1. Fossil legume woods of the Prioria-clade (subfamily Detarioideae) from the lower Miocene (early to mid-Burdigalian) part of the Cucaracha Formation of Panama (Central America) and their systematic and palaeoecological implications

Miocene epoch; Prioria copaifera; botanical gardens; coastal forests; estuaries; fossils; legumes; microstructure; new species; niches; old and fossil wood; paleoecology; wetlands; wood anatomy; North America; Panama; South America
Abstract:
... Three fossil wood specimens are described from the Miocene (early to mid-Burdigalian) part of the Cucaracha Formation of Panama, Central America. The calcareously-permineralised fossils, which contain Teredolites borings, occur in erosive-based pebbly conglomerate lenses, interpreted as tidally-influenced fluvial channel deposits. Detailed investigation of fossil wood anatomy reveals features char ...

Abstract:
... Here we present a palaecological reconstruction covering the last 1700yr from Lydenburg fen, located in the north-eastern grassland biome, Mpumalange, South Africa. A 300cm peat sequence was analysed for biogenic (grass phytoliths, diatoms) and geochemical proxies (δ¹³C, δ¹⁵N, carbon/nitrogen content) to infer past grassland dynamics and hydro-climatic changes. The Lydenburg record reports a C4 do ...

Dendrocalamus; bamboos; biosynthesis; climate change; climatic factors; environmental indicators; growing season; leaves; paleoecology; phytoliths; plant growth; tissues
Abstract:
... Phytolith assemblages in plant leaf tissues can vary in response to seasonal climatic conditions and to their biosynthetic formation mechanisms. They therefore have potential ecological and environmental significance. Bamboo, a widely distributed plant, is an important ecological indicator because it produces some characteristic phytoliths. Assemblages of phytoliths in fresh leaves of the bamboo D ...

4. Non-pollen palynomorphs notes: 2. Holocene record of Megalohypha aqua-dulces, its relation to the fossil form genus Fusiformisporites and association with lignicolous freshwater fungi

Abstract:
... The first Holocene record of the freshwater ascomycete Megalohypha aqua-dulces from the sediment core Kongor (NE Iran) is presented here. Based on the similarity of the spore morphology with the fossil form genus Fusiformisporites, we establish a link between extant and fossil taxa. Comparative analysis of morphological characteristics of fossil spores of Fusiformisporites indicates that several d ...

Abstract:
... Development of the catchment of the St. Louis River Estuary (SLRE) since Euro-American settlement resulted in quantifiable impacts to the aquatic ecosystem. Zizania palustris L. (northern wild rice) is an important food commodity for the state of Minnesota and the SLRE contains several wild rice stands. Known threats to SLRE wild rice stands include excessive sediment and nutrient loading. This pa ...
