Host Evaluation: Reliance on Symbionts: A new metric for quantifying nutrient exchange in nutritional mutualisms

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Mutualisms between autotrophs and heterotrophs that exchange nutrients are of pivotal importance in the ecology and evolution of life on Earth. However, investigation of holobiont trophic strategy (reliance on autotrophy vs. heterotrophy) is hampered by practical challenges in quantifying their diverse nutritional pathways.

Population dynamics of stubby root nematodes (Trichodorus and Paratrichodorus spp.) associated with ‘Docking disorder’ of sugar beet (Beta vulgaris L.), in field rotations with cover crops in East England

open access: yesAnnals of Applied Biology, EarlyView.
This study evaluated the population dynamics of stubby root nematodes (SRN) in field rotations with cover crops and the subsequent effect of this rotation on sugar beet quality and quantity attributes. It was clear that the SRN densities under field conditions are influenced by multiple factors, such as the type of cover crops grown, soil disturbance ...

Biotic and abiotic modulation of drought effects on aphids and plants

open access: yesAnnals of Applied Biology, EarlyView.
Drought affects aphids, plants and their relationships (solid arrows). This study provides a quantitative synthesis of how biotic and abiotic factors modulate the effect of drought on aphids and plants at molecular to community scales (dashed arrows). Out of 329 pair‐wise relationships (drought‐biotic and drought‐abiotic) retrieved from the literature,

CRISPR vs. nematodes: A new era of genetic solutions for potato crop protection

open access: yesAnnals of Applied Biology, EarlyView.
This review highlights the impact of nematodes on potato production and explores CRISPR/Cas genome editing as a breakthrough strategy for enhancing resistance. We discuss the potential, challenges, and future directions of CRISPR‐based approaches in developing resilient potato cultivars.

Mutualism, Parasitism, and Evolutionary Adaptation

open access: yes, 2000
Our investigations concern the role of symbiosis as an enabling mechanism in evolutionary adaptation. Previous work has illustrated how the formation of mutualist groups can guide genetic variation so as to enable the evolution of ultimately independent ...

Causes of mortality in koalas autopsied at the University of Melbourne

open access: yesAustralian Veterinary Journal, EarlyView.
Objective To determine the causes of mortality in koalas autopsied at the University of Melbourne based on the retrospective analysis of autopsy reports. Methods The autopsy reports of 239 koalas examined at the University of Melbourne from 1970 to 2023 were reviewed to determine which of the comorbidities present was the primary cause to which death ...
