Ground beetles and rove beetles be associated with temporary ponds in England

To date, research on the ecology and conservation of wetland invertebrates has concentrated overwhelmingly on fully aquatic organisms. Many of these spend part of their life-cycle in adjacent terrestrial habitats, either as pupae (water beetles) or as adults (mayflies, dragonflies, stoneflies, caddisflies and Diptera or true-flies). However, wetland specialist species also occur among several families of terrestrial insects (Williams & Feltmate 1992) that complete their whole life-cycle in the riparian zone or on emergent vegetation. There are 441 terrestrial invertebrate species which characteristically occur in riparian habitats along British rivers. Most of these species belong to two families of predatory beetles: the ground beetles (Carabidae) and the rove beetles (Staphylinidae). This paper describes the diversity of ground and rove beetles around ponds, summarises life-histories, hibernation strategies, and morphological and behavioural adaptions

The semi-aquatic habitats of terrestial Coleoptera in a lowland river floodplain

PhD Thesis281 species of terrestrial ground-living beetles were recorded from 69 riparian and wetland sites in the floodplain of the lowland River Soar, England. Differences in species composition between pitfall trapped and timed hand-collected samples were smaller than those attributable to environmental and seasonal factors. Detrended Correspondence Analysis consistently ranked all sites against seasonal variations between April and June and floodplain sites against annual variations. DCA axis 1 scores were slightly better correlated with important environmental variables at the ecohabitat (<5Om) scale rather than the microhabitat scale. Canonical Correspondence Analysis detected assemblage responses to flooding disturbance and grazing pressure along the main channel as well as to water level stability in the floodplain. A conceptual model of floodplain land-use and river management postulated a dynamic equilibrium between flooding disturbances and vegetational succession, producing geomorphic and vegetational structures which serve as semi-aquatic habitats for terrestrial beetle assemblages with appropriate species traits. Impoundment for navigation affects assemblages by modifying the severity of flooding disturbance. The effects of grazing pressure resemble flooding disturbance. The short-term (<5yr) impact of bank regrading was explained by differences in severity, predictability and frequency compared to the beetles' generation length. Evenness and species richness were affected only by flooding and grazing disturbance. This response was not predicted by the intermediate disturbance hypothesis because the frequencies of flooding and grazing disturbances in the Soar valley are not appropriate to the hypothesis, which more closely relates to disturbance by bank regrading. In comparison to diversity indices, a rarity index was much less sensitive to environmental factors than species diversity indices and more robust against seasonal and yearly fluctuations. Consequently, it has more potential for use in site quality assessment

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

Proceedings of the 3rd Biennial Conference of the Society for Implementation Research Collaboration (SIRC) 2015: advancing efficient methodologies through community partnerships and team science

It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventionsi do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort to advance the innovation and rigor of implementation research and is uniquely focused on bringing together researchers and stakeholders committed to evaluating the implementation of complex evidence-based behavioral health interventions. Through its diverse activities and membership, SIRC aims to foster the promise of implementation research to better serve the behavioral health needs of the population by identifying rigorous, relevant, and efficient strategies that successfully transfer scientific evidence to clinical knowledge for use in real world settings [3]. SIRC began as a National Institute of Mental Health (NIMH)-funded conference series in 2010 (previously titled the “Seattle Implementation Research Conference”; $150,000 USD for 3 conferences in 2011, 2013, and 2015) with the recognition that there were multiple researchers and stakeholdersi working in parallel on innovative implementation science projects in behavioral health, but that formal channels for communicating and collaborating with one another were relatively unavailable. There was a significant need for a forum within which implementation researchers and stakeholders could learn from one another, refine approaches to science and practice, and develop an implementation research agenda using common measures, methods, and research principles to improve both the frequency and quality with which behavioral health treatment implementation is evaluated. SIRC’s membership growth is a testament to this identified need with more than 1000 members from 2011 to the present.ii SIRC’s primary objectives are to: (1) foster communication and collaboration across diverse groups, including implementation researchers, intermediariesi, as well as community stakeholders (SIRC uses the term “EBP champions” for these groups) – and to do so across multiple career levels (e.g., students, early career faculty, established investigators); and (2) enhance and disseminate rigorous measures and methodologies for implementing EBPs and evaluating EBP implementation efforts. These objectives are well aligned with Glasgow and colleagues’ [4] five core tenets deemed critical for advancing implementation science: collaboration, efficiency and speed, rigor and relevance, improved capacity, and cumulative knowledge. SIRC advances these objectives and tenets through in-person conferences, which bring together multidisciplinary implementation researchers and those implementing evidence-based behavioral health interventions in the community to share their work and create professional connections and collaborations

