Dragonfly functional connectivity responses are dynamic relative to drought
Insect Conservation and Diversity, EarlyView.During drought, dragonfly species richness decreases. Yet, dragonfly assemblages show a higher propensity for dispersal during drought. Dispersal pathways vary among the wet and dry periods, and relative to temporal changes in the landscape. While some dragonfly species can traverse plantation compartments, conservation corridors facilitate functional ...

Seismic behavior of the contents of seismically isolated buildings
, 2021 Sismik izolasyon, gelişmekte olan depreme dayanıklı bir tasarım teknolojisidir. Özellikle ankastre binalara kıyasla kat ivmelerini azaltır. Böylece, binaların içeriğini korumada çok başarılıdır. Önceki çalışmalarda, içerik korumanın kapsamı yalnızca kat ivmelerinin incelenmesi ile yapılmıştır.

ON THE BEHAVIOUR OF BUILDINGS WITH CURVED SURFACE SLIDERS: CONSIDERATIONS AND PRELIMINARY ANALYSES
, 2015 As well-known seismic isolation is based on the terrific reduction of the seismic actions, which affect the structure, instead of relying on its strength.

Journal of Petroleum Geology, EarlyView.ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA
Meteoritics &Planetary Science, EarlyView.Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Restoration Ecology, EarlyView.Abstract Introduction Seismic lines represent one of the most extensive and persistent anthropogenic disturbances in boreal peatlands, limiting forest regeneration and altering key ecosystem functions. Inverted mounding is increasingly applied to elevate planting microsites above shallow water tables, yet evidence on short‐ to medium‐term biophysical ...
