Die Pauschalzustimmung und die Pauschalverweigerung bei der Übertragung vinkulierter Anteile
Authors: Rumpf Larissa
Published: April 2022

The present work is devoted to the discourse, which has so far been scarce in the academic literature, as to whether blanket consent to the transfer of restricted shares in a company can be granted in corporations and partnerships and whether, in mirror image, blanket refusal to transfer shares is permissible. The thesis concludes that a distinction must be made between the effectiveness and the permissibility of blanket consent, whereby the differences in the individual legal forms are discussed. In the third part of the thesis, the blanket refusal to transfer shares is examined in particular in the context of constitutional and European law. Possible claims for damages by shareholders in the event of a violation of their membership rights are also presented.

Published: April 2022

Sweetpotato [sweet potato; Ipomoea batatas (L.) Lam.] is the seventh most valued food crop of the world. It has an inherent ability to grow under diverse agro-ecological and microclimatic zones ranging from tropical and subtropical zones to temperate areas with its tuberous roots enriched with the secondary metabolites of immense nutritional value. Among these, carotenoids are the most conspicuous one for having their use in nutritional, pharmaceutical, food, feed, aquaculture, and cosmetic industries. In food industries, carotenoids are used as food additives being antioxidants with attractive colors. Despite the immense economic importance, sweetpotato has received lesser attention in terms of its breeding with improved varieties. The conventional method of breeding by crossing has not been much successful due to the complexity of genome sterility and cross-incompatibility. Hence, the modern molecular breeding approaches, e.g. genetic, genomic, and metabolic (pathway) engineering, have been applied to this crop by some of researchers in Japan, Korea, and China to generate various cultivars with improved quantities and qualities of carotenoids. This has also opened a new gate for molecular breeders to engineer new sweetpotato cultivars enriched with carotenoids under current global scenario of dramatically rising climatic changes where novel food resources are bitterly needed, especially under alarmingly growing world population, the majority of which suffers from malnutrition.

Published: April 2022

Fatty acids are molecules with important physiological functions, proved to be good bioindicators of the presence of natural and chemical stressors and so used as early warning signals. Indeed, biochemical analyzes, such as fatty acids, are an important tool in water body management and water quality analysis, allowing detecting molecular changes in aquatic communities, related to the trophic status of the systems, before they are perceived in the environment. In this work was investigated the fatty acid composition on zooplankton community collected in four reservoirs of hydroelectric plants on the Iguaçu River, Brazil, and assessed the species distribution to assess and compare the water quality in these reservoirs. Results showed the trophic state index presented a wide variation among samples, ranging from oligotrophic (Salto Caxias) to hypereutrophic (Foz do Areia). The most abundant fatty acid was docosahexaenoic acid (DHA, C22:6n3) an essential fatty acid with health benefits, playing a pivotal role in biological functions. This study highlights the sensitiveness of the zooplankton community to environmental conditions and underlines the role of fatty acids as good bioindicators, being good endpoints to use in ecological studies. This supports the zooplankton contribution as a biological quality element in the assessment of reservoir quality elements.
A New Insight of Phycoremdiation Study: Using Filamentous Algae for the Treatment of Tertiary Municipal Wastewater
Authors: Li Yan , Wood Ethan , Kosa Gergely , Muzamil Bushra , Vogelsang Christian , Holmstad Rune
Published: April 2022

This book chapter demonstrated that the filamentous algae could be used as a promising phycoremediation approach to purify municipal tertiary wastewater. Initial screening of 25 algae strains across multiple genera revealed that Spirogyra sp. and Klebsormidium sp. were suitable to treat the tertiary effluent from a modern wastewater treatment plant (WWTP), and their co-culture was validated in three consecutive outdoor pilot tests. In the first two pilot tests, the nutrient concentrations of phosphorous and ammonium were depleted close to zero within 24 hours, whereas the pH value increased from 7 to 9 in the wastewater. Therefore, CO2 was added for pH control in the 3rd batch, but the nutrient removal efficacy indicated that fresh algae inoculum was critical to maintain treatment efficiency. The biomass accumulated notable amounts of Ca, Mg, K, Fe, Al, and heavy metals from the effluent, while the algae production increased by two to three times over 7 days with an average algae biomass productivity of 1.68 g m2 d−1. The derived biomass can be used for biogas production and biofertilizer applications based on the biochemical constituent. Given a great potential for further optimization and improvement, we provide a new insight to use phycoremediation approach to facilitate the green transition of wastewater treatment plants.

