Micas are commonly used in Ar-40/Ar-39 thermochronological studies of variably deformed rocks yet the physical basis by which deformation may affect radiogenic argon retention in mica is poorly constrained. This study examines the relationship between deformation and deformation-induced microstructures on radiogenic argon retention in muscovite, A combination of furnace step-heating and high-spatial resolution in situ UV-laser ablation Ar-40/Ar-39 analyses are reported for deformed muscovites sampled from a granitic pegmatite vein within the Siviez-Mischabel Nappe, western Swiss Alps (Penninic domain, Brianconnais unit). The pegmatite forms part of the Variscan (similar to 350 Ma) Alpine basement and exhibits a prominent Alpine S-C fabric including numerous mica `fish' that developed under greenschist facies metamorphic conditions, during the dominant Tertiary Alpine tectonic phase of nappe emplacement. Furnace step-heating of milligram quantities of separated muscovite grains yields an Ar-40/Ar-39 age spectrum with two distinct staircase segments but without any statistical plateau, consistent with a previous study from the same area. A single (3 X 5 mm) muscovite porphyroclast (fish) was investigated by in situ UV-laser ablation. A histogram plot of 170 individual Ar-40/Ar-39 UV-laser ablation ages exhibit a range from 115 to 387 Ma with modes at approximately 340 and 260 Ma. A variogram statistical treatment of the (40)Ad/Ar-39 results reveals ages correlated with two directions; a highly correlated direction at 310 degrees and a lesser correlation at 0 degrees relative to the sense of shearing. Using the highly correlated direction a statistically generated (Kriging method) age contour map of the Ar-40/Ar-39 data reveals a series of elongated contours subparallel to the C-surfaces which where formed during Tertiary nappe emplacement. Similar data distributions and slightly younger apparent ages are recognized in a smaller mica fish. The observed intragrain age variations are interpreted to reflect the partial loss of radiogenic argon during Alpine (similar to 35 Ma) greenschist facies metamorphism. One-dirnensional diffusion modelling results are consistent with the idea that the zones of youngest apparent age represent incipient shear band development within the mica porphyroclasts, thus providing a network of fast diffusion pathways. During Alpine greenschist facies metamorphism the incipient shear bands enhanced the intragrain loss of radiogenic argon. The structurally controlled intragrain age variations observed in this investigation imply that deformation has a direct control on the effective length scale for argon diffusion, which is consistent with the heterogeneous nature of deformation.

Ectoparasites are common in most bird species, but experimental evidence of their effects on life-history traits is scarce. We investigated experimentally the effects of the hematophagous hen flea (Ceratophyllus gallinae) on timing of reproduction, nest-site choice, nest desertion, clutch size, and hatching success in the great tit (Parus major). When great tits were offered a choice on their territory between an infested and a parasite-free nest-box, they chose the one without parasites. When there was no choice, the great tits in a territory containing an infested nest-box delayed laying the clutch by 11 days as compared with the birds that were offered a parasite-free nesting opportunity. The finding that there was no difference in phenotypic traits related to dominance between the birds nesting in infested boxes and birds nesting in parasite-free boxes suggests that the delay is not imposed by social dominance. Nest desertion between laying and shortly after hatching was significandy higher in infested nests. There was no difference between infested and parasite-free nests in clutch size, but hatching success and hence brood size at hatching were significantly smaller in infested nests. Nest-box studies of great tits have been seminal in the development of evolutionary, ecological, and behavioral theory, but recently a polemic has arisen in the literature about the validity of the conclusions drawn from nest-box studies where the naturally occurring, detrimental ectoparasites are eliminated by the routine removal of old nests between breeding seasons. Our study suggests that this criticism is valid and that the evaluation of the effects of ectoparasites may improve our understanding of behavioral traits, life-history traits, or population dynamics

