“…However, we find that macrophyte effects were observable solely on richness difference patterns and not on species replacement patterns, which could not be attributed to any of the measured environmental variables. These results are consistent with the fact that macrophytes have often been considered a structural component of aquatic ecosystems, affecting habitat complexity (Thomaz and da Cunha 2010, Kovalenko et al 2011, Bolduc et al 2016, allowing for the establishment of a more diverse community, rather than representing an environmental filter or gradient with the potential to affect species replacement. Overall, while the measured environmental variables may enable prediction of richness differences, they are unable to determine which taxa actually fill these spots.…”

Abstract. Waterbodies in urban environments are usually built or maintained to serve socioeconomic functions. However, they also represent ecosystems that can contribute notably to urban biodiversity. To better understand contribution to biodiversity of urban ecosystems, the variation in zooplankton community composition in 19 waterbodies across the Island of Montr eal (Qu ebec, Canada) was monitored across three summer months. Communities were dissimilar between and within waterbodies with species richness differences and replacement patterns playing equal parts in shaping the observed variation. Within each waterbody, notable differences were detected between months, which can affect biodiversity estimation or community composition assessment. Zooplankton species richness was especially well explained by macrophyte cover, which had a positive effect. Compositional differences were also explained by macrophyte cover and by waterbody emptying. Partitioning the beta diversity revealed that only richness difference patterns were explained by macrophyte cover, as species replacement patterns were not explained by any of the measured environmental variables.

“…Indeed, macrophyte patches create spawning and rearing habitats and serve as a source of diversified food for fish populations (Thomaz, Dibble, Evangelista, Higuti, & Bini, 2008), wintering waterbirds (Schmieder, Werner, & Bauer, 2006), and also provide protection from predators (Grenouillet, Pont, & Olivier, 2001;Katayama, 2014). The presence of macrophytes fosters aquatic invertebrates and zooplankton richness and biomass (Bolduc, Bertolo, & Pinel-Alloul, 2016;Rennie & Jackson, 2005). Submerged aquatic vegetation, however, may also markedly reduce water velocities (Boudreau, Leclerc, & Fortin, 1994;Marjoribanks, Hardy, Lane, & Parsons, 2014;Marjoribanks, Hardy, Lane, & Tancock, 2017;Morin, Leclerc, Secretan, & Boudreau, 2000;Morin et al, 2003), which in turn can influence major biogeochemical cycles (Bal et al, 2013).…”

A three‐dimensional numerical model investigation of the impact of submerged macrophytes on flow dynamics in a large fluvial lake

Aquatic plants (macrophytes) are known to affect flow dynamics, contributing to flow resistance. Most studies on flow‐vegetation interactions are performed in laboratory flumes and focus on the flow field around plants, with little research at the level of vegetation patches in large aquatic ecosystems. In most hydrodynamic models, increased drag due to plants is modelled by increasing the Manning's n roughness coefficient. The objectives of this study were to: (1) develop a three‐dimensional hydrodynamic model (Delft3D) applicable to large water bodies including a novel approach to represent macrophyte resistance (modified k‐ε turbulence closure model); and (2) compare the modelled flow with field measurements for different vegetation configurations and patch arrangements. Work was carried out in Lake Saint‐Pierre, a large fluvial lake of the St Lawrence River in Québec, Canada. Results showed a marked increase in residence time in the zone affected by macrophytes when using the modified k‐ε turbulence closure model compared to the Manning's n approach, particularly near the bed. An improved agreement with field measured depth‐averaged velocity is obtained with this novel approach (correlation coefficient of 0.80 compared to 0.46 with Manning's n only). In addition, a good fit was obtained between vertical velocity profiles modelled and measured in the macrophyte zone. Sensitivity analysis revealed that the additional drag due to plants was closely associated with plant height, but that plant density played only a minor role in retarding velocities. These findings indicate that it is possible to accurately quantify both the horizontal and vertical flow modulations resulting from submerged vegetation in large fluvial systems. Considering that the Delft3D model is capable of approximating measured velocity magnitude, preserving the logarithmic shape throughout the water column and reaching near‐zero velocities without increasing the roughness coefficient, we recommend this modelling approach for future research on the impact of macrophytes on flow at the scale of vegetation patches in large water bodies comparable to Lake Saint‐Pierre.

“…Большой объем погруженной части макрофита формирует высокую гетерогенность водной среды, которая является ключевым фактором массового развития зоопланктона в зарослях. Ряд авторов также отмечают, что наибольшего развития в погруженных макрофитах достигают именно ветвистоусые ракообразные (Stefanidis, Parastergiadou, 2010;Bolduc et al, 2016;Курбатова и др., 2017), которые обеспечивают высокие значения биомассы зоопланктона.…”

Зоопланктоценозы малых рек изучены слабее, чем озер. В связи с этим актуальным является изучение видовой структуры сообществ зоопланктона в зарослях макрофитов малых рек. В работе дана характеристика видовой структуры и количественного развития сообществ зоопланктона медиальной зоны и зарослей высшей водной растительности малой реки Сережа Нижегородской области. На основе иерархической кластеризации в медиальной зоне реки выделены два сообщества зоопланктона-речного участка и переходного участка. Показаны отличия видовой структуры сообществ зоопланктона разнотипных зарослей макрофитов и медиальной зоны реки. Установлено, что в зарослях высшей водной растительности формируется высокое видовое богатство и количественное развитие сообществ зоопланктона. В разнотипных по морфологическому строению зарослях макрофитов установлены различия в количественном развитии и соотношении таксономических групп зоопланктона по численности и биомассе. Показано, что наибольшее влияние на зарослевый зоопланктон оказывает архитектоника макрофита и густота зарослей. В густых зарослях погруженных растений отмечены максимальные значения численности и биомассы зоопланктона. По результатам анализа избыточности показано влияние абиотических и биотических факторов среды на видовую структуру сообществ зоопланктона медиали и рипали реки. В медиальной зоне реки значительное влияние на видовую структуру сообществ зоопланктона оказывали скорость течения и рН воды, в прибрежье-проективное покрытие растений. © Петрозаводский государственный университет Получена: 21 марта 2019 года Подписана к печати: 01 октября 2019 года гаВрилко дмитрий евгеньевич ФГАОУ ВО "Национальный исследовательский Нижегородский государственный университет им.
