Figure 3 in Congruent patterns of lineage diversity in two species complexes of planktonic crustaceans, Daphnia longispina (Cladocera) and Eucyclops serrulatus (Copepoda), in East European mountain lakes

Figure 3. Relationship of eight clades of the Eucyclops serrulatus complex, assessed by Bayesian inference of phylogeny, and haplotype variation of the 12S rRNA gene within clade I. The phylogenetic tree was based on the 1299-bp-long alignment consisting of fragments of mitochondrial genes for 12S rRNA and cytochrome b, and the nuclear gene for 18S rRNA. The scale bar represents genetic distance; numbers at nodes indicate branch support (as posterior probabilities). Haplotype network representing the variation within clade I is based on 43 sequences of the 383-bp-long 12S rDNA fragment. Individuals from the three main mountain regions are indicated by different shading (as in Figs 1, 2) in both tree and network: the Carpathians in dark grey (N = 24), Macedonian-Thracian massif in white (N = 9), and Dinaric Alps in light grey (N = 26). Mountain range abbreviations: Bje, Bjelasica; Dur, Durmitor; Pir, Pirin; Pro, Prokletije; Ret, Retezat; Ril, Rila; Sar, Šar Planina; Tat, Tatra Mountains; Tre, Treskavica; Zel, Zelengora. Countries are indicated by two-letter codes (see Table 1).

Figure 2 in Congruent patterns of lineage diversity in two species complexes of planktonic crustaceans, Daphnia longispina (Cladocera) and Eucyclops serrulatus (Copepoda), in East European mountain lakes

Figure 2. Sequence variation of the 528-bp-long fragment of the 12S rRNA gene within the Daphnia longispina complex from lakes of the studied East European mountain ranges. This is shown in a maximum likelihood tree (A) consisting only of sequences from the studied region (each haplotype represented once per lake), and in a parsimony network (B) of haplotypes of D. longispina s.s., amongst which 63 reference sequences from other European localities were also included. Three main mountain regions from this study are differentiated by shading: the Carpathians in dark grey, Macedonian-Thracian massif in white, and Dinaric Alps in light grey. Haplotypes from other localities, only included in the network, are enclosed by dashed lines. Mountain range abbreviations: Bje, Bjelasica; Dur, Durmitor; Pir, Pirin; Pro, Prokletije; Ret, Retezat; Ril, Rila; Tat, Tatra Mountains; Tre, Treskavica; Zel, Zelengora. Countries are indicated by two-letter codes (see Table 1).

Abundance, Biovolume, and Biomass of Synechococcus and Eukaryote Pico- and Nano- Plankton From Continuous Underway Flow Cytometry During NES-LTER Transect Cruises, Ongoing Since 2018

<p>"These data represent the abundance, biovolume, and biomass of prokaryotic and eukaryotic picoplankton and nanoplankton sampled continuously underway during Northeast U.S. Shelf Long-Term Ecological Research (NES-LTER) Transect cruises, ongoing since 2018. Samples were obtained with an Attune NxT Flow Cytometer sampling at approximately 2-min intervals from the underway science seawater. Cells were identified and enumerated from the flow cytometry data files based on their scattering, phycoerythrin (575 nm) and chlorophyll (680 nm) fluorescence signals."
