Seasonal variation in wild pig (Sus scrofa) diet revealed by DNA metabarcoding

open access: yesWildlife Society Bulletin, EarlyView.
Using DNA metabarcoding of fecal samples, we investigated the diet of wild pigs at an extensive bottomland hardwood forest ecosystem within Felsenthal National Wildlife Refuge in Southern Arkansas. We found that wild pig diet was highly diverse and included at least 74 plant families and 106 genera and 23 species of vertebrates.

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

open access: yesInsect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Sequencing of historical plastid genomes reveal exceptional genetic diversity in early domesticated rye plants

open access: yesiScience
Summary: In medieval central Europe, rye was one of the most important agricultural crops. We combined archaeobotanical methods and ancient DNA sequencing of historical rye material to study patterns of genetic diversity across four centuries. We applied

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

open access: yesIntegrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Long‐read sequencing for biodiversity analyses—A comprehensive guide

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract DNA‐based monitoring of biodiversity has revolutionised our ability to describe communities and rapidly assess anthropogenic impacts on biodiversity. Currently established molecular methods for biomonitoring rely heavily on classic metabarcoding utilising short reads, mostly through Illumina data.

Characterisation of a chlororespiratory pathway in Beta vulgaris and Trifolium repens : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University, New Zealand [PDF]

open access: yes, 2002
The chloroplast respiratory pathway (chlororespiration) is postulated to interact with the photosynthetic pathway through the plastoquinone (PQ) pool. Two enzymes are proposed to operate in the pathway: an NAD(P)H dehydrogenase that is homologous to the ...

Changes in the microbiome and metabolome in captive red kangaroos (Osphranter rufus) affected by macropod progressive periodontal disease

open access: yesAustralian Veterinary Journal, EarlyView.
Macropod progressive periodontal disease (MPPD) is a severe oral condition frequently observed in captive macropods, particularly red kangaroos (Osphranter rufus), yet its underlying biological features remain poorly understood. In this exploratory descriptive study, we investigated oral and fecal microbiomes and metabolomic profiles in captive red ...

A molecular phylogenetic study of Deschampsia (Poaceae: Aveneae) inferred from nuclear ITS and plastid trnL sequence data: support for the recognition of Avenella and Vahlodea [PDF]

open access: yes, 2007
The circumscription and phylogeny of Deschampsia were studied for the first time by parsimony analysis of nuclear ribosomal internal transcribed spacer (ITS) and plastid trnL intron sequences.
