Abstract Estimating organisms' responses to environmental variables and taxon associations across broad spatial scales is vital for predicting their climate change. Macroinvertebrates play a major role in wetland processes, but studies simultaneously exploring both community structure trait gradients are still lacking. We compiled global dataset (six continents) from 756 depressional wetlands, including the occurrence of 96 macroinvertebrate families, phylogenetic tree, 19 biological traits....
Nitellopsis obtusa usually inhabits deep lakes, where the plants display vegetative growth and survive through winter. In present study we investigated a shallow lake reproduces sexually; were interested in effect of light conditions, temperature water level on sexual reproduction species its ability to lakebed drying. We estimated distribution all macrophyte each July from 2009 2014 correlated annual variations with fluctuations hydrological conditions. also sampled variety morphological...
Ponds occupy a large share of standing water worldwide and play an important role in providing various ecosystem services. There are concerted efforts the European Union either to create new ponds, or restore preserve existing ponds as nature-based solutions provide benefits human well-being. As part EU PONDERFUL project, selected pondscapes (i.e. landscapes ponds) eight different countries – hereafter "demo-sites", studied comprehensively understand their characteristics efficiency In...
We contest the recently reported findings that suggest presence of female gametangia in North American range invasive macroalga Nitellopsis obtusa (Harrow-Lyle, T.J., Ginn, B.K., Kirkwood, A.E., and Melles, S.J. 2023. First report starry stonewort ( obtusa) America. Botany, 101: 61–64. doi:10.1139/cjb-2022-0096). The claims do not clearly show identifying morphology N. gametangia, are inconsistent with known characeaen developmental biology, provide evidence commensurate such a claim. More...
Nature-based solutions (NBS) are increasingly suggested to address biodiversity decline and climate change. However, many ecosystems hardly used as NBS, including ponds pondscapes. We therefore examine how policies practices affect their implementation NBS. Using a content analysis of policy documents stakeholder inputs, we assess the context in eight countries but also zoom on seventeen derive three key insights: first, protective status for pond or pondscape interlinks with other enabling...
The study addressed the ecology and life cycle of two charophyte species, which are both at risk extinction on several Red Lists in Europe. Populations Nitella opaca N. gracilis, sometimes occurring together three wetland ponds, were monitored for years, environmental data also recorded. pattern timing emergence (new shoots) maturation sexual organs (antheridia, oogonia, ripe oospores) determined plant samples collected regularly. species phenophases related to data. results showed that...
The paper describes the discovery of a species genus Chara, hitherto unknown in France. morphological features plants and oospores are shown identify plant as Chara fibrosa ssp. benthamii, tropical taxon, non-native to European Charophyte flora. ecological conditions this particular find correspond an artificial temporary pond located Crau plain, north Camargue. In contrast normal hydrological cycle ruled by local precipitation during winter, studied is flooded from irrigation water late...
