The ecology of insect pests and fungal pathogens of drought stressed eucalypt plantations in southern Queensland

open access: yes, 2012
The eucalypt plantation industry is rapidly expanding to supply an increasing demand for wood both in Australia and other parts of the world. Despite rapid industry development, most eucalypt plantations are restricted to four coastal areas.

Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

Insect herbivore communities colonising the flower-heads of Berkheya in South Africa and Carduoideae in Europe and California

open access: yes, 1989
Bibliography: leaves 231-233.One of the main purposes of this study was to determine whether general conclusions can be made about the association of insect herbivores with Berkheya and thistles and whether there are any 'rules' that have influenced the ...

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Effector Pt9226 from Puccinia triticina Presents a Virulence Role in Wheat Line TcLr15

open access: yesMicroorganisms
Effectors are considered to be virulence factors secreted by pathogens, which play an important role during host-pathogen interactions. In this study, the candidate effector Pt9226 was cloned from genomic DNA of Puccinia triticina (Pt) pathotype THTT ...

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Greater future range expansions in alien than native ant species

open access: yesOikos, EarlyView.
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.

Ecdysone receptor strongly influences larval–pupal–adult transition and melanization in Tuta absoluta

open access: yesCABI Agriculture and Bioscience
Background Tomato leaf miner (Tuta absoluta) is a quarantined pest that damages Solanaceae crops worldwide. The overuse of traditional pesticides negatively affects both human health and the environment.

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

open access: yesPeople and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.

Effects of new forest management on insect damage risk in a changing climate

open access: yes, 2015
Recent findings suggest that damage by forest insect pests will increase as a consequence of climate warming. Here, we ask whether changes in forest management can alter and possibly mitigate the increased risk of damage and outbreaks. We focus mainly on
