Nucula (Nuculidae, Bivalvia) from upper bathyal depths off Namibia
No full textThree species were found from the continental slope off Namibia of which two species are new to science: Nucula kunenensis n. sp. and N. nama n. sp. A comparison was made with morphologically similar eastern Atlantic and South African species in the family Nuculidae. Nucula kunenensis n. sp. was found alive in silty sediment with high organic content in upper bathyal depths off the Kunene region in NW Namibia. Nucula nama n. sp. is only known from a single living individual taken in a similar environment. The two new species have a distinctive ribbing on the prodissoconch which differs both from most
coastal Nucula spp. and most of the South African species. We believe this should be emphasized as an indication of a hitherto neglected but apparently useful character of some deep-water Atlantic nuculid species
BLOOM campaign - Remote sensing datasets
No full text<p>This repository contains datasets from the remote sensing instrumentation used during the BLOOM (turBulence and oLea pOllen prOperties experiMent) campaign. This campaign took place from May 18 to June 21 2022, at the Guadiana-UGR station (37.91ºN, 3.23ºW, 370 m asl) in Southern Spain, within the framework of the INTEGRATYON3 project (PID2020-117825GB-C21 and PID2020-117825GB-C22), funded by MCIN/AEI/10.13039/501100011033.</p>
<p>The primary focus of the campaign was to investigate olive tree pollen emissions and characterize aerosol particles and greenhouse gas exchanges in an olive field.

A mixed method approach towards the evaluation and assessment of integrative research programme outputs: The case of the Invasive Alien Plant management programme Working for Water
No full textThe pervasiveness of threats posed by biological invasions presents significant challenges to human well-being, biodiversity conservation, and natural resource management, which has contributed to the growth of invasion science as a discipline. However, several studies have shown that the social-ecological complexity of invasions, the compartmentalisation of knowledge into disciplines and the lack of integrative research approaches, current invasion research has not informed management decision making effectively. Thus, to maximise the impact of research investments, there is a need to explore and evaluate how research informs management practices and processes linked to biological invasions. Accordingly, this dissertation outlines the state of invasion management-related research in South Africa, using the internationally recognised Working for Water (WfW) programme as a case study. Drawing on insights from science studies and evaluation research, a mixed-method approach is used to assess the processes, conditions and outputs associated with research produced under the programme’s auspices. The research comprised two areas of inquiry 1) the exploration of textual information (journal articles, grey literature, and their content), and 2) the social dimensions of research and decision making linked to invasion science and management, with a specific focus on collaborative relationships amongst scientists and decision makers. It sought to determine the extent to which published research aligned with the programme’s needs, research and management strategies. The research also aimed to identify effective ways for organising and producing knowledge relevant to decision making; and to provide insights into how the social dimensions, the people and organisations, their interactions and impact, have shaped research and decision-making processes. Findings suggest that there are significant gaps in the knowledge base particularly in relation to the social dimensions of biological invasions, which were poorly represented and aligned with the mandate and priorities set by the programme. This research showed significant deficiencies in knowledge management and the uptake of research funded by the programme, despite its potential relevance to decision making as evidenced by the recommendations presented in the research. Moreover, research produced under WfW’s auspices was authored by a handful of key researchers who fulfil a significant role in shaping research collaborations both across disciplines and institutions. The loss of these key individuals, including those involved in management-related decision making, would be detrimental to the stability of collaboration networks and research productivity. Finally, findings show that research productivity, collaborative relationships between scientists within and across research organisations, and between research and decision-making processes are positively influenced by collegiality and cooperation between actors, while increased competition and bureaucratisation in the workplace negatively influence research productivity. To address the shortcomings concerning the invasion research and management identified in this dissertation, efforts towards improving the relationship between researchers and decision-makers and building more resilient collaboration networks need to be implemented. Firstly, institutions must engage in and fund more targeted, long-term transdisciplinary or integrative research that incorporates appropriate structures that foster collaboration, knowledge coproduction and knowledge sharing. Secondly, systems and strategies for monitoring and evaluating research, including the use of bibliometric indicators, social network analyses and qualitative assessments, should be developed to ensure that research relevant to managing biological invasions is not lost to the decision-making process. Such an undertaking would in turn require the development of an integrated research strategy and action plan that accounts for both the knowledge management and the social processes underpinning research and decision making

