Comparing the accuracy of PCR-capillary electrophoresis and cuticle microhistological analysis for assessing diet composition in ungulates: A case study with Pyrenean chamois. [PDF]

PLoS One, 2019
The study of diet composition is required to understand the interactions between animal and plant ecosystems. Different non-invasive techniques applied on faecal samples have commonly been used for such purposes, with cuticle microhistological analysis (CMA) and emerging DNA-based methods being the most relevant.

Complementarity between microhistological analysis and PCR-capillary electrophoresis in diet analysis of goats and cattle using faecal samples

Animal, 2021
An evaluation is made of the complementarity between two non-invasive techniques, cuticle microhistological analysis (CMA) and PCR-capillary electrophoresis (PCR-CE) DNA-based analysis, for the determination of herbivore diet composition from faecal samples. Cuticle microhistological analysis is based on the different microanatomical characteristics of

Assessing the diet and seed dispersal ability of non-native sambar deer (Rusa unicolor) in native ecosystems of south-eastern Australia. [PDF]

Ecol Evol, 2023
Understanding the influence of non‐native herbivores on ecosystems through dietary foraging and seed dispersal requires multiple methodologies. In south‐eastern Australia, sambar deer (Rusa unicolor) are rapidly expanding in range and placing native ecosystems at risk through browsing and as vectors for seed dispersal.

The Role of Forage Quantity and Quality in the Migration and Diet of a Northern Ungulate During Their Neonatal Period. [PDF]

Ecol Evol
In this article, we examined the differences in forage quantity and quality between two defined ranges of a wood bison population as an attempt to identify possible factors influencing their migration during the neonatal period. We found significant differences in the forage quantity and quality between ranges, suggesting a link between these factors ...

Grazing Is Associated With Dietary Diversity and Gastrointestinal Microbiota in Subterranean Rodents. [PDF]

Ecol Evol
ABSTRACT Diet significantly influences gut microbiota composition. Grazing activities alter local vegetation communities, which in turn are related to changes in the availability of food resources for wildlife. However, the relationships between grazing and the dietary diversity and gut microbiota in subterranean rodents remain poorly understood. Using

Microhistological Analysis of Sheep Gastro-Intestinal Content to Confirm Poisonous Plant Ingestion [PDF]

Journal of Range Management, 1998
The epidermal remains of 4 poisonous plant species that produce acute intoxication in ruminants were quantified by microhistological analysis in the gastro-intestinal content of sheep experimentally poisoned. These species were 'romerillo' or 'mio mio' (Baccharis coridifolia DC); 'duraznillo negro' (Cestrum parqui L'Herit.); 'poison hemlock' (Conium ...

Mock Plant Communities and a Large Mammal Case Study Reveal ITS2 Primer Bias Against Graminoids. [PDF]

Ecol Evol
DNA fecal metabarcoding has greatly advanced herbivore diet analysis, but primer selection plays an important role in mitigating PCR amplification bias, affecting ecological inferences. In this study, using plant mock communities and a large mammalian herbivore case study, we evaluated two primer pairs targeting the ITS2 region.

DNA metabarcoding analysis of the bare-nosed wombat (Vombatus ursinus) diet. [PDF]

Ecol Evol
Using metabarcoding we found bare‐nosed wombats (Vombatus ursinus) eat mostly grasses, but dietary preferences are significant across season and are habitat specific. Future studies should be investigated across the broader wombat distribution. Abstract Wombats are native herbivorous grazers that have adapted to Australia's low‐quality forage.

Density-dependent resource partitioning of temperate large herbivore populations under rewilding. [PDF]

Ecol Appl
Abstract In tropical grazer assemblies with abundant large predators, smaller herbivores have been shown to be limited by predation and food quality, while the larger species are regulated by food abundance. Much less is known about herbivore resource partitioning in temperate grazing ecosystems, where humans typically regulate large animal abundances.
