Fishers’ local ecological knowledge (LEK) is an additional tool to obtain information about cetaceans, regarding their local particularities, fishing interactions, and behavior. However, this knowledge could vary in depth of detail according to the level of interaction that fishers have with a specific species. This study investigated differences in small-scale fishers’ LEK regarding the estuarine dolphin (Sotalia guianensis) in three Brazilian northeast coastal communities where fishing is practiced in estuarine lagoons and/or coastal waters and where dolphin-watching tourism varies from incipient to important. The fishers (N = 116) were asked about general characteristics of S. guianensis and their interactions with this dolphin during fishing activities. Compared to lagoon fishers, coastal fishers showed greater knowledge about the species but had more negative interactions with the dolphin during fishing activities. Coastal fishing not only offered the opportunity for fishers to observe a wider variety of the dolphin’s behavior, but also implied direct contact with the dolphins, as they are bycaught in coastal gillnets. Besides complementing information that could be used for the management of cetaceans, this study shows that the type of environment most used by fishers also affects the accuracy of the information they provide. When designing studies to gather information on species and/or populations with the support of fishers, special consideration should be given to local particularities such as gear and habitats used within the fishing community. © 2014, Springer International Publishing Switzerland.

Polycopids are one of the most diverse and often very abundant ostracod group in the deep sea. The true diversity of poly-copids today inhabiting this environment, however, is very poorly known, because most of the studies identify ostracod material to the genus level, and they are based on the shell characters only. In this paper we describe Pseudopolycope (Pseudopolycope) andeep sp. nov. collected during the ANDEEP-SYSTCO I expedition in 2007 in the Atlantic Sector of the Southern Ocean. The new species was collected from 2,063 m depth. It differs from other 18 Recent Pseudopolycope Chavtur, 1981 species by (1) a peculiar morphology of the structures between claws on the uropodal lamellae; (2) mor-phology of the mandibular exopod; and (3) ornamentation of the shell. This is the first description of a living polycopid species from the deep Southern Ocean. Copyright © 2013 Magnolia Press. Source

Lepidonella is a small genus of scaled Paronellidae comprising 12 species distributed mainly across the Ethiopian, Oriental and Australian biogeographic regions. Most species are poorly described by current standards and little is known about their dorsal chaetotaxy. Previous observations of the chaetotaxy of the second and third abdominal segments led to suggestions that Lepidonella may be more closely related to Lepidocyrtus than to other paronellids, thus rendering Paronellidae polyphyletic. Here we describe the complete dorsal chaetotaxy of the Neotropical species, Lepidonella incerta (Mari Mutt, nec Handschin), and Lepidonella zeppelinii sp. nov., to evaluate the position of Lepidonella among genera of scaled Paronellidae. The abundant, largely undifferentiated chaetotaxy of L. incerta and L. zeppelinii sp. nov. suggests a basal position for Lepidonella among scaled Paronellidae. Putative synapomorphies of the chaetotaxy of the head and metathorax supporting the monophyly of Lepidonella lead us to conclude that most similarities in chaetotaxy between New World Lepidonella and Lepidocyrtus represent symplesiomorphies. We also conclude that Paronellidae s. lat. (i.e., including Cyphoderinae) is derived from an Orchesellinae or Heteromurini-like species and is sister to Entomobryinae. In addition, we describe L. zeppelinii sp. nov. from Brazil, the first member of the genus described for South America, we propose a new name, L. marimuti n. name, for L. incerta (Mari Mutt), which is a junior homonym of L. incerta (Handschin), transfer to the genus Trogolaphysa two species previously assigned to Lepidonella, and provide an identification key to the species of Lepidonella of the world.

This paper reviews recent developments regarding social housing policies in Hong Kong and the UK. Underlying the analysis is the fact that, during the last 40 years or so, both countries have been major global players in financial markets and thus pursued aggressive market-driven approaches to economic development. Notwithstanding that fact, each followed a different direction regarding housing policy reforms in the period. In Hong Kong (HK), the system of public housing provision was expanded; in the UK, the system of housing provision was scaled down. The argument being developed here is that a pro-public housing approach in HK should not be seen as a threat to capitalism in any way or measure. On the contrary, land development as well as land-originated fiscal revenues is a crucial part of HKSAR government's revenues. In the UK, this is no different. The return (through various forms of privatization) of the public housing stock (Council housing) to private hands (homeowners and housing associations) meant also to enhance businesses, in particular the mortgage and real estate markets. In both cases, there were also clear political reasons that justify developments in housing policy. The idea that Council housing served as a stage in the passage from a time when housing was predominantly provided in a largely unregulated private-rental market to a time when most people became homeowners is also discussed. This was what defined the 'modernization' of housing in the UK. The of 'residualization' was adopted to discuss the UK case. One important question is to know whether Hong Kong will follow the same path of 'modernization' as the UK, in the future. So far, HK has resisted; public housing has been 'resilient', ensured by a proper repair and maintenance policy, redevelopment and production of new housing throughout the last decades. Resilience is also granted by people's recognition and attachment to public housing and low stigmatization. More importantly, public provision of housing continues to be regarded, in both countries, as a necessary development to grant quality of life and a better distribution of income, avoiding the sharpening of social and territorial segregation, gentrification and stigmatization. © 2015 Elsevier Ltd.

We investigated the distribution of migratory shorebirds (Charadriidae and Scolopacidae) in three estuarine complexes along the coast of Paraíba, Brazil. We sought to answer the following questions: (1) Do species densities differ among habitats? (2) What factors (estuary, month, habitat type, and estuary size) have the greatest influence on variation in densities? (3) How similar are the survey sites, based on their speciescomposition and the structure of their assemblages of birds? We conducted 72 surveys between Sep 2010 and Apr 2011, recording 13 species of migratory shorebird. Type of habitat had the greatest influence upon variation in density. The species composition of open beaches was clearly different from that of inner estuarine habitats. Our findings suggest that estimates of shorebird numbers in estuarine complexes should include at least two strata, open beaches and inner habitats, to minimize the likelihood of failing to detect species with restricted distributions. © 2013, International Wader Study Group.
