Examining the links between spiritual struggles and symptoms of psychopathology in a national sample.

Abstract: The present study investigated the relationship between spiritual struggles and various types of psychopathology symptoms in individuals who had and had not suffered from a recent illness. Participants completed self-report measures of religious variables and symptoms of psychopathology. Spiritual struggles were assessed by a measure of negative religious coping. As predicted, negative religious coping was significantly linked to various forms of psychopathology, including anxiety, phobic anxiety, depression, paranoid ideation, obsessive-compulsiveness, and somatization, after controlling for demographic and religious variables. In addition, the relationship between negative religious coping and anxiety and phobic anxiety was stronger for individuals who had experienced a recent illness. These results have implications for assessments and interventions targeting spiritual struggles, especially in medical settings.

FeCycle: Attempting an iron biogeochemical budget from a mesoscale SF6 tracer experiment in unperturbed low iron waters

Abstract: [1] An improved knowledge of iron biogeochemistry is needed to better understand key controls on the functioning of high-nitrate low-chlorophyll (HNLC) oceanic regions. Iron budgets for HNLC waters have been constructed using data from disparate sources ranging from laboratory algal cultures to ocean physics. In summer 2003 we conducted FeCycle, a 10-day mesoscale tracer release in HNLC waters SE of New Zealand, and measured concurrently all sources (with the exception of aerosol deposition) to, sinks of iron from, and rates of iron recycling within, the surface mixed layer. A pelagic iron budget (timescale of days) indicated that oceanic supply terms (lateral advection and vertical diffusion) were relatively small compared to the main sink (downward particulate export). Remote sensing and terrestrial monitoring reveal 13 dust or wildfire events in Australia, prior to and during FeCycle, one of which may have deposited iron at the study location. However, iron deposition rates cannot be derived from such observations, illustrating the difficulties in closing iron budgets without quantification of episodic atmospheric supply. Despite the threefold uncertainties reported for rates of aerosol deposition (Duce et al., 1991), published atmospheric iron supply for the New Zealand region is ∼50-fold (i.e., 7- to 150-fold) greater than the oceanic iron supply measured in our budget, and thus was comparable (i.e., a third to threefold) to our estimates of downward export of particulate iron. During FeCycle, the fluxes due to short term (hours) biological iron uptake and regeneration were indicative of rapid recycling and were tenfold greater than for new iron (i.e. estimated atmospheric and measured oceanic supply), giving an “fe” ratio (uptake of new iron/uptake of new + regenerated iron) of 0.17 (i.e., a range of 0.06 to 0.51 due to uncertainties on aerosol iron supply), and an “Fe” ratio (biogenic Fe export/uptake of new + regenerated iron) of 0.09 (i.e., 0.03 to 0.24).

A habitat matrix conceptual model for stream periphyton

Abstract: In this paper we suggest a conceptual model for the evaluation of periphyton communities in unshaded temperate streams based on the primary habitat variables of flood disturbance, nutrient resource supply and invertebrate grazing. The core of this model is a classification of 35 periphyton taxa into four main functional groups based on the C-S-R life history strategies of Grime. Possible successional trajectories following system-wide disturbances under different nutrient supply regimes are also discussed. The interaction of disturbance and nutrient supply on species membership, productivity and accrual time results in a predicted gradient from low biomass in frequently disturbed, unenriched habitats to high biomass in infrequently disturbed, enriched habitats. This prediction is verified empirically using literature data. Herbivory can strongly modify such periphyton responses to disturbance and resource supply. However, these grazing effects could vary greatly depending on the dominant invertebrate grazer and their total abundance, which inturn, is also sensitive to changes in disturbance and nutrient resource supply. This interaction is also discussed. The conceptual model complements other more general habitat templet and dynamic equilibrium concepts in ecology.

The role of habitat in avian community composition: physiognomy or floristics?

Abstract: It has been proposed that within rather broad habitat types the distribution and abundance of bird species may be more closely associated with plant taxonomic composition than with the structure and configuration of the vegetation. Birds from a sample of eight representative grassland habitats in middle and western North America are consistent with this hypothesis. Over half (55%) of the variation in bird community composition was associated with floristic variation, but only a third (35%) was associated with physiognomy. Separating the interacting effects of floristics and physiognomy from each other served to accentuate the difference between them with respect to the avifauna. It is postulated that bird species/plant taxa associations, especially within similar habitat types, are mediated by the specific food resources that different plant taxa provide. Summary indices such as diversity measures obscure the taxonomic information content of plant or animal assemblages, and the use of such indices has likely impeded detection of the relationships described here.
