Background Seagrasses (Zostera spp) are marine flowering plants that develop on sands and muds in sheltered intertidal and shallow subtidal areas. Seagrass beds are important marine habitats but are vulnerable to a range of human induced pressures. Their vulnerability and importance to habitat creation and ecological functioning is recognised in their inclusion on the recommended Priority Marine Features list for Scotland’s seas. Prior to this study, there were few confirmed records of Zostera in Orkney waters. This study combined a predictive modelling approach with boat-based surveys to enhance under- standing of seagrass distribution in Orkney and inform conservation management.

Box 100.644, Niterói, 24001-970 Brazil ABSTRACT A population of the tanaidacean, Kalliapseudes schubartii Mañé-Garzón, 1949 was sampled monthly in order to study its life cycle in a southeastern Brazilian tropical lagoon. The species’ density changed seasonally, increasing in the beginning of the wet season and presenting peaks following precipitation peaks in other periods. Density changed due to oscillations in numbers of larval stages and juveniles. Females were larger than males, and the size at onset of sexual maturity of females was 5.9 mm. The sex-ratio was female-skewed during all months, in accordance with studies of the same species at other sites along the Brazilian coast and on other species of tanaids. Ovigerous females and other developmental stages were observed in all samples. Peaks in the frequencies of larval stages and juveniles were followed by peaks in ovigerous female frequency. Comparisons of populations of K. schubartii at different sites along the Brazilian coast showed an intraspecific difference in their life cycles according to a latitudinal gradient, with longer reproductive activity occurring in the tropics.

    This is a post-peer-review, pre-copyedit version of a chapter published in “Species Diversity of Animals in Japan” (Motokawa M, Kajihara H, editors). The final authenticated version is available online at: https://doi.org/10.1007/978-4-431-56432-4_23. Chapter 23 Review of the Taxonomy, Diversity, Ecology, and Other Biological Aspects of Order Tanaidacea from Japan and Surrounding Waters Keiichi Kakui Faculty of Science, Hokkaido University, Sapporo, Hokkaido 060-0810, Japan e-mail: [email protected] telephone: +81-11-706-2750 Abstract The order Tanaidacea is a group of benthic crustaceans, most of which are small, up to a few millimeters long. Tanaidaceans are distributed worldwide, with more than 1,200 described species. Following the first taxonomic paper on a Japanese tanaidacean in 1936, many researchers have studied their taxonomy, morphology, reproductive biology, or ecology in the waters around Japan. This chapter presents a brief introduction to tanaidaceans and then reviews what is known of their systematics (taxonomy and phylogeny), biology (including feeding habits, phenology, morphology, reproductive modes, parasites, predators), and ecology in Japan. The chapter ends with a summary and prospects for future research. The general conclusion is that tanaidaceans have been under-studied, both globally and within Japan; the 104 nominal species reported from around Japan and the 1,200 species reported globally likely represent a fraction of the actual diversity. The phylogeny of tanaidaceans is largely unresolved at all taxonomic levels. Recent, significant new discoveries dealing with herbivory, selfing, skin-digging activity in holothuroid hosts, possible sound production, and tube building suggest that much remains to be learned about their general biology.

[email protected] Abstract Magellanic tanaidacean faunas have been mainly studied in the Magellan Strait and Beagle Channel, the latter restricted to bot- toms deeper than 40m. As a result, the shallow rocky bottoms of the Magellanic fjords remain largely under-studied, and their tanaidacean diversity is poorly known. In this study, tanaidacean species sampled from shallow rocky bottoms of Chilean fjords are investigated, and morphological and taxonomic considerations included. A new species of the Tanaidae, Zeuxoides tronco- soi sp. nov. is described. The genus Leptochelia is recorded for the first time in Chile, and the distribution of Pancoloides lito- ralis is extended northwards. Specimens collected of Pancoloides litoralis and Nototanais dimorphus present morphological differences with previous descriptions, which are at present attributed to intraspecific variation derived from geographical iso- lation among populations, until sufficient material can be examined to determine what constitutes interspecific and intraspecific variation.

Breve descripción del grupo y principales caracteres diagnósticos Los Tanaidacea son crustáceos peracáridos de pequeño tamaño (no más de 2 cm de longitud) de distri- bución universal. Son bénticos, la mayoría marinos aunque también los hay salobres y de agua dulce. Los hay libres, pudiendo nadar pocos centímetros, excavadores de galerías, constructores de tubos e incluso se conocen especies parásitas de holoturias. Se han encontrado hasta a más de 9.000 metros de profun- didad. Hay poco registro fósil (11 especies), siendo el primero conocido del Carbonífero inferior. A nivel taxonómico son Artrópodos del Subphylum Crustacea, catalogados en la Clase Malacostra- ca, Subclase Eumalacostraca. El Orden se sitúa bajo el Superorden Peracarida junto a 11 órdenes más. Los Tanaidacea presentan cefalotórax, primer pereiópodo quelado, generalmente seis segmentos torácicos libres, normalmente cinco somitos abdominales provistos de pleópodos y un pleotelson que acaba en un par de urópodos. La forma del rostro, el número de pereionitos y de pleonitos, el número de artejos, longitud relativa y fanerotaxia de las antenas son caracteres generales utilizados para la clasifica- ción del grupo. Con más frecuencia se utiliza el número de ramas de los urópodos, el marsupio, la morfo- logía y número de artejos de los pereiópodos, el quelípedo y, en especial, la morfología de las piezas bucales.
