An updated checklist of species of WG mayflies is provided and sorted by traits of individual species and supplemented by personal observations. Comparisons are made in this context with patterns of current distribution of some ancient lineages of myriapods, amphibians and birds from the WG focusing on relative roles of geographical barriers (gaps), paleoclimatic, eco-evolutionary scenarios and anthropogenic impacts. This is to highlight the need to prioritize conservation of this rapidly shrinking precious biological heritage. Future work on molecular aspects of intra- and interspecific diversity of mayflies, which are “sentinels of inland water ecosystem health” should be augmented in tune with current research trends in montane “sky islands” especially from adjacent Oriental tropics.</span></span></span></span></p> K.

Mayflies have been widely used as indicators of water quality and frequently play an important role in biomonitoring protocols. Mayflies exhibit a decrease in taxa richness with increases in stream or river pollution and degradation. A series of taxonomic studies on Thai mayflies reported 19 families, 73 genera, and approximately 176 species. The families Baetidae and Heptageniidae are the most diverse and widespread groups of Thai mayflies. Our understanding of the diversity of Thai mayflies has steadily increased in recent years. New genera are being described: </span><span lang="en-GB"><em>Cymbalcloeon </em></span><span lang="en-GB">Suttinun, Gattolliat &amp; Boonsoong, 2020;</span><span lang="en-GB"><em> Elatosara</em></span><span lang="en-GB"> Malzacher, 2020;</span><span lang="en-GB"><em> Megabranchiella</em></span><span lang="en-GB"> Phlai-ngam &amp; Tungpairojwong, 2022</span><span lang="en-GB"><em>; Mekongellina</em></span><span lang="en-GB"> Malzacher, 2019; </span><span lang="en-GB"><em>Sangpradubina</em></span><span lang="en-GB"> Boonsoong &amp; Sartori, 2016; and </span><span lang="en-GB"><em>Thainis</em></span><span lang="en-GB"> Malzacher, 2020. New species and new country records are constantly being discovered in Thailand. Nevertheless, the number of genera and species seems to be lower than the species diversity estimation, and several genera and species remain undescribed. Research on the systematics and ecology of mayflies has been increasing in recent years. DNA barcoding can provide a powerful supplement to the traditional morphological approach to species delimitation. The book entitled “Mayfly Larvae in Thailand” (Thai version) and the boardgame “Thai Mayflies” were developed for environmental science communication. Further efforts are required to assess the conservation status of mayfly species. Thus, data on mayfly diversity and ecological requirements could be used as tools to evaluate environmental impacts on water resources and to drive future research on biodiversity conservation management strategies.</span></span></span></span></p> BOONSATIEN BOONSOONG Copyright (c) 2023 https://mapress.com/zs/article/view/zoosymposia.24.1.8 Mon, 31 Jul 2023 00:00:00 +1200 <strong>Ecology and phenology of stoneflies (Plecoptera) in the northern slopes of the Central Caucasus in winter and spring seasons</strong> https://mapress.com/zs/article/view/zoosymposia.24.1.9 <p align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><span lang="en-GB">The species of winter- and spring emerging plecopterans inhabiting the northern slopes of the Central Caucasus (territory of the Republic of North Ossetia-Alania, Russia) were examined.

We aim to analyze the richness and abundance patterns of mayflies in headwater streams of the Ctalamochita river basin in central Argentina, where some sub-basins have been fully afforested with exotic pines. We sampled 3 grassland streams and 3 pine afforested streams in 2008, 2012, 2014, and 2015.

As dispersal is one of the main factors driving the metacommunity structure, it is important to understand the interaction between landscape and dispersal to apply metacommunity theory. Herein, we summarize the main challenges of applying metacommunity theory to the mayfly, stonefly and caddisfly community (Ephemeroptera, Plecoptera and Trichoptera, or EPTs). Then, we attempt to solve some of the open questions regarding EPT dispersal and its relation with riparian forests. First, we investigate the diversity of functional dispersal traits of the European EPT species, analysing the existing empirical data and selecting a suitable functional index. Second, we assess the effect of riparian forest in landscape connectivity for EPTs, concluding that deciduous riparian forest can enhance dispersal. Third, we extend the study to four European regions, concluding that the role of native riparian forest as dispersal corridor differs between regions. We achieved three goals: First, we produced a theoretical and methodological framework to include dispersal in the study of EPT metacommunity, highlighting the role of riparian forest as a dispersal corridor. Second, we identify several aspects that require further investigation such as empirical dispersal studies or interactions between ecological stressors and dispersal. Third, we provide a new perspective for riverine and riparian ecosystems management, highlighting the need to consider riparian buffers as an integral part of the riverine ecosystems.</span></span></span></span></p> ANDRÉS PEREDO ARCE, JOCHEM KAIL, MARTIN SCHLETTERER Copyright (c) 2023 https://mapress.com/zs/article/view/zoosymposia.24.1.14 Mon, 31 Jul 2023 00:00:00 +1200 <strong>Systematics and updated range alter the conservation status of the Louisiana Needlefly, <em>Leuctra szczytkoi </em>Stark & Stewart, 1981 (Plecoptera: Leuctridae)</strong> https://mapress.com/zs/article/view/zoosymposia.24.1.15 <p align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><span lang="en-GB">The Louisiana Needlefly, </span><span lang="en-GB"><em>Leuctra szczytkoi</em></span><span lang="en-GB"> Stark &amp; Stewart, 1981, was one of 404 species petitioned in 2010 by the Center for Biological Diversity for inclusion and protection under the United States Endangered Species Act.

Uncertainty continued into 2022. We could not wait longer, so The Joint Meeting of the XVI International Conference on Ephemeroptera and XX International Symposium on Plecoptera was a virtual affair hosted from the University of Illinois Urbana Champaign, U.S.A. The conference occurred daily, 0600–0900 hrs Chicago time, 26–29 July 2022. Despite the virtual venue, 41 oral (video) and 26 poster presentations were given by a total of 133 authors, representing 28 countries. At least 196 unique persons attended the 12 hrs of conference. It was a surprisingly successful meeting. The meeting program and links to all presentations are available from Plecoptera Species File. There were no Lifetime Achievement Awards bestowed upon our members during this meeting. A proposal for a meeting in 2024 in Turin, Italy was presented and accepted. In the weeks following the conference, we learned of the tragic death of our good friend and colleague Dr. Boris C. Kondratieff. We dedicate this volume to his memory and provide an obituary in this volume.</span></span></span></span></p> R.

Boris was a 35 year employee of Colorado State University (CSU). He served as Director of the C. P. Gillette Museum of Arthropod Diversity, a collection of nearly 3.5 million specimens, most of which were amassed after his hire in 1986. He taught many courses at CSU and they were nearly always filled to capacity. Boris served as advisor for some 50 master’s and PhD students. He was highly sought after for graduate committees. His students conducted many high-quality research projects on the taxonomy, biogeography, and ecology of aquatic insects. In later years he collaborated with such luminaries of aquatic ecology as N. LeRoy Poff and James V. Ward, both of CSU.</span></span></span></span></p> R. EDWARD DEWALT Copyright (c) 2023 https://mapress.com/zs/article/view/zoosymposia.24.1.4 Mon, 31 Jul 2023 00:00:00 +1200
