Abstract Mine pit lakes are formed when open‐cut pits flood with water, and these occur by the thousands on every inhabited continent. The remediation closure of is a pressing issue for sustainable development provision freshwater ecosystem services. While can be spectacular examples recreation renewal, may better known their poor water qualities risks to communities environment. Often public wants simply “fill in” restore terrestrial landscape, but this not always possible. Therefore, planning future uses likely provide best outcome. Poor quality necessarily barrier use, although it limit number uses. Short‐term tend require commercial viability, active infrastructure investment, maintenance, should transition complementary long‐term that promote biodiversity. Long‐term relatively less ongoing maintenance beyond initial investment adhere principles safe, sustainable, non‐polluting in perpetuity. Pit will eventually develop “ecosystem values,” time do so depends nature intervention values ascribed community. Where possible, closing as ecosystems most realistic goal permits variety see valued generations. This article categorized under: Engineering Water > Planning Human Value Imagined Represented

Zooplankton network conditioned by turbidity gradient in small anthropogenic reservoirs

Scientific Reports, Год журнала: 2022, Номер 12(1)

Опубликована: Март 10, 2022

Abstract Water turbidity can significantly influence interspecific interactions in aquatic ecosystems. We tested the hypothesis that gradient differentiates dynamics, significance and type of relationships structure zooplankton communities colonizing mine pit reservoirs. The between species were evaluated by network graph analysis for three water classes: high (HT), moderate (MT) low (LT). HT was most cohesive, it controlled taxa grazing on various food sources within one ecological niche ( Polyarthra longiremis , Brachionus angularis Cyclops vicinus Codonella cratera ) positive negative them balanced. MT biocenotic composed sub-networks connected nodes with communication attributes vulgaris Bosmina longirostris C. ), antagonistic (predation competition) less important. LT heterogeneous, Daphnia cuculllata exerted strongest network’s forming numerous (coexistence predators) (interference competition microphagous rotifers) relationships. study provides new information about ecology ecosystems, are disturbed changes turbidity.

Perceptions of a Water Reservoir Construction Project Among the Local Community and Potential Tourists and Visitors

A study was conducted concerning the perceptions of a future reservoir (4.7–8.9 square kilometres, 42.2 million cubic metres) by residents, tourists, and visitors; location in question former Kotlarnia sand pit catchment area Bierawka River (tributary Oder southern Poland). Divergent concepts for reclamation development emerged; construction initially dominant option but eventually abandoned despite it having greatest acceptance among respondents (out 134 respondents, 43.3% favoured creation water reservoir, 29.9% introducing nature protection arrangements to enable spontaneous regeneration, 16.4% reforestation). clear discrepancy arose between public’s expectations related order create official position land user administrator potential which indicated that no longer intended such reservoir. This indicates process developing mineral workings, is essential obtain results public consultation based on diagnostic survey representatives local community. an effective tool predicting optimal use sites regenerated after damage caused open-pit mining provided all technical considerations planned project are taken into account advance.

Deep lakes support higher zooplankton functional diversity than shallow lakes: A case study in lacustrine environments affected by mining tailings (lower Doce River basin, Brazil)

Freshwater Biology, Год журнала: 2024, Номер 69(7), С. 945 - 958

Опубликована: Май 23, 2024

Abstract Tragic incidents involving mine tailings spills have impacted many aquatic ecosystems around the world. The massive dam collapse of Fundão, which occurred in Brazil 2015, affected several ecosystems, including shallow and deep lakes lower Doce River basin. Until now, effects on functional diversity zooplankton remain poorly understood. We investigated (functional groups, richness [FRic] evenness [FEve]) lakes, exploring influence environmental variables metals. In addition, trends redundancy vulnerability were also assessed to understand patterns resilience mining‐impacted ecosystems. Surveys performed monthly three by failure, from October 2018 September 2019. community was dominated smaller filter‐feeders omnivorous species, associated with cyanobacteria density chlorophyll‐ a .

Deciphering the Patterns and Correlates of Zooplankton Functional Diversity in Mountain and Lowland Ponds

Freshwater Biology, Год журнала: 2025, Номер 70(1)

ABSTRACT Biodiversity studies have usually been conducted considering only the taxonomic dimension of ecological communities. However, diversity measurements taking into account functional traits species may be more sensitive in capturing aspects community functioning that are not apparent with traditional approach. Functional (either based on alpha or beta levels) is, therefore, a facet provides link between ecosystem and structure an important metric for assessing impact global change context applied conservation schemes. Zooplankton is key element lentic ecosystems due to its linkage primary producers secondary consumers. Here, we tried disentangle spatial patterns correlates zooplankton along relatively wide altitudinal gradient (700–2100 m a.s.l.) across central northwestern Spain. We also identified environmental controls extensive set lowland (48) mountain (28) ponds sampled 2004–2005 2007–2008, respectively. assessed whether replacement richness differences drove overall evaluated relative contributions geographical distances variation diversity.

Trait-Based Research on Rotifera: The Holy Grail or Just Messy?

Water, Год журнала: 2023, Номер 15(8), С. 1459 - 1459

Опубликована: Апрель 8, 2023

In recent years, trait-based research on plankton has gained interest because of its potential to uncover general roles in ecology. While trait categories for phytoplankton and crustaceans have been posited, rotifer assessment lagged behind. Here, we reviewed the literature assess traits key their life histories provided a data matrix 138 valid genera phylum Rotifera. We considered seven traits: habitat type, trophi presence lorica foot, predation defense attributes, corona feeding traits. most were morphological attributes supposedly easy assess, faced with several challenges regarding assignment. Feeding especially difficult many relevant information was missing. Our assembled provides foundation that will initiate additional functional diversity, diminish misclassification into categories, facilitate studies across trophic levels.
