Diaulota koreana,new species on Korean coasts with a discussion of its phylogenetic relationships (Coleoptera: Staphylinidae: Aleocharinae)

Diaulota koreana Yoo and Ahn new species is described in the intertidal zones of the southern part of the Korean peninsula and illustrations of diagnostic characters are presented. A cladistic analysis of the Liparocephalini based on 50 adult characters suggests that the new species belongs to the genus Diaulota Casey within the Liparocephalini. Similarities and differences among the liparocephaline genera are presented. Phylogenetic relationships of Diaulota koreana Yoo and Ahn new species among the Liparocephalini are briefly discussed.     

The western psychic as diviner: Experience and the politics of perception

Divination has been a well‐studied subject in the field of anthropology. Yet diviners within Western societies have been curiously ignored. Van Dijk's and Pels’ (1996) concept of the ‘politics of perception’ is discussed as a means of under‐standing why this is the case. Redressing this gap, I study the practices and experiences of an American psychic. This ethnographic material helps to move us beyond the patient‐client dialogue to address the internal processes of the diviners themselves. The reflexive exegesis of Elizabeth, an American diviner, reveals the spontaneous, visual nature of her practice and also highlights the role of the senses and emotions in divination. Other examples of sensory experience, such as in cases of blindness, show that those senses deemed lower down’ in the hierarchy of perception can be accurate modes of gaining knowledge of the world.     

Chromosome evolution in the owl monkey,Aotus

We have reported nine distinct karyotypes for Aotus, of four pelagic phenotypes, and suggest that this single species has undergone extensive subspeciation. We reconstruct the mechanism of chromosomal evolution and propose a hypothesis about the events of subspeciation in Aotus. We speculate that isolated groups of ancestral individuals living in several confined areas have separately accumulated a fusion or inversion pair as a result of inbreeding. A subsequent reassociation of descendants from these individuals led to the formation of offspring with mixtures of fusion or inversion pairs in their complements. They, in turn, radiated into different ecological niches accompanied by adaptive genetic changes and eventually gave rise to the present forms of Aotus distinguishable by their karyotypes, but not easily recognizable by ordinary taxonomic criteria.     

Interaction of cobalt(II) bovine carbonic anhydrase with pyridine-2,6-dicarboxylate ion and other chelating ligands

The removal of cobalt from cobalt(II) bovine carbonic anhydrase by pyridine-2-carboxylate, pyridine-2,6-dicarboxylate and 5-methyl-1,10-phenanthroline occurs via formation of an intermediate. This is presumed to be a ternary adduct of cobalt(II) enzyme with the ligand. In this, metal-protein bonds are loosened, probably via distortion of the normal geometry, resulting in accelerated breakdown of the adduct to apoprotein, compared with the behavior of the cobalt(II) enzyme alone. With 2-carboxy-1,10-phenanthroline, removal of metal is very rapid but no adduct is observed. Values of stability constants of the adducts and rate constants for their decomposition to apoprotein and their formation from apoprotein and cobalt(II) complex were measured at pH 5.5 and 25°C. Formation and dissociation rate constants for the adduct of cobalt carbonic anhydrase with pyridine-2,6-dicarboxylate could be measured from pH 5 to 7 and 10° to 25°C by stopped flow. Values of thermodynamic parameters for the various reactions agreed well with those estimated from the kinetic data.     

Older than New Caledonia emergence? A molecular phylogenetic study of the eneopterine crickets (Orthoptera: Grylloidea)

Aim A New Caledonian insect group was studied in a world‐wide phylogenetic context to test: (1) whether local or regional island clades are older than 37 Ma, the postulated re‐emergence time of New Caledonia; (2) whether these clades show evidence for local radiations or multiple colonizations; and (3) whether there is evidence for relict taxa with long branches in phylogenetic trees that relate New Caledonian species to geographically distant taxa. Location New Caledonia, south‐west Pacific. Methods We sampled 43 cricket species representing all tribes of the subfamily Eneopterinae and 15 of the 17 described genera, focusing on taxa distributed in the South Pacific and around New Caledonia. One nuclear and three mitochondrial genes were analysed using Bayesian and parsimony methods. Phylogenetic divergence times were estimated using a relaxed clock method and several calibration criteria. Results The analyses indicate that, under the most conservative dating scenario, New Caledonian eneopterines are 5–16 million years old. The largest group in the Pacific region dates to 18–29 Ma. New Caledonia has been colonized in two phases: the first around 10.6 Ma, with the subsequent diversification of the endemic genus Agnotecous, and the second with more recent events around 1–4 Ma. The distribution of the sister group of Agnotecous and the lack of phylogenetic long branches in the genus refute an assumption of major extinction events in this clade and the hypothesis of local relicts. Main conclusions Our phylogenetic studies invalidate a simple scenario of local persistence of this group in New Caledonia since 80 Ma, either by survival on the New Caledonian island since its rift from Australia, or, if one accepts the submergence of New Caledonia, by local island‐hopping among other subaerial islands, now drowned, in the region during periods of New Caledonian submergence.     

