Plankton Communities

Structural and functional responses of plankton communities to cadmium stress were studied during 1977 in Lake Michigan using small-volume (8 L) completely sealed enclosures, and in Canada's Experimental Lakes Area (ELA) Lake 223 using large-volume (1.5 × 105 L) open-surface enclosures. In Lake Michigan, reductions of the average abundance of micro-crustaceans by cadmium were significantly greater in "light" or shallow epilimnetic incubations than they were in "dark" or deep epilimnetic incubations. Measurements of dissolved oxygen indicated that this interaction with light (depth) was an indirect effect due to a reduction of photosynthesis and primary production. Zooplankton density and species diversity were not significantly affected within 21 d by cadmium concentrations [Formula: see text] and [Formula: see text] Cd/L, respectively, whereas final dissolved oxygen concentration and percentage similarity (PS) of the crustacean zooplankton community were significantly reduced by [Formula: see text] Cd/L. In the ELA Lake 223 experiment, the reducing effect of cadmium on zooplankton density increased up to 31 d after Cd enrichment and then decreased, probably due to decreasing Cd concentrations in the water. Values of PS on day 24 for the ELA enclosures enriched with 1 and 3 μg Cd/L were within the 95% confidence limits for individual values predicted from a regression of PS on cadmium for the 21-d Lake Michigan experiments.Key words: plankton communities, zooplankton, phytoplankton, cadmium stress, Lake Michigan, Canadian Shield lakes

BACKGROUND The wide availability and small size, together with the decrease in pricing of different types of sensors, has made it possible, over the last decade, to acquire a huge amount of data about a person's life in real time. These sensors can be incorporated into personal electronic devices available at reasonable cost, such as smartphones and small wearable devices. They allow the acquisition of images, audio, location, physical activity and physiological signals, among other data. With these data, usually denoted as lifelog data, we can then analyze and understand personal experiences and behaviors. This process is called lifelogging. OBJECTIVE The goal of this article is to review the literature in the research area of lifelogging over the past decade and provide an historical overview on this research topic. To this purpose, we analyze lifelogging applications that monitor and assist people with memory problems. METHODS We follow a narrative review methodology to conduct a comprehensive search of relevant publications in Google Scholar and Scopus databases. In order to find these relevant publication, topic-related keywords were identified and combined based on different lifelogging type of data and applications. RESULTS A total of 124 publications were selected and included in this narrative review. 411 publications were retrieved and screened from the two scholar databases. Out of these, 114 publications were fully reviewed. In addition, 32 more publications were manually included based on our bibliographical knowledge in this research field. CONCLUSIONS The use of personal lifelogs can be beneficial to improve the life quality of people suffering from memory problems, such as dementia. Through the acquisition and analysis of lifelog data, lifelogging systems can create digital memories to be used as surrogate memory. Through this narrative we understand that contextual information can be extracted from the lifelogs and it provides significant information for understanding the daily life of people suffering from memory issues based on events, experiences and behaviors.

In recent years, athlete action recognition has become an important research field for showing and recognition of athlete actions. Generally speaking, movement recognition of athletes can be performed through a variety of modes, such as motion sensors, machine vision, and big data analysis. Among them, machine vision and big data analysis usually contain significant information which can be used for various purposes. Machine vision can be expressed as the recognition of the time sequence of a series of athlete actions captured through camera, so that it can intervene in the training of athletes by visual methods and approaches. Big data contains a large number of athletes’ historical training and competition data which need exploration. In-depth analysis and feature mining of big data will help coach teams to develop training plans and devise new suggestions. On the basis of the above observations, this paper proposes a novel spatiotemporal attention map convolutional network to identify athletes’ actions, and through the auxiliary analysis of big data, gives reasonable action intervention suggestions, and provides coaches and decision-making teams to formulate scientific training programs. Results of the study show the effectiveness of the proposed research.

