Hydroperiod length, not pond age, determines zooplankton taxonomic and functional diversity in temporary ponds

Ecological Indicators, Год журнала: 2024, Номер 159, С. 111632 - 111632

Mediterranean Temporary ponds (MTPs) are suffering severe alterations in their hydrological and salinity regime through global change, restoration or conservation of these habitats is a priority. However, there little information that can be used as scientific basis for restoration. We studied the taxonomic functional diversity zooplankton communities set 96 Doñana, Spain during four consecutive hydroperiods after creation. examined differences across alpha beta (and its turnover nestedness components) rotifer, cladoceran copepod community, well influence local environmental variables including proximity to natural wetlands. There was no general increase indices first two hydroperiods. found shorter significantly reduced diversity, but increased contribution turnover. Shorter also community complexity, with long-term effects. Conductivity most important predictor direction effects changed between The distance from source colonists, pond depth, were key early stage assembly perturbation. Our results suggest new projects MTPs should focus on increasing heterogeneity reducing vulnerability salinization. use approaches monitoring studies improve our understanding mechanisms processes affecting under dynamic regimes. This turn help us predict consequences management policies biodiversity MTPs.

Amazon streams present great biodiversity and offer several ecosystem services, but these systems are threatened by multiple land uses. The changes created use expected to drive the composition of species, ultimately changing trophic relationships biological groups, including zooplankton. We investigated if zooplankton functional guilds in which local (physical-chemical) variables driving land-use gradient.

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)

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.
