The practices of licensed gun dealers can threaten the safety of urban residents by facilitating the diversion of guns to criminals. In 2003, changes to federal law shielded gun dealers from the release of gun trace data and provided other protections to gun dealers. The 14-month period during which the ...

Despite the 194 nation-state signatories to the global Convention on Biological Diversity, the conservation effort is failing to halt an ongoing spiral of decline in most habitats and ecological communities on land and ocean. Environmental ethicists argue that the failure to halt the unsustainable predation on the ecosystems that sustain ...

The 2011 meeting of the European Ecological Federation took place in Ávila, Spain, from 26th September to 29th September. The French Ecological Society (SFE) and the Foundation for Research on Biodiversity (FRB) sponsored a session entitled 'Evolutionary history, ecosystem function and conservation biology: new perspectives'. We report on the main ...

Seasonal abundance and activity of all the three post-embryogenic stages of Haemaphysalis longicornis, both feeding and free-living phases, were evaluated over a period of 2 years, from February 2008 to January 2010, in North China. Feeding ticks were removed weekly from head and ears of domestic sheep and the attachment sites ...

Abstract ABSTRACT: Mysidobdella californiensis n. sp. is described from the mysid Holmesimysis sculpta (Tattersall) from Bodega Bay on the central California coast and from Holmesimysis costata var. (Holmes) from San Pedro on the southern California coast. The internal anatomy of M. californiensis is similar to that of the only other ...

• Premise of study: The legume genus Vigna and close relatives have highly elaborated floral morphologies that involve the coiling, bending, and intricate connection of flower parts. Banners, levers, platforms, and pumps have evolved that attract pollinators and then manipulate their movement. Given this three-dimensional floral complexity, the taxonomy of ...

Both biogeography and ecology seek to understand the processes that determine patterns in nature, but do so at different spatial and temporal scales. The two disciplines were not always so different, and are recently converging again at regional spatial scales and broad temporal scales. In order to avoid confusion and ...

Traditional concepts of the Bering Land Bridge as a zone of predominantly eastward expansion from Eurasia and a staging area for subsequent colonization of lower latitudes in North America led to early inferences regarding biogeographic histories of North American faunas, many of which remain untested. Here we apply a host-parasite ...

Four new syringophilid species of Syringophiloidus Kethley, 1970 are described from North American passerines: S. zonotrichia n. sp. from Zonotrichia albicolis (Gmelin) (Emberizidae) on Texas; S. jackowiaki n. sp. from Poecile carolinensis (Auduborn) (Paridae) in Texas; and S. xanthocephalus n. sp. from Xanthocephalus xanthocephalus (Bonaparte) (Icteridae) and S. agelaius n. ...

Speciation remains one of the most controversial and least understood topics in evolution. About 75% of the earth's surface is covered by oceans. However, most of what we currently know about speciation is strongly biased toward terrestrial and freshwater organisms. Here, we discuss some of the major advances of the ...

Abstract Field-cage methods were developed to evaluate the abilities of Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) and Spathius agrili Yang (Hymenoptera: Braconidae), biocontrol agents of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), to parasitize, develop and overwinter following three late-season releases at both a northern (Michigan) and a southern (Maryland) location within the ...

In 1978, the nature of the hypnozoite was discussed in an article that appeared in a relatively obscure journal, which is also where the term was adopted for Plasmodium (a little-known fact). As a result, that commentary on the use of the word "hypnozoite" has been almost completely overlooked. Although ...

Theory predicts that the evolution of cooperative behaviour is favoured by low levels of promiscuity leading to high within-group relatedness. However, in vertebrates, cooperation often occurs between non-relatives and promiscuity rates are among the highest recorded. Here we resolve this apparent inconsistency with a phylogenetic analysis of 267 bird species, ...

Anoplocephalid cestodes have a worldwide distribution, but relatively few species are known from South American rodents. By examining the collections of the Harold W. Manter Laboratory of Parasitology and the United States National Parasite Collection, 6 new species of Monoecocestus Beddard, 1914, are described, along with a redescription of Monoecocestus ...

The study of 4 dasyatid stingrays- Dasyatis centroura (Mitchill, 1815), D. americana Hildebrand and Schroeder, 1928, D. say (Lesueur, 1817), and D. sabina (Lesueur, 1824)-from the northwestern Atlantic and the Gulf of Mexico showed the presence of monocotylid monogeneans Thaumatocotyle Scott, 1904 in their nasal fossae. Specimens collected from D. ...

Four new species belonging to Aulonastus Kethley, 1970 (Acari: Prostigmata: Syringophilidae), which are found inside the quills of body feathers of North American passerines (Aves: Passeriformes), are described and figured: A. emberizicus n. sp. from Ammodramus savanarum (Gmelin) (Emberizidae) (type-host) in Texas, Zonotrichia atricapilla (Gmelin) (Emberizidae) in California and Passerculus ...

In July 2010, during routine mosquito surveillance inspections at companies that import used tires, three invasive species were found at five locations in the Netherlands: the yellow fever mosquito (Aedes aegypti), the Asian tiger mosquito (Ae. albopictus), and the American rock-pool mosquito (Ae. atropalpus). This is the first time that ...