Authors: Ostoich Peter , Beltcheva Michaela , Antonio Heredia Rojas Jose , Metcheva Roumiana
Published: April 2022

Radionuclide contamination poses serious hazards for terrestrial ecosystems. Beyond the readily apparent damage to the biota at high doses, low doses of ionizing radiation produce stochastic effects: mutation, carcinogenesis, and genomic instability. The proposed chapter is a review of the biological and ecological effects of radionuclides. The authors discuss, beyond the Chernobyl accident, other contamination events. The review includes the biological and ecological effects of the three principal technogenic contaminants in terrestrial ecosystems: Cs-137, Sr-90, and I-131. Ecological risks to terrestrial small mammals are assessed in detail. In addition, the chapter provides some of the lesser-known methods of remediation and detoxification, including the use of modified natural zeolites as environmental remedies and bio-sorbents. Presented herein is little-known information on environmental protection against radioactive contamination.
A New Approach to Solve Non-Fourier Heat Equation via Empirical Methods Combined with the Integral Transform Technique in Finite Domains
Authors: N. Mihăilescu Cristian , Oane Mihai , Mihăilescu Natalia , Ristoscu Carmen , Arif Mahmood Muhammad , N. Mihăilescu Ion
Published: April 2022

This chapter deals with the validity/limits of the integral transform technique on finite domains. The integral transform technique based upon eigenvalues and eigenfunctions can serve as an appropriate tool for solving the Fourier heat equation, in the case of both laser and electron beam processing. The crux of the method consists in the fact that the solutions by mentioned technique demonstrate strong convergence after the 10 eigenvalues iterations, only. Nevertheless, the method meets with difficulties to extend to the case of non-Fourier equations. A solution is however possible, but it is bulky with a weak convergence and requires the use of extra-boundary conditions. To surpass this difficulty, a new mix approach is proposed with this chapter resorting to experimental data, in order to support a more appropriate solution. The proposed method opens in our opinion a beneficial prospective for either laser or electron beam processing.
Immunology of Helicobacter pylori Infection
Authors: Darmadi Darmadi , Habriel Ruslie Riska
Published: April 2022

Helicobacter pylori (H. pylori) is the most common infecting microorganism in humans. H. pylori had coexisted with humans for 30,000 years ago and developed extensive survival adaptations. The infection is both active and chronic and leads to several disorders from chronic gastritis to gastric adenocarcinoma. The prevalence of H. pylori infection is still high in developing countries. The burden of disease due to infection is also heavy. The persistence of infection is the basis of diseases. H. infection activates innate and adaptive immune responses but the immune response fails to eradicate the infection. H. pylori is able to evade both innate and adaptive immune responses. It can neutralize gastric acid, elicit autoimmunity toward parietal cells, prevent phagocytosis, induce apoptosis of immune cells, inhibit lymphocyte proliferation, disrupt imbalance between humoral and cellular adaptive immune responses, promote regulatory T cell activity, and trigger genetic rearrangement. Host factor is involved in the incidence of H. pylori infection and its complications. Reinfection after eradication is common. Multiple drug resistance has also emerged. Vaccination is a promising management approach to eradicate H. pylori and prevent diseases it caused. The development of the vaccine itself needs to consider the immune escape mechanism of H. pylori.

