Abstract A solver for the nonhydrostatic deep-atmosphere equations of motion is described that extends capabilities Model Prediction Across Scales-Atmosphere (MPAS-A) beyond existing shallow-atmosphere solver. The discretization and additional terms within this extension maintain C-grid staggering, hybrid height vertical coordinate, spherical centroidal Voronoi mesh used by MPAS, also preserve ...

Marine Protected Areas (MPAs) in South Africa have a long history with currently 5% of the mainland’s ocean territory protected. The MPAs are celebrated and appreciated for their representative coverage several habitat types ecological benefits. However, story correlational coastal community exclusion is not one that often told ‘success’ African MPAs. In this review we describe marine conservat...

The general aim of this paper is to present a possible multidisciplinary approach to the problem of connectivity among marine protected areas (MPAs) describing some of the mechanisms and vectors that control the dispersal of propagules among spatially distributed marine communities of MPAs in the Southern Adriatic Sea. A joint approach is described that focuses on (a) measurements of surface wa...

CXCR4 is the receptor of CXC chemokine SDF-1 and may play a role in the homing of hematopoietic stem cells. We have investigated the CXCR4 gene expression during ATRA treatment in acute promyelocytic leukaemia (APL) patients. APL is a characteristic disorder with a specific translocation between PML and RAR alpha genes on chromosome 15 and 17. ATRA-induced differentiation of APL cells is strict...

Administrators at 68% of 4-year colleges nationwide (N = 747) responded to a survey concerning the types of programs and policies they used in response to students’ heavy drinking. Most schools conducted targeted alcohol education and invested in institutional prevention efforts; half conducted social norms campaigns; a sizeable minority restricted alcohol on campus. Schools that focused on dem...

Marine Protected Areas (MPAs) are an important tool for management and conservation play increasingly recognised role in societal human well-being. However, the assessment of MPAs often lacks a simultaneous consideration ecological socio-economic outcomes, this can lead to misconceptions on effectiveness MPAs. In perspective, we present transdisciplinary approach based Delphi method mapping eva...

The use of marine protected area (MPA) networks to sustain fisheries and conserve biodiversity is predicated on two critical yet rarely tested assumptions. Individual MPAs must produce sufficient larvae that settle within that reserve's boundaries to maintain local populations while simultaneously supplying larvae to other MPA nodes in the network that might otherwise suffer local extinction. H...

Genetic diversity is needed for species' adaptation to changing selective pressures and is particularly important in regions with rapid environmental change such as the Baltic Sea. Conservation measures should consider maintaining large gene pools to maximize species' adaptive potential for long-term survival. In this study, we explored concerns regarding genetic variation in international and ...

Designation as Marine Protected Areas (MPAs) can protect coastal ecosystems, but apparently has not effectively protected the rocky intertidal zone in urban Southern California. Here, illegal collecting and habitat disturbance harm coastal marine life. We surveyed day visitors to sandy beaches or adjacent rocky habitats in Orange County. Using the close-ended, double-bounded contingent valuatio...
