All-sky imagers (ASIs) are used to record auroral activities from the ground but are often contaminated by the moon. Here, we studied the THEMIS ASIs data and developed an algorithm to eliminate the moon which can be generalized to other types of ASIs. With our algorithm, the ASI pixels within the moon's surface are typically saturated and thus rem...

Different shell characteristics (size, weight, aperture opening, aperture width, aperture height, shell length, width, depth and weight, digitations, spire whorls, outer lip, and the presence or absence of stromboid notch) were considered in identifying the specimens. Samples' identification was verified using the data and information from published illustrations and journal publications on different shell characteristics such as that of Kronenberg (1986Kronenberg ( , 2002Kronenberg ( , 2012, Kronenberg et al.

This study aimed to identify the microhabitat preference of Strombidae species present in selected intertidal zones of Zamboanga del Norte and Misamis Occidental. A total of 406 individuals of Strombidae were collected and identified into 15 species. Most species of Strombidae were recorded to be abundant in seagrasses (Cymodocea rotundata and Thalassia hemprichii) and in algae (Gracilaria salicornia, Ulva lactuca and Ulva intestinalis). Strombidae were also observed along rocks, muddy sand, black sand, sediments and tide pools. A Kruskal-Wallis Test showed that there was a significant difference in species abundance among different microhabitat types (H[6] = 13.46, p = 0.036). This implies that the abundance of species among different habitats was not the same. Supporting this, the Cramer’s contingency test revealed a significant association between the abundance of species to their microhabitat type with a contingency coefficient of 0.76. Canarium labiatum was observed to inhabit G. salicornia, while Canarium mutabile preferred both rocks and tide pools. Canarium urceus favored C. rotundata; Canarium (Canarium) esculentum occurred in G. salicornia and T. hemprichii. Conomurex luhuanus was observed in U. intestinalis and G. salicornia. Euprotomus aurisdianae inhabited the seagrass, while Euprotomus bulla occurred in T. hemprichii and muddy sand. Laevistrombus (Gonggonus) turturella inhabited the C. rotundata. Lastly, Lentigo lentiginosus and all Lambis species were noticed in G. salicornia. Strombidae preferred both seagrasses and algae apparently because these microhabitat types serve as food and nutrient sources to these species.
... In his description of E. aurora, Kronenberg (2002b) excluded the Pacific from the distribution of E. aurora, some records from the Pacific of E. aurora were published (Monsecour, 2004;Vermeij, 2005 [as E. bulla, but subsequently considered as E. aurora, Vermeij pers. comm. ...

... ay, 1852) and Rostellariella delicatula (Nevill, 1881) from the Arafura Sea, between the Aru Islands and Arnhem Land coast of the Northern Territory, Australia. As this locality is a long way from the presently known distribution of these species according to the literature and therefore quite unexpected, we put these new localities on record here. Kronenberg (2002) gave only Indian Ocean localities for Euprotomus aurora in the original description. Since then, some more localities have come to the attention of the authors, and we take the opportunity to record those as well. This is also the case for Dolomena hickeyi, originally described from off Queensland and Papua New Guinea (Willan 2000), but ...
... In the Pliocene to Recent strombid genus Euprotomus, known only from the western Pacific and Indian Oceans (Abbott 1960), the tip of the spire in two of the three species (E. bulla [see Figure 1F] and E. aurora) is coated with smooth callus, an extension of the broad inner-lip callus characteristic of this genus and of such related genera as Lentigo and Tricornis (see Kronenberg 2002;Kronenberg and Vermeij 2002). The third and only other known species of Euprotomus, E. aurisdianae, lacks the spire callus, as do members of the other strombid genera mentioned. ...
The taxonomy of the family Strombidae Rafinesque, 1815 is presented composed from the following sources: WoRMS database (World Register of Marine Species) or MolluscaBase, Existing literature and personal understanding of the phylogeny of Strombidae. Key-literature is listed in a literature section. It is not a definite listing: new species are described every year and new literature but also older literature is still missing in the literature section. Especially the extinct (fossil) species need adding and updating.
Two species, viz., Euprotomus bulla (Röding, 1798) and Tridentarius dentatus (Linnaeus, 1758) belonging to the family Strombidae are reported for the first time from the Andaman and Nicobar Islands, India. The close similarity in the morphological character sets between Euprotomous bulla and Euprotomous aurisdianae may be a reason for overlooking the former species by early workers. We have defined the dissimilarity between both species and have confirmed its occurrence in the Andaman and Nicobar Islands. In the genus Euprotomous, E. bulla is the second species reported from this region. Tridentarius dentatus has been previously reported from mainland India; however, it is reported from these islands for the first time. There exists a paucity of literature on Bufonaria elegans from Indian waters; however, it has been included in OBIS Indo—Pacific Molluscan Database from the vicinity of these Islands at an earlier date. As no comprehensive literature on its occurrence from Indian waters exists, the current report confirms its occurrence and provides notes on its morphology from this region.
The medium-sized, strongly ornamented nominal species Strombus schroeckingeri Hörnes in Hoernes &
Auinger, 1884 is well known from Langhian deposits of the Paratethys Sea. Its traditional generic affiliation in the literature with Euprotomus Gill, 1870, implicated a biogeographic relation of the Paratethys and the proto-Mediterranean with the Neogene Indo-West-Pacific region. This relation, however, is problematic because the Tethys Seaway was already closed or a very shallow, strongly evaporitic passage at that time. Despite its superficial similarity with extant genera of the IWP region, the genus is unrelated to all known strombid genera and represents a new genus, which is introduced herein as Europrotomus nov. gen. The genus comprises only one or maybe two species, which occur in the European Middle Miocene geological record. No ancestors are known so far. This sudden occurrence is discussed as immigration from an adjacent bioprovince rather than as a result of autochthonous evolution. Hypothetically, such a biogeographic source area might have been established along the coasts of tropical West Africa—a scenario that is already documented for Pleistocene times.
