“…The complementary nestedness component accounted for 23% of total β diversity for macrophytes whereas it was found extremely low for fish (β Nes < 0.1). The preponderance of the turnover component over the nestedness component has already been highlighted in previous studies [33,88,89].…”

“…In this study, we performed GLMs and GDMs to identify if there is congruence between αand β-diversity (and its components) for two biotic groups (macrophytes and fish) in sixteen natural lakes of the unexplored biodiversity hotspot of the Southern Balkan Peninsula. Previous studies in the freshwater realm have reported contrasting results on the relationships between diversity and environment for different biota [32,33]. However, there is no previous study in the area, comparing the beta diversity patterns of multiple biota based on a common spatial scale and identical statistical analysis.…”

“…Diversity-based research has long focused on terrestrial vertebrates and vascular plants, with studies on freshwater ecosystems being limited [27]. Few attempts have been made to investigate the effects of both space and environment on taxonomic richness and composition variation of diverse freshwater biota with varying dispersal traits [28][29][30][31][32][33], despite the fact that lacustrine habitats are analogous to terrestrial ones, often conceptualized as habitat islands [34].…”

Disentangling the main drivers of species richness and community composition is a central theme in ecology. Freshwater biodiversity patterns have been poorly explored; yet, it has been shown that different freshwater biota have different, often contrasting responses to environmental gradients. In this study, we investigated the relative contribution of geographical and environmental (habitat-, climate- and water quality-related) factors/gradients in shaping the α- and β-diversity patterns of macrophytes and fish in sixteen natural freshwater lakes of an unexplored Balkan biodiversity hotspot, the Southern Balkan Peninsula. We employed generalized linear modeling to identify drivers of α-diversity, and generalized dissimilarity modeling to explore commonalities and dissimilarities of among-biota β-diversity. Species richness of both biota was significantly associated with lake surface area, whereas macrophytes had an inverse response to altitude, compared to fish. Both species turnover and nestedness significantly contributed to the total β-diversity of macrophytes. In contrast, species turnover was the most significant contributor to the total fish β-diversity. We found that the compositional variation of macrophytes is primarily limited by dispersal and ultimately shaped by environmental drivers, resulting in spatially structured assemblages. Fish communities were primarily shaped by altitude, highlighting the role of species sorting. We conclude that among-biota diversity patterns are shaped by different/contrasting factors, and, thus, effective/sustainable conservation strategies should encompass multiple aquatic biota.

“…Brich relates to species loss–gain or richness difference and refers to the difference in species number between sites. This method has been widely used and proven to be accurate in describing the patterns of beta diversity along ecological gradients (Heino et al ., 2019; Johansson et al ., 2019; Lansac‐Tôha et al ., 2019; Lindholm et al ., 2020). An alternative approach would be to decompose total beta diversity into turnover and nestedness components (Baselga, 2010).…”

1. Freshwater habitats are among the most threatened and least studied habitats in arid regions of Iran. Discovering factors responsible for the spatial variation of biodiversity are one of the main considerations in conservation biology. As a first step towards developing conservation strategies, we aimed to investigate the beta diversity and response of Odonata assemblages to climate and landscape variables in arid and semi-arid regions of Iran. 2. A total of 120 water bodies were surveyed. The beta diversity distance matrices were calculated for Odonata, Anisoptera, and Zygoptera, using the Jaccard dissimilarity coefficient. Also, the replacement and richness difference components of Odonata beta diversity were computed. Each of the five dissimilarity matrices was modelled by generalised dissimilarity modelling (GDM). 3. We recorded 58 species of Odonata that represent 58% of the Odonata species in Iran. The average total beta diversity was high (0.873). GDMs results showed that the most influential variables varied between the replacement and richness difference components of Odonata beta diversity as well as between the two Odonata suborders. Anisoptera were most strongly affected by the temperature annual range, while the most important variable for Zygoptera was the average wind speed in April. 4. Our results suggest that the studies of the drivers of biodiversity patterns benefit from beta diversity partitioning also from comparing species groups with different ecological preferences. The high biodiversity of the studied water bodies as well as the anthropogenic and climate threats that they are faced with, make these ecosystems a conservation priority.

“…Frota et al 2016, Froehlich et al 2017, Cavalli et al 2018, Ota et al 2018, Jarduli et al 2020. The Paranapanema River, a major tributary of the upper Paraná River, is currently fragmented by several hydroelectric dams (Britto & Carvalho 2006), and therefore, its dam-free tributaries are of great importance for the maintenance of fish species (Hoffmann et al 2005, Silva et al 2017, Galindo et al 2019, Lansac-Tôha et al 2019. Besides, the Cinzas River is an important tributary of the Paranapanema River basin, which is the main watercourse of the region known as "Norte Pioneiro" (Pioneer North) of the Paraná state, and it is essential for maintaining ichthyofauna biodiversity of the Capivara reservoir (Vianna & Nogueira 2008, Orsi 2010.…”

This work is the most comprehensive survey of the Laranjinha River´s fishes, a tributary of the Cinzas River, Paranapanema River basin. Throughout its course, there is only a low-height dam, including a transposition system located 98 km from its mouth. The sampling was carried out in nine locations, from the source to the mouth, with six field incursions in each location, using different fishing gear. A total of 11,924 fish were collected, distributed in seven orders, 27 families, and 100 species. The most representative order in the number of species was Siluriformes, followed by Characiformes. As for the families, Loricariidae comprised 21% and Characidae 14% of species richness. Phalloceros harpagos was the species with the highest absolute abundance, representing 11.3% of the total, followed by Hypostomus ancistroides with 9.8%. However, considering the average abundance and frequency of occurrence, Hypostomus ancistroides was the most abundant species, followed by Hypostomus cf. paulinus, Psalidodon aff. paranae and Phalloceros harpagos. Among the collected species, the Apteronotus acidops, Brycon orbygnianus, Brycon nattereri, Crenicichla jupiaensis, and Rhinelepis aspera were classified as endangered on the most recent IUCN Red List. Also, from the total sampled fish, 9.8% are considered non-native species. Among the native species recorded, 10 species are large migratory species, which indicates that the Laranjinha River is a route for spawning and maintenance of species diversity in the middle Paranapanema River. Therefore, the Laranjinha River is a heritage of fish diversity and deserves special attention in its preservation.
