Below‐ground drivers of rhizosphere functional gene assembly during Moso bamboo expansion

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Moso bamboo (Phyllostachys edulis) expansion threatens subtropical forest biodiversity, yet how intraspecific root trait variation shapes rhizosphere microbial functional potential remains unclear.

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Multiple scales of biological variability in New Zealand streams : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Ecology at Massey University, Manawatū, New Zealand [PDF]

, 2016
Stream fish communities in Taranaki, New Zealand, were studied for the patterns and drivers of their spatial ecology. The study was focused on three main themes: a) complementarity between geography and landuse in driving regional distribution patterns ...

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

Archaeometry, EarlyView.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Exploring motion using geometric morphometrics in microscopic aquatic invertebrates: ‘modes’ and movement patterns during feeding in a bdelloid rotifer model species

Movement Ecology
Background Movement is a defining aspect of animals, but it is rarely studied using quantitative methods in microscopic invertebrates. Bdelloid rotifers are a cosmopolitan class of aquatic invertebrates of great scientific interest because of their ...

3D - Geomorphometrics tooth shape analysis in hypodontia

Frontiers in Physiology, 2014
Assessment of tooth morphology is an important part of the diagnosis and management of hypodontia patients. Several techniques have been used to analyze tooth form in hypodontia patients and these have shown smaller tooth dimensions and anomalous tooth ...

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...
