Palaeoenvironmental evolution and decline of the harbours of the Roman and Early Byzantine city of Elaiussa Sebaste (southeastern Turkey): natural and anthropic causes

Journal of Quaternary Science, Volume 40, Issue 1, Page 153-173, January 2025.
ABSTRACT The ancient city of Elaiussa Sebaste, currently Ayaş, is located on the southeastern coast of Turkey. It was one of the main trading Mediterranean harbours from the Augustan period until the early Byzantine era. The Arab invasion in the 7th century ce marked its definitive abandonment.

Biometry of stomata in Blechnum species (Blechnaceae) with some taxonomic and ecological implications for the ferns

Revista de Biología Tropical, 2011
Morphological stomatal traits, such as size, form and frequency, have been subject of much literature, including their relationships with environmental factors. However, little effort have focused on ferns, and very few in the genus Blechnum.

Protozoans as indicators of sequential batch processes for phenol treatment; an autoecological approach

Ecotoxicology and Environmental Safety, 2013
The objective of this study was the investigation of the potential use of protistan species as quality indicators of the activated sludge performance in sequential batch processes receiving toxic compounds. Two laboratory scale sequential batch reactors (SBR) were used, a conventional one and a system with plastic biofilm carriers (SBBR), treating ...

Sedimentary ancient DNA and HBI biomarkers as sea‐ice indicators: A complementary approach in Antarctic fjord environments

Limnology and Oceanography Letters, Volume 9, Issue 6, Page 785-795, December 2024.
Abstract Reliable high‐resolution, pre‐observational‐period sea‐ice datasets are rare but critical for contextualizing recent sea‐ice declines and future scenarios. We combine sedimentary ancient DNA of the sea‐ice dinoflagellate Polarella glacialis (Pgla‐sedaDNA) with selected highly branched isoprenoid (HBI) biomarkers alongside other indicators to ...

Woody plant communities of isolated Afromontane cloud forests in Taita Hills, Kenya [PDF]

, 2010
In the Taita Hills in southern Kenya, remnants of the original Afromontane forest vegetation are restricted to isolated mountain peaks. To assess the level of degradation and the need for forest restoration, we examined how forest plant communities and ...

Nutrient content in tissues of Groenlandia densa, Myriophyllum spicatum and Zannichellia palustris: an attempt to understand the intercompartmental relationships in a small stream in the Middle Atlas Mountains of Morocco

Oceanological and Hydrobiological Studies
Research has long focused on the relative importance of leaves and roots as sources of nutrient supply for macrophytes, as well as the function each stream compartment plays in their growth and development. This study aims to expand the debate on aquatic

Prey specificity of predatory venoms

Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.
