Hypoaspis muellerae Halliday 2005
No full textHypoaspis muellerae Halliday, 2005 (Figs 38–45) Hypoaspis muellerae Halliday, 2005: 32. Specimens examined. Five paratypes (ANIC 51-002833 – 51-002837) were examined by the first author from Australian National Insect Collection, Canberra (Australia), and each microslide containing one female labelled as: Hypoaspis muellerae Halliday, South Africa, Plettenberg Bay, 18 August 1994, Roadside picnic area, TK. Qin coll., Clover, cape weed, site 30–13. Halliday (2005) described Hypoaspis muellerae from Plettenberg Bay, South Africa. We have re-examined the paratypes of this species, and now take the opportunity to make some additions to the original description. In the description of this species (Halliday, 2005, Fig. 17) setae st4 are obviously present but that was an error, and in all the specimens we examined setae st4 were absent (Figs 39 & 41). The description did not mention the location of iv3, but they are located on the posterolateral angles of the sternal shield in all the specimens we examined (Fig. 41). This species shows some significant morphological character states typical of Laelaspisella: (1) dorsal shield hypertrichous and with at least 11–13 non-secretory slit-like lyrifissures (Figs 38 & 40); (2) metasternal setae st4 absent (Figs 39 & 41); (3) genitiventral shield large, broad and rounded posteriorly (Fig. 39); (4) iv3 located on posterolateral angles of sternal shield (Fig. 41); (5) internal malae densely fringed and with elongate threads (Fig. 42); (6) lateral margin of epistome smooth and anteriorly mucronated (Fig. 43); (7) palp tarsal claw with two tines (Fig. 44). However, it differs from the original concept of Laelaspisella as described by Marais & Loots (1969), because the dorsal cheliceral seta is present (Fig. 45).Published as part of Joharchi, Omid, Ramroodi, Sara & Halliday, Bruce, 2020, Review of the genus Pogonolaelaps Nemati & Gwiazdowicz (Acari: Laelapidae) with description of a new species from Iran, pp. 465-484 in Zootaxa 4820 (3) on pages 477-481, DOI: 10.11646/zootaxa.4820.3.3, http://zenodo.org/record/439805

We have re-examined the holotype of this species (Figs. 1–6). In the original description (Joharchi and Halliday 2011, Figs. 1–9), the peritrematal shield was not illustrated, but it is present in the holotype, it is free from the dorsal shield, and tapers to a point, just anteriorly to the peritreme apex (Fig. 6). Dorsal shield without distinct reticulate ornamentation over whole surface (except for sigillae and marginal areas in both podonotal and opisthonotal regions). The illustrations provided by Joharchi and Halliday (2011) did not show all segments of the legs, so we provide them here to clarify the identity of this species. Joharchi and Halliday (2011) stated that the tibia of the palp has 12 setae, but we now correct that to 14 setae, which is typical for Laelapidae.</p>Published as part of <i>Joharchi, Omid & Halliday, Bruce, 2020, Supplementary descriptions of thirteen species of soil mites (Mesostigmata: Laelapidae), pp. 23-42 in Persian Journal of Acarology 9 (1)</i> on page 24, DOI: 10.22073/pja.v9i1.58256, <a href="http://zenodo.org/record/4635118">http://zenodo.org/record/4635118</a>
Dawn and photoperiod sensing by phytochrome A
No full textIn plants, light receptors play a pivotal role in photoperiod sensing, enabling them to track seasonal progression. Photoperiod sensing arises from an interaction between the plant's endogenous circadian oscillator and external light cues. Here, we characterize the role of phytochrome A (phyA) in photoperiod sensing. Our metaanalysis of functional genomic datasets identified phyA as a principal regulator of morning-activated genes, specifically in short photoperiods. We demonstrate that PHYA expression is under the direct control of the PHYTOCHROME INTERACTING FACTOR transcription factors, PIF4 and PIF5. As a result, phyA protein accumulates during the night, especially in short photoperiods. At dawn, phyA activation by light results in a burst of gene expression, with consequences for physiological processes such as anthocyanin accumulation. The combination of complex regulation of PHYA transcript and the unique molecular properties of phyA protein make this pathway a sensitive detector of both dawn and photoperiod. © 2018 Proceedings of the National Academy of Sciences of the United States of America.

Halliday, William / interviewed by Spencer Fleury and Todd Chavez Oral History: William Halliday
No full textDr. William Halliday, medical surgeon and karst terrain authority, relates segments of his life story back to the development of his interest in karst and caving. Dr. Halliday recounts his involvement as a charter member of the National Speleological Society (NSS), founding several grottos, and the political activism in which he participated on their behalf. He describes a few of his international caving adventures, the difference between karst and pseudo-karst, and his impressions on whether there exists an attitudinal divide between geologists and amateur sport cavers. The interview ends with Dr. Halliday\u27s personal belief that Mars exploration should be pivotal in the future of karst research.
Interview conducted July 23, 2007 at the National Speleological Society convention in Marengo, Indiana