Taxonomic re-evaluation of the Taiwanese montane earthworm Amynthas wulinensis Tsai,Shen & Tsai, 2001 (Oligochaeta: Megascolecidae): Polytypic species or species complex?

Body size and colouration are two characters commonly used in the taxonomy of many animal taxa. However, they are seldom used by earthworm taxonomists because they are subject to environmental influences and tend to vary intraspecifically. In the present study, DNA sequences of the mitochondrial COI gene are used to evaluate whether specimens of the megascolecid earthworm Amynthas wulinensis Tsai, Shen & Tsai, 2001 that differ in body size and/or colouration belong to different genetic lineages. Phylogenetic analyses and morphological comparisons indicate that A. wulinensis in the previous broad sense is a species complex composed of three species differing in body size, colouration, and genital markings. Consequently, two new species, Amynthas lini and Amynthas meishanensis, are described. Taxonomic affinities of the A. wulinensis species complex are discussed, as is the feasibility of using body size and colouration in earthworm taxonomy.     

‘We eat meat every day’: ecology and economy of dietary change among Oaxacan migrants from Mexico to New Jersey

Abstract

In the late twentieth and early twenty-first centuries, the USA has experienced large-scale and continuing immigration from around the world, especially Latin America and, within Latin America, from Mexico. One dimension of these transnational processes is dietary change. In this paper, we qualitatively assess the effects of migration from Oaxaca, Mexico to central New Jersey on the ecology and economy of dietary patterns. We explore multiple factors at the micro and macro levels. Data come from focus groups held among Mexican migrants in New Jersey, and in Oaxaca among people from their sending communities. Economic constraints and lack of culturally appropriate foods are larger barriers to healthy eating than lack of knowledge about appropriate diets. We end with recommendations for nutrition education and interventions.

An assessment of the breeding range,colony sizes and population of the Westland petrel (Procellaria westlandica)

Abstract

The Westland petrel (Procellaria westlandica) is an endemic New Zealand species and one of the very few burrowing seabird species still breeding on mainland New Zealand. It nests only on a series of coastal ridgelines near to Punakaiki on the West Coast of the South Island. Between 2002 and 2005, surveys were undertaken at 28 of the 29 known colonies. The area occupied by the colonies was 73 ha; most colonies had fewer than 50 burrows, but six colonies had 201–500 burrows and four colonies had more than 1000 burrows. We find that the current breeding range of Westland petrel and the location of individual colonies are similar to those reported in both the 1950s and 1970s. Based on total burrow counts at 28 colonies and burrow occupancy rates determined by annual monitoring, the annual breeding population is estimated to be between 2954 and 5137 breeding pairs.     

The New Zealand falcon and wind farms: a risk assessment framework

Abstract

Internationally, birds of prey are often reported as being relatively prone to collision with wind turbines in comparison to other groups of birds. However, as yet it is unclear to what extent New Zealand's only endemic bird of prey, the New Zealand falcon (Falco novaeseelandiae), is at risk. In this paper we summarise the potential for wind farms to impact New Zealand falcon, evaluate the efficacy of a range of risk assessment and post-consent monitoring practices, and present options for mitigating and/or offsetting any residual effects. We conclude that the lack of knowledge on the effects of wind farms on New Zealand falcon is the result of inconsistency in the assessment methods thus far employed and the absence of a coordinated approach to monitoring methods and the dissemination of results. To remedy this we present a risk assessment framework that, if adopted, will provide the information necessary to ensure alternative energy targets can be met without compromising the conservation of this threatened species.