A History of the Fenton Reactions (Fenton Chemistry for Beginners)
Authors: Ovalle Rafael
Published: April 2022

A deceptively simple mixture, ferrous sulfate (FeSO4), hydrogen peroxide (H2O2), tartaric acid (C4H6O6), and water (H2O), initiated a century-long argument and a convoluted hunt to understand the oxidation mechanism(s) initiated by the combination of these components. Fenton’s discovery rallied a legion of scientists, including two Nobel Winners, to find an explanation for the chemistry discovered when a graduate student mixed a couple of random chemicals, producing a molecule that became purple in strong base. Those investigation uncovered three separate branches of iron/oxygen chemistry, the Hydroxyl Radical [HO•], the Ferryl-Oxo Ion [Fe = O]+2, and the Perferryl-Oxo Ion [Fe = O]+3. Today their uses include chemical modifications [either untargeted and random [HO•] or targeted and selective [Fe = O]+2, [Fe = O]+3 dehydrogenations and/or oxygen additions] to effective and green oxidation and mineralization of persistent organic wastes.
Paul Ricoeur and Fratelli tutti: Neighbor, People, Institution
Authors: Daughton Amy ,   Villanova University
Published: April 2022

Unusually, Fratelli tutti and Laudato si’ both cite the work of French thinker Paul Ricoeur. It is unusual because reference to individual scholars can be rare in Catholic social teaching, and because Ricoeur was a philosopher, and not a Catholic. Yet Ricoeur’s work, which spanned nearly seventy years and incorporated both philosophy and engagement with religious resources, focused on meaningful communication in text and action for the work of living together. For an encyclical committed to rethinking and rejuvenating attitudes to each other in public life, across disagreement, Ricoeur’s work provides an ideal conversation partner. His approach involves attending carefully to the ethical entanglement of self and other, mediated by the institution. This attention supports the driving concern and reasoning of Fratelli tutti—to recenter the agency of neighbor, people, and institution for the fragile political work of deliberation, cooperation, and action.

Deep Music Information Dynamics Novel Framework for Reduced Neural-Network Music Representation with Applications to Midi and Audio Analysis and Improvisation
Authors: Dubnov Shlomo , Chen Ke , Huang Kevin
Published: April 2022

Generative musical models often comprise of multiple levels of structure, presuming that the process of composition moves between background to foreground, or between generating musical surface and some deeper and reduced representation that governs hidden or latent dimensions of music.  In this paper we are using a recently proposed framework called Deep Musical Information Dynamics (DMID) to explore information contents of deep neural models of music through rate reduction of latent representation streams, which is contrasted with hight rate information dynamics of the musical surface. This approach is partially motivated by rate-distortion theories of human cognition, providing a framework for exploring possible relations between imaginary anticipations existing in the listener's or composer's mind, and the information dynamics of the sensory (acoustic) or symbolic score data. In the paper the DMID framework is demonstrated using several experiments with symbolic (MIDI) and acoustic (spectral) music representations. We use variational encoding to learn a latent representation of the musical surface. This embedding is further reduced using a bit-allocation method into a second stream of low bit-rate encoding. The combined loss includes temporal information in terms of predictive properties for each encoding stream, and accuracy loss measured in terms of mutual information between the encoding at low rate and the high rate surface representations. For the case of counterpoint, we also study the mutual information between two voices in a musical piece at different levels of information reduction.The DMID framework allows to explore aspects of computational creativity in terms of juxtaposition of latent/imaginary surprisal aspects of deeper structure with music surprisal on the surface level, done in a manner that is quantifiable and computationally tractable. The relevant information theory modeling and analysis methods are discussed in the paper, suggesting that a trade off between compression and prediction play an important factor in the analysis and design of creative musical systems.

