Diversity of benthic macrofauna and physical parameters of sediments in natural mangroves and in afforested mangroves three decades after compensatory planting
(
Springer
, 2018 , Article)
Mangroves in the Arabian Gulf are under pressure from land use change, leading to compensatory planting at sites without
natural mangroves. In this study, we examine the potential long-term success of this form of ...
Food web structure of three Mediterranean stream reaches along a gradient of anthropogenic impact
(
Springer
, 2020 , Article)
Anthropogenic impact can alter food web structure through changes in species interactions. In this study, we explored the food web of three Mediterranean stream reaches (two seasonal and one permanent) along an anthropogenic ...

© 2020 Elsevier B.V. A novel approach of combining manipulative field experiments and cytogenetic endpoints was used to assess the genotoxic impact of chemical contamination on a local model bivalve species, the pearl ...
Anthropogenic related variations in the epibiotic biodiversity and age structure of the “Pearl Oyster” Pinctada radiata within the eulittoral zone of Qatar
(
Elsevier
, 2016 , Article)
Abstract Oyster aggregations provide critical habitat that contain diverse communities, with epibiota and oysters sensitive to environmental disturbance. The monitoring of oysters and associated organisms has become an ...
