“…Freshwater diatom assemblages are highly diverse and ubiquitous, and constitute an important proxy to estimate primary production in lakes (Hall and Smol 1999). Similarly, chironomids are an important proxy to assess secondary production in lakes (Anderson et al 2012). These two groups colonize many habitats both within the littoral zone and deep lake environments (Cao et al 2012;Laird et al 2010).…”

Until recently, the distribution of diatom and chironomid species assemblages and their attributes (e.g. species richness and diversity) in relation to water depth and sedimentary environments have been identified but not quantified. The influence of environmental variables on assemblage distribution and taxa richness in a deep, monomitic lake in São Miguel Island is assessed. Attention is given to community variation along a depth gradient. Surface-sediment diatom and chironomid assemblages were collected along three transects from shoreline to the centre deep basin of the lake at a resolution of 1 m water depth. Linear and unimodal regressions were used to test taxon richness, taxon diversity and taxon evenness versus water depth of each transept. A hump-shaped relationship between species richness and water depth was noted, with a peak occurring at mid depth levels, meaning that samples located at that depth better represented the total subfossil assemblage of lake Azul. Also, diatom and chironomid assemblages in Lake Azul, and taphomomic effects, were influenced by sedimentary environmental processes depending on the lake morphology. Based on the present results, in order to determine ideal coring locations for lake studies combining diatom and chironomid analyses, an understanding of the spatial distribution of these biota is essential.

“…With a body length ranging from 2.0 to 29.4 mm, the larva consists of an anterior head, a slender body, and a posterior proleg. [ 41,49–51 ] The complex swimming gait of larva in the horizontal plane can be divided into two stages. At the beginning of the first half stroke, the larva's body flexes to one side forming a circle‐like structure, followed by body rotation and rapid unfurling.…”

these natural modes of locomotion with engineered systems has been challenging. [11][12][13] In this respect, burgeoning effort has been devoted to developing new simulation tools, physical models, and experimental platforms. Among these engineering tools, soft robotic systems are promising in light of their biologically relevant mechanical compliance, deformability, and modes of locomotion. [4,[14][15][16][17] Untethered soft robots, which can freely move without requiring a physical connection to external hardware and power supplies, are good candidates for studying the locomotion modes of natural invertebrates. [18][19][20][21] Thanks to recent advances in fabrication methods, [22][23][24][25][26] functional materials, [27][28][29] and actuation strategies, [7,[30][31][32][33][34][35] roboticists have proposed several soft robots that are capable of mimicking some features of natural animal locomotion. For example, previous efforts with photo-responsive hydrogels-based robots demonstrated the ability to mimic peristaltic earthworm crawling. [36] Likewise, untethered soft robots powered with shape memory alloy have been shown to exhibit a variety of locomotion modes, including undulation, jumping, crawling through narrow space or walking over rough terrain. [37,38] The application of magnetic soft robots in biomimetic study has received growing attention due to their high controllability. Hu et al. developed a millimeter-scale film robot that achieves multiple locomotion modes,The efficient motility of invertebrates helps them survive under evolutionary pressures. Reconstructing the locomotion of invertebrates and decoupling the influence of individual basic motion are crucial for understanding their underlying mechanisms, which, however, generally remain a challenge due to the complexity of locomotion gaits. Herein, a magnetic soft robot to reproduce midge larva's key natural swimming gaits is developed, and the coupling effect between body curling and rotation on motility is investigated. Through the authors' systematically decoupling studies using programmed magnetic field inputs, the soft robot (named LarvaBot) experiences various coupled gaits, including biomimetic side-to-side flexures, and unveils that the optimal rotation amplitude and the synchronization of curling and rotation greatly enhance its motility. The LarvaBot achieves fast locomotion and upstream capability at the moderate Reynolds number regime. The soft robotics-based platform provides new insight to decouple complex biological locomotion, and design programmed swimming gaits for the fast locomotion of softbodied swimmers.

“…Larval Diptera in particular have high productivity and provide diverse ecological services (Adler & Courtney, 2019), including the primary support of fish communities in rivers (Benke, 1998). Chironomidae are considered critical to the support of the large population of lake sturgeon in the Lake Winnebago, WI system (Anderson et al, 2012). Chiasson et al, (1997) found an association between juvenile lake sturgeon distribution and the general macroinvertebrate community.…”

Stocking is an adaptive management tool for resource management agencies to return native fish to historic waters where they have been extirpated (Bearlin et al., 2002;Cochran-Biederman et al., 2015).Assessment of changing physical and biotic habitat conditions is critical to fisheries and environmental management projects, including the reintroduction of native species (Cooke et al., 2012;Pegasov, 2009). In most cases when managers use reintroduction as a tool for conservation of long lived animals with long generation times, the calculated timeline for nonintervention population recovery is much greater than 100 years (Auer, 2004;Vélez-Espino & Koops, 2009). In any native fish reintroduction or conservation effort, understanding feeding ecology and the adequacy of the prey base is critical for success (Amacker & Alford, 2017;Civiello et al., 2018;Garvey & Chipps, 2012). Critical assessment of habitat use includes the evaluation of the use of that prey base (Amacker &
