Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

open access: yesNew Phytologist, EarlyView.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

The Changing Face of the Lithosphere‐Asthenosphere Boundary: Imaging Continental Scale Patterns in Upper Mantle Structure Across the Contiguous U.S. With Sp Converted Waves

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Juxtaposed terranes of highly varied tectonic history make up the contiguous U.S.: the tectonically active western U.S., the largely quiescent Archean and Proterozoic cratons of the central U.S., and the Phanerozoic orogen and rifted margin of the ...

Re-os isotope constraints on the age of the Lithospheric mantle beneath western Greenland. [PDF]

open access: yes, 2007
Alkaline magmatic activity across Western Greenland (W.G.) provides a record of lithosphere evolution over the last 600 Ma. Ultra Mafic Lamprophyre (UML) magmatism in particular has erupted an exceptional inventory of mantle xenoliths allowing a detailed

Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

open access: yesPhotochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Intracontinental Deformation Caused by Gravitational Lithosphere Removal [PDF]

open access: yes, 2015
Gravitational removal of the dense lower lithosphere is proposed to be a fundamental process in continental tectonics. This has been used to explain seismological observations of an abnormally thin lithosphere beneath some regions and evidence for ...

Oral health and systemic health outcomes: A call for interdisciplinary action

open access: yesPeriodontology 2000, EarlyView.
Abstract Objectives To make the case, from periodontology and dental public health, for interdisciplinary action on oral and systemic health, and to set out recommendations for practice, policy, education, and research. Materials and Methods A joint working group of the European Federation of Periodontology (EFP) and the European Association of Dental ...

Interaction of mantle convection with the lithosphere and the origin of kimberlites

open access: yesГеофизический журнал, 2013
Thermobarometry of xenolites/xenocrysts from 39 kimberlites of Eurasia, Africa, and North America demonstrates that the deepest xenolites, as well as all the other, are exhumed from the depleted lithosphere implying in agreement with petrologic and ...

Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

Upper-mantle seismic anisotropy from SKS splitting in the South American stable platform: A test of asthenospheric flow models beneath the lithosphere

open access: yes, 2011
Upper-mantle seismic anisotropy has been extensively used to infer both present and past deformation processes at lithospheric and asthenospheric depths.
