Analysis of a species/instars/characters table: a theoretical survey on the use of chaetotaxy in ontophylogenetic studies Naturalis
Nayrolles, Pierre.
Phylogenetic studies on several groups of arthropods, such as Acari (mites) or Collembola (springtails), make wide use of chaetotaxy. Chaetotaxic characters, besides being morphological features (setal shape), often have a binary nature, that is presence vs. absence. A seta can be variable in a population, and one may attribute a presence probability to this seta. In fact, the presence probability should be defined for each instar. One might think that a variable seta corresponds to a polymorphism (e.g., two or more alleles in a population); in fact, setal variability should be regarded as the result of a propensity intrinsic to individuals, i.e., a potentiality being expressed at random among specimens. The phenomenon known as lateral inhibition explains...

Biological vulnerability in the Elqui Valley (Coquimbo Region, Chile) to economically important arthropods Ciencia e Investigación Agraria
Pizarro-Araya,Jaime; Cepeda-Pizarro,Jorge; Barriga,Juan E; Bodini,Andrés.
Current climate conditions in north-central Chile (25057'-32013'S,71043'-68°16'W)are characterized by increasing temperatures and decreasing rainfall. Global warming is expected to alter the hydrology and ecoclimatic characteristics of north-central basins with multiple effects, including changes in plant and arthropod phenology and biodiversity. Among these basins, the Elqui Valley (29°50'S, 70°52'W) stands out for its large population and the economic importance of tourism and agriculture. The taxonomic composition of agriculturally and medically important arthropods was studied in three locations in the Elqui Valley by manual capture of specimens and interviews with farmers, agricultural workers, and local leaders. Out of a total of 145 species of...

Effects of no tillage on the abundance and diversity of soil and olive tree canopy arthropods. IPB - Escola Superior Agrária
Lousão, C.; Bento, Albino; Campos, M.; Ruano, F.; Pereira, J.A..
Soil tillage is a traditional practice in the olive groves of Trás-os-Montes region (Northeast of Portugal) where the soil is maintained without any vegetal cover. However, this agronomic practice may have dangerous environmental effects of several orders. In this way, with the present work we aimed to contribute for the knowledge about the effect of two soil management practices in the olive grove (traditional tillage in comparison to no tillage) on the arthropods abundance and diversity of the olive grove soil and the olive tree canopy with special reference to Formicidae family. The work was developed between April and October of 2004, in two continuous plots submitted to the following agronomical practices: one plot submitted to frequent tillage to...

Improved SAS codes for life table analysis of arthropod populations. Repositório Alice
MAIA, A. de H. N.; LUIZ, A. J. B.; PERVEZ, A..
Abstract: Fertility life table (FLT) analysis of arthropod populations can capture chronicle sub lethal effects not detected by acute survival assays (MARINHO-PRADO, 2011; NASCIMENTO et al., 1998; NARDO et al (2001) LIU et al, 2005; LUMBIERRES et al, 2004). Inference on FLT parameters requires the use of computational methods to estimate the variance of demographic summary measures derived from information of survival and fertility of the arthropod populations under study. Jackknife-based software available for life table analysis (HULTING et al, 1990 ; MAIA et al, 2000) were developed for analyzing qualitative treatments, but such approach is frequently misused for contrasting levels of quantitative factors (GANJISAFFAR et al., 2011; PAKYARI et al., 2011;...

New and rare Nepticulidae in the Netherlands (Lepidoptera) Naturalis
Nieukerken, E.J. van.
Eleven species of Nepticulidae are recorded from the Netherlands for the first time. Eight of these have been collected as larvae during recent field work: Ecroedernia hannoverella (Glitz), E. nlediofasciella (Haworth), E. spirzosella (Joannis). E. arcz~arella (Herrich- Schaffer). Trifurcula cryptella (Stainton), Stigmella aeneofusciella (Herrich-Schaffer). S. poterii (Stainton), and S. crataegella Klimesch. On the basis of old collection material E. longicaudella Klimesch, E. bradfordi Emmet and S. svenssoni (Johansson) can be added to the list. A single specimen of E. bradfordi appears to be only the second one known. Some notes on rare species are given. S. regiella (Frey) is recorded for the first time from Belgium.

Puyehue Cordón -Caulle: post-eruption analysis of changes in stream benthic fauna of Patagonia Ecología austral
Lallement,Mailén Elizabeth; Juárez,Santiago Martín; Macchi,Patricio Jorge; Vigliano,Pablo Horacio.
Volcanic eruptions are natural phenomena with the most diverse and varied consequences, and have important effects on both terrestrial and aquatic environments. On June 4th, 2011 the volcanic Puyehue Cordón-Caulle complex (2.236 masl, 40º 32´ S-72º 2´ W, Chile) erupted explosively ejecting on the first day, 950 million metric tons of ashes into the atmosphere. Due to predominant westerly winds, 24 million hectares of Argentinian Patagonia were covered by the ashfall. We studied three streams in northwestern Patagonia in order to explore the ash fall impact and possible recovery processes in water quality and macroinvertebrate communities. We selected three streams representing maximum, intermediate and minimum ash deposition levels. For each stream, we...

Taxonomy and distribution of the Trifurcula (Glaucolepis) raikhonae group (Lepidoptera: Nepticulidae) Naturalis
Nieukerken, E.J. van; Purplesis, R..
Trifurcula (Glaucolepis) melanoptera sp. n. is described from southern Europe, where it is widespread. It is closely related to the Central Asian T. (Glaucolepis) raikhonae Puplesis, which is redescribed. Together they form the raikhonae species group. Sinopticula Yang is here synonymized with Glaucolepis Braun, its only species S. sinica Yang is tentatively regarded as closely related, if not conspecific with T. raikhonae. The distribution is mapped. On the basis of recent Chinese findings the larvae are assumed to be gall-makers on Prunus branches. Some phylogenetic and biogeographic remarks are given.

Patchai Souksai; Yupa Hanboonsong.
The research studies an arthropod community in upland rice ecosystem at farmers’ field in Ban Had District, Khon Kaen Province, Northeast Thailand, was conducted during May to October 2011. Samples were collected using light traps, yellow sticky traps, sweep nets and visual observation methods. A total of 7,195 individual arthropods from 160 species were recorded in this study. Among the sampling methods, 140 species were recorded using light trap, followed by 108, 58 and 30 species collected by using yellow sticky trap, sweep net and visual observation, respectively. The arthropod community of this studies constituted of four guilds as phytophagous, predator, parasitoid and scavenger. The predator (60.93 % of total individuals and 47.17% of total species)...