No full text<p>R code (.R), RData (.RData), and .csv files related to the analysis of curatedMetagenomicData datasets (https://waldronlab.io/curatedMetagenomicData/). The purpose of this analysis was to assess the prevalence of <em>Enterocloster</em> spp. capable of metabolizing urolithin C in human stool metagenomic sequencing experiments (https://waldronlab.io/curatedMetagenomicData/articles/available-studies.html). </p>
<p>The data were generated/analyzed in the following way:</p>
<p>1 - 1_ExperimentHub_Local_Cache_Export.R was used to generate .RData files for all 93 studies are available in curatedMetagenomicData. The resulting files (.RData) generated are named according to the following convention: Studies##-##.RData.</p>
<p>2 - The Studies##-##.RData files were loaded into an R environment in the Narval compute cluster (Digital Research Alliance of Canada) and the 2_cMD_FromRData.R script was used to query the relative abundance (ra) of bacteria of interest (boi) and the gene families abundance (gf) for genes of interest (goi). Metadata (md) was also extracted from each study. The resulting files (.csv) generated are named according to the following convention: Study##_datatype.csv (datatype = ra_boi, gf_goi, md).</p>
<p>3 - The Study##_datatype.csv (datatype = ra_boi, gf_goi, md) files were then analyzed using the 3_cMD_Merge_Outputs_And_Graph.R script to merge individual outputs into a single dataframe to then graph the prevalence results. The .RData generated throughout the running of this script are provided as cMD_Merge_Outputs_And_Graph.RData</p>
<p>Dependencies for each R script are provided at the start of each script. To reproduce the analysis, file paths must be changed.</p>

Land and freshwater molluscs of mainland Ecuador: an illustrated checklist
No full textThis comprehensive checklist of non-marine molluscs from the mainland of Ecuador presents data on 331 species (of which 5 are considered as nomen dubium), compiled from the literature, a subset of museum databases, and some verified observations from the internet. For all taxa the original reference is given and photographs of type specimens are provided if these could be located and obtained from museums. Where these were not available the original figure(s) have been reproduced. In the introduction, a brief history of research in Ecuador (including the Galápagos archipelago) is presented. This checklist may serve as a baseline document for further research. It is not intended to be a revisionary work, although we have recognised the following new synonyms: Neritina intermedia (var. β) minima K. Miller, 1879 = Clypeolum latissimum (Broderip, 1833); Aperostoma (Aperostoma) olivaceum Bartsch & Morrison, 1942 = Incidostoma quitense (L. Pfeiffer, 1852); Hemisinus pazi Tryon, 1866 = Hemisinus guayaquilensis (Petit de la Saussaye, 1853); Bulimus cuneus L. Pfeiffer, 1854 = Protobeliscus fairmaireanus (Petit de la Saussaye, 1853); Synapterpes (Zoniferella) riveti Germain, 1907 = Mesembrinus vesperus Jousseaume, 1887 = Zoniferella albobalteata (Dunker, 1882); Synapterpes bicingulatus Fulton, 1908 = Zoniferella bizonalis (Germain, 1907); Thaumastus thompsonoides Oberwimmer, 1931 = Kara thompsonii (L. Pfeiffer, 1845). The need for further field work is illustrated by the fact that for 60 species, only imprecise localities are known, while for 168 species no modern (i.e. last 50 years) records are available. There are 178 species considered as endemics for the Ecuadorian malacofauna. For both the terrestrial and freshwater species the ecoregions where they occur are indicated where possible
