Short Term Response of Ants to the Removal of Ground Cover in Organic Olive Orchards
Eur. J. Entomol. 108: 417–423, 2011 http://www.eje.cz/scripts/viewabstract.php?abstract=1632 ISSN 1210-5759 (print), 1802-8829 (online) Short term response of ants to the removal of ground cover in organic olive orchards MERCEDES CAMPOS1, LUISA FERNÁNDEZ1, FRANCISCA RUANO3, BELÉN COTES1, MANUEL CÁRDENAS1 and JUAN CASTRO2 1Department of Environmental Protection, Estación Experimental del Zaidín, (CSIC) C/Profesor Albareda n° 1, 18008 – Granada, Spain; e-mail: [email protected] 2IFAPA Centro Camino de Purchil, CAP (Junta de Andalucia), P.O.

Ants are the most abundant group of soil arthropods in olive groves where they are involved in various trophic relation- ships of great importance for crops. The system of soil management is one agricultural practice that has a great effect on ants, so the objective of this study was to compare ant populations in organic olive orchards with a ground cover of natural vegetation and others where this natural vegetation is mechanically removed at the beginning of June. Ants were sampled using pitfall traps at 14, 30, 70 and 90 days after the removal of the ground vegetation. Overall, ant biodiversity did not change. However, changes were observed in the abundance of ant species, in particular, in those species that build shallow nests in the soil, both between the rows of trees and under the canopy of olive trees. In contrast, deep nesting species, such as Messor barbarus, were not affected. -
ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects
NINE Phylum ARTHROPODA SUBPHYLUM HEXAPODA Protura, springtails, Diplura, and insects ROD P. MACFARLANE, PETER A. MADDISON, IAN G. ANDREW, JOCELYN A. BERRY, PETER M. JOHNS, ROBERT J. B.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000). -
Hymenoptera: Formicidae
16 The Weta 30: 16-18 (2005) Changes to the classification of ants (Hymenoptera: Formicidae) Darren F. Ward School of Biological Sciences, Tamaki Campus, Auckland University, Private Bag 92019, Auckland ([email protected]) Introduction This short note aims to update the reader on changes to the subfamily classification of ants (Hymenoptera: Formicidae). Although the New Zealand ant fauna is very small, these changes affect the classification and phylogeny of both endemic and exotic ant species in New Zealand. Bolton (2003) has recently proposed a new subfamily classification for ants. Two new subfamilies have been created, a revised status for one, and new status for four. Worldwide, there are now 21 extant subfamilies of ants. The endemic fauna of New Zealand is now classified into six subfamilies (Table 1), as a result of three subfamilies, Amblyoponinae, Heteroponerinae and Proceratiinae, being split from the traditional subfamily Ponerinae. Bolton’s (2003) classification also affects several exotic species in New Zealand. Three species have been transferred from Ponerinae: Amblyopone australis to Amblyoponinae, and Rhytidoponera chalybaea and R. metallica to Ectatomminae. Currently there are 28 exotic species in New Zealand (Table 1). Eighteen species have most likely come from Australia, where they are native. Eight are global tramp species, commonly transported by human activities, and two species are of African origin. Nineteen of the currently established exotic species are recorded for the first time in New Zealand as occurring outside their native range. This may result in difficulty in obtaining species-specific biological knowledge and assessing their likelihood of becoming successful invaders. In addition to the work by Bolton (2003), Phil Ward and colleagues at UC Davis have started to resolve the phylogenetic relationships among subfamilies and genera of all ants using molecular data (Ward et al, 2005). -
Notification of Access Arrangement for MP 41279, Mt Te Kuha
Attachment C Draft Terrestrial Ecology Report 106 VEGETATION AND FAUNA OF THE PROPOSED TE KUHA MINE SITE Prepared for Te Kuha Limited Partnership October 2013 EXECUTIVE SUMMARY The Te Kuha mining permit is located predominantly within the Westport Water Conservation Reserve (1,825 ha), which is a local purpose reserve administered by the Buller District Council. The coal deposit is situated outside the water catchment within an area of approximately 490 ha of Brunner Coal Measures vegetation approximately 5 km southwest of Mt Rochfort. Access would be required across conservation land to reach the coal resource. The Te Kuha site was recommended as an area for protection by the Protected Natural Areas Programme surveys in the 1990s on the basis that in the event it was removed from the local purpose reserve for any reason, addition to the public conservation estate would increase the level of protection of coal measures habitats which, although found elsewhere (principally in the Mt Rochfort Conservation Area), were considered inadequately protected overall. The proposal to create an access road and an opencast mine at the site would affect twelve different vegetation types to varying degrees. The habitats present at the proposed mine site are overwhelmingly indigenous and have a very high degree of intactness reflecting their lack of human disturbance. Previous surveys have shown that some trees in the area are more than 500 years old. Habitats affected by the proposed access road are less intact and include exotic pasture as well as regenerating shrubland and forest. Te Kuha is not part of the Department of Conservation’s Buller Coal Plateaux priority site and is unlikely to receive management for that reason. -

