A phosphoprotein gene RT-qPCR assay for detecting all lineages of peste des petits ruminants virus

open access: yesFrontiers in Microbiology
Peste des petits ruminants (PPR) is a highly contagious disease caused by peste des petits ruminants virus (PPRV). PPRV is classified into four lineages based on the nucleocapsid (N) or fusion (F) genes.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Quercetin ameliorates aflatoxin B1-induced non-canonical ferroptosis in ovine oocytes through the OPA1/ACSL4 pathway

open access: yesJournal of Animal Science and Biotechnology
Background Aflatoxin B1 (AFB1), a potent mycotoxin, commonly contaminates feeds like maize and soybean, jeopardizing animal reproduction. Although AFB1 exposure is known to cause oxidative stress, immune activation, and cell death in oocytes and early ...

Infochemical use in Brassica-insect interactions : a phenotypic manipulation approach to induced plant defences [PDF]

open access: yes, 2008
Plants have developed a range of strategies to defend themselves against herbivore attack. Defences can be constitutive, i.e. always present independent of attack, or induced, i.e. only elicited when the plant is under attack.

Community-wide impacts of herbivore-induced plant responses in milkweed (Asclepias syriaca) [PDF]

open access: yes, 2004
The effects of early?season herbivory and subsequent induced plant responses have the potential to affect the diversity of herbivorous insect communities.

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Larval parasitism of the autumnal moth reduces feeding intensity on the mountain birch [PDF]

open access: yes, 2013
Plants respond to grazing by herbivorous insects by emitting a range of volatile organic compounds, which attract parasitoids to their insect hosts. However, a positive outcome for the host plant is a necessary precondition for making the attraction ...

Tri-trophic effects of inter- and intra-population variation in defence chemistry of wild cabbage (Brassica oleracea) [PDF]

open access: yes, 2010
The effect of direct chemical defences in plants on the performance of insect herbivores and their natural enemies has received increasing attention over the past 10 years.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the
