Abstract:
... Novel biotechnological approaches such as Metabolic Engineering (ME) and New Plant Breeding Techniques (NPBTs) are currently being developed to produce biological compounds for food and non-food products. NPBTs span a range of methods for in vivo production in crops, some of which are classified as GMOs while others aren't. Deploying such techniques will not only provide new opportunities for indu ...

Abstract:
... We examine a conservation problem in which the recovery of an endangered species depends on a captive breeding and reintroduction program. The model is applied to the case of the black-footed ferret (Mustela nigripes), an endangered species in North America reliant on captive breeding for survival. The timing of reintroduction is an important concern in these programs as there is a tradeoff betwee ...

Abstract:
... Root and foot diseases severely impede grain legume cultivation worldwide. Breeding lines with resistance against individual pathogens exist, but these resistances are often overcome by the interaction of multiple pathogens in field situations. Novel tools allow to decipher plant–microbiome interactions in unprecedented detail and provide insights into resistance mechanisms that consider both simu ...

Abstract:
... Despite the importance of roots, they have largely been ignored by modern crop research and breeding. We discuss important progress in crop root research and highlight how the context-dependent optimisation of below- and above-ground plant components provides opportunities to improve future crops in the face of increasing environmental fluctuations. ...

Abstract:
... Subordinates “pay rent” to stay in their group, but pay less when they can move elsewhere. For many animals, group living comes with costs: smaller individuals get evicted unless they help on the territory. Using theoretical models, we show that negotiation is key to enforcing pay-to-stay cooperation: subordinates provide fitness benefits to dominants and negotiate help based on breeding opportuni ...

Abstract:
... In this opinion article, we challenge the traditional view that breeding for reduced Cl− uptake would benefit plant salinity tolerance. A negative correlation between shoot Cl− concentration and plant biomass does not hold for halophytes – naturally salt tolerant species. We argue that, under physiologically relevant conditions, Cl− uptake requires plants to invest metabolic energy, and that the p ...

Abstract:
... Individual variation in resource acquisition should have consequences for life‐history traits and trade‐offs between them because such variation determines how many resources can be allocated to different life‐history functions, such as growth, survival and reproduction. Since resource acquisition can vary across an individual's life cycle, the consequences for life‐history traits and trade‐offs m ...

Abstract:
... BACKGROUND: Aedes aegypti is an efficient primary vector of dengue, and has a heterogeneous distribution in Singapore. Aedes albopictus, a poor vector of dengue, is native and ubiquitous on the island. Though dengue risk follows the dispersal of Ae. aegypti, the spatial distribution of the vector is often poorly characterized. Here, based on the ubiquitous presence of Ae. albopictus, we developed ...

Abstract:
... Globally, many bird species that rely on native woodland or forest environments are declining due to vegetation clearing for livestock pastures and cereal cropping. In many landscapes, woodland remnants are restricted to waterways and roadsides in narrow, sometimes degraded patches, and not all patches can necessarily provide the resources required to support bird populations.