Myrmecological News 17 91-104 Vienna, August 2012 A review of the West Palaearctic species of the ant genus Bothriomyrmex EMERY, 1869 (Hymenoptera: Formicidae) Bernhard SEIFERT Abstract The taxonomic status of 32 taxa of the ant genus Bothriomyrmex from Europe, North Africa, Asia Minor, and the Middle East was assessed and commented. Four European species were clearly distinguished by high-performance stereomicro- scopy, reproducible numeric recording of 18 phenotypical characters and multivariate analyses: B. meridionalis ROGER, 1863, B. atlantis FOREL, 1894, B. communistus SANTSCHI, 1919 and B. corsicus SANTSCHI, 1923. Type investigation and evaluation of original descriptions established that there is definitely no Palaearctic taxon described before 31 March 1923 which is a senior synonym to any of these four names. Principal component (PCA) and discriminant analyses (DA) of 204 workers and 58 gynes clearly showed the following synonymies (in brackets posterior probabilities of type spe- cimens in discriminant analyses): B. meridionalis var. adriaca SANTSCHI, 1922 (p = 1.000) and B. corsicus ssp. mohel- ensis NOVÁK, 1941 (p = 1.000) are synonyms of B. communistus SANTSCHI, 1919 (p = 1.000) while B. meridionalis ssp. gibbus SOUDEK, 1924 (p = 0.999), B. corsicus ssp. gallicus EMERY, 1925 (p = 1.000), B. corsicus var. ligurica EMERY, 1925 (p = 1.000), and B. menozzii EMERY, 1925 (p = 1.000) are synonyms of B. corsicus SANTSCHI, 1923 (p = 1.000). The performance of the DA was unexpectedly strong: After reduction to eight morphological characters, any individual of B. communistus and B. corsicus was classified with posterior probabilities of p > 0.960 and the error rate in leave-one-out cross-validation was 0%. -
Hybridization in Ants
Rockefeller University Digital Commons @ RU Student Theses and Dissertations 2020 Hybridization in Ants Ian Butler Follow this and additional works at: https://digitalcommons.rockefeller.edu/ student_theses_and_dissertations Part of the Life Sciences Commons HYBRIDIZATION IN ANTS A Thesis Presented to the Faculty of The Rockefeller University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Ian Butler June 2020 © Copyright by Ian Butler 2020 HYBRIDIZATION IN ANTS Ian Butler, Ph.D. The Rockefeller University 2020 Interspecific hybridization is a relatively common occurrence within all animal groups. Two main factors make hybridization act differently in ants than in other species: eusociality and haplodiploidy. These factors serve to reduce the costs of interspecific hybridization in ants while simultaneously allowing them to take advantage of certain benefits. Eusociality may mitigate the effects of hybridization by allowing hybrids to be shunted into the worker caste, potentially reducing the effects of hybrid sterility. In haplodiploid species, males do not have a father. They instead develop from unfertilized eggs as haploid clones of their mother. This means that interspecifically mated queens do not completely sacrifice reproductive potential even if all hybrids are sterile because they can still produce fertile males. These factors in turn suggest that hybridization should be more common among the social Hymenoptera than other animal groups. Nevertheless, current data suggest that ants hybridize at rates similar to other animal groups, although these data are limited. Furthermore, there is a large amount of overlap between cases of interspecific hybridization and cases of genetic caste determination. A majority of the cases in ants where caste is determined primarily by genotype are associated with hybridization. -
The Spatial Distribution of Wood-Nesting Ants in the Central
AN ABSTRACT OF THE THESIS OF Gary R. Nielsen for the degree of Doctor of Philosophy in Botany and Plant Pathology presented on March 6, 1986. Title: The Spatial Distribution of Wood-Nesting Ants in the Central Coast Range of Oregon / 4 Abstractapproved: Redacted for privacy Fred okickson Two coniferous forests in the central Coast Range of western Oregon were surveyed for nests of wood inhabiting ants.Nineteen species and 825 ant nests were found, corresponding to an average nest density of 0.079 nests/m2 (maximum 0.38/m2) and a mean species density of 0.026 species/m2 (maximum 0.08/m2). The spatial distribution of all species was random within the study areas In contrast, the nest distribution patterns of the six most common species and all ants combined were found to be highly clumped (contagious) due to high nest densities on a few favorable sites. Most ants achieved greatest nest densities on high imsdlatim, early successional plots such as clear- cuts. The nest abundances of 15 species were negatively correlated with tree canopy cover. However, Lasius pallitarsis and Leptothorax nevadensis had higher nest densities in woody debrison forested plots. Furthermore, the nest densities of all ants combined, and of nine individual species were greater in stumps than logs. Within stumps, the nests of all species combined, as well as Camponotus modoc, Tapinoma sessile, and Lasius pallitarsis were concentratedon the south sides of stumps.The bark, cambial zone, and wood of woody debris in all stages of decompositionwere exploited by ants for nest sites. Leptothorax nevadensis, Tapinoma sessile, and Aphaenogaster subterranea occupied bark significantly more often than other tissues. -
On the Metapleural Gland of Ants
ON THE METAPLEURAL GLAND OF ANTS BY BERT HOLLDOBLER AND HILTRUD ENGEL-SIEGEL Department of Organismic and Evolutionary Biology, MCZ-Laboratories, Harvard University Cambridge, Massachusetts |NTRODUCTION The metapleural gland (also called metasternal or metathoracic gland), a complex glandular structure located at the posterolateral corners of he alitrunk is peculiar to the ants. Although the gland was noted by Meinert (1860) and Lubbock (1877), it was Janet (1898) who conducted the first detailed anatomical study of this organ, as part of his classic work on Myrmica rubra. Additional details have been added by Tulloch (1936) on Myrmica laevinodis; by Whelden (1957a, b, 1960, 1963) on Amblyopone (Stigmatomma)pallipes, Rhytidoponera convexa, R. metallica, Eciton burchelli, E. ham- atum; by Tulloch et al (1962) on Myrmecia nigrocincta; and by Ktirschner* (1970) on Formica pratensis. It is generally assumed that the metapleural gland is a universal and phylogenetically old character of the Formicidae. Even the. extinct species Sphecomyrmafreyi of Cretaceous age appears to have possessed a metapleural gland (Wilson et al 1967a, b) and the organ is well developed in the most primitive living ant species Nothom.)'rmecia macrops (Taylor 1978) (see Fig. 2). In the course of our current comparative study of the internal and external anatomy of exocrine glands in ants, we discovered that the metapleural gland is absent or significantly reduced in several ant genera where such reduction had not been previously suspected. In addition we observed a widespread absence of the metapleural gland in males among ant species. Our survey is far from complete, even at the generic and tribal levels. -
Invasibility of Native Habitats by Argentine Ants, Linepithema Humile, in New Zealand

