Widespread changes in the relative abundances of Cyclotella sensu lato taxa have occurred in lakes of the Northern Hemisphere over the last ∼150 years, with these changes often attributed to climate-driven physical changes in lakes. While the links between Cyclotella ecology and lake thermal structure have been investigated extensively now, the role of the timing of ice-off in driving these diatom patterns remains unclear. We compared the seasonal distribution patterns of Cyclotella taxa in a… 

Evidence for temporally coherent increases in the abundance of small Discostella (Bacillariophyceae) species over the past 200 years among boreal lakes from the Experimental Lakes Area (Canada)

Increased relative abundances and accumulation rates of the small, centric diatom Discostella have been recorded in numerous paleolimnological investigations of north temperate lakes that span the

Interannual variation in seasonal diatom sedimentation reveals the importance of late winter processes and their timing for sediment signal formation

Disentangling the process information contained in a diatom sediment signature is crucial for reliable future predictions based on paleolimnological records. In this study, we combine limnological

Effects of climate change and industrialization on Lake Bolshoe Toko, eastern Siberia

Industrialization in the Northern Hemisphere has led to warming and pollution of natural ecosystems. We used paleolimnological methods to explore whether recent climate change and/or pollution had

Landscape–lake interactions in the Beartooth Mountains, Wyoming: a 350-year fire history reconstruction

Wildfire is the dominant natural disturbance agent in forests of the Greater Yellowstone Ecosystem, and can have long-lasting impacts on local landscapes and limnologic processes. We applied a

High-Throughput Sequencing of Diatom Community, Its Spatial and Temporal Variation and Interrelationships with Physicochemical Factors in Danjiangkou Reservoir, China

Diatoms constitute an important part of the phytoplankton community in lakes and reservoirs and play a significant role in regulating ecological balance. Danjiangkou Reservoir is the water source

A paleolimnological approach for interpreting aquatic effects monitoring at the Diavik Diamond Mine (Lac de Gras, Northwest Territories, Canada)

Abstract Korosi JB, Thienpont JR, Eickmeyer DC, Kimpe LE, Blais JM. 2020. A paleolimnological approach for interpreting aquatic effects monitoring at the Diavik Diamond Mine (Lac de Gras, Northwest

Neidium vietnamensis – a new diatom species (Bacillariophyceae: Neidiaceae) from Vietnam and a checklist of the genus from Southeast Asia

A new species, Neidium vietnamensis sp. nov., is described from Phu Quoc Island, South Vietnam, Southeast Asia. The valves of this new species have a distinct linear outline with non-protracted, we...



Seasonal and decadal patterns in Discostella (Bacillariophyceae) species from bi‐weekly records of two boreal lakes (Experimental Lakes Area, Ontario, Canada)

The spring dominance of Discostella in the study lakes occurred at a time of the year when nutrient concentrations were at their highest seasonally, suggesting that these taxa are neither limited directly by nutrients, nor responding to enhanced stratification during the summer months in these lakes.

Hemispheric-scale patterns of climate-related shifts in planktonic diatoms from North American and European lakes

A synthesis of over 200 diatom‐based paleolimnological records from nonacidified/nonenriched lakes reveals remarkably similar taxon‐specific shifts across the Northern Hemisphere since the 19th

Local climatic drivers of changes in phenology at a boreal-temperate ecotone in eastern North America

Ecosystems in biogeographical transition zones, or ecotones, tend to be highly sensitive to climate and can provide early indications of future change. To evaluate recent climatic changes and their

Climate‐driven changes in spring plankton dynamics and the sensitivity of shallow polymictic lakes to the North Atlantic Oscillation

The results suggest that assessments of potential impacts of climate warming on biological processes in freshwater ecosystems demand basic knowledge about the relationships between global climate indices, local meteorological conditions, and the thermal response of various lake types.

Seasonal Diatom Variability and Paleolimnological Inferences – A Case Study

The seasonality of physical, chemical, and biological water variables is a major characteristic of temperate, dimictic lakes. Yet, few investigations have considered the potential information that is

Tighter integration of the autecology of this important group of diatoms with environmental change and subsequent alterations in limnological processes will improve interpretations of palaeolimnological records, and clarify the drivers of seemingly disparate patterns in fossil records showing widespread and rapid changes across the northern hemisphere.

Evaluating planktonic diatom response to climate change across three lakes with differing morphometry

We applied a diatom-based thermal stratification index to sediment cores from three lakes in the northeast USA to evaluate the influence of lake morphometry and within-lake processes on diatom

Effects of recent climate change on phytoplankton phenology in a temperate lake

It was found that the centre of gravity of the spring chlorophyll a bloom advanced significantly and the shift in timing was attributed to an advance in the timing of the dominant spring diatom, Aulacoseira spp.

Life‐history traits of lake plankton species may govern their phenological response to climate warming

It is shown that the detailed seasonal pattern of warming influences the response of phyto- and zooplankton species to climate change, and point to the diverse nature of responses for species exhibiting complex life-history traits.

Nutrient limitation status of Arctic lakes affects the responses of Cyclotella sensu lato diatom species to light: implications for distribution patterns

It is found that light affected Cyclotella growth rates, cell densities, and distribution patterns differently depending on lake nutrient limitation status, and helps to clarify some of the complex distribution patterns of planktonic diatom taxa found in lakes of many areas around the Arctic as well as at lower latitudes.
