Waste Deposit

Four strains of a novel yeast species were isolated from laboratory nests of the leaf-cutting ant Atta sexdens in Brazil. Three strains were found in older sponges and one was in a waste deposit in the ant nests. Sequencing of the D1/D2 region of the large-subunit rRNA gene showed that the novel species, named Sympodiomyces attinorum sp. nov., is phylogenetically related to Sympodiomyces parvus. Unlike Sympodiomyces parvus, Sympodiomyces attinorum can ferment glucose, assimilate methyl α-d-glucoside, salicin and citrate, and grow at 37 °C, thus enabling these two species to be distinguished. Differentiation from other related species is possible on the basis of other growth characteristics. The type strain of Sympodiomyces attinorum is UNESP-S156T (=CBS 9734T=NRRL Y-27639T).

Mycobacterium Simiae

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scotochromogenic slow growers and are genetically related to the group that included Mycobacterium simiae and 15 other species. The novel species Mycobacterium europaeum sp. nov. is proposed to accommodate these five strains. Strain FI-95228T ( = DSM 45397T  = CCUG 58464T) was chosen as the type strain. In addition, a thorough revision of the phenotypic and genotypic characters of the species related to M. simiae was conducted which leads us to suggest the denomination of the ‘Mycobacterium simiae complex’ for this group.

We isolated a strain coded Esc2AmT during a study focused on the microbial diversity of adult specimens of the bark beetle Hylesinus fraxini. Its 16S rRNA gene sequence had 99.4 % similarity with respect to its closest relative, Pseudomonas rhizosphaerae IH5T. The analysis of partial sequences of the housekeeping genes rpoB, rpoD and gyrB confirmed that strain Esc2AmT formed a cluster with P. rhizosphaerae IH5T clearly separated from the remaining species of the genus Pseudomonas. Strain Esc2AmT had polar flagella and could grow at temperatures from 4 °C to 30 °C. The respiratory quinone was Q9 and the main fatty acids were C16 : 0, C18 : 1ω7c and/or C18 : 1ω6c in summed feature 8 and C16 : 1ω7c and/or C16 : 1ω6c in summed feature 3. DNA–DNA hybridization results showed 51 % relatedness with respect to P. rhizosphaerae IH5T. Oxidase, catalase and urease-positive, the arginine dihydrolase system was present but nitrate reduction and β-galactosidase production were negative. Aesculin hydrolysis was positive. Based on the results from the genotypic, phenotypic and chemotaxonomic analyses, we propose the classification of strain Esc2AmT as representing a novel species of the genus Pseudomonas, for which we propose the name Pseudomonas coleopterorum sp. nov. The type strain is Esc2AmT ( = LMG 28558T = CECT 8695T).

Species Analysis

A polyphasic taxonomic evaluation of presumptive strains representative of the genus Glycomyces held within the Agricultural Research Service Culture Collection resulted in the discovery of three novel species. Analysis of the whole cell sugar content of these novel species, as well as of two species presently assigned to the genus, revealed that the whole cell sugar pattern was different from that reported in the formal description of the genus Glycomyces. The sugars present in all strains studied included ribose, xylose, mannose and galactose rather than xylose and arabinose as reported in the original description of the genus. Moreover, the menaquinone patterns observed for the novel species also deviated from the original genus description. The formal description of the genus Glycomyces is emended to reflect these new data. The novel species proposed and described are Glycomyces algeriensis sp. nov. (type strain NRRL B-16327T=DSM 44727T), Glycomyces arizonensis sp. nov. (type strain NRRL B-16153T=DSM 44726T) and Glycomyces lechevalierae sp. nov. (type strain NRRL B-16149T=DSM 44724T).

Six isolates recovered from coffee seeds giving off a potato-like flavour were studied. Gene sequencing (rrs and rpoB) showed they belong to the genus Pantoea . By DNA–DNA hybridization, the isolates constituted a genomic species with less than 17 % relatedness to 96 strains representing enterobacterial species. Multilocus sequence analysis (gyrB, rpoB, atpD and infB genes) showed the isolates to represent a discrete species of the genus Pantoea . Nutritional versatility of the novel species was poor. The novel species is proposed as Pantoea coffeiphila sp.nov. and its type strain is Ca04T ( = CIP 110718T = DSM 28482T).

Two novel yeast species, Candida aechmeae sp. nov. and Candida vrieseae sp. nov., were isolated from bromeliads in Itapuã Park, Rio Grande do Sul, Brazil. These species are genetically isolated from all other currently recognized ascomycetous yeasts based on their sequence divergence in the D1/D2 domain of the LSU rRNA gene. C. aechmeae sp. nov. is phylogenetically close to Candida ubatubensis, a species also isolated from bromeliads in Brazil, but the novel species can be differentiated on the basis of differences in the D1/D2 domain and positive results for the assimilation of l-arabinose, raffinose, inulin and citrate. Candida vrieseae sp. nov. is phylogenetically placed in a clade near Candida membranifaciens that is composed of several species associated with insects, but the novel species can be differentiated from them by the D1/D2 and ITS gene sequences, positive results for the assimilation of nitrite and a negative result for the assimilation of ethylamine. The type strain for Candida aechmeae sp. nov. is BI153T (=CBS 10831T=NRRL Y-48456T) and the type strain for C. vrieseae sp. nov. is BI146T (=CBS 10829T=NRRL Y-48461T).

Adaptive Thresholds

Human activity alters natural habitats for many species. Understanding variation in animals' behavioural responses to these changing environments is critical. We show how signal detection theory can be used within a wider framework of state-dependent modelling to predict behavioural responses to a major environmental change: novel, exotic species. We allow thresholds for action to be a function of reserves, and demonstrate how optimal thresholds can be calculated. We term this framework ‘state-dependent detection theory’ (SDDT). We focus on behavioural and fitness outcomes when animals continue to use formerly adaptive thresholds following environmental change. In a simple example, we show that exposure to novel animals which appear dangerous—but are actually safe—(e.g. ecotourists) can have catastrophic consequences for ‘prey’ (organisms that respond as if the new organisms are predators), significantly increasing mortality even when the novel species is not predatory. SDDT also reveals that the effect on reproduction can be greater than the effect on lifespan. We investigate factors that influence the effect of novel organisms, and address the potential for behavioural adjustments (via evolution or learning) to recover otherwise reduced fitness. Although effects of environmental change are often difficult to predict, we suggest that SDDT provides a useful route ahead.

Mango Leaves

Five strains of a novel methanol-assimilating yeast species were isolated from mango (Mangifera indica) leaves collected at the campus of the Federal University of Minas Gerais in Brazil. The sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit of the rRNA gene showed that this species belongs to the Ogataea clade and is related to O. allantospora, O. chonburiensis, O. dorogensis, O. kodamae, O. paradorogensis and Candida xyloterini (Ogataea clade). The novel species differs in the D1/D2 domains of the large subunit of the rRNA gene by 12 to 40 substitutions from these Ogataea species. The name Ogataea mangiferae sp. nov. is proposed for this novel species. The type strain of Ogataea mangiferae sp. nov. is UFMG-CM-Y253T ( = CBS 13492T). The Mycobank number is MB 811646.