Os ecossistemas coralinos possuem grande importância ecológica, assim como são cruciais para a cultura, e desenvolvimento socio-económico de um grande número de países com ecossistemas costeiros. Em Cabo Verde os corais ou comunidades relacionadas são pouco conhecidos por conseguinte não se conhece a dimensão da sua importância ecológica e socio-económica. Este estudo, enquadrado no Trabalho Final do Curso de Bacharelato em Biologia Marinha e Pescas ministrado no ISECMAR, tem por objectivos a caracterização das comunidades coralinas das zonas de Salamansa e Baía das Gatas (zona balnear e Farol) bem como a avaliação das actividades antropogénicas nessas zonas. Uma descrição preliminar das zonas foi efectuada, seguida da aplicação de métodos de estimativa de cobertura bentonica, e de censo de peixes e invertebrados. Ainda se efectuou a medição de parâmetros ambientais como sedimentos em suspensão e temperatura. As percentagens de cobertura, e os índices de diversidade e riqueza para cada praia foram calculadas; adicionalmente se efectuaram Análises Cluster para visualização de eventuais semelhanças entre as zonas. Durante 32 horas de mergulho correspondentes a 2000 m de transectos, se identificaram cerca de 50 espécies de peixes, corais e outros invertebrados. Na zona balnear da Baía foi registrada o maior nível de impacto antropogénico geral, enquanto que, na zona de Salamansa se registraram os maiores índices de diversidade. Conclui-se que as comunidades estudadas possuem várias espécies com importância ecológica e comercial. Recomendam-se estudos socio-económicos e ecológicos para se aprofundar os conhecimentos nesses ecossistemas de forma a propor medidas de gestão e conservação eficientes. Recomendam-se também estudos similares a este mas com mais abrangência temporal e espacial de forma a seguir a evolução da biodiversidade das comunidades coralinas no tempo e em outras áreas geográficas significativas em termos de corais em Cabo Verde.

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.)

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.

OBJECTIVE: In order to improve the quality of our Emergency Medical Services (EMS), to raise bystander cardiopulmonary resuscitation rates and thereby meet what is becoming a universal standard in terms of quality of emergency services, we decided to implement systematic dispatcher-assisted or telephone-CPR (T-CPR) in our medical dispatch center, a non-Advanced Medical Priority Dispatch System. The aim of this article is to describe the implementation process, costs and results following the introduction of this new "quality" procedure. METHODS: This was a prospective study. Over an 8-week period, our EMS dispatchers were given new procedures to provide T-CPR. We then collected data on all non-traumatic cardiac arrests within our state (Vaud, Switzerland) for the following 12months. For each event, the dispatchers had to record in writing the reason they either ruled out cardiac arrest (CA) or did not propose T-CPR in the event they did suspect CA. All emergency call recordings were reviewed by the medical director of the EMS. The analysis of the recordings and the dispatchers' written explanations were then compared. RESULTS: During the 12-month study period, a total of 497 patients (both adults and children) were identified as having a non-traumatic cardiac arrest. Out of this total, 203 cases were excluded and 294 cases were eligible for T-CPR. Out of these eligible cases, dispatchers proposed T-CPR on 202 occasions (or 69% of eligible cases). They also erroneously proposed T-CPR on 17 occasions when a CA was wrongly identified (false positive). This represents 7.8% of all T-CPR. No costs were incurred to implement our study protocol and procedures. CONCLUSIONS: This study demonstrates it is possible, using a brief campaign of sensitization but without any specific training, to implement systematic dispatcher-assisted cardiopulmonary resuscitation in a non-Advanced Medical Priority Dispatch System such as our EMS that had no prior experience with systematic T-CPR. The results in terms of T-CPR delivery rate and false positive are similar to those found in previous studies. We found our results satisfying the given short time frame of this study. Our results demonstrate that it is possible to improve the quality of emergency services at moderate or even no additional costs and this should be of interest to all EMS that do not presently benefit from using T-CPR procedures. EMS that currently do not offer T-CPR should consider implementing this technique as soon as possible, and we expect our experience may provide answers to those planning to incorporate T-CPR in their daily practice.

Although evidence is accumulating that mothers can transfer antibodies to their offspring, little is known about the consequences of such a transfer to the offspring immune system. Because maternal antibodies are effective only during a short period of time after their transfer to offspring, one hypothesis is that maternal antibodies provides a transitory antigen-specific protection to offspring, thus lessening the need for offspring to mount their own humoral immune response towards these specific antigens. In birds, this scenario predicts that offspring immune response towards a specific antigen is inhibited to a larger extent in hatchlings than in older nestlings. We tested this hypothesis in tawny owls Strix aluco by cross-fostering clutches between nests and then challenging siblings with a vaccine either two times (at 4- and 11-d-old) or only one time at 11-d-old to compare the strength of the humoral response between nestlings born from mothers with naturally high and low levels of antibodies against this vaccine. Because maternal antibodies are expected to be effective only during a short period of time after hatching, we predict that maternal antibodies should inhibit the immune response of nestlings vaccinated from the fourth day after hatching more than in nestlings vaccinated only at a later age. As expected, the inhibitory effect of maternal antibodies was stronger in nestlings vaccinated soon after hatching than in siblings injected at a later age. Therefore, in wild avian populations pre-hatching maternal effects may confer offspring with a transitory immune protection in the first days following hatching.
