The role of territory choice mate choice and arrival date on breeding success in the Savi's warbler (Locustella luscinioides)

We investigated how territory quality, settlement date and morphometry affected several components of yearly breeding success of a Swiss population of Savi's Warblers Locustella luscinioides. Territories occupied by males differed from unoccupied sites of similar size and location by having higher and denser reeds, a more extensive straw litter, and a thicker cover of dead sedge leaves. Territories with these characteristics were the ones first chosen by males upon spring arrival. These males, however, did not differ in morphometry from those that arrived later. Availability of suitable nesting sites; rather than food availability, appears to be an important choice criterion for territories. Early arriving males had higher breeding success than late males because of a higher mating success and more successful clutches. The positive correlation between male breeding success and territory quality was thus mediated through their common dependence on occupancy date. Female breeding success decreased with the date of first-clutch laying, mainly because late-nesting females fledged fewer broods. Breeding success in either sex did not correlate with morphometry. Our results provide clear support for territory choice by males, but not for mate or territory choice by females, and show the crucial role played by individual settlement date on many aspects of the breeding cycle of both sexes. We propose a lottery model of mate choice. arriving females obtain the best available territories even without choosing mates or territories; since males occupy territories sequentially and in order of decreasing quality, the few unpaired males available at any moment also occupy the best available territories.

Appropriate management of special situations in Crohn's disease (upper gastro-intestinal; extra-intestinal manifestations; drug safety during pregnancy and breastfeeding): results of a multidisciplinary international expert panel-EPACT II

Introduction: High-grade evidence is lacking for most therapeutic decisions in Crohn's disease. Appropriateness criteria were developed for upper gastro-intestinal, extra-intestinal manifestations and drug safety during conception, pregnancy and breastfeeding in patients with Crohn's disease, to assist the physician in clinical decision making. Methods: The European Panel on the Appropriateness of Crohn's Disease Therapy (EPACT II), a multidisciplinary international European expert panel, rated clinical scenarios based on evidence from the published literature and panelists' own clinical expertise. Median ratings (on a 9-point scale) were stratified into three categories: appropriate (7-9), uncertain (4-6 with or without disagreement) and inappropriate (1-3). Experts were also asked to rank appropriate medications by priority. Results: Proton pump inhibitors, steroids, azathioprine/6-mercaptopurine and infliximab are appropriate for upper gastro-duodenal Crohn's disease; for stenosis, endoscopic balloon dilation is the first-tine therapy, although surgery is also appropriate. Ursodeoxycholic acid is the only appropriate treatment for primary sclerosing cholangitis. Infliximab is appropriate for Pyoderma gangrenosum, ankylosing spondylitis and uveitis, steroids for Pyoderma gangrenosum and ankylosing spondylitis, adalimumab for Pyoderma gangrenosum and ankylosing spondylitis, cyclosporine-A/tacrolimus for Pyoderma gangrenosum. Mesalamine, sulfasalazine, prednisone, azathioprine/6-mercaptopurine, ciprofloxacin, and probiotics, may be administered safety during pregnancy or for patients wishing to conceive, with the exception that mate patients considering conception should avoid sulfasalazine. Metronidazol is considered safe in the 2nd and 3rd trimesters whereas infliximab is rated safe in the 1st trimester but uncertain in the 2nd and 3rd trimesters. Methotrexate is always contraindicated at conception, during pregnancy or during breastfeeding, due to its known teratogenicity. Mesalamine, prednisone, probiotics and infliximab are considered safe during breastfeeding. Conclusion: EPACT II recommendations are freely available online (www.epact.ch). The validity of these criteria should now be tested by prospective evaluation. (C) 2009 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.

MVD Quarterly Report on Building Project, 1st Quarter, FY07

A quarterly report from the Iowa Department of Transportation regarding building project status.

Caracterização morfológica de espécies de Hemerobius Linnaeus, 1758 (Neuroptera, Hemerobiidae) associadas a cultivos de café (Coffea arabica L.), milho (Zea mays L.) e erva-mate (Ilex paraguariensis St. Hill.)

The predators were collected in mate crop in Cascavel and São Mateus do Sul, Paraná, Brazil and some other additional specimens in coffee and maize crops in Ribeirão Preto, São Paulo, Brazil. Illustrations obtained by SEM are given by the first time to the principal structures. Three species of Hemerobius were identified: H. bolivari Banks, 1910; H. domingensis Banks, 1941 and H. gaitoi Monserrat, 1996. H. domingensis is recorded for the first time to Brazil.

