic pteridophytic taxa, taxonomic riddles, plant architecture, ecological analysis and phylogenetic implications. Special attention has been given to the floristic regionalism of Lower Carboniferous flora of India in reference to the world palaeophytogeography and occurrence of admixture of Cathaysian, Euramerian and Gondwana pteridophytic elements in palaeoecotone zone near the northwestern boundary of Indian Gondwana Plate.

Abstract:
The district Cooch Behar, located in the north-eastern part of West Bengal, at the foothills of Eastern Himalayas, is very rich in pteridophytic flora. The present field study was undertaken during January 2021 to September 2022 to explore and document the epiphytic pteridophytic flora of the district and their ethnomedicinal uses, which was not previously done. Standard methods for plant specimen collection and herbarium techniques were followed and identification was done with the help of relevant sources. Altogether 14 epiphytic species of pteridophytes comprising 10 genera and six families were recorded. Polypodiaceae was the dominant family represented by eight species (57.14 %) and is dominated by the genus Pyrrosia (five species; 35.71 %). With the help of pretested semi-structured questionnaires, knowledgeable ethnic people and traditional healers of the studied areas were interviewed to record their traditional knowledge on pteridophytes. Out of 14 recorded species, 12 species were used by the ethnic communities and traditional healers to treat 15 different types of diseases ranging from common cough and cold to jaundice, among others. Leaves were found to the dominant plant part (58.82 %) used for the preparation of ethnomedicine. Decoction (52.94 %) of the plant parts were mostly used as herbal medicine and were frequently taken orally (58.82 %). Exploration of epiphytic pteridophytic flora and their utilization as ethnomedicine by the ethnic people has been scientifically documented for the first time from Cooch Behar district and has enriched the existing database our country.

Abstract:
The state of Gujarat physiographically comprises three distinct zones–the Gujarat Mainland, the Saurashtra and the Kachchh. The sedimentary deposits of Himmatnagar Sandstone (23°36'00": 72°57'45") are mainly exposed in Gujarat Mainland. Palaeobotanical study reveals occurrence of plant fossils Matonidium, Weichselia, Cladophlebis, Gleichenia, Sphenopteris, Dictyophyllum, Pachypteris, Pagiophyllum and Araucarites. Bennettitales are absent. Numerically pteridophytes are represented by 61%, pteridosperms are represented by 7% and cyacads are represented by 7% while conifers are represented by 24%. The assemblage is compared and correlated with contemporaneous deposits in India and other Gondwanic continents and found that it is coeval to fossil floral assemblage of Dharangdhara Formation, (Saurashtra) and Bansa Formation of South Rewa (in central part of India) and Athgarh Formation on east–coast of India, in having common occurrence of Wealden frond Weichselia with dominance of pteridophytic fronds and conifers of family Araucariaceae. Due to common occurrence of pteridophytes and conifers (at generic level) the flora also resembles to Bluff flora of Alexander Island (Antarctica) and Barcó flora of Baqueró Formation of Patagonia (South America) indicating that the dispersal of biota might have taken place through Kerguelen Plateau or Gunners ridge via Antarctica.

