A Multi Hidden Recurrent Neural Network with a Modified Grey Wolf Optimizer

, 2019
Identifying university students' weaknesses results in better learning and can function as an early warning system to enable students to improve. However, the satisfaction level of existing systems is not promising.

Effect of population reinforcement method, site, and plant characteristics on early establishment of the rare endemic plant species Minuartia smejkalii

Nordic Journal of Botany, EarlyView.
Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.

Can restoring wolves aid in lynx recovery?

Wildlife Society Bulletin, 2011
Herein, we examine the hypothesis that relatively low densities of snowshoe hares (Lepus americanus) and the imperiled status of lynx (Lynx canadensis) may be partially due to an ecological cascade caused by the extirpation of gray wolves (Canis lupus ...

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

Oikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Individual variation in perceived density of conspecifics and its impacts on the realization of ecological niches

Oikos, EarlyView.
Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

Oikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

People and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.