Authors: Vajgand Dragan
Published: April 2022

The number of adults was monitored using a light trap type RO Agrobečej at the localities of Sombor and Begeč during 2020 and 2021. In this paper, analyzed was the correlation between that appearance frequency and the Degree day - (DD). Adults were trapped throughout the trap season from April 11th to October 19th. Altogether, five frequency peaks were recorded from June to October. Recorded peaks corresponded to DD values of 245, 457, 593, 660 and 787, respectively. The highest peak corresponded to DD value of 593. In order to get a broader picture of the appearance, DD were also calculated for 2017, 2018 and 2019. For DD 200, the mean occurrence was calculated Jun 12th, DD 245 June 18th, DD 457 July 12th , DD 593 July 28th, DD 660 August 11th and DD 787 August 17th. The distance from the mean occurrence of DD 200 on June 12th to the maximum occurrence of DD 593 on July 28th is 46 days, with a difference of DD 393. DD values from March 30th (biofix) to October 20th ranged from 951 to 1245.

Authors: Gajić-Umiljendić Jelena , Sarić-Krsmanović Marija , Radivojević Ljiljana , Šantrić Ljiljana
Published: April 2022

In laboratory conditions 10 actinobacteria strains were screened for germination and seedling growth of maize and Johnson grass. Primary inoculum of actiobacteria were grown in starch casein broth for 7 days in a shaking incubator. Ten seeds from both species, were placed inside sterile Petri dishes and moinsted with 5ml of the culture filtrate of actinobacteria and incubated at 26°C. After the period of 7 days, the percentage of germination was calculated and coleoptile and radicle length were measured. Suspensions of all 10 actinobacteria strains had an effect on seed germination and early seedling growth of maize and Johnson grass. The A18 strain proved to be the best candidate for further testing because the inhibitions for maize were less than 35% and for Johnson grass they were higher than 90%.

Severe acne treatment
Authors: Jovanović Dragan
Published: April 2022

Acne vulgaris are one of the most common diseases of puberty and early adolescence. It is a dermatosis of polymorphic clinical manifestation. The course of the disease is chronic. In a small number of patients, the changes may persist throughout the third decade of life, and even - longer. A variety of changes can be observed in patients with acne. There are non-inflammatory and inflammatory forms of acne. Non-inflammatory forms are characterized by the presence of comedones (acne comedonica), while inflammatory papules, pustules, induced changes, nodules, cysts, abscesses, fistulas are observed. The finding of pustular, and especially nodular changes is prognostically less favorable because the evolution of changes in severe and moderate forms of the disease can end in form of scars. These scars can be hypertrophic (keloid) or atrophic. Also, as a consequence of inflammatory changes, there may be post-inflammatory pigmentation. The number and type of changes in the same patient may differ in different periods. Acne treatment is very complex and requires an individual approach to each patient. It is long-lasting and requires persistence and patience, especially by the patient. Treatment, depending on the severity of the changes, may involve the application of local, physical or systemic therapy. Acne vulgaris are a significant medical and aesthetic problem, and the role of dermatologists is an absolute priority.
Bulimia: Modern man challenge
Authors: Đurović Marija
Published: April 2022

The fact, that man has always been focused on external beauty is never surprising. The base of our identity is our body. However, it is worrying to know that whether they are obese, thin, or normally fed, people of both sexes and all age groups have never been as dissatisfied with their bodies as they are today. Many do not perceive eating disorders as serious diseases, but as someone's whim, the desire to be thin, and some even go so far as to accept a disturbed diet as healthy. We notice that healthy people talk about eating disorders in an affirmative tone - they don't understand that it is a disease. Avoiding a normal diet is considered "normal" and even desirable. Unfortunately, eating disorders are culturally normalized. The most commonly diagnosed eating disorders are anorexia nervosa and bulimia nervosa. Unlike anorexia nervosa, bulimia nervosa is much more difficult to detect. It can remain unrecognized for a long time even from the immediate environment, because a person suffering from bulimia is usually of normal body weight, and bulimic crises usually take place in secret. And then, even when the disease is discovered, its meaning and severity are often unrecognized. Unfortunately, bulimia nervosa is often experienced as a whim of a spoiled child from a rich society. In etiological terms, bulimia nervosa is a multifactorial disease. In its origin and development, the role is played by various factors that interact with each other: genetic, neurobiological, psychological and socio-cultural. There are many interpretations of the psychodynamics of bulimia nervosa, the significance and symbolism of symptoms. The most common comorbidities are depression, anxiety disorders, PTSD, and substance abuse. The consequences of the disease are in the sphere of mental and physical health. Recognition and treatment of bulimia nervosa is extremely important, and psychotherapy and pharmacotherapy are used in the treatment of patients.

