AbstractLutraria rhynchaena Jonas, 1844 is of great commercial interest, but its reserves have dramatically declined over recent decades. Therefore, there is an urgent need of scientific basis to propose effective fishery management measures and improve artificial aquaculture of the clam. In this study, we investigated the distribution and density of L. rhynchaena, sediment characteristics, and established the clam’s reproductive cycle through monthly observations from August 2017 to July 2018. The study results showed that distribution and density of clams are related to sediment types, and the sediment type of medium sand is likely the best benthic substrate for the clams. The spawning of clams occurred throughout the year with three spawning peaks in January, April and September. For the sustainable management of the clam resource in Cat Ba-Ha Long Bay, the fishery authorities can issue a ban on harvest of the clam in spawning peak months in January, April and September.

Venous Plasma

Concentrations of progesterone in arterial and ovarian, uterine and jugular venous plasma were determined in four Barbary sheep at various stages of pregnancy. The results, together with ovarian histology, show that the corpus luteum regresses before term in Barbary sheep, as in most breeds of domestic ewes. Uterine synthesis of progesterone was demonstrated in late pregnancy in two animals in which uterine venous levels of progesterone were increased two- to fourfold above arterial concentrations. The placenta contained 3β-hydroxysteroid dehydrogenase. Barbary sheep (diploid chromosome number, 2N = 58) therefore resemble the domestic sheep (2N = 54) rather than the goat (2N = 60) from the point of view of the source of the progesterone required for maintenance of pregnancy.

<p>Understanding the niche and habitat requirements of useful and threatened species, their shifts under climate change and how well protected areas (PAs) preserve these habitats is relevant for guiding sustainable management actions. Here we assessed the ecological factors underlying the distribution of two multipurpose and threatened species, <i>Mimusops andongensis</i> and <i>M</i>. <i>kummel</i>, in Benin, and potential changes in the suitable habitats covered by PAs, under climate change scenarios. Fifty seven occurrence points were collected for <i>M</i>. <i>andongensis</i> and 81 for <i>M</i>. <i>kummel</i>. </p>

ABSTRACT: Bluetongue (BT) is an infectious and non-contagious disease of compulsory notification which may affect domestic and wild ruminants, transmitted by Culicoides spp. midges. Despite the high morbidity and mortality in sheep, role of wild animals in the BT cycle remains unclear. Caprine arthritis-encephalitis (CAE) and Maedi-Visna virus (MVV) have been reportedly found in goats and sheep, but not described in wildlife species. Accordingly, serum samples from 17 captive Barbary sheep (Ammotragus lervia) from Curitiba zoo, southern Brazil, were tested for bluetongue, caprine arthritis-encephalitis (CAE) and Maedi-Visna viruses by agar gel immunodiffusion (AGID) and enzyme linked immunosorbent assay (ELISA). Antibodies for bluetongue were observed in 6/17 (35.3%) Barbary sheep by AGID test and in 7/17 (41.2%) by ELISA. All samples were negative for the presence of antibodies against caprine arthritis-encephalitis (CAE) and Maedi-Visna viruses. These findings indicate that Barbary sheep may be infected by bluetongue virus and act as wildlife reservoir in both captive and free-range environments.
