A new species of Cladocera, Alona begoniae sp. nov. (Anomopoda: Chydoridae) was found in ancient Lake Ohrid. Its habitus and outer morphology is similar to one the most common Palearctic species, Coronatella rectangula (Sars, 1862), this can be main reason why it has remained undiscovered. A. belongs elegans-group s. lato, a relict genus-level group not formally recognised yet as separate taxonomical unit. habitat appears sandy stony substrates (at 2-12 m depth) bare vegetation. The position...
Hydroclimatic variability is expected to be affected by global warming in the Mediterranean region where climate, fire and human activities are known interdependent. The latter examined here for past millennium studying paleoenvironmental indicators from a sedimentary sequence at Lagunillo del Tejo (Cuenca, central Spain). Inferred changes activity lake levels based on records of macrocharcoals plant/algal macrofossils, respectively, compared with independent information climate change...
Obtaining accurate temperature reconstructions from the past is crucial in understanding consequences of changes external climate forcings, such as orbital-scale insolation or multidecadal to centennial-scale variability on system and environment. In addition, these help comprehending amplitude natural past, which can assist evaluating rate recent anthropogenic global warming. Here we present first detailed Holocene mean July air reconstruction based chironomid assemblages sediments...
Cladocera (Crustacea: Branchiopoda) biodiversity was examined in sediment assemblages La Tembladera Lake, on the southern coast of Ecuador. We found remains from 14 taxa belonging to three families: Sididae, Daphnidae and Chydoridae. One taxon is planktonic ( Ceriodaphnia spp.) 13 are littoral Sarsilatona serricauda , Chydorus sp., Dunhevenia Leberis Alona Magnospina dentifera Kurzia Acroperus tupinamba Camptocercus Oxyurella longicaudis Leydigiopsis Euryalona sp. Notoalona cf. sculpta )....
A combination of microfossil assemblages, abundance fossil ephippia and mean body size provides the longest paleoclimatic reconstruction based on cladoceran subfossils in Iberian Peninsula. Species turnover Laguna de Río Seco (Sierra Nevada, southern Spain) was controlled by changes lake levels response to fluctuations hydroclimatic variability over last ∼8600 years. Our archive documents a wet period Early Middle Holocene (∼8600–5000 cal yr BP), characterized eurytopic plant-associated...
The body size of aquatic invertebrates is, to a great extent, dependent on ambient temperature, but distributions are also determined by other factors like food supply and predation. effect temperature organisms is formulated in the temperature–size hypothesis, which predicts smaller with increasing temperature. In this study, subfossil remains three littoral Cladocera (Alona affnis, A. quadrangularis, Chydorus cf. sphaericus) was investigated. Exoskeletal these species can be found large...
ABSTRACT Lake level reconstructions from a littoral core in lake El Tobar, Spain, are presented for the last 350 years. These based on plant macrofossils and stable isotopes lacustrine carbonates. Our data suggest five episodes of advance regression shoreline coupled with changes water retention lake. A low high renewal episode at ca . AD 1650–1715 is indicated by oxidized facies abundant remains terrestrial/marsh δ 18 O 13 C values. fluctuating 1715–1772 during changing climatic conditions...
Is there a bias between contemporary and subfossil cladoceran assemblages?Sediment water samples differ in both temporal spatial resolution.In this study, we compare set of covering the past 30 years with sedimentary sequence from surficial core spanning same period.More species were found sediment than samples.This result reflects accumulative integrative consequences sedimentation processes.For example, Alona quadrangularis, affinis, Pleuroxus truncatus Tretocephala ambigua only...
Ancient lakes contain unique and very vulnerable fauna. Determining understanding the origin of such biodiversity is a key factor in promoting conservation management actions some most singular ecosystems on planet. Lake Ohrid Balkans known as natural laboratory for speciation, containing high number endemic species. However, identity planktonic cladoceran
Due to similarities in morphological features together with strong dispersal abilities, it was thought that some groups of zooplankton (e.g. rotifers, copepods, and cladocerans) have cosmopolitan distributions. In the particular case cladocerans, recent molecular studies using DNA barcode regions indicated a different picture, including existence multiple regional endemic species geographical phylogroups; even at very small scales. This has demostrated cladocera are less widely distributed...
Sedimentation in most glacial lakes and wetlands the Sierra Nevada (southern Iberian Peninsula) occurred after last deglaciation since Younger Dryas (YD)-Early Holocene (EH) transition. Therefore, until now, studies on older sedimentary records were lacking this alpine area, which limits paleoenvironmental paleoclimatic information to Holocene. In study, we studied palynomorphs from record Laguna Seca (LS), longest oldest (~18000 cal yr BP = 18 kyr) investigate response of forests lake...
Abstract Available DNA barcodes of freshwater zooplankton are scarce in regions like the Iberian Peninsula, which harbours many rare and endemic species is considered a hotspot crustacean biodiversity. Recently, new Ceriodaphnia (Cladocera: Daphniidae) was described using morphological analysis specimens Mediterranean region molecular data on single locality southern Spain. In our study, we detected presence newly discovered taxa here, provide sequences barcoding mitochondrial cytochrome c...