Published: April 2022

Atrial fibrillation (AF) is a complex disease associated with an increased risk of stroke, heart failure, repeated hospitalizations and reduced quality of life, as well as increased mortality. The treatment of AF is complex and requires the involvement of both, the doctor and the entire health system, as well as the patient himself. All international associations of cardiologists periodically publish guidelines for the diagnosis and treatment of AF that are in line with the latest scientific evidence. The latest guidelines of the European Society of Cardiology (ESC) for the treatment and diagnosis of AF, published in 2020, have formulated a diagram of diagnosis and treatment of AF with the aim of facilitating timely diagnosis of AF and optimal treatment of patients with this arrhythmia. The diagram includes diagnostic confirmation that it is AF, structured characterization of patients with AF (4S-AF scheme) and ABC algorithm that includes anticoagulant therapy to prevent thromboembolic complications of AF, better control of symptoms (control of heart rate and / or ventricular rate) as well as detection and treatment of comorbidities and cardiovascular risk factors and correction of harmful life habits. To make it easier to remember the key components of the diagnosis and treatment of AF, the diagram is summarized in the abbreviation CC To ABC, according to English names. The aim of this paper is to present the key messages of the latest ESC guidelines for AF treatment and diagnosis.

FAULT DETECTION BASED ON THE DISCRETE WAVELET TRANSFORM FOR THE CONVERTER OF A WIND POWER GENERATOR SYSTEM OPERATING UNDER DISTURBANCES IN THE GRID
Authors: DE LA ROSA  MENDOZA SAN JOSE , ALVAREZ SALAS RICARDO , González García Mario , CARDENAS GALINDO VICTOR MANUEL , VILLALOBOS PIÑA FRANCISCO J. , MIRANDA VIDALES HOMERO
Published: April 2022

In this work, an open-circuit fault detection scheme for the converter of a wind power generation system is proposed and evaluated, which is robust to false detections under grid disturbance conditions such as sags and swells. The wind energy system is composed of a doubly-fed induction generator (DFIG) that supplies energy to the electrical grid through a power electronics converter based on the neutral point-clamped topology in a back-to-back configuration (NPC-BTB).
The converter operates with a field-oriented-control (FOC) scheme, whereas the fault detection method is based on the processing of the current signals flowing through the converter at the rotor and stator sides of the generator using the discrete wavelet transform (DWT) with the Haar and Daubechies4 wavelet types. The fault detection scheme is evaluated verifying that false detections do not arise, analyzing cases where magnitude variations in the grid voltage of 15%, 30% and 50% occur, with respect to the nominal operating condition.
Depth, Significance, and Absence
Authors: Moore Bridie
Published: April 2022

In view of Judith Butler’s assertion that identity as an effect is generated by “cultural apparatus” (Gender Trouble 199), this article interrogates the age-ef- fects generated by early twenty-first century mainstream British theatre. To ana- lyze the complex ways in which age is played out on the British stage—which seem at once both to challenge and to reiterate long-standing assumptions about age—it examines five productions seen in the autumn/winter season of 2011/12. It considers to what extent these productions disrupt the generation of normative age-effects and explores the often contradictory consideration of age in the “multiple realities of performance” (Lipscomb “The Play’s the Thing” 117). This exploration enlists the theories of Butler and others, including Anne Basting, who proposes a model of performance that enacts the body in its “temporal depth” (Stages of Age 22); Anca Cristofovici, who offers a conceptu- alization of the aged body as “significant form” (“Touching Surfaces” 275); and Kathleen Woodward, who ponders the psychic crisis resulting from a rejected, and therefore absent, reflection of the aging body (Aging and its Discontents 53–71). Viewing the staging of age through the lenses of “depth,” “signifi- cance,” and “absence” exposes the meanings of specific age performances and uncovers the age-effects of a theatre responding to the changing context of an aging Britain.
The Literacy Narrative of Chadwick’s The First Grader
Authors: Marshall Bowen Lauren
Published: April 2022

