1. Studies in Lichens and Lichenicolous Fungi - No. 23: Notes on Appalachian taxa including newly reported disjunctions and multiple species new to North America

   https://doi.org/10.5962/p.388460  

   Lendemer, James C (January 2023, Opuscula philolichenum)

   Arthonia ligniariella is reported for the first time from eastern North America based on a collection growing on lignum in North Carolina, U.S.A. Biatora appalachensis, an Appalachian endemic, is shown to be widespread throughout the Appalachian Mountains, primarily at high elevations. The only report of Fellhanera parvula from North America (Tennessee, U.S.A.) is considered to be F. bouteillei. Fellhanera subtilis, previously reported in North America from the Pacific Northwest, is reported for the first time from eastern North America (southern Appalachian Mountains). Gyalideopsis mexicana, previously reported in North America from the Yukon, Canada and New Mexico, U.S.A. is newly reported from eastern North America (southern Appalachian Mountains, North Carolina, U.S.A.). Lepra ouahensis, a sorediate species with lichexanthone and stictic acid, is reported from disjunct areas of the southern Appalachian Mountains and the Southeastern Coastal Plain. Its distribution is compared to the lichexanthone producing chemotypes of L. trachythallina and Varicellaria velata. Rockefellera crossophylla, a rare species considered extinct in Pennsylvania, U.S.A. is reported to be extant in that state. Psoronactis dilleniana is newly reported from North America from high elevations of the central and southern Appalachian Mountains (North Carolina and Virginia U.S.A.). Xenonectriella streimannii is newly reported for North America based on a collection found growing on Anaptychia palmulata in Georgia, U.S.A.

2. First record of Caligus dussumieri Rangnekar, 1957 (Copepoda, Siphonostomatoida, Caligidae) from Malaysia, with notes on caligids found from Malaysia and on host-specificity of caligids on lutjanid fishes

   Ismail, Norshida; Nishida, Yusuke; Ohtsuka, Susumu; Boxshall, Geoff; Bernot, James P (February 2024, Biodiversity Data Journal)

   In total, 14 species ofCaligushave been reported from Malaysia. Amongst them, four species are reported from lutjanid fishes. Caligus dussumieriRangnekar, 1957 is reported from Malabar snapper,Lutjanus malabaricus, purchased from a local wet market in Terengganu, Peninsular Malaysia. This is the first record of this species in Malaysia and it is only the second species assigned to thebonito-group of the genusCaligusto be reported from Malaysia. A key to species of thebonito-group is presented herein. The list of caligids infecting lutjanid fishes and the geographical distributions plus the known hosts of members of thebonito-group ofCaligusare discussed.

3. Updates and Additions to the Lichen Checklist of Mount Mitchell State Park, North Carolina, with Conservation Proposals for Five Rare Species

   LaGreca, S; Phillips, L; Medeiros, I; Allen, J; Lendemer, J (July 2025, Castanea)

   A survey of the lichens of Mount Mitchell State Park, North Carolina, published in 2017, recovered 171 species and reported 27 historically reported taxa missing. Here we report 72 lichen taxa as new for the park—based on both recent and historical specimens—for a total of 243 total taxa reported for all time points. In addition, 13 of the 27 taxa reported missing for the park in the 2017 survey were rediscovered. Most of these were found by either investigating non-spruce-fir substrates, which was the focus of the most recent survey in 2016, or returning to localities where historical specimens had previously been collected and intensively searching for the species. A revised list of 27 taxa that have not been seen since at least the early 1970s is presented, nine of which belong to the speciose genus Cladonia. The updated checklist for the park contains a surprisingly high level of cyanolichen diversity, suggesting the impacts of pollution and invasive insects on the lichen biota of the park are not as severe as previously thought. Molecular data (nrITS) confirm that Parmelia neodiscordans is distinct from other species of Parmelia and suggest that Appalachian material identified as P. omphalodes may be conspecific with the eastern Asian species P. ‘fertilis B’. Lastly, five rare lichens recorded from the park (Alectoria fallacina, Hypotrachyna densirhizinata, Lobarina scrobiculata, Nephroma parile and Parmelia neodiscordans) are proposed for conservation at the state level.

4. Identifying high-impact invasive plants likely to shift into northern New England with climate change

   https://doi.org/10.1017/inp.2021.10  

   Coville, William; Griffin, Bridget J.; Bradley, Bethany A. (June 2021, Invasive Plant Science and Management)

   null (Ed.)

   Abstract Invasive plants are expanding their ranges due to climate change, creating new challenges for invasive species management. Early detection and rapid response could address some nascent invasions, but limited resources make it impossible to monitor for every range-shifting species. Here, we aimed to create a more focused watch list by evaluating the impacts of 87 plant species projected to shift into northern New England (the states of Maine, New Hampshire, and/or Vermont). We used the Environmental Impact Classification for Alien Taxa (EICAT) protocol to evaluate all ecological impacts reported in the scientific literature, scoring ecological impacts from 1 (minimal concern) to 4 (major) depending on the level of reported impact. For each species, we also recorded any reported impacts on socioeconomic systems (agriculture, human health, or economics) as “present.” We found 24 range-shifting species with impacts on ecological communities, of which 22 have reported impacts in ecosystems common to northern New England. Almost all of these species also had impacts on socioeconomic systems and were available for purchase at ornamental plant retailers or online. Thus, these species can be considered high risk to northern New England with climate change based on their large negative impacts and potential to arrive quickly with deliberate human introduction. Our study demonstrates the use of impact assessments for creating targeted priority lists for invasive species monitoring and management.

5. A new Lamellibrachia species and confirmed range extension for Lamellibrachia barhami (Siboglinidae, Annelida) from Costa Rica methane seeps

   https://doi.org/10.11646/zootaxa.4504.1.1  

   MCCOWIN, MARINA F.; ROUSE, GREG W. (October 2018, Zootaxa)

   Lamellibrachia Webb, 1969 has eight currently recognized species reported from chemosynthetic environments in the Pacific, Atlantic, and Mediterranean. Of these, Lamellibrachia barhami Webb, 1969 has been reported in the eastern Pacific from Canada to Costa Rica. In this study, phylogenetic analyses of Lamellibrachia tubeworms sampled from the Costa Rica margin confirm the large geographic range of L. barhami and reveal a new Lamellibrachia species from a single methane seep between 999 and 1,040 meters. Lamellibrachia donwalshi sp. nov. differs genetically and morphologically from all congeneric species. Despite its geographic proximity to the eastern Pacific L. barhami, L. donwalshi sp. nov. formed a clade with Atlantic and Mediterranean Lamellibrachia species. This suggests a vicariant event may have occurred after an Atlantic radiation of Lamellibrachia.
