The Multidisciplinary Approach in the Study of Landscape Evolution: The Fluvial Capture of the San Donato Creek (Gubbio, Central Italy), an Example of Hydrological Regime and Hydrogeological Risk Changes

Land, 2023
Historical maps, especially those at a small scale and rich in detail (e.g., the old “Cadastres”), represent an exceptionally important tool for understanding the recent historical evolution of landscapes.

Biological evolution in a multidimensional fitness landscape [PDF]

Physical Review E, 2012
We considered a {multi-block} molecular model of biological evolution, in which fitness is a function of the mean types of alleles located at different parts (blocks) of the genome. We formulated an infinite population model with selection and mutation, and calculated the mean fitness.

Identification of the Campanian Ignimbrite in the Dead Sea and consequent time-transgressive hydroclimatic shifts in the Eastern Mediterranean

Scientific Reports
Robust chronologies and time equivalent tephra markers are essential to better understand spatial palaeoenvironmental response to past abrupt climatic changes.

SELVa: Simulator of Evolution with Landscape Variation [PDF]

PLOS ONE, 2019
Organisms evolve to increase their fitness, a process that may be described as climbing the fitness landscape. However, the fitness landscape of an individual site, i.e., the vector of fitness values corresponding to different variants at this site, can change with time due to changes in the environment or substitutions at other epistatically ...

T2* Magnetic Resonance Imaging Uncovers Hemosiderin Burden in Pediatric Hemophilia: A Call for Sensitive Imaging Biomarkers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hemophilic arthropathy remains the leading morbidity in hemophilia despite modern prophylaxis, and early joint damage may be missed by routine exams. This study explored T2* MRI as a noninvasive biomarker of hemosiderin deposition in pediatric hemophilia.

Landscape evolution and equilibrium in Southern Africa : insights from cosmogenic noble gases in Karoo dolerites and geospatial analyses [PDF]

, 2010
Includes abstract.Includes bibliographical references (p. 321-356).Southern Africa’s landscape is characterised by a high plateau (elevation > 1,000 m) bound by escarpments and extensional continental margins, and the region has been influential in the ...

Evolutionary accessibility of mutational pathways [PDF]

, 2011
Functional effects of different mutations are known to combine to the total effect in highly nontrivial ways. For the trait under evolutionary selection (‘fitness’), measured values over all possible combinations of a set of mutations yield a fitness ...

Spatial variation in landscape evolution of the Xiaojiang Region, SE Tibetan Plateau

Frontiers in Earth Science, 2023
Both tectonism and erosion are presumed to have influenced the landscape evolution of the Xiaojiang Region, SE Tibetan Plateau. However, it remains unclear which of these broad processes has played the dominant role in determining landscape form and ...

The genomic landscape of language: Insights into evolution [PDF]

Journal of Language Evolution, 2017
Abstract Studies of severe, monogenic forms of language disorders have revealed important insights into the mechanisms that underpin language development and evolution. It is clear that monogenic mutations in genes such as FOXP2 and CNTNAP2 only account for a small proportion of language disorders seen in children, and the genetic basis ...

ASSIST: Refinement of a Benefits Navigator Intervention Among Low‐Income Pediatric Oncology Families

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Children with cancer living in poverty experience worse survival and quality of life. Interventions connecting low‐income families to benefits (e.g., Supplemental Nutrition Assistance Program [SNAP] improve health outcomes; yet nearly 50% of SNAP‐eligible pediatric oncology families are unenrolled.