While examination of narratives written by and about older adults is, by now, recognized as crucial to the critical work of age studies, the overlapping proj- ects of age studies and studies of literate activity (including writing) have not yet been sufficiently integrated. Through analysis of The First Grader, a film dramatizing the true story of an eighty-four-year-old Kenyan man who attends primary school in order to learn how to read and write, this essay illustrates the value in establishing deliberate cross-talk between age studies and writing studies through joint examination of literacy narratives: stories that capture both master and “little” narratives about literacy and learning. As a cinematic literacy narrative featuring an elder protagonist, The First Grader demonstrates how age meanings and age identities impact and challenge culturally endorsed perceptions of literacy and learning by uncritically representing prefigured ideas about literacy and old age, while also suggesting some critical alterna- tives. At the same time, the film acknowledges how literacy and learning contribute to, and are implicated by, the creation and circulation of the meanings of old age.

AbstractDuring the period 2018 to 2020, we followed 60 victims of crime and interviewed them at various stages of the judicial process from their first meeting with police until the conclusion of their cases. In this article, we analyze our interviews using Arnold Van Gennep’s and Victor W. Turner’s theoretical frameworks on rites de passage and social drama. Our analysis demonstrates how these theories are helpful in unravelling and deepening our understanding of victims’ experiences with the justice system.
Mistenksomhetens spiral

Published: April 2022

AbstractIn March and April 2020, at the earliest stages of the COVID-19 pandemic, the Norwegian government prohibited overnight stays at secondary homes as an early measure to prevent the spread of the virus. Violations of the ban carried penalties of up to 6 months in prison. Popularly dubbed the Cabin Ban, the law catalysed national debate, and violations of the ban generated massive public interest. This article recounts local conflicts sparked by the ban in four Norwegian «cabin municipalities», as described by residents, local politicians and cabin owners. It identifies the notion of autochthony as a central tool in  understanding why some chose to breach the ban, why local residents mobilised against cabin owners, and why the conflict escalated to the extent it did.

In-plane heat dissipation technology based on flexible thermoelectric film cooling is expected to provide a solution to efficient in-plane heat dissipation of electronic devices. However, the low electrical transport performance of flexible thermoelectric films and the difficulty in designing the structure of in-plane heat dissipation device seriously restrict the applications of this technology in heat dissipation of electronic devices. In this work, an epoxy/Bi0.5Sb1.5Te3 flexible thermoelectric film is incorporated with graphene which can simultaneously regulate the electrical and thermal transport behaviors. It is found that the incorporating of graphene not only contributes to the preferential orientation of Bi0.5Sb1.5Te3 grains along (000l), but also provides a fast carrier transport channel. The carrier concentration and mobility of graphene/Bi0.5Sb1.5Te3 flexible thermoelectric film are simultaneously increased. Comparing with the epoxy/Bi0.5Sb1.5Te3 flexible thermoelectric film, the highest power factor of the flexible thermoelectric film with 1.0% graphene at room temperature reaches 1.56 mW/(K2·m), increased by 71%, while the cooling temperature difference is doubled. Using this high-performance graphene/Bi0.5Sb1.5Te3 flexible thermoelectric film cooling, a cascade structure high-efficiency in-plane heat dissipation device is designed and fabricated. The device can dissipate heat from the heat source area to the heat dissipation area step by step and reduce the temperature of the heat source area by 1.4–1.9 ℃, showing an efficient and stable in-plane heat dissipation capability.