Gîtes Larvaires

Les Culicidae, communément appelés moustiques, par leur large distribution et leur abondance, sont impliqués dans la transmission de nombreuses maladies humaines et animales. La lutte contre ces insectes nécessite la connaissance de leurs lieux de développement dans lequel évoluent les stades pré imaginaux. La présente étude vise à caractériser ces gîtes larvaires en vue d’identifier les indicateurs entomologiques et écologiques de production de larves dans ces milieux. Pour ce faire, le pH, la température, la conductivité, la teneur en oxygène dissout et la densité larvaire des culicidae ont été estimés à la suite des prospections des gîtes larvaires effectuées de juillet 2007 à mars 2018 à Saga, un quartier périurbain de la Ville de Niamey. Au total, 17 gîtes ont été identifiés dont cinq (5) gîtes permanents (29,41%). Les surfaces d’eau artificielles ont été plus abondantes (64,71%). L’étude sur la caractérisation des gîtes par la méthode ACP (Analyse par Composantes Principales) a permis de grouper les gîtes en trois (3) catégories: le groupe 1 constitué par des gîtes qui présentent un pH légèrement acide (6,075 à 7,035) et un taux d’oxygène dissout élevé (1,11 à 2,32). Le groupe 2 qui est constitué par des gites qui présentent une conductivité plus élevée (compris entre 0,97 à 1,08) ainsi qu’un pH légèrement alcalin (7,51 à 7,83). Quant aux gîtes du groupe 3, ils appartiennent en effet, à une zone de transition ou les trois (3) paramètres sont élevés à savoir le pH (8,02 à 8,36), le taux d’oxygène dissout (1,43 mg/l à 2,54 mg/l) et de la conductivité (1170 μS/cm à 1370 μS/cm). L’étude a mis en évidence des affinités entre les espèces de moustiques et les conditions physico-chimiques des gîtes larvaires. C’est ainsi que An. gambiae s.l abonde dans les gîtes caractérisés par une température moins élevée, un pH neutre un taux d’oxygène dissout élevé alors que Culex pipens présente une affinité aux gîtes à forte conductivité et à taux d’oxygène dissout faible.Mots clès : Culicidae, Paramètres physico-chimiques, gîtes larvaires, Saga, Niger.   English Title: Measurements of mosquito larvae proliferation indicators in the permanent and semi-permanent ponds of Saga, Niger Culicidae, commonly known as mosquitoes, by their wide distribution and abundance, are involved in the transmission of many human and animal diseases. The fight against these insects requires knowledge of their places of development in which the pre-imaginary stages evolve. The present study aims to characterize these breeding sites in order to identify entomological and ecological indicators of larval production in these environments. To do this, the pH, temperature, conductivity, dissolved oxygen content and larval density of culicidae were estimated following surveys of the breeding sites carried out from July 2007 to March 2018 in Saga, a peri-urban area of the City of Niamey. In total, 17 lodgings have been identified, including five (5) permanent lodgings (29.41%). Artificial water surfaces were more abundant (64.71%). The study on the characterization of the deposits by the ACP method (Principal Component Analysis) made it possible to group the deposits in three (3) categories: group 1 consisting of deposits that have a slightly acidic pH (6.075 to 7.035) and a high dissolved oxygen level (1.11 to 2.32). Group 2 which consists of gites which have a higher conductivity (0.97 to 1.08) as well as a slightly alkaline pH (7.51 to 7.83). As for the group 3 deposits, they indeed belong to a transition zone where the three (3) parameters are high, namely the pH (8.02 to 8.36), the dissolved oxygen level (1.43 mg / l to 2.54 mg / l) and conductivity (1170 μS / cm to 1370 μS / cm). The study highlighted affinities between mosquito species and the physicochemical conditions of the breeding sites. This is how An. Gambiae sl abounds in deposits characterized by a lower temperature, a neutral pH a high dissolved oxygen level while Culex pipens has an affinity for deposits with high conductivity and low dissolved oxygen rate.Keywords: Culicidae, Physico-chemical parameters, breeding sites, Saga, Niger.

Walleye (Sander vitreus) fingerlings (30 to 35 mm) are commonly reared in ponds filled with surface (i.e., lake) water, but the use of ground (i.e., well) water would provide increased biosecurity. We assessed the potential for using well water to rear walleye by comparing plankton and water quality over 30 days between organically fertilized lined ponds that were filled with either unfiltered lake or well water. All ponds were inoculated with plankton that originated from Blue Dog Lake, filled by May 15, 2020, and remained fishless. Zooplankton density and body size were consistently reduced in well ponds suggesting that fry survival and growth would be reduced. Initially, well ponds exhibited higher ammonia-nitrogen and alkalinity, but lower pH owing to the inherent chemistry of the well water. Later, reduced ammonia-nitrogen combined with increased dissolved oxygen and pH suggest that decomposition of the organic fertilizer occurred slower in well ponds. A phytoplankton bloom was successfully initiated but was difficult to maintain despite consistently lower zooplankton density in well ponds. While the use of well water would enhance biosecurity, these data suggest that walleye fingerling production would be reduced relative to lined ponds filled with productive, lake water. Increasing organic fertilizer, supplementing with liquid 28N:0P:0K, and/or filling ponds earlier (e.g., 30 days) may provide a more favorable environment for walleye culture in lined ponds filled with well water.
