Integrating hydrological connectivity and zooplankton composition in Arctic ponds and lakes

open access: yesFreshwater Biology, 2023
Arctic landscapes are characterised by their numerous ponds and lakes. With increased climate warming and consequent changes in hydrological connectivity, the ecology of many of these waterbodies is expected to change.

Photodegradation of glyphosate in water and stimulation of by-products on algae growth

open access: yesEcotoxicology and Environmental Safety, 2023
Glyphosate is the most widely used herbicide in global agricultural cultivation. However, little is known about the environmental risks associated with its migration and transformation. We conducted light irradiation experiments to study the dynamics and

Algal Indices as a Biomonitoring Tool to Assess Eutrophication in the Urban Ponds: a Case Study [PDF]

open access: yesPollution, 2020
Eutrophication of the urban water bodies is one the biggest challenge causing severe ecological and economic loss. Urban ponds are more prone to eutrophication due to their small size and polluted catchment areas.

Characterisation of bacterioplankton communities in the meltwater ponds of Bratina Island, Victoria Land, Antarctica [PDF]

open access: yes, 2014
A unique collection of Antarctic aquatic environments (meltwater ponds) lies in close proximity on the rock and sediment-covered undulating surface of the McMurdo Ice Shelf, near Bratina Island (Victoria Land, Antarctica).

Factors of surface thermal variation in high-mountain lakes of the Pyrenees.

open access: yesPLoS ONE, 2021
Thermal variables are crucial drivers of biological processes in lakes and ponds. In the current context of climate change, determining which factors better constrain their variation within lake districts become of paramount importance for understanding ...

The distribution and evolution of supraglacial lakes on 79° N Glacier (north-eastern Greenland) and interannual climatic controls [PDF]

open access: yesThe Cryosphere, 2021
The Nioghalvfjerdsfjorden glacier (also known as the 79∘ North Glacier) drains approximately 8 % of the Greenland Ice Sheet. Supraglacial lakes (SGLs), or surface melt ponds, are a persistent summertime feature and are thought to drain rapidly to the ...

Flood, drought and the inter-annual variation to the number and size of ponds and small wetlands in an English lowland landscape over three years of weather extremes [PDF]

open access: yes, 2015
Ponds are biodiversity hotspots, but pond conservation is hampered by problems auditing these small, often temporary, habitats. Data on temporal changes to the number of ponds in response to weather variations are lacking.

Japanese geochemical studies on the McMurdo Sound region in Antarctica during the 1983-84 austral summer

open access: yesAntarctic Record, 1985
During the 1983-84 austral summer, Japanese geochemical studies in the Dry Valleys and Ross Island of the McMurdo Sound region in Antarctica were carried out to observe the annual variation of the vertical distribution of physicochemical properties of ...
