Introduction to Across Lake

Overall, our results suggest that the same genomic regions contribute to parallel integrated craniofacial phenotypes across lakes.

Assuming that phytoplankton production is light-limited in winter, we identified four patterns of OAB control across lake types and climate zones.

However, spatial and temporal integration is often underdeveloped because different paleolimnological measurements must be applied across lakes due to the wide range of energy conditions that impart marked differences in sediment composition.

However, composition is tied to a given lake, wherein samples from the same core were more alike than samples at similar depths across lakes.

A comparative exercise shows that taking into account the morphometry of lakes moderately increases the predictive power of empirical models of carbon concentration across lakes.

Across lakes, a continuum of physical (e.

We observed a significant negative trend of the co-occurrence patterns across lake area categories for predator-prey species, indicating that the effect of predation was stronger in smaller lakes, but it was reduced in larger lakes, possibly due to increased habitat and resource availability.

The relative abundance variation of dominant microbial groups across Lake Remoray such as Cyanobacteria, Gammaproteobacteria, Deltaproteobacteria and Chloroflexi provided us important information on the lake areas where hypoxia occurs.

Despite contemporaneous changes in pollen and pigment biomarkers across lakes, cores collected from adjacent basins of the same lake (Green Lake) did not show similar trends in fossil pigments likely reflecting preferential deposition of clay-rich allochthonous material in the deeper central basin and suggesting that regional signals in climate may be complicated by lake- or basin-specific catchment processes.

Diatom production was generally low across lakes prior to the 1800’s AD but has risen 1.

But, the anthropogenic forces affecting lake water quality (climate change, land use change, and invasive species) are unevenly distributed across lakes, across the seasonal cycle, and across space within lakes, potentially leading to highly variable water quality responses that are poorly documented at the global scale.

We investigated the diversity, composition, and assembly processes of sedimentary bacterial communities across Lake Taihu, China, a large, shallow, and eutrophic water body.

The potentially bio-available heavy metals were assessed in the bulk and the three fine fraction sediments (Ø3, Ø4, and Ø5) from 24 stations across Lake Burullus.

In Spring 2018, we conducted a binational ichthyoplankton assessment to describe the spatial extent of coregonine spawning habitat across Lake Ontario.

Overall, zooplankton communities were more similar across lakes under the ice than during the open water season.

However, little is known about the temporal responses of the zooplankton community to abiotic and biotic drivers across lakes at the regional scale.

Our study confirms the importance of O2 and CH4 in shaping the methanotrophic communities and suggests that one variable cannot explain the diversity and distribution of the methanotrophs across lakes.

The composition of both prokaryotic and the eukaryotic microbialite-associated communities varied significantly across lakes, correlating with the alkalinity and salinity gradient.

39) across lakes.

This research proposes an efficient computational technique for identifying bottom-fast ice across lakes in the Northwest Territories using multi-temporal SAR backscatter images and applies a function called dynamic time warping (DTW), which provides a shape-based similarity metric for time series data.

Our goal was to study the environmental drivers of REE levels in zooplankton, a key component in plankton food webs, across lakes from geographic areas with different bedrock geology.

Across lakes, there was a continuum of ecological, morphological, and genetic differentiation that could be associated with alternative resources and lake characteristics.

Results suggest that coordinated management across lakes provides its highest economic value in the early years of an invasion, before high-value, high-traffic lakes are invaded, and drops quickly once the invasion claims these lakes.

This study reports measurements of Hg concentrations from water collected in August 2013 and 2014 from across Lake Baikal and its main inflow, the Selenga River basin (Russia, Mongolia).

Current understanding is largely limited to description of changes in chemistry, with few measurements of the processes driving winter changes, how they differ across lakes, and how they are impacted by under-ice conditions.

This combined tracer approach allows the quantification of dietary proportions (using stable isotopes), which are then integrated using a novel PCB tracer approach that employs knowledge of PCB bioaccumulation pathways, to estimate consumption and quantify energy flow between age cohorts of individual fish across Lake Huron.

The lakes differed in limnological features, both within and across lake type; although the composition of molluscan assemblages were similar, abundances varied considerably.

Bangladesh has millions of hectors of potential sites across lakes, rivers and ponds, which can conduct high rates of nutrient uptake via phytoremediation, such as Nitrogen and Phosphorus, in industrial wastewater, and then be used to produce biofuels.

Additionally, through advances in sensor technology, observations of lake metabolic processes have been shown to be meaningfully heterogeneous both within and across lakes (Coloso et al.

vittatus and investigated whether within those species genetically separate populations occur across Lake Baikal.

Despite the known metabolic and ecological differences between the two MOB groups, their main environmental drivers and their relative contribution to CH4 oxidation rates across lakes remain unknown.

5 My old), in allopatry and sympatry (within and across lakes), and across the range of dietary niches (from highly specialized to generalist feeders).

We examined the extent to which spring migrants flew across Lake Erie as a continuation of the inland, northeasterly broad front migratory direction, as determined by weather radar and infrared observations, or displayed a tendency to deviate to more closely follow the direction of the coastline.

Throughout the study, the average value of the C:N:P ratio of 143:19:1 across Lake Taihu was close to the canonical lake’s ratios (166:20:1).

With the exception of sediment chemistry, biophysical variables were significantly different across lakes and reflected riparian condition and groundwater chemistry.

Additionally, it is expected that the seasonal lake group may exert an important role in influencing the surface hydrological connectivity and associated dry-wet hydrological shift across lake-floodplains, indicating a dominant role of the floodplain bathymetry changes.

Although survival surfaces favored alternate phenotypes between lakes, joint fitness estimation across lake environments supported multiple fitness peaks for generalist and molluscivore phenotypes and a large fitness valley isolating the most divergent scale-eater phenotype, strikingly similar to a previous independent field experiment.

Over 37% of genomic windows are repeatedly differentiated across lake–stream pairs.

It has also evolved in parallel across lakes in East Africa and Central America.

However, the estimated contribution of different production sources to fish biomass varied, on average, by ∼40% across lake systems.

These results highlight the importance of accounting for detectability when comparing estimates over time or across lakes, particularly when different observers conduct surveys.

This study quantified the extent of water quality degradation across lake types at a national scale, thereby informing ecological restoration objectives and the potential to reduce anthropogenic nutrient loads, while also providing a modeling framework that can be applied to lakes elsewhere.

The conference began with dinner and with a welcome address delivered by Professor Gouverneur from the balcony overlooking the ornate Fronaap-Saal, with high ceilings and large windows looking out across Lake Lucerne towards snow-topped mountains.

However, there were no specific differences in PAEs across lake zones and river types of Lake Chaohu.

Surface waters are projected to warm, with a median warming across lakes of about 2.

Metals such as cadmium (Cd), zinc (Zn) and arsenic (As) are found at relatively low concentrations until a clear increase is observed after 1950s across lakes.

In late 2018, unusual patterns of very high mortality (>50% production) were reported in intensive tilapia cage culture systems across Lake Volta in Ghana.

Third, ecological factors resulting in variation across lakes in juvenile survival rates avoided the systematic overexploitation of ecologically more productive systems.

AIM: To discover how biological traits, ecological preferences and taxonomic relatedness are associated with occupancy and abundance of diatom species across lakes and streams.

In this study, we used results from whole-lake studies in northern Sweden to show that annual mean phytoplankton biomass expressed unimodal curved relationships across lake DOC gradients, peaking at threshold DOC levels of around 11 mg/L.
