Data from: Genomic signatures of paleodrainages in a freshwater fish along the southeastern coast of Brazil: genetic structure reflects past riverine properties
Past shifts in connectivity in riverine environments (for example, sea-level changes) and the properties of current drainages can act as drivers of genetic structure and demographic processes in riverine population of fishes. However, it is unclear whether the same river properties that structure variation on recent timescales will also leave similar genomic signatures that reflect paleodrainage properties. By characterizing genetic structure in a freshwater fish species (Hollandichthys multifasciatus) from a system of basins along the Atlantic coast of Brazil we test for the effects of paleodrainages caused by sea-level changes during the Pleistocene. Given that the paleodrainage properties differ along the Brazilian coast, we also evaluate whether estimated genetic diversity within paleodrainages can be explained by past riverine properties (i.e., area and number of rivers in a paleodrainage). Our results demonstrate that genetic structure between populations is not just highly concordant with paleodrainages, but that differences in the genetic diversity among paleodrainages correspond to the joint effect of differences in the area encompassed by, and the number of rivers, within a paleodrainage. Our findings extend the influence of current riverine properties on genetic diversity to those associated with past paleodrainage properties. We discuss how these findings may explain the inconsistent support for paleodrainages in structuring divergence from different global regions and the importance of taking into account past conditions for understanding the high species diversity of freshwater fish that we currently observe in the world, and especially in the Neotropics.
Data from: Riverine transport and nutrient inputs affect phytoplankton communities in a coastal embayment
<p>1. Rivers often transport phytoplankton to coastal embayments and introduce nutrients that can enrich coastal plankton communities. We investigated the effects of the Nottawasaga River on the nearshore (i.e., within 500 m of shore) phytoplankton composition along a 10 km transect of Nottawasaga Bay, Lake Huron in 2015 and 2016. Imaging flow cytometry was used to identify and enumerate algal taxa, which were resolved at sizes larger than small nanoplankton (i.e., > 5 mm). Multivariate analysis (perMANOVA and RDA) and a dilution model were used to examine how nutrients and the transport of algal taxa affected community composition in the bay.</p> <p>2. Sampling stations with different percentages of river water had significantly different phytoplankton communities. Phytoplankton community composition was also strongly associated with nutrients, including total phosphorus, which also varied with the percentage of river water. The majority of the 51 phytoplankton taxa identified in 2016 had numerical abundances in the bay that could be explained simply by the dilution of incoming river water.</p> <p>3. Phytoplankton transported from the river had a higher proportion of "edible-sized" cells (< 30 mm), particularly in summer when colonial cyanobacteria were numerically dominant in the bay. Six taxa were more abundant than expected from the dilution of river water and included some cyanobacteria with late summer maxima. Five of the taxa that were transported from the river were less abundant than expected in the bay.</p> <p>4. Whereas impacts of fertilization due to the characteristically higher nutrient concentration in the river are to be expected, the strong and highly correlated effects of transport within the narrow coastal band of this study largely concealed any distinct fertilization effects.</p> <p>5. Riverine inputs may strongly influence the near-shore assemblage of phytoplankton in oligotrophic embayments in large lakes, creating hotspots for productivity, species turnover and trophic dynamics.</p>
Figure 22. Male M in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)
Figure 22. Male M. nigromaculatus displaying as it stepped from side to side directly in front of a female. This sequence (1- 20) includes selected sequential frames from a 25 fps video. Arrows indicate the moderate rotation of the opisthosoma and bilateral waving of legs I that accompanied this rapid stepping movement (also indicated by arrows). As with M. chrysomelas (Figure 20), pedipalps were held to the sides of the chelicerae and moved little during this display.
Figure 21 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)
Figure 21. Composite images showing sequential positions (1-19, selected from 25 fps video frames) of a male M. nigromaculatus running rapidly from one side to the other of a female that he was facing.
Figure 20 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)
Figure 20. Courtship display by a male M. chrysomelas from Cape Le Grand near Esperance, WA. Selected, sequential frames from a 25 fps video are shown. Movement of the legs (bilateral waving) and pedipalps (raising and lowering), limited rotation of the elevated fan, and side-stepping are highlighted with arrows. There was little independent movement of the fan.
Figure 18 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)
Figure 18. Four different male Maratus nigromaculatus (1, 2-4, 5, 6-7), recently rediscovered in the vicinity of Brisbane. Keyserling (1883) also described this spider from 'Rockhampton', but no other localities are known. The spiders shown here (and in Figures 21-23) were either collected at Nudgee Beach Reserve in Brisbane, or reared from eggs produced by females collected at that site. This appears to be a coastal species, living amongst grass or pig face plants (Carpobrotus) along the borders of estuaries.
Figure 17 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)
Figure 17. Courtship display by two male Maratus chrysomelas from Western Australia. The opisthosoma of the male from Cape Le Grand near Esperance (5-7) on the southwestern coast was wider than that of the male from Warwick Open Reserve near Perth (1-4; 31.837 S, 115.8163 E). Note the expansion of the elevated and flattened opisthosoma to reveal a fringe that is much narrower than that of male M. nigromaculatus (Figure 18). As in the latter species, the bright white pedipalps were held apart to reveal the dark, glabrous chelicerae during display.

Figure 19 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)
Figure 19. Fourteen different male Maratus photographed in their natural habitat, a grassy patch in Emerald, Queensland. Several males in this group (1-2) look like typical M. chrysomelas, while others exhibit the wider fringes and dark spots or (at the posterior) dashes on the dorsal plate characteristic of M. nigromaculatus, or something intermediate between the two species. This may represent gene introgression from that closely-related species into a nearby population of M. chrysomelas. Photographs copyright © Laurence Sanders, used with permission.

Figure 23. Male M. nigromaculatus displaying in place directly in front of a female at a distance of ~1 cm. Consecutive frames from a 25 fps video are shown. Some bilateral waving of legs I (5-6), and very limited up and down movement of the pedipalps (38) can be seen. The main movement was side-to-side rotation of the elevated and expanded fan cycling at a rate of ~2/s.

Photographs of courtship display by the holotype (1-3) and paratype (4-9) male Maratus fimbriatus. 7-8, Note the distinct separation of the 'pom pom' distal pedipalps from the dark, glabrous proximal pedipalps and chelicerae. The anterior surface of femora I is glabrous and light brown or dark olive in colour dorsally.
