Using Macroinvertebrates to Test the Water Quality of Lake Nacogdoches [PDF]

, 2019
The target of this assessment was to conduct a water quality test on Lake Nacogdoches in Nacogdoches TX. Lake Nacogdoches is operated by the city of Nacogdoches for municipal water supply and recreation.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

Conservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Prey DNA Detection in Lycosid Spiders Is Primarily Influenced by Time Since Feeding and Primer Choice

Entomologia Experimentalis et Applicata, EarlyView.
Gut content analysis using DNA metabarcoding has improved understanding of predator–prey interactions involving spiders. We tested how starvation before feeding, time since feeding, spider size, and the presence of egg sacs or spiderlings affect prey DNA detection in Lycosidae.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Ecological integrity of boreal streams [PDF]

, 2007
Running waters provide a number of services for humans, such as drinking water and food resources and many freshwater animals are confined and specialised to this environment.

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

Journal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

The Colonization of Newly Built Fishponds by the Macroinvertebrate Assemblages

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016
The succession of standing waters by aquatic macroinvertebrates is a present and insufficiently surveyed topic. This study is addressed to the issue of colonisation of newly created small standing waters.