Abstract:
Marine Inseln beherbergen einen großen Teil der biologischen Vielfalt unseres Planeten und weisen gleichzeitig einen hohen Anteil endemischer Arten auf. Inselbiota sind allerdings zudem besonders anfällig für anthropogene Einflüsse wie den globalen Klimawandel, Habitatverlust und invasive Arten. Für ihren Erhalt ist es daher wichtig, die ökologischen Prozesse auf Inseln detailliert zu verstehen. Aufgrund ihrer definierten Größe und isolierten Lage eignen sich Inseln als Modellsysteme in der ökologischen und evolutionären Forschung. Der Großteil der bisherigen Inselstudien hat sich allerdings mit kleinräumigen Mustern befasst, so dass standardisierte globale Daten zu den biogeographischen Eigenschaften und eine makroökologische Synthese ihrer Biota bislang fehlen. In dieser Arbeit stelle ich eine physische und bioklimatische Charakterisierung der Inseln der Welt vor und behandle die Frage, wie abiotische Inseleigenschaften die Diversität von Inselfloren beeinflussen. Ich bearbeite zwei Hauptaspekte dieser Fragestellung: Zuerst konzentriere ich mich auf historische und heutige Klimabedingungen und physische Inseleigenschaften als Triebfedern von Pflanzendiversitätsmustern auf Inseln. Hierbei setze ich einen Schwerpunkt auf die räumliche Anordnung von Inseln und Struktur von Archipelen. Als Zweites behandle ich taxon-spezifische Unterschiede in der Antwort von Diversitätsmustern auf abiotische Faktoren. Hierzu stelle ich eine globale Datenbank mit historischen und heutigen Klimabedingungen und physischen Eigenschaften, wie Fläche, Isolation und Geologie, von 17883 Inseln größer als 1 km² vor. Mit Hilfe von Ordinations- und Klassifikationsverfahren charakterisiere und klassifiziere ich die Inseln in einem multidimensionalen Umweltraum. Außerdem entwickele ich einen Satz von ökologisch relevanten Maßen zur Beschreibung von Isolation von Inseln und ihrer räumlichen Anordnung in Archipelen, darunter Maße zu Trittstein-Inseln, Wind- und Meeresströmungen, klimatischer Ähnlichkeit, Distanzen zwischen Inseln und umgebender Landfläche. Diese Maße berücksichtigen verschiedene Aspekte von Isolation, welche Immigration, Artbildung und Aussterben auf Inseln sowie Austausch zwischen Inseln beeinflussen. Um abiotische Bedingungen mit biotischen Eigenschaften von Inselfloren in Verbindung zu bringen, nutze ich eine für diese Arbeit erstellte Datenbank aus 1295 Insel-Artenlisten, die insgesamt ca. 45000 heimische Gefäßpflanzenarten umfassen. Dies ist der umfassendste und erste globale Datensatz für Pflanzen auf Inseln, der Artidentitäten anstatt lediglich Artenzahlen beinhaltet. Die globale Insel-Charakterisierung bestätigt quantitativ, dass sich Inseln in bioklimatischen und physischen Eigenschaften vom Festland unterscheiden. Inseln sind im Durchschnitt signifikant kühler, feuchter und weniger saisonal geprägt als das Festland. Die weiteren Ergebnisse zeigen, dass eine sorgfältige Beschreibung der räumlich-physischen Eigenschaften von Inseln und Archipelen nötig ist, um die Diversitätsmuster ihrer Biota zu verstehen. Isolation ist nach Inselfläche der zweitwichtigste Einflussfaktor für den Gefäßpflanzenartenreichtum auf Inseln. Von den verglichenen Isolationsmaßen eignet sich der Anteil an umgebender Landfläche am besten zur Erklärung der Artenzahlen. Außerdem erhöht sich durch die Berücksichtigung von Trittsteininseln, großen Inseln als Quell-Landflächen und klimatischer Ähnlichkeit der Quell-Landflächen die Vorhersagekraft der Modelle. Isolation spielt eine geringere Rolle auf großen Inseln, wo in situ Diversifizierung den negativen Effekt von Isolation auf Immigration ausgleicht. Die räumliche Struktur innerhalb von Archipelen ist von besonderer Bedeutung für β-Diversität, d.h. für den Unterschied in der Artenzusammensetzung der Inseln. Außerdem beeinflusst sie indirekt, durch den Effekt auf die β-Diversität, auch die γ-Diversität, d.h. die Diversität des gesamten Archipels. Die Ergebnisse heben die enorme Bedeutung der relativen räumlichen Position von Inseln zueinander für Diversitätsmuster auf Inseln hervor und zeigen die Notwendigkeit für Inselforschung und Naturschutz, Inseln im Kontext