Summary Dreschlera cactivora isolated from an imported collection of Cactaceae is described. A blossum rot of Hedyscype canterburgense caused by Penicillium lavendulum and a root-rot of Rhododendron root-stocks are noted. A leaf-spot of Arum neglectum caused by Ramularia ari is recorded. 相似文献

Summary The identity of a recent Scottish collection thought to be Boletopsis leucomelaena was examined with the help of molecular techniques. This poroid fungus proved to be a new species of Boletopsis differing from the European species occurring with Pinus sylvestris, which should continue to be called B. grisea. The new name Boletopsis peplexa is introduced for all the Scottish collections with Pinus sylvestris. 相似文献

Summary A male and female patient were admitted to the Poison Unit, Royal Infirmary, Edinburgh, suffering from poisoning caused by eating basidiocarps of Panaeolus subbalteatus (B. & Br.) Sacc. Those basidiocarps involved in the poisoning and later collections are described in full and pertinent ecological data etc. given. 相似文献

Abstract
The patterns of seasonal variation in the structure of a marine benthic microbial community were examined using phospholipid
fatty acid analysis (PLFA). Principal component analysis of PLFA profiles indicated a strong seasonal pattern dominated the
variance within the data set. Three functional groups of microorganisms (phototrophic microeukaryotes, and two groups of anaerobic
bacteria) were disproportionately abundant in the communities that mapped to either extreme of the first principle component.
Phototrophic microeukaryotes were most abundant and exhibited the greatest relative abundance during periods of cold water.
In contrast, the two functional groups of anaerobic bacteria showed the greatest relative abundance during times of warm water.
Differential responses by these groups, and macrofaunal deposit feeders, to light intensity and water temperature were offered
as the proximal causes of the observed patterns.

Climate change is anticipated to exacerbate the extinction risk of species whose persistence is already compromised by habitat loss, invasive species, disease, or other stressors. In coastal areas of the southeastern United States (USA), many imperiled vertebrates are vulnerable to hurricanes, which climate models predict to become more severe in the 21st century. Despite this escalating threat, explicit adaptation strategies that address hurricane threats, in particular, and climate change more generally, are largely underrepresented in recovery planning and implementation. We provide a basis for stronger emphasis on strategic planning for imperiled species facing the increasing threat of catastrophic hurricanes. Our reasoning comes from observations of short‐term environmental and biological impacts of Hurricane Michael, which impacted the Gulf Coast of the southeastern USA in October 2018. During this storm, St. Marks National Wildlife Refuge, located along the northern Gulf of Mexico's coast in the panhandle region of Florida, received storm surge that was 3.0–3.6 m (NAVD88) above sea level. Storm surge pushed sea water into some ephemeral freshwater ponds used for breeding by the federally threatened frosted flatwoods salamander (Ambystoma cingulatum). After the storm, specific conductance across all ponds measured varied from 80 to 23,100 µS/cm, compared to 75 to 445 µS/cm in spring 2018. For 17 overwashed wetlands that were measured in both spring and fall 2018, posthurricane conductance observations were, on average, more than 90 times higher than in the previous spring, setting the stage for varying population responses across this coastal landscape. Importantly, we found live individual flatwoods salamanders at both overwashed and non‐overwashed sites, although we cannot yet assess the demographic consequences of this storm. We outline actions that could be incorporated into climate adaptation strategies and recovery planning for imperiled species, like A. cingulatum, that are associated with freshwater coastal wetlands in hurricane‐prone regions. 相似文献

Summary In recent years, fungal conservation in Scotland has made substantial progress, particularly as a result of field surveys undertaken in support of the Biodiversity Action Plans developed for selected species. Results are presented from four recent surveys: (i) fungal diversity in conifer plantations, (ii) hydnoid (‘tooth’) fungi in coniferous forests, (iii) grassland fungi, (iv) fungal survey of the Mar Lodge Estate. These surveys have substantially improved knowledge of the conservation status of a number of threatened taxa, and have also provided insights into patterns of fungal diversity at a range of scales. The results indicate that some of the fungal communities of Scotland, such as those associated with unimproved grasslands, are of international conservation importance. The implications of the survey results for conservation management are discussed, and suggestions are made regarding priorities for future work. In particular, there is a need to provide conservation managers with guidance on how fungal conservation can be achieved in practice. 相似文献
