Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility

Advanced Intelligent Systems, EarlyView.
This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

Molecular Phylogeny, Biogeography, and Habitat Preference Evolution of Marsupials [PDF]

Molecular Biology and Evolution, 2014
Marsupials exhibit great diversity in ecology and morphology. However, compared with their sister group, the placental mammals, our understanding of many aspects of marsupial evolution remains limited. We use 101 mitochondrial genomes and data from 26 nuclear loci to reconstruct a dated phylogeny including 97% of extant genera and 58% of modern ...

Effect of locomotor preference on the evolution of mitochondrial genes in Bovidae

Scientific Reports
Locomotor preferences and habitat types may drive animal evolution. In this study, we speculated that locomotor preference and habitat type may have diverse influences on Bovidae mitochondrial genes. We used selection pressure and statistical analysis to

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

American Journal of Botany, EarlyView.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

Characteristics of Javan Coucal (Centropus nigrorufus) Preferential Habitat in Wonorejo Surabaya

Media Konservasi, 2018
Javan coucal (Centropus nigrorufus) is one of the endemic birds of Java that has limited distribution in coastal areas. This study aimed to determine the spatial distribution and habitat preference of javan coucal in Wonorejo Region, in the East Coast of

Habitat selection and indirect interactions in fish ommunities [PDF]

, 2013
To increase the understanding of freshwater lake ecosystems, I have studied the habitat selection of perch (Perca fluviatilis L.), roach (Rutilus rutilus (L.)), and vendace (Coregonus albula (L.)).