Comparação dos sistemas de cultivo nativo e adensado de erva mate, Ilex paraguariensis St. Hil., quanto à ocorrência e flutuação populacional de insetos

This research was carried out in order to compare the occurrence of insects in two maté cultivation systems, native and high tree density. It was performed from August/2000 to September/2001, in a private property in São Mateus do Sul county, in Paraná State, Brazil. Visual inspections of trees and light traps were used to evaluate insect populations in both areas. For Hedypathes betulinus (Klug) (Coleoptera, Cerambycidae), only six adults were observed in the dense area. Based on presence of sawdust at the basis of the trunk, it was obtained that the number of attacked trees did not surpass 11% in either area. For Gyropsylla spegazziniana (Lizer y Trelles) (Hemiptera, Psyllidae), the number of galls per tree was counted and it was observed that the population peak occurred from November to January. For Hylesia spp. (Lepidoptera, Saturniidae) and Thelosia camina Schaus (Lepidoptera, Eupterotidae), the presence of caterpillars on the trees was noticed from September to February, with the population peak in November and December. Adults of Hylesia spp. were more numerous in February and March. Two species that were not previously recorded for Brazil on maté were identified: Hylesia paulex Dognin (83%) and Hylesia remex Dyer (17%), collected with light traps. The maté caterpillar, T. camina was not collected with these traps. Nymphs and adults of Ceroplastes grandis Hempel (Hemiptera, Coccidae) were observed along the year on the branches, with population peak between April and June for the nymphs and from September to November for the adults. It should be considered that despite higher insect incidence in the dense area compared to the native area, the first presents higher yield, and that with a good pest management program the insect problems can be minimized.

NAPIS Report YTD 1st Quarter-4th Quarter 2007

INAPIS Title III Client Service Unit Report - INAPIS (National Aging Program Information System) Service Unit Report collects and reports service/performance data and related program management information to the federal and state government. This report shows the number of older Iowans who receive services and the number of units by service category from Title III funding of the Older Americans Act, the Administration on Aging (AoA) and limited state general fund dollars. Additionally, it shows the number of persons served by individual services and total "unduplicated" client count across all services. In other words, if you add the total number of clients from all services it is higher than the actual number of persons served across all services, because some people need and receive more than one service. (Please note: this is preliminary data, and may be subject to change.)

Title III-E Report YTD 1st Quarter-4th Quarter 2007

Family Caregiver Support Program (Title III-E) - The Administration on Aging (AoA) has determined that for Title III-E, the actual family caregiver is the client, not the older person receiving the services. Iowa NAPIS (National Aging Program Information System) collects and reports Title III-E service/performance data and related program management information to the federal and state government in a format like the other Title III services. The major shift in reporting relates to who is the client. As a result, this Title III-E Client/Service Unit Report shows the number of caregivers who receive services and the number of units by service category from the Title III-E funding of the Older Americans Act, the AoA, and limited state general fund dollars. Additionally, it shows the number of persons served by individual services and total "unduplicated" client count across all services. In other words, if you add the total number of clients (caregivers) from all services, it is higher than the actual number of persons served across all services because some people need and receive more than one service. (Please note: this is preliminary data, and may be subject to change.)

Flutuação populacional de Gyropsylla spegazziniana (Lizer y Trelles) (Hemiptera, Psyllidae) e de seus inimigos naturais em erva-mate no município de São Mateus do Sul, PR, Brasil

G. spegazziniana é considerada uma das principais pragas da cultura da erva mate, porém pouco se conhece sobre sua densidade populacional e de seus inimigos naturais. O objetivo do trabalho foi determinar a dinâmica populacional da praga e de seus inimigos naturais, visando definir o momento adequado para seu controle. A flutuação populacional foi avaliada mediante a instalação de 10 armadilhas Gyrotrap®, em uma área de 0,5 ha, em um erval situado em São Mateus do Sul, Pr, Brasil. Verificou-se a ocorrência de G. spegazziniana durante o ano todo, com um aumento populacional no início e meados da primavera; os picos foram observados entre outubro e abril. Para o levantamento dos inimigos naturais, foram realizadas coletas quinzenais diretamente nas erveiras, utilizando-se um funil de alumínio. Dentre os inimigos naturais associados à cultura, a maioria foram predadores e uma espécie de parasitóide, os quais apresentaram picos populacionais sincronizados com o da praga.

1st datings of ammonite-bearing Bajocian suites from Caucasus (Georgia) - K-Ar ages of volcanic hornblendes

Volcanic flows and tuffs interbedded with ammonite-bearing sediments directly correlatable with the stratotype section of the Bajocian stage have been dated for the first time within the Caucasus area. Three samples, each from a different section, allowed separation of well-preserved brown hornblende; these are considered reliable geochronometers in a region where subsequent volcanic activity occurred. The dated separates are V139: a volcanic layer probably near the base, V142 another layer near the top of the Lower Bajocian substage; V141 a boulder from a latest Bajocian volcanic conglomerate. From bottom to top, apparent ages at 173.5 +/- 2.6, 164.8 +/- 2.5 and 167.1 +/- 1.9 Ma (analytical uncertainty, 95% confidence level) respectively, can be calculated. The consistency of the results is obtained if the dated boulder is interpreted as derived from an underlying layer, The Bajocian-Bathonian boundary is much younger than commonly accepted and younger than 164 Ma.

