Phylogenetic data for the description eight new Halophytophthora species and an updated phylogeny for the genus
<p><span>During an oomycete survey in December 2015 ten previously unknown <em>Halophytophthora</em> taxa were isolated from marine and brackish water of tidal ponds and channels in saltmarshes, lagoon ecosystems and river estuaries at seven sites along the Algarve coast in the South of Portugal. Phylogenetic analyses of LSU and ITS datasets, comprising all described <em>Halophytophthora</em> species, the ten new <em>Halophytophthora</em> taxa from Portugal and all relevant and distinctive sequences available from GenBank, provided an updated phylogeny of the genus <em>Halophytophthora</em> s. str. showing for the first time a structure of ten clades designated as Clades 1–10. Nine of the ten new <em>Halophytophthora</em> taxa resided in Clade 6. Based on differences in morphology and temperature-growth relations and a multigene (LSU, ITS, <em>Btub</em>, <em>hsp90</em>, <em>rpl10</em>, <em>tigA</em>, <em>cox</em><em>1</em>, <em>nadh1</em>, <em>rps10</em>) phylogeny eight new <em>Halophytophthora</em> taxa from Portugal are described here as <em>H. brevisporangia</em>, <em>H. celeris</em>, <em>H. frigida</em>, <em>H. lateralis</em>, <em>H. lusitanica</em>, <em>H. macrosporangia</em>, <em>H. sinuata</em> and <em>H. thermoambigua</em>. Three species, <em>H. frigida</em>, <em>H. macrosporangia</em> and <em>H. sinuata</em>, have a homothallic breeding system while the remaining five species are sterile. Pathogenicity and litter decomposition tests are underway to clarify their pathological and ecological role in the marine and brackish-water ecosystems. More oomycete surveys in yet undersurveyed regions of the world and populationgenetic or phylogenomic analyses of global populations are needed to clarify the origin of the new <em>Halophytophthora</em> species.</span></p>

Data from: A new approach for investigating spatial relationships of ichnofossils: a case study of Ediacaran–Cambrian animal traces
<p class="MsoNormal"><span class="Heading1Char"><em>Abstract — </em></span>Trace fossils record foraging behaviours, the search for resources in patchy environments, of animals in the rock record. Quantification of the strength, density and nature of foraging behaviours enables the investigation of how these may have changed through time. Here, we present a novel approach to explore such patterns using spatial point process analyses to quantify the scale and strength of ichnofossil spatial distributions on horizontal bedding planes. To demonstrate the utility of this approach we use two samples from the terminal Ediacaran Shibantan Member in South China (between 551 and 543 Ma) and the early Cambrian Nagaur Sandstone in northwestern India (between 539 and 509 Ma). We find that ichnotaxa on both surfaces exhibited significant non-homogeneous lateral patterns, with distinct levels of heterogeneity exhibited by different types of trace fossils. In the Shibantan, two ichnotaxa show evidence for mutual positive aggregation over a shared resource, suggesting the ability to focus on optimal resource areas. Trace fossils from the Nagaur Sandstone exhibit more sophisticated foraging behaviour, with greater niche differentiation. Critically, mark correlation functions highlight significant spatial autocorrelation of trace fossil orientations, demonstrating the greater ability of these Cambrian tracemakers to focus on optimal patches. Despite potential limitations, these analyses hint at changes in the development and optimisation of foraging at the Ediacaran–Cambrian transition and highlight the potential of spatial point process analysis to tease apart subtle differences in behaviour in the trace fossil record.</p>
Data from: A new composite abundance metric detects stream fish declines and community homogenization during six decades of invasions
<p><b>Aim</b>:<b> </b>We developed a new technique, utilizing species-specific counts of individuals from historical fish community samples, to examine landscape-level, spatiotemporal trends in relative abundance distributions. Abundance-based historical distribution analyses are often plagued by data comparability issues, but provide critical information about community composition trends inaccessible to those using analyses based only on species presence-absence. We established trends in native and non-native fish abundance and community homogenization, uniqueness, and diversity to help local conservation managers prioritize targets and motivate similar studies globally to support fish conservation.</p> <p><b>Location</b>: Upper and middle New River (UMNR) basin, Appalachian Mountains, USA.</p> <p><b>Methods</b>: We compiled catch data from 61 years of fish community surveys (1958-2019) and tested for community homogenization by comparing data from repeatedly sampled sites (1900s versus 2000s samples) using dispersion analyses. We measured community uniqueness (site contributions to beta diversity) and species diversity (Shannon index) at sampled streams to identify potential conservation hotspots. We then used regression analyses and Wilcoxon signed-rank tests to examine species-specific basin-wide and local abundance trends and identify species of potential conservation concern.</p> <p><b>Results</b>: Dispersion of sites in species-abundance space was significantly greater in the 1900s compared to the 2000s, indicating homogenization had occurred. Of 36 native species analyzed, 44.4% (16) showed basin-wide declines. Non-native species exhibited mixed patterns; site-level abundance increased in 2 of 15 species analyzed (13%).</p> <p><b>Main conclusions</b>: Our results indicate basin-wide community homogenization has occurred within the UMNR, but many unique and diverse communities persist. If conserved, these could help maintain regional fish diversity. We found basin-wide declines in four endemic species, as well as spread patterns of non-native and native species that were not detected by a presence-absence analysis applied within the same study area. This finding illustrates the importance of considering both species' abundance and occurrence patterns as separate dimensions of biodiversity to inform conservation planning.</p>
