Elasmobranchs are critical to tourism industries worldwide. In French Polynesia, where ecotourism is the second most important industry, little is known about the spatiotemporal distribution of eagle rays. This study represents the first investigation into habitat use and behaviour of ocellated eagle rays (Aetobatus ocellatus) in French Polynesia focused on two sites with different levels of anthropogenic noise. Environmental variables and biological data were recorded over a one-year period to explore the distribution patterns of...

Effect of environmental change after the 2011 tsunami on the population dynamics of Japanese tubesnout Aulichthys japonicus (Gasterosteiformes)

Go Katayose & Takashi Asahida
The Japanese tubesnout Aulichthys japonicus Brevoort, 1862 is a small fish species, which lives in shallow coastal waters, especially in seagrass (Zostera spp.) beds. The fish is known for their unusual spawning behaviour of concealing their eggs in ascidians (Halocynthia roretzi). By studying the larval and juvenile fish fauna in a seagrass bed in southern Iwate, Japan since 2007, we observed that A. japonicus was a dominant species. On 11 March 2011, the seagrass bed...

Are mangroves important for reef fish on Mayotte Island (Indian Ocean)?

Rakamaly Madi Moussa
In order to understand the potential role of the mangroves of Mayotte Island for reef fishes, sampling was conducted monthly from April 2016 to April 2017 in three sites along a mangrove fringe: Bandrélé near fringing reef, Dzoumogné close to a river mouth and Malamani in a bay. Fishes were sampled using a fyke-net combined with visual census surveys (UVC) and eight environmental variables were recorded at each site to determine their relationship with the...

Почвообразование на техногенных озёрных илах

Е.В. Дабах
Статья посвящена почвам техногенного ландшафта (Technosols по WRB), формирующимся на загрязнённых техногенных озёрных отложениях, вышедших на дневную поверхность после изменения гидрологического режима и прекращения поступления в озеро загрязнённых сточных вод. Исследуемая территория расположена в долине р.Вятки в районе хвостохранилищ химических предприятий г. Кирово-Чепецка (Кировская область, Россия). Мощность почвенного профиля ограничена плотной гипсовой коркой, залегающей на глубине 30 см и способствующей переувлажнению почв. В отличие от окружающих кислых аллювиальных почв, они характеризуются щелочной реакцией, контрастностью верхней...

Изменение почвенной актинобиоты под влиянием инвазии борщевика Сосновского

Е.В. Товстик, И.Г. Широких, Е.С. Соловьёва, А.А. Широких, Т.Я. Ашихмина & В.П. Савиных
Отдельные виды растений, а также растительные сообщества могут существенно влиять на структуру и разнообразие почвенных микробных сообществ. Актиномицеты являются неотъемлемым компонентом почвенной микробной системы, осуществляющей важные экологические функции, связанные, в числе прочих, с трансформацией органического вещества. Настоящее исследование было проведено для выявления различий в структуре почвенных актиномицетных комплексов между участками, заросшими борщевиком Сосновского (Heracleum sosnowskyi Manden.) и неинвазированными (контрольными) участками. Отмечено увеличение родового и видового разнообразия актиномицетов в инвазированных почвах, по сравнению с контролем, в...

EOR-1 mediates non-cell autonomous regulation of abts-1 gene expression in HSNs

Yoichi Shinkai & Motomichi Doi
In the present study, we investigated whether abts-1 expression in HSNs is dependent on neuronal activities through synaptic transmission. abts-1 is expressed in HSNs from the L4 larval stage onward (Shinkai et al. 2018). To measure abts-1 expression levels in HSNs, we used transgenic worms carrying vsIs138 [Pabts-1b::gfp, lin15(+)]. Quantitative fluorescent measurements were performed as previously described (Shinkai et al. 2018). Since presynaptic inputs are important for the GABA functional switch, we investigated the effect...

wrt-2 expression oscillates during larval development

Ana G. Vera-Cruz, Siavash Amon, Sabih Rashid & Lesley T. MacNeil
wrt-2 encodes a hedgehog-like protein that is weakly required for molting (Kouns et al., 2011). As monitored using a transcriptional GFP reporter, wrt-2 is expressed in seam and hypodermal cells throughout development (Apock et al., 1999). However, wrt-2 transcript levels oscillate with a period consistent with the timing of the molting cycle (Hendriks et al., 2014). Because standard GFP reporters do not capture rapid changes in gene expression, we generated a wrt-2 transcriptional reporter driving...

A Theory of Undamageable Graphene

George Z. VOYIADJIS & Peter I. KATTAN
It is the aim of this work to develop and extend the theory of undamageable materials to graphene. An undamageable material is a material where the value of the damage variable remains zero throughout the deformation process. It is anticipated that the constitutive equations for undamageable graphene can be modeled with differential equations for the case of graphene. The equations are solved for three cases: n = 1, n = 2, and the general case...

Direct N-body code designed for heterogeneous platforms

David Goz, Luca Tornatore, Sara Bertocco & Giuliano Taffoni
The ExaNeSt H2020 project aims at the design and development of an exascale ready supercomputer with a low energy consumption profile but able to support the most demanding scientific and technical applications. The project will produce a prototype based on hybrid hardware (CPUs+accelerators) implementing a co-design approach where scientific applications requirements are driving the hardware design. Astrophysical codes are playing a fundamental role to validate the exascale platform. We present strategies adopted in order to...
