Multi-isotope analysis and the reconstruction of prey species palaeomigrations and palaeoecology [PDF]

open access: yes, 2010
This thesis explores the use of multi-element isotope analysis and intra-tooth sampling to reconstruct prey species ecology and biogeography. Modern caribou (Rangifer tarandus ssp.) and bison (Bison bison) from North America are used to assess the ...

From open landscapes to forest refugia: Human encroachment and climate change as drivers of red deer (Cervus elaphus) niche shifts over 21,000 years

open access: yesQuaternary Environments and Humans
The red deer (Cervus elaphus) is one of the few remnant species of the European Pleistocene megafauna. It occupies a wide range of habitats across the Holarctic, yet the factors shaping the species’ realized ecological niche over time remain poorly ...

A New foodweb based on microbes in calcitic caves: The Cansiliella (Beetles) case in Northern Italy [PDF]

open access: yesInternational Journal of Speleology, 2011
The troglobitic beetle, Cansiliella servadeii (Leptodirini), has specialized mouthparts modified for browsing and feeding under percolating water on moonmilk, a speleothem formation in Grotta della Foos, Italy. Results from analyses of stable isotopes of

Zinc Isotope Ratios as Indicators of Diet and Trophic Level in Arctic Marine Mammals.

open access: yesPLoS ONE, 2016
Carbon and nitrogen stable isotope ratios of bone collagen are an established method for dietary reconstruction, but this method is limited by the protein preservation.

Aspects of the ecology, behaviour and ecosystem effects of the marine polychaete Nereis diversicolor (O.F. Müller, 1776) in the estuaries of south-east England. [PDF]

open access: yes, 2010
PhDThe marine infaunal polychaete Nereis diversicolor has been shown to restrict the development of pioneer saltmarsh vegetation in south-east England through bioturbation and herbivory while surface deposit feeding. This can have severe implications for

Use of Stable Isotopes and GIS Modeling to Study Late Pleistocene to Holocene Environmental Change in the Waipaoa Sedimentary System, New Zealand [PDF]

open access: yes, 2009
The source to sink investigation of complex sedimentary systems necessitates chemical (stable isotope and elemental) and physical (modeling) analyses to elucidate temporal changes in volume and provenance of sediment supply.