Xyleborinus octiesdentatus (Murayama), an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Alabama and Louisiana. This is the twenty-first species of exotic Xyleborina documented in North America. A re-description of the female and a key to the four North American ...

This article derives from a society-wide symposium organized by Timothy Bradley and Adriana Briscoe and presented at the 2009 annual meeting of the Society for Integrative and Comparative Biology in Boston, Massachusetts. David Grimaldi provided the opening presentation in which he outlined the major evolutionary events in the formation and ...

Considerable attention has been directed toward understanding the wide gaps in range that are common among many groups of closely related organisms. By placing their biology and geography in a phylogenetic context, we may gain a broader knowledge of the series of historical events that have led to present species ...

A number of international treaties address the conservation of marine resources. The declining state of the world's oceans suggests that these treaties are not succeeding and could use improvement. The Convention on International Trade in Endangered Species (CITES) is increasingly embracing the conservation of marine species. We examine the evolution ...

We described and illustrated Amanita viscidolutea sp. nov. from specimens collected in the state of Rio Grande do Norte, northeastern Brazil. The main characteristics of the new species are its yellow pileus with white margin, the viscidity of the pileal surface, an exannulate stipe and inamyloid basidiospores. We also present ...

Stomach nematodes were collected from 151 live American alligators, Alligator mississippiensis, from 3 lakes (Apopka, Griffin, and Woodruff) in north-central Florida using a gastric lavage technique. Four species were identified: Dujardinascaris waltoni, Ortleppascaris antipini, Brevimulticaecum tenuicolle, and larvae of Contracaecum sp. Of these, D. waltoni was the most prevalent species ...

The holothurians collected by the Royal Society Expedi tion to southern Chile, totalling 180 specimens, are described . Ten genera (of which one is new) and ten species are represented. Neopsolidium n.g., type species Psolidium convergens (Herouard), is erected to accommodate those species in the genus Psolidium (sensu lato) in ...

Wikstroemia (Thymelaeaceae) is a genus of tropical and subtropical shrubs or trees, widely distributed in southeast Asia to Malaysia, northeast Australia, and the Pacific islands (Ryukyu, Marianas, Caroline, Hawaiian, Society, Marquesas, Tonga, Fiji, Norfolk, and New Caledonia). The Hawaiian species are known by the name Akia or Akea.

We investigated two populations of Melittobia digitata Dahms, a gregarious parasitoid (primarily upon a wide range of solitary bees, wasps, and flies), in search of Wolbachia infection. The first population, from Xalapa, Mexico, was originally collected from and reared on Mexican fruit fly pupae, Anastrepha ludens Loew (Diptera: Tephritidae); the ...

We examined collections of pteridophytes from Moorea and others of the Society Islands, as well as literature relevant to the pteridophytes of Polynesia. This resulted in a list of species known to occur on Moorea, along with a list of species reported for Moorea but lacking voucher specimens, and a ...

Nineteen polychaete species belonging to five families, and representatives of two others not identified to species, are recorded from Viti Levu, Fiji. Most of the calcareous tubeworms (Serpulidae, Spirorbidae) were collected from shallow patch reefs in the Mba Passage off the northwest coast; the remaining worms came from the intertidal ...

About 1300 specimens of birds have been taken on the seven islands that constitute American Samoa in the southwestern Pacific Ocean; about 1200 specimens representing 43 species were examined. Information on the biology of these species, especially annual cycles of breeding and molt, is presented to the extent that it ...

The similarities between Opecoelus Ozaki, 1925, Coitocaecum Nicoll, 1915, Opegaster Ozaki, 1928 and Paropecoelus Pritchard, 1966 and the difficulty of separating Opecoelus and Opegaster are discussed. It is proposed that Opegaster be reduced to synonymy with Opecoelus and the diagnosis of the latter amended to accommodate both forms. Four new ...

Anuracanthorhynchus tritaxisentis n. gen., n. sp. from the intestines of the Brazilian frog Hylodes phyllodes (Leptodactylidae) is described and illustrated. Anuracanthorhynchus tritaxisentis n. gen., n. sp., is unique among the echinorhynchid Acanthocephala by possessing a spherical proboscis supporting a small number of hooks of equal size. It is the sixth ...

Efforts to conserve endangered species of animal are, in some important respects, at odds with Buddhist ethics. On the one hand, being abstract entities, species cannot suffer, and so cannot be proper objects of compassion or similar moral virtues. On the other, Buddhist commitments to equanimity tend to militate against ...

Pinus baileyi from the Paleogene of Idaho was initially related to the bristlecone pine P. longaeva (subgen. Strobus, sect. Parrya, subsect. Balfourianae) from western North America. Unlike the centromucronate condition in P. longaeva, P. baileyi cones have raised umbos that are excentromucronate, i.e., the mucro positioned in the upper umbo ...

Are greed and ruthlessness contrary to reason? Is immorality a form of irrationality? Much of contemporary ethical theory is a debate between Kantians, who argue that the dictates of morality are dictates of reason, and Humeans, who argue that reason is neutral between morality and immorality. The Kantian and Humean ...