Doublecortin (DCX) is a microtubule (MT)-associated protein that regulates MT structure and function during neuronal development and mutations in DCX lead to a spectrum of neurological disorders. The structural properties of MT-bound DCX that explain these disorders are incompletely determined. Here, we describe the molecular architecture of the DCX–MT complex through an integrative modeling approach that combines data from X-ray crystallography, cryo-electron microscopy, and a high-fidelity chemical crosslinking method. We demonstrate that DCX interacts with MTs through its N-terminal domain and induces a lattice-dependent self-association involving the C-terminal structured domain and its disordered tail, in a conformation that favors an open, domain-swapped state. The networked state can accommodate multiple different attachment points on the MT lattice, all of which orient the C-terminal tails away from the lattice. As numerous disease mutations cluster in the C-terminus, and regulatory phosphorylations cluster in its tail, our study shows that lattice-driven self-assembly is an important property of DCX.
Predicting defects in imbalanced data using resampling methods: an empirical investigation
Authors: Malhotra Ruchika , Jain Juhi
Published: April 2022

The development of correct and effective software defect prediction (SDP) models is one of the utmost needs of the software industry. Statistics of many defect-related open-source data sets depict the class imbalance problem in object-oriented projects. Models trained on imbalanced data leads to inaccurate future predictions owing to biased learning and ineffective defect prediction. In addition to this large number of software metrics degrades the model performance. This study aims at (1) identification of useful metrics in the software using correlation feature selection, (2) extensive comparative analysis of 10 resampling methods to generate effective machine learning models for imbalanced data, (3) inclusion of stable performance evaluators—AUC, GMean, and Balance and (4) integration of statistical validation of results. The impact of 10 resampling methods is analyzed on selected features of 12 object-oriented Apache datasets using 15 machine learning techniques. The performances of developed models are analyzed using AUC, GMean, Balance, and sensitivity. Statistical results advocate the use of resampling methods to improve SDP. Random oversampling portrays the best predictive capability of developed defect prediction models. The study provides a guideline for identifying metrics that are influential for SDP. The performances of oversampling methods are superior to undersampling methods.
How beavers affect riverine aquatic macroinvertebrates: a review
Authors: Washko Susan , Willby Nigel , Law Alan
Published: April 2022

Background

As ecosystem engineers, the construction of dams by beavers alters stream habitat physically and biologically, making them a species of interest for habitat restoration. Beaver-created habitat changes affect a wide range of aquatic invertebrate species. However, despite numerous individual studies of how beavers affect aquatic macroinvertebrate assemblages, there has been no evaluation of the consensus of these effects across studies.

Methodology

We collated and examined studies comparing beaver-created ponds to nearby lotic reaches to determine general trends in aquatic macroinvertebrate richness, density, biomass, and functional composition between habitats. From this evidence, we highight knowledge gaps in how beaver activity affects aquatic macroinvertebrates.

Results

Overall, in the majority of studies, aquatic macroinvertebrate richness was higher in nearby lotic reaches compared to beaver-created ponds, but richness at coarser scales (gamma diversity) increased with the addition of beaver ponds due to increased habitat heterogeneity. Functional feeding group (FFG) patterns were highly context-dependent, though predator taxa were generally more abundant in beaver ponds than adjacent lotic reaches. Site-specific geomorphological changes, coupled with dam or riparian zone characteristics and resulting differences in basal food resources likely shape other FFG responses.

Conclusions

We identify a lack of long-term studies at single or multiple sites and conclude that fine-scale approaches may improve our understanding of the dynamics of macroinvertebrates within the freshwater realm and beyond. Due to the context-dependent nature of each study, further systematic studies of beaver engineering effects across a wider variety of environmental conditions and wetland types will also help inform land and species management decisions, such as where to prioritize protection of beaver habitats in the face of a global freshwater biodiversity crisis, or where to restore beaver populations to deliver maximum benefit.