1st radiometric dating of a paleontologically dated Bathonian level from Georgia (USSR) - Use of the cathodoluminescence for selection of suitable plagioclases

Jurassic volcanic formations interlayered with (ammonite-bearing) sediments are common in the Caucasus area; this situation is of interest for the numerical calibration of the poorly documented Jurassic portion of the time scale. However, following petrographic study on thin sections no whole-rocks can be considered reliable geochronometers due to subsequent alteration; from about 20 samples, two were selected for plagioclase dating; one (V134) is probably early Kimmeridgian in age; the other (V136) is probably located in the Lower Bathonian stage according to diagnostic ammonites. Cathodoluminescence (CTL) study has shown that sample V136 was similar to usual volcanic feldspars (blue to green colour); however, the lack of CTL of the V134 plagioclase is a character common to diagenetic feldspars; consequently, in spite of a good optical preservation, this geo-chronometer cannot give an age representative of the time of emplacement of the lava flow. We have combined CTL observation with microprobe analysis in order to document the poorly known CTL behaviour of volcanic feldspars; cations Ti4+ and Fe2+ play a major role in the CTL colour of plagioclases and are able to document the growing history of these feldspars ; phenocrysts are initially rich in Fe2+ (core of the crystals, green in colour), then richer in Ti toward the exterior; microcrysts are even richer in Ti (blue to bright blue). We have also observed that natural CTL colour was modified resulting from acid ``cleaning'' of the separated feldspars : the initial blue or green colour tends to change to yellow or violet, respectively, after acid treatment probably due to oxydation of Fe2+ toward Fe3+. X-ray and microprobe analyses both indicated that plagioclases from sample V134 was near the sodic end member (albite) suggesting a diagenetic origin in this andesitic basalt; In contrast, sample V136 contains a calcic plagioclase of common composition for a doleritic basalt. The K-Ar conventional technique was applied as a preliminary tool for radiometric analysis. The Kimmeridgian Na-plagioclase sample gave a ``rejuvenated'' (85 Ma) apparent age which confirms a late genesis for the separated plagioclase phase; this interpretation is based on CTL observation, X-ray analysis, and microprobe analysis ; these techniques are able to distinguish samples which have been submitted to diagenetic alteration from those which have not. An age consistent with the stratigraphic location has been obtained from sample V136. This age of 161 +/- 3 (2-sigma) Ma, is the first one available from a sample palaeontologically located with reasonable precision within the mid Jurassic time.

Effect of potassium fertilization on yield and nutrition of yerba mate (Ilex paraguariensis)

Yerba mate (Ilex paraguariensis) is a tree species native to the subtropical regions of South America, and is found in Brazil predominantly in the southern region. Despite the historical importance in this region, so far, studies on crop nutrition to improve yields are scarce. Thus, this study evaluated the effect of potassium rates on K soil availability, and the yield and nutritional status of yerba mate. The experiment was conducted in São Mateus do Sul, State of Paraná, on a Humox soil, where K2O rates of 0, 20, 40, 80, 160, and 320 kg ha-1 were tested on 7-year-old plantations. The experiment was harvested 24 months after installation by removing approximately 95 % of the canopy that had sprouted from the previous harvest. The soil was evaluated for K availability in the layers 0-10, 0-20, 10-20, and 20-40 cm. The plant parts leaf fresh matter (LM), twigs (TW), thick branches (BR) and commercial yerba mate (COYM), i.e., LM+TW, were analyzed. In addition, the relationship between fresh matter/dry matter (FM/DM) and K concentration in LM, AG and BR were evaluated. The fertilization increased K availability in all evaluated soil layers, indicating good mobility of the nutrient even at low rates. Yerba mate responded positively to increasing K2O rates with higher yields of all harvested components. The crop proved K-demanding, with a maximum COYM yield of 28.5 t ha-1, when 72 mg dm-3 K was available in the 0-20 cm layer. Yerba mate in the plant production stage requires soil K availability at medium to high level; in clayey soil with low K availability, a rate of 300 kg ha-1 K2O should be applied at 24 month intervals to obtain high yields. A leaf K concentration of 16.0 g ha-1 is suitable for yerba mate in the growth stage.

Mating order-dependent female mate choice in the polygynandrous common lizard Lacerta vivipara.

Recent studies indicate that directional female mate choice and order-dependent female mate choice importantly contribute to non-random mating patterns. In species where females prefer larger sized males, disentangling different hypotheses leading to non-random mating patterns is especially difficult, given that male size usually correlates with behaviours that may lead to non-random mating (e.g. size-dependent emergence from hibernation, male fighting ability). Here we investigate female mate choice and order-dependent female mate choice in the polygynandrous common lizard (Lacerta vivipara). By sequentially presenting males in random order to females, we exclude non-random mating patterns potentially arising due to intra-sexual selection (e.g. male-male competition), trait-dependent encounter probabilities, trait-dependent conspicuousness, or trait-dependent emergence from hibernation. To test for order-dependent female mate choice we investigate whether the previous mating history affects female choice. We show that body size and body condition of the male with which a female mated for the first time were bigger and better, respectively, than the average body size and body condition of the rejected males. There was a negative correlation between body sizes of first and second copulating males. This indicates that female mate choice is dependent on the previous mating history and it shows that the female's choice criteria are non-static, i.e. non-directional. Our study therefore suggests that context-dependent female mate choice may not only arise due to genotype-environment interactions, but also due to other female mating strategies, i.e. order-dependent mate choice. Thus context-dependent female mate choice might be more frequent than previously thought.