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M&gt;70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0&lt;e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

All records to date of this species come from the Okavango River system in Botswana and Namibia, where it appears to be the most frequently collected species of Acylophorus. Specimens were mainly obtained by sieving marsh litter, but a few specimens were collected by splashing riverbanks. Comparative notes. This species can be distinguished from both A. salifi and A. lomaensis by the less transverse pronotum, the more slender last segment of the maxillary palpi and, above all, by the form of the male genitalia. In addition, it is larger and darker than A. lomaensis. Populations of A. salifi occurring along the Okavango appear to be of the typical colour form (mainly black with reddish elytra), so colour may be an additional character that is useful for distinguishing A. acufer and A. salifi in the field. Etymology. This specific name is a noun in apposition meaning “bearer of needles”, a reference to the extraordinary shape of the parameres.Published as part of Lott, Derek A., 2012, Further studies of African Acylophorus Nordmann (Coleoptera: Staphylinidae: Staphylininae), pp. 39-52 in Zootaxa 3168 on page 49, DOI: 10.5281/zenodo.27978

Acylophorus makhoreae Lott, new species

Acylophorus makhoreae Lott, new species (Figs 8, 38, 58, 84, 116) Description. Length 7mm. Body colour very variable ranging from pale brown to black. Pronotum yellow to red-brown with a dark, diffuse mark covering the disc and sometimes suffused almost to the edges. Abdomen iridescent when dark. Appendages similarly variable in colour, but the terminal segment of the maxillary palpi is always darker than the penultimate segment. Head of average size (pronotum 1.75x wider than head), more or less as long as wide with rounded temples not very evident (Fig. 8). Pigmented area of head extending well in front of antennal insertion. Micropunctures extending over much of head, but very sparse away from the front of the head and next to the eyes. Dense short pubescence behind eyes. Two pairs of interocular setae arising from foveate punctures much closer to eyes than each other. Only four postocular setae visible from above on each side. Underside of head sparsely pubescent, depressed at base with gular sutures separate, but very proximate toward base. Right mandible with one sharp median tooth; left mandible lacking sharp tooth (Fig. 38). Maxillary palpi with terminal segment densely pubescent, with rounded angle on outer margin, asymmetric and less elongate than A. orientalis, longer than glabrous penultimate segment which is slightly elongate (Fig. 58). First segment of antenna as long as next five. Segments I to IV elongate, VII to XI transverse (Fig. 84). Pronotum only slightly transverse (1.1x wider than long) with rounded sides and widest in basal half. Shining with no micro-punctures. Dorsal, lateral and marginal setae shorter than in A. orientalis. Elytra transverse (1.7x wider than long) with pubescence arising from asperate punctures. Apical fringe of bristles longer than the hairs on the rest of the elytra. Abdominal tergites with evenly spaced, relatively sparse asperate punctures. Paramere bilobed, each lobe fairly flat, at least toward apex, pegs concentrated in dense mass at apex (Fig. 116). Median lobe longer than paramere with truncate apex. Type material.

I have also seen a female specimen collected at “ 8,000 ” feet from the Djem-Djem Forest to the west of Addis Ababa that may belong to this species. Most of the specimens were collected along streams. Comparative notes. Fairly distinct within the A. orientalis species group by virtue of the position of the antennal insertion, the broader, more asymmetric terminal segment of the maxillary palpi and the more transverse medial antennal segments. The form of the aedeagus and the arrangement of medial teeth on the mandibles are also useful characters. Etymology. Makhore was a legendary queen, who founded the kingdom of Jimma in the area where many of the type specimens were collected. The species name is the genitive case of a Latinised version of her name. Discussion. A. makhoreae has been placed in the A. orientalis group, because it lacks dense micropunctures on the head and pronotum. However, the form of the maxillary palpi, the mandibles and the aedeagus and the position of the antennal insertion point all suggest that it may be more closely related to some of the species in the A. densipennis group.Published as part of Lott, Derek A., 2010, The species of Acylophorus Nordmann (Coleoptera: Staphylinidae: Staphylininae) in continental sub-Saharan Africa, pp. 1-51 in Zootaxa 2402 on page 15, DOI: 10.5281/zenodo.27590
