Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Research Direction and Science Evaluation: The Role of Coherence and Alignment

open access: yesJournal of Economics &Management Strategy, EarlyView.
ABSTRACT The decisions of funding agencies greatly influence the direction of scientific research; however, our understanding of how applicants' research directions affect the selection process remains limited. In this study, we investigate how a project's coherence with a scientist's previous work and its alignment with current scientific trends ...

Response to Pieter C. Emmer’s ‘Reconsideration’

open access: yesNWIG, 1995
[First paragraph] Criticisms, however strongly expressed, are valuable where they extend and deepen debates. Pieter Emmer's critique, though, is so ill focused, ill informed, and intemperate, that it is difficult to know how to respond profitably ...

Two-step Gravity Inversion Reveals Variable Architecture of African Cratons

open access: yesFrontiers in Earth Science, 2021
The lithospheric build-up of the African continent is still to a large extent unexplored. In this contribution, we present a new Moho depth model to discuss the architecture of the three main African cratonic units, which are: West African Craton, Congo ...

Speculations on the formation of cratons and cratonic basins

open access: yesEarth and Planetary Science Letters, 2016
Surface wave tomography using Rayleigh waves has shown that Tibet and the surrounding mountain ranges that are now being shortened are underlain by thick lithosphere, of simi-\ud lar thickness to that beneath cratons. Both their elevation and lithospheric thickness can result from pure shear shortening of normal thickness continental lithosphere by ...

Eclogite Varieties and Their Positions in the Cratonic Mantle Lithosphere beneath Siberian Craton and Archean Cratons Worldwide

open access: yesMinerals, 2022
The pressure-temperature (PT) conditions and position of different groups of eclogites in the sub-cratonic lithospheric mantle (SCLM) worldwide were established using clinopyroxene Jd-Di and garnet thermobarometry. Beneath Siberia, Fe-eclogites found within the 3.0–4.0 GPa formed in Early Archean times.

Opportunities for targeted, small‐scale law reform in marine and coastal restoration

open access: yesRestoration Ecology, EarlyView.
Across the globe, law reform is being considered as a mechanism to support, guide, and encourage the upscaling of ecological restoration. While high‐profile examples like the European Nature Restoration Law show the value of large‐scale law reform, this scale of law reform will not be feasible or politically tractable everywhere.

THE “CLINOPYROXENE” PALEOGEOTHERM BENEATH THE OBNAZHENNAYA KIMBERLITE PIPE AND THIСKNESS OF LITHOSPHERE UNDER THE KUOYKA FIELD (SIBERIAN CRATON, YAKUTIA)

open access: yesГеодинамика и тектонофизика, 2022
The mantle paleogeotherm under the Obnazhennaya kimberlite pipe (Kuoika field, Siberian craton) was reconstructed using the chemical composition of clinopyroxene xenocrystals and the FITPLOT program.
