High-resolution coproecology: Using coprolites to reconstruct the habits and habitats of New Zealand’s extinct upland Moa (Megalapteryx didinus) [PDF]

, 2005
Knowledge about the diet and ecology of extinct herbivores has important implications for understanding the evolution of plant defence structures, establishing the influences of herbivory on past plant community structure and composition, and identifying

Epigenetics of Ancient DNA [PDF]

Acta Naturae, 2016
Initially, the study of DNA isolated from ancient specimens had been based on the analysis of the primary nucleotide sequence. This approach has allowed researchers to study the evolutionary changes that occur in different populations and determine the influence of the environment on genetic selection.

Old wild wolves: ancient DNA survey unveils population dynamics in Late Pleistocene and Holocene Italian remains [PDF]

PeerJ, 2019
Background The contemporary Italian wolf (Canis lupus italicus) represents a case of morphological and genetic uniqueness. Today, Italian wolves are also the only documented population to fall exclusively within the mitochondrial haplogroup 2, which was ...

Post‐Translational Modifications in Animal Circadian Clocks

Advanced Science, EarlyView.
Circadian clocks coordinate physiology with daily environmental cycles through conserved transcriptional–translational feedback loops. This review summarizes how post‐translational modifications fine‐tune clock function, highlights the evolutionary convergence of circadian timekeeping in Drosophila and mammals, and emphasizes the central of these ...

Mitochondrial Genomes from New Zealand’s Extinct Adzebills (Aves: Aptornithidae: Aptornis) Support a Sister-Taxon Relationship with the Afro-Madagascan Sarothruridae

Diversity, 2019
The recently extinct New Zealand adzebills (Aptornithidae, Aptornis spp.) were an enigmatic group of large flightless birds that have long eluded precise taxonomic assignment as they do not closely resemble any extant birds.

Exploring mobility in Italian Neolithic and Copper Age communities

Scientific Reports, 2021
As a means for investigating human mobility during late the Neolithic to the Copper Age in central and southern Italy, this study presents a novel dataset of enamel oxygen and carbon isotope values (δ18Oca and δ13Cca) from the carbonate fraction of ...

Interrogation of modern and ancient genomes reveals the complex domestic history of cattle [PDF]

, 2014
The analysis of mitochondrial and nuclear DNA sequence polymorphisms from modern cattle populations has had a profound impact on our understanding of the events surrounding the domestication of cattle.
