{"title":"Taxonomic revision of kelp species with rhizome-like holdfast, Laminaria longipes Bory and Laminaria repens Ruprecht, from Russian Far Eastern seas","authors":"A. Klimova, T. Klochkova, N.

Lamouroux species from the northern Pacific region. In the references, two different Laminaria species were recorded under the same name, Laminaria longipes Bory, due to errors in the labeling of authentic herbarium specimens, a very brief description, confusion of protologues, and the absence of type specimens. One of them, inhabiting the northern Atlantic Ocean, has rhizoids, whereas the second one from the Pacific Ocean has holdfast with rhizomes. The latter species was described by Ruprecht (1850) as Laminaria repens Ruprecht, however, due to various reasons this name was not scientifically accepted and in 19th century, this kelp species has been named differently, until the name L. longipes was universally accepted. None of its previous names were typified. We found original specimens collected in the 18th and 19th centuries that were used to describe these species, designated lectotypes and specified synonyms. We propose to return the name L. repens for the Pacific Laminaria species with rhizomes. Based on molecular- phylogenetic data of our specimens, we confirmed its validity and difference from another species with rhizomes distributed in the Pacific North America, L. sinclairii (Harvey ex JD Hooker & Harvey) Farlow, Anderson & Eaton. We also discuss developmental biology and ecology of L. repens from the Russian Far East, provide data on the geographical distribution of all known forms of this species and show that their areas, except for the Middle Kurile Islands, where they have been known so far, cover almost the entire distribution of this species.","PeriodicalId":37724,"journal":{"name":"Botanica Pacifica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67441010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cypripedium macranthos plants dominated the most of the sympatric populations. Vegetation surveys were performed in all localities, and the collected data were analyzed using the IBIS software. We applied the phytoindication scales elaborated by Tsatsenkin and his colleagues for ecological indicator value analysis. The Cypripedium populations were characterized by high floristic diversity of their habitats; however, all of them were found in areas where both canopy density and ground cover were low. In the most of the separated populations, ontogenetic spectra of Cypripedium species corresponded to the base spectrum with a predominance of the adult vegetative and reproductive shoots.","PeriodicalId":37724,"journal":{"name":"Botanica Pacifica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135319599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An accomplished botanist, he was also a programmer and a teacher. One of his many impressive features was his universality. Indeed, he was interested in a vast range of things, and his professional scope accordingly tended to be universal: for example, as a taxonomist, he studied a few groups of plants, but, unlike almost any taxonomist today (and like Linnaeus), he was keenly interested in the global system of life, and had his own opinion about how it should look like. Alexey was born and grew up in Moscow. He graduated from the Department of Higher Plants, Faculty of Biology, Lomonosov Moscow State University, in 1990. In 1998, he defended his candidate of sciences (PhD) thesis on taxonomy of the genera Plantago L. and Psyllium Mill. (Plantaginaceae) in European Russia and adjacent areas. Alexey’s thesis was supervised by Professor Vadim Nikolayevich Tikhomirov, who at that time was the head of the Department of Higher Plants. Having spent some years after his PhD in Moscow with no success in getting a research or teaching position at the University, in 2002–2003, he moved for a year to Kew Gardens, United Kingdom, then briefly returned to his hometown, and finally emigrated to the United States in 2006. He worked first at the university of another, much smaller, Moscow (Idaho), then in Woods Hole, Massachusetts, and then in Minot, North Dakota, where he got his tenure. However, restless as he was, in 2019, Alexey left the USA for a temporary position at Kyoto University, Japan. Kyoto was his last place of residence. During his last few years, he travelled all around Japan, from Hokkaido to Okinawa, but mainly lived in the Old Capital. Alexey dedicated much of his time to education. He was a long-time member of the organising committee of the most informal of Russian biology contests for school students, the School Biology Olympics at Moscow State University. He taught at Moscow South-West High School No. 1543 (1992 – 2006), where he established a system of scientific projects for children of the specialised biology class; both the class and the system survived to this day. Alexey also taught in each of the several universities where he worked. Additionally, he recorded a lot of short educational videos for YouTube, and even during the last evening of his life he was preparing for an online lecture for students of Moscow University. Alexey was also into programming and considerably helped to develop and popularise the R software environment, which is widely used among researchers worldwide. Alexey published a series of manuals on employment of this programming language in biological studies. Alexey travelled across the world to study the flora of all its regions. One of his most impressive accomplishments was the re-discovery (together with his daughter, Ekaterina) of the poorly known plant Haptanthus Goldberg & C.

It is supposed to be absent in eudicots, but recent data indicate that at least genus Curio is an exception. Unlike monocots, the forerunner tips in this genus become unifacial without activity of the adaxial meristem. The scrutinized morphological and anatomical investigation revealed that precocious differentiation and unifacial structure which are widely used in identifying the forerunner tip are necessary but insufficient criteria of the structure concerned. Two additional criteria for recognition of the forerunner tip are proposed, viz. the forerunner tip takes significant part of the upper leaf zone immediately after the completion of its development and it remains distinguishable at all subsequent stages of leaf morphogenesis.","PeriodicalId":37724,"journal":{"name":"Botanica Pacifica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67440357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Populations of A. sachalinensis of northern Sakhalin originated from A. nephrolepis about 300 ka BP. Populations of central Sakhalin were formed, probably, as a result of mixing of populations of northern and southern Sakhalin during the late glacial (about 18 ka BP).
