A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

open access: yesBoreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Responses of Rotifer Community to Microhabitat Changes Caused by Summer-Concentrated Rainfall in a Shallow Reservoir, South Korea

open access: yesDiversity, 2020
Empirical studies suggest that the structural heterogeneity of aquatic ecosystem microhabitat is determined by the diversity and abundance of macrophytes.

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

open access: yesEcological Entomology, EarlyView.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Habitat architecture influencing microcrustaceans composition: a case study on freshwater Cladocera (Crustacea Branchiopoda)

open access: yesBrazilian Journal of Biology
Environmental complexity is considered a key factor for diversity enhancement in aquatic ecosystems. Macrophyte stands are a major contributor for this complexity due to their differential architectures.

Environmental assessment and macrophytes of the watercourses Bloščica and Cerkniščica

open access: yesActa Biologica Slovenica, 2010
The aim of the present work was to determine the abundance and distribution of macrophytes in streams Bloščica and Cerkniščica and to establish the relation between environment characteristics and abundance of macrophytes.

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider

open access: yesEcological Entomology, EarlyView.
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

The Role of Emergent Aquatic Macrophytes in Changing Water Quality at Al-Shafi Marsh, Southern Iraq

open access: yesمجلة مركز بحوث التقنيات الاحيائية, 2009
This study was done at Al-Shafi marsh, southern Iraq, to determine the role of emergent aquatic macrophytes in changing the water quality. Three dominant emergent aquatic macrophytes were identified in the marsh and the vegetation cover percentages for ...
