Culturing the solitary ascidian Phallusia nigra in closed and open water systems for tropical environmental research

Limnology and Oceanography: Methods, EarlyView.
Abstract Marine and coastal ecosystems have been undergoing dramatic shifts due to global environmental changes. The rise in seawater temperature, ocean acidification, hypoxia, eutrophication, and anthropogenic pollution severely affects marine organisms.

Structural characterization of the metamorphic basement from North Dobrogean Promontory (Romania) using geophysical well logging

E3S Web of Conferences, 2018
Metamorphic processes, leading to mineralogical and structural changes of the rocks in response to physical (pressure, temperature) and chemical conditions, can be associated with the development of sinmetamorphic or post-metamorphic fractures.

A black shale protolith for gold-tellurium mineralisation in the Dalradian Supergroup (Neoproterozoic) of Britain and Ireland [PDF]

, 2017
The Dalradian Supergroup of Britain and Ireland is mineralised by gold-tellurium vein deposits. The host succession includes carbonaceous, pyritic shales (pelites) which were a source of trace elements, including gold and tellurium.

Relaxation of the leaf economics spectrum within and across quaking aspen Populus tremuloides genotypes

Oikos, EarlyView.
Plant functional traits typically show strong covariation, e.g. as in the worldwide leaf economics spectrum (LES). Covariation is thought to arise from selective forces and physical constraints. However, processes shaping covariation at interspecific scales may differ from those at intraspecific scales.

The women honoured in flowering plant genera: From myth to reality

PLANTS, PEOPLE, PLANET, EarlyView.
Many flowering plant genera are named for people, but there is a gender gap in this naming, with only 6% of eponyms honouring women. Here we explore this gap by examining in detail women for whom plant genera are named. Our open shared dataset serves to make women honoured in plant genera more discoverable, resulting in further impact by allowing ...

Determination of Thermal Damage and Failure Time Analysis in Rocks Using Stochastic Models

Quality and Reliability Engineering International, EarlyView.
ABSTRACT This study presents a stochastic modeling framework for estimating thermal damage and predicting failure time in fine‐grained Dholpur sandstone subjected to high‐temperature conditions. Unlike conventional approaches that rely on extensive thermally altered physical and mechanical properties, the proposed method utilizes only temperature and ...

Tributary‐Trunk Sedimentary Links in an Inter‐Dam River Reach: Lessons From Low‐Altitude High‐Gradient Forested Streams, the Dyje River (Czechia‐Austria)

River Research and Applications, EarlyView.
ABSTRACT This study employs two measures of connectivity, valley confinement index (VCI) and effective catchment area (ECA), combined with a field survey of active sediment sources (ASS) to unravel the tributary‐trunk sedimentary links in the 42.5 km long inter‐dam reach of the Dyje River, Czech‐Austrian border.

Freeze‐tolerant frogs accumulate cryoprotectants using photoperiod: A potential ecological trap

Journal of Animal Ecology, EarlyView.
Climate change is disrupting the reliability of photoperiod as a cue signalling seasonal changes in temperature. We show that gray treefrogs under a late‐season photoperiod accumulated large reserves of ‘antifreeze’ and exhibited greater cold tolerance.
