Algal Taxonomy

A revised checklist of marine benthic algae of the Commander Islands (Russian Pacific) is presented. It is based on the authors’ field collections. The list of algae of the area totals to 187 species (36 Chlorophyta, 38 Ochrophyta, class Phaeophyceae, and 113 Rhodophyta) of these 44 species (9 Chlorophyta, 8 Ochrophyta, class Phaeophyceae, and 27 Rhodophyta) are added to the previous checklists (Selivanova and Zhigadlova, 1997). We also confirm the presence of 5 species on the Islands that were absent in our earlier material but were recorded by other authors (Phycodrys amchitkensis, Mastocarpus papillatus, Lithothamnion sonderi, Odonthalia dentata, and Pleonosporium vancouverianum). The species list of the newly recorded algae contains information on their ecology, fertility, and distribution. The algal taxonomy and nomenclature are updated with new world data.

Four new shallow water species of the genus Pacifigorgia were found in recent surveys along the Pacific coast of Panama. One of the species was only found in dense patches at two shallow seamount-like localities inside the Coiba National Park, Gulf of Chiriqu . Two other species were patchily distributed at several localities in the Gulf of Chiriqu . A fourth species was widely distributed around the gulfs of Chiriqu and Panama encompassing a broad range of habitats and depths. The new species are described and illustrated in detail with scanning electron micrographs (SEM) of the sclerites, and colour photographs of the colony forms. The suspected occurrence of a particular Pacifigorgia species for this region is confirmed and two other new records are added to the species list. With the new four species, a total of 15 are established for Panama, making 31 species for the eastern Pacific to date.

Complete Study

We present results of revision based on our personal data and reports published from 1889 to 2020 on the red algal species composition from the Commander Islands. The general list includes 150 species. Six species are reported for the first time, including Phymatolithon lamii, Neoabbottiella valentinae, Callophyllis beringensis, Kallymeniopsis verrucosa, Velatocarpus kurilensis, and Mazzaella hemisphaerica. These species are illustrated by photographs of samples collected by us from Bering Island in September 2020. Another 15 red algal species reported from this area by different authors we attributed by us to doubtful and incorrectly identified taxa. The list of valid species is organized similarly to that in our recent paper on flora of the green and brown algae from the Commander Islands [Klochkova et al., 2020]. In the list, we cite papers containing information on species records from this area. For all species, information on their distribution frequency, depth, and some ecological and biological features are provided. It is shown that in contrast to many other regions of the Russian Far East, the Commander Islands are well studied from phycological and floristic aspects. This is due to seasonal and year-round investigations carried out in this region in different time periods, a thorough diving survey on the coastal area and more complete study on microepiphyte species composition, including microscopic red algae.

Marine Fishing

Analysis of over 27,000 fish bones from strata at Daisy Cave dated between about 11,500 and 8500 cal B.P. suggests that early Channel Islanders fished relatively intensively in a variety of habitats using a number of distinct technologies, including boats and the earliest evidence for hook-and-line fishing on the Pacific Coast of the Americas. The abundance of fish remains and fishing-related artifacts supports dietary reconstructions that suggest fish provided more than 50 percent of the edible meat represented in faunal samples from the early Holocene site strata. The abundance and economic importance of fish at Daisy Cave, unprecedented among early sites along the Pacific Coast of North America, suggest that early maritime capabilities on the Channel Islands were both more advanced and more variable than previously believed. When combined with a survey of fish remains from several other early Pacific Coast sites, these data suggest that early New World peoples effectively used watercraft, captured a diverse array of fish, and exploited a variety of marine habitats and resources.

A New Species

New World species of the genus Onthophagus Latreille (Coleoptera: Scarabaeidae: Scarabaeinae) have been classified in different ways, all of them without a phylogenetic framework. For instance, Boucomont (1932) separated them in 13 groups of species, but Zunino & Halffter (1988; 1997) only recognize five species groups. Howden & Gill (1993) add the O. dicranius Bates and O. mirabilis Bates species groups, and Kohlmann & Solís (2001) added the O. gazellinus Bates species group. Also, over the years, groups, complexes, and sets of species have been defined using different criteria not even comparable each other. Two of these groupings are the O. dicranius and O. mirabilis species groups, which were firstly separated from the O. clypeatus Blanchard species group (sensu Zunino & Halffter 1981, 1997) by Howden & Gill (1993). After, Kohlmann & Solís (2001) later merged both groups under the O. dicranius species group. Finally, Génier (2017) gives a conceptual framework for species groups and complexes, thus assigning the status of species complex to the two previous species groups, and integrating them in the O. dicranius species group. Herein, we describe a new species of the O. dicranius species complex, update the species list of this complex, and present a revised key to separate these species.

The timing of human entrance into North America has been a topic of debate that dates back to the late 19th century. Central to the modern discussion is not whether late Pleistocene-age populations were present on the continent, but the timing of their arrival. Key to the debate is the age of tools—bone rods, large prismatic stone blades, and bifacially chipped and fluted stone weapon tips—often found associated with the remains of late Pleistocene fauna. For decades, it was assumed that this techno-complex—termed “Clovis”—was left by the first humans in North America, who, by 11,000–12,000 years ago, made their way eastward across the Bering Land Bridge, or Beringia, and then turned south through a corridor that ran between the Cordilleran and Laurentide ice sheets, which blanketed the northern half of the continent. That scenario has been challenged by more-recent archaeological and archaeogenetic data that suggest populations entered North America as much as 15,300–14,300 years ago and moved south along the Pacific Coast and/or through the ice-free corridor, which apparently was open several thousand years earlier than initially thought. Evidence indicates that Clovis might date as early as 13,400 years ago, which means that it was not the first technology in North America. Given the lack of fluted projectile points in the Old World, it appears certain that the Clovis techno-complex, or at least major components of it, emerged in the New World.

Abstract In June 1975, we made the first dry (winter) season observations of puna birds in the Province of Azángaro, Department of Puno, southern Peru, adding nine species to the avifaunal list for the area. We observed no trochilids although they are known to be numerous during the wet (summer) season. Nesting of the Golden-spotted Ground-Dove (Metriopelia aymara) is described for the first time from Peru, and we report the breeding on the puna of two puna species that have been recorded on the coast in the dry season. We discuss altitudinal migration to the Pacific coast during the dry season, and include a species list for this puna region.

The Times

Variability of three SNP loci allocated in the mitochondrial DNA ( One_CO1, One_Cytb_17, One_Cytb_26 ) is analyzed for sockeye salmon from its different habitats from Chukotka to Kuril Islands. Two basic haplotypes (GCC and GTT) are revealed in 20 samples of sockeye ( n = 33-100) from 15 lake-river systems. Their ratio is mostly equal, but GTT haplotype prevails in the populations from Kuril Islands (except Shumshu Island) and is absent in the sample from Commander Islands. This geographical pattern is presumably caused by historical-demographic events related to the species range formation in the middle-late Pleistocene: fragmentation of the areal and subsequent secondary contact between early diverged populations. Two scenarios are discussed, both with multiple expansions of the species to Asia during periods of oceanic transgression after Pleistocene glaciation. According to one of the scenarios, the GTT haplotype has more ancient origin somewhere on the mainland, whereas the GCC appeared much later in the central Kamchatka refugia. The second scenario presumes the origin of both haplotypes on Beringia Bridge where they diverged in the times of middle-Pleistocene (Wurm) glaciation.
