Ecomorphological and Ecometric Approaches to Clarifying Homo sapiens Palaeoecology
… implications for our interpretation of hominin palaeoecology and biogeography during the LEP, MP, and ELP periods. While both ecomorphology and ecometrics are validated as valuable and informative palaeoecological methods, some limitations are identified, and methodological refinements are …

Palaeoecology and vegetation dynamics in the Cederberg wilderness area
The Cederberg Wilderness Area, in the Cape Floristic Region, South Africa, contains over 2000 plant species, 280 of which are endemic. The area has been subject to various forms of land use for millennia ranging from hunter-gatherers, herders, and farmers to visitors today. This study used …

Palaeoecology of the late Permian mass extinction and subsequent recovery
Climate warming during the latest Permian is associated with the most severe mass extinction event of the Phanerozoic, and the expansion of hypoxic and anoxic conditions into shallow shelf settings. Our understanding of the magnitude, pattern and duration of the extinction event and subsequent …

The sedimentology, palaeoecology and stratigraphy of cretaceous rocks in N.W. Scotland
Sediments of Cretaceous age in N.W. Scotland outcrop in small, often isolated exposures throughout the Inner Hebrides and Morvern, and have been dealt with cursorily in most previous work on the Cretaceous rocks of Britain. The aims of this study were (i)to propose a formal integrated stratigraphic …

The sedimentology and palaeoecology of the Coralline Crag (Pliocene) of Suffolk
The Coralline Crag is a Pliocene, shallow marine, bioclastic sand formation with an outcrop restricted to south-east Suffolk. Four distinct sedimentary facies have been recognised which indicate that the Coralline Crag was deposited during a single marine transgression. The stratigraphically lowest …

Pseudoproxy modelling to explore ecosystem dynamics and assess uncertainties in palaeoecology
… how they will respond to such novel pressures. Palaeoecology offers crucial understanding of how ecosystems have responded to environmental change in the past, and provides valuable insight into how ecosystems will change in the future. However, palaeo-proxy records are associated with many …

Multi-isotope analysis and the reconstruction of prey species palaeomigrations and palaeoecology
… reindeer, allowing greater insight into the palaeoecology of this prey animal, and the palaeoenvironment in which Neanderthals lived and hunted.

Palaeoecology and population demographics of the extinct New Zealand moa (Aves: Dinornithiformes).
… this period. A new opportunity to examine moa palaeoecology has been presented by the discovery of moa coprolites. Previous reconstructions of moa diet have concluded that moa were predominantly browsers of trees and shrubs. There is considerable debate over the role of moa in the evolution of …

Unravelling the impacts of palaeoecology, palaeoenvironment and lithofacies on sedimentary organic NSO compounds
The organic matter in sedimentary rocks that is soluble in common organic solvents comprises a complex mixture of hydrocarbons and NSO compounds (nitrogen, sulfur and oxygen bearing). The N, S, O atoms can be derived from both biogenic sources and abiogenic processes, thus organic NSO compounds are …

Foraminiferal biostratigraphy and palaeoecology of the Albian to Santonian (Cretaceous) of Bornholm, Denmark
… is proposed for the study interval combining palaeoecology, biostratigraphy, lithostratigraphy and basin events. Transgressive phases are recognised in the Early Albian, Early Cenomanian and Late Cenomanian-Early Turonian. The Coniacian interval overall shows stable outer shelf water depths, …

The biostratigraphy, palaeoecology and geochemistry of a long lacustrine sequence from NW Greece
Examination of an important new 319m core of lake sediment recovered from Ioannina in NW Greece has attempted to relate changes in the lake to variations in the regional climate of south-central Europe over the last 600,000 years. The site is known to have been extremely sensitive to past climatic …

PALAEOECOLOGY, PALAEOENVIRONMENTAL ANALYSIS AND THEIR APPLICATION TO SEQUENCE STRATIGRAPHY: LOWER CRETACEOUS, LUSITANIAN BASIN, PORTUGAL
… many recent studies have attempted to combine palaeoecology and sequence stratigraphy, the sequence stratigraphic model is commonly used to provide a temporally constrained framework for the evaluation of ecological and evolutionary events. This study shows how palaeoecology can be used as a …

Taphonomy and Palaeoecology of multi-element skeleton invertebrates: a genetic model for exceptional preservation
The aim of the research is to improve the understanding on the origin of fossil accumulations by investigating their taphonomic and sedimentological features and by using stratigraphic data and the autecology of the organisms forming the shell beds. A number of highly different oligospecific high …

Late quaternary palaeoecology of the central and marginal uplands of the Karoo, South Africa
Pollen analysis of organic sediments from vleis in upland areas of the Central and marginal Karoo has provided a vegetation history spanning the late Quaternary in the Winterberg, Sneeuberg, Nuweveldberg and Cederberg Mountains. Fossil pollen studies indicate moist conditions at the beginning of …

Quantifying variation in teeth of Late Triassic vertebrates: implications for identification, palaeoecology, and biostratigraphy
The Triassic Period (~252–201.5 Ma) represents one of the most dynamic intervals in Earth's history, characterised by major evolutionary radiations following the end-Permian mass extinction, the emergence and diversification of key vertebrate lineages, and the establishment of modern terrestrial …

Late glacial and Holocene marine geology, palaeoceanography and palaeoecology of the Northern Isles of Scotland
… Holocene marine geology, palaeoceanography and palaeoecology of the northwestern North Sea. Chapters 2 and 4 investigate the sedimentary expression of the Storegga tsunami event (ca. 8,150 cal a BP), and the implications for the semi-coeval 8.2 ka cooling event. Within the Holocene mud sequences …