Ward1* and Richard J. Harris2 1School of Biological Sciences, Tamaki Campus, University of Auckland, Private Bag 92019, Auckland, New Zealand 2Landcare Research, P.O. Box 6, Nelson, New Zealand *Author for correspondence (E-mail: [email protected]) ____________________________________________________________________________________________________________________________________ Abstract: The Argentine ant, Linepithema humile, was found established in New Zealand in 1990. During summer 2001/2002 the spread of Argentine ants from urban environments into native habitats was investigated. During an initial large-scale survey around the northern cities of Auckland and Whangarei, Argentine ants were observed at 35 of 211 sites. Eight sites in Auckland were subsequently surveyed in greater detail to determine the extent of movement by Argentine ants into native habitats. The presence of Argentine ants was determined every 10 m along a total of 28 transects into native forest, scrub and mangrove habitats. Argentine ants moved up to 20 m into forest habitats. In habitats with more open canopy (mangrove and scrub), ants moved at least 30 m and 60 m, respectively. We predict that open habitats and relatively open canopy scrub environments in northern New Zealand are likely to be vulnerable to invasion, and to experience the highest densities and the greatest impacts of Argentine ants. Our preliminary data, coupled with data from other parts of the world suggests that intact indigenous forest in New Zealand will probably not be invaded. -

Caterino, Committee Chair Dr. Peter Adler Dr. Juan Antonio Baeza Dr. Joseph Parker ABSTRACT Secondary sexual characters (SSC) are traits present only in one sex, commonly on males, and different from the reproductive organs. These characters have evolved mainly through the action of Sexual Selection, the differential mating success of organisms of the same species. Males use SSC to challenge other males for access to females, while females use these traits as signals to choose mates with overall good. SSC can manifest as horns, tusks, enlarged appendages, spines, coloration, and body size. Sexually dimorphic traits are present in all major groups of animals, including Insects. Sexual selection and secondary sexual traits have been proposed to be drivers for speciation on hypothetical bases, but empirical evidence has proven to be inconclusive. -

Despite its abundance and ecological dominance, little is known of its species diversity and distribution throughout its range. Here, we describe the diversity and distribution of Anonychomyrma in the Australian Wet Tropics bioregion, where only two of the many putative species are described. We hypothesise that the genus in tropical Australia retains a preference for cool wet rainforests reminiscent of the Gondwanan forests that once dominated Australia, but now only exist in upland habitats of the Wet Tropics. Our study was based on extensive recent surveys across five subregions and along elevation and vertical (arboreal) gradients. We integrated genetic (CO1) data with morphology to recognise 22 species among our samples, 20 of which appeared to be undescribed.
