Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds [PDF]
Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes.

A Robotic Hand with Soft Transmission Systems for Automated Operations of Computer Mouse
Advanced Intelligent Systems, EarlyView.This article introduces a soft robotic hand designed to automate computer mouse operations. Inspired by the water vascular system, the bellows‐enclosed soft transmission system is proposed. This system can handle typical office and gaming tasks using vision and speech commands, holding the potential for applications in office scenes and gaming hardware

Local outbreaks of Operophtera brumata and Operophtera fagata cannot be explained by low vulnerability to pupal predation [PDF]
, 2013 One of the unresolved questions in studies on population dynamics of forest Lepidoptera is why some populations at times reach outbreak densities, whereas others never do.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
American Journal of Botany, EarlyView.Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Environmental vs demographic variability in stochastic predator-prey models
, 2013 In contrast to the neutral population cycles of the deterministic mean-field Lotka--Volterra rate equations, including spatial structure and stochastic noise in models for predator-prey interactions yields complex spatio-temporal structures associated ...

Ecological Effects of Fear: How Spatiotemporal Heterogeneity in Predation Risk Influences Mule Deer Access to Forage in a Sky‐Island System [PDF]
, 2019 Forage availability and predation risk interact to affect habitat use of ungulates across many biomes. Within sky‐island habitats of the Mojave Desert, increased availability of diverse forage and cover may provide ungulates with unique opportunities to ...

Mast years increase wind pollination and reduce seed predation in sugar maple (Acer saccharum)
American Journal of Botany, EarlyView.Abstract Premise In general, mast seeding (intermittent and synchronous seed production) increases plant fitness through economies of scale in which reproduction is more successful in high‐seed years. These benefits have been most studied in wind‐pollinated trees.

Causes of exotic bird establishment across oceanic islands [PDF]
, 2005 The probability that exotic species will successfully establish viable populations varies between regions, for reasons that are currently unknown. Here, we use data for exotic bird introductions to 41 oceanic islands and archipelagos around the globe to ...

Australian Journal of Social Issues, EarlyView.ABSTRACT This narrative literature review examines key issues surrounding psychosocial disability support in the National Disability Insurance Scheme (NDIS). It highlights the NDIS's neoliberal approach to support, which has underpinned a lack of clarity around the conceptualisation of psychosocial disability and recovery.