ihres Archipels zu betrachten. Die Ergebnisse für Farne auf südostasiatischen Inseln zeigen, dass die Bedeutung von physischen Inseleigenschaften für Diversität kontinuierlich mit der Größe der betrachteten Untersuchungsfläche von der Insel- bis zur Plotebene abnimmt, wohingegen der Einfluss von lokalen Umweltbedingungen zunimmt. Lokale Artgemeinschaften sind häufig gesättigt, wodurch die Anzahl an Arten, die aus dem regionalen Artenbestand einwandern können, limitiert wird. Um Vorhersagen über lokalen Artenreichtum zu machen, ist es daher wichtig, die Skalenabhängigkeit der Effekte des regionalen Artenbestandes zu berücksichtigen. Großgruppen von Pflanzen unterscheiden sich in ihrer Ausbreitungsfähigkeit, ihrem Genfluss, Artbildungsraten und Anpassungen an das Klima. Dementsprechend zeigen die vergleichenden Analysen zwischen taxonomischen Pflanzengruppen deutliche Unterschiede in der Reaktion von Artenreichtum und phylogenetischen Diversitätsmustern auf abiotische Faktoren. Die Arten-Fläche-Beziehung, d.h. die Zunahme von Artendiversität mit zunehmender Fläche, variiert zwischen den Pflanzengruppen. Die Steigung der Arten-Fläche-Beziehung ist für Spermatophyten größer als für Pteridophyten und Bryophyten, wohingegen der y-Achsenabschnitt kleiner ist. Unter der Annahme, dass Merkmale und klimatische Anpassungen innerhalb von taxonomischen Gruppen phylogenetisch konserviert sind, führen die Filterwirkung von Ausbreitungsbarrieren und Umwelteigenschaften sowie in situ Artbildung zu Gemeinschaften eng verwandter Arten (phylogenetic clustering). Die Ergebnisse zeigen, dass physische und bioklimatische Inseleigenschaften, die mit der Filterwirkung und Artbildung in Verbindung stehen, die phylogenetische Struktur von Inselgemeinschaften beeinflussen. Die Stärke und Richtung der Zusammenhänge variieren zwischen taxonomischen Gruppen. Abiotische Faktoren erklären mehr Variation in phylogenetischer Diversität für alle Angiospermen und Palmen als für Farne, was auf Grund höherer Ausbreitungsfähigkeit und größerer Verbreitungsgebiete von Farnen den Erwartungen entspricht. Die abiotische Charakterisierung und Klassifizierung der weltweiten Inseln und die zugehörigen Daten ermöglichen eine integrativere Berücksichtigung von Inseln in der makroökologischen Forschung. In dieser Arbeit präsentiere ich die ersten Vorhersagen globaler Pflanzenartenvielfalt auf Inseln und die ersten Analysen zu unterschiedlichen Diversitätskomponenten (α, β, γ und phylogenetische Diversität) von Inselsystemen und ihren abiotischen Einflussfaktoren auf globalem Maßstab. Ich zeige, dass Zusammenhänge zwischen Umweltfaktoren und Artenzahl sowie phylogenetischen Eigenschaften von Inselgemeinschaften zwischen unterschiedlichen taxonomischen Gruppen in Abhängigkeit ihrer vorwiegenden Ausbreitungs- und Artbildungseigenschaften variieren können. Dies ist eine neue Sichtweise in der makroökologischen Inselforschung, die Rückschlüsse auf die Mechanismen hinter Diversitätsmustern von Pflanzen auf Inseln erlaubt. Ein detailliertes Verständnis davon, wie Diversität unterschiedlicher Pflanzengruppen durch Immigration und Diversifizierung auf Inseln entsteht, dürfte auch das Verständnis globaler Diversitätsmuster im Allgemeinen verbessern.

Abstract:
This chapter examines the evolution of photosynthetic organisms on land, noting that the vast majority of photosynthetic life was confined to aquatic habitats for the first three billion years of their existance. It discusses genomic novelty, stating that this was common in streptophyte algae, which developed increasingly complex multicellular forms with a wider range of tissue and organ types. It also looks at bryophytes, noting how these dominated land flora from 450 to 360 Ma, which is a relatively warm, wet period favouring the rise of pteridophytes. The chapter reviews how high photosynthetic productivity led to atmospheric O2 levels rising to over 30% and the formation of the Carboniferous coal deposits from huge amount of plant remains. It explains that 1% of all flowering plants have partially or completely lost the ability to photosynthesize and have instead become parasites.
