Phenotypic Plasticity and Local Adaptation of Leaf Cuticular Waxes Favor Perennial Alpine Herbs under Climate Change

Six perennial herbs (Plantago asiatica, Polygonum viviparum, Anaphalis lactea, Kobresia humilis, Leontopodium nanum and Potentilla chinensis) widely distributed in alpine meadows were reciprocally transplanted at two sites in eastern edge of Qinghai-Tibetan Plateau, Hongyuan (3434 m, 2.97 °C, 911 mm) and Qilian (3701 m, 2.52 °C, 472 mm), aiming to evaluate the responses of alpine plants to changing environments. When plants were transplanted from Hongyuan to Qilian, most plant species showed a decrease of total wax coverage in first year and reverse trend was observed for some plant species in second year. However, when plants were transplanted from Qilian to Hongyuan, the response of total wax coverage differed greatly between plant species. When compared with those in first year, plasticity index of average chain length of alkane decreased whereas carbon preference index of alkane increased at both Hongyuan and Qilian in second year. The total wax coverage differed between local and transplanted plants, suggesting both environmental and genetic factors controlled the wax depositions. Structural equation modeling indicated that co-variations existed between leaf cuticular waxes and leaf functional traits. These results suggest that alpine herbs adjust both wax depositions and chain length distributions to adapt to changing environment, showing climate adaptations.

First report of the Southern Gulf Coast Toad (Incilius valliceps Wiegmann), Common House Gecko (Hemidactylus frenatus Duméril and Bibron), Schmidt’s Black-Striped Snake (Coniophanes schmidti Bailey), and Cozumel Whiptail (Aspidoscelis cozumela Gadow), on Turneffe Atoll, Belize

Each year from 2012 to 2019, during a 12-day period in November or December, we photographed common herpetofauna on Calabash Caye, a small mangrove-dominated island on the eastern edge of Turneffe Atoll, Belize. Turneffe Atoll is home to the newest, largest, and most biodiverse marine protected area in Belize. Calabash Caye exemplifies the islands on Turneffe’s eastern edge whose elevated beach ridges enable the development of coastal strand plain and littoral forest habitats, which are among the most threatened habitats in the world. As no herpetofaunal survey has been published for Turneffe in over twenty years, and as the herpetofauna is a conspicuous indicator of the health of terrestrial ecological communities on islands, we leveraged our annual field excursions to Calabash Caye to compile a photographic record of the island’s reptiles and amphibians. In multiple years, we documented the presence of five lizards (Anolis sagrei mayensis, Aspidoscelis cozumela, Ctenosaura similis, Phyllodactylus tuberculosus, and the invasive species Hemidactylus frenatus), three snakes (Boa imperator, Leptophis mexicanus hoeversi, and Coniophanes schmidti), and one amphibian (Incilius valliceps). This represents the first report of A. cozumela, H. frenatus, C. schmidti, and I. valliceps on Calabash Caye or on any island in Turneffe Atoll; H. frenatus, C. schmidti, and I. valliceps have never been reported on any of the Belizean cayes. We did not observe four species that have previously been reported on Calabash Caye: Brown Basilisk (Basiliscus vittatus), Mesoamerican Cane Toad (Rhinella horribilis), Mayan Skink (Marisora lineola; formerly Mabuya unimarginata), or a blindsnake, provisionally identified as Indotyphlops braminus. We also include photos of Anolis allisoni, Ctenosaura similis, and Anolis sagrei mayensis obtained during four single-day excursions to Half Moon Caye on Lighthouse Atoll; this represents three of four species reported from that location during the 1990s.

Kaoline Mapping Using ASTER Satellite Imagery: The Case Study of Kefalos Peninsula, Kos Island

The present work aims to map kaolin occurrences on the Kefalos peninsula, SW Kos Island, Greece, through the elaboration of ASTER satellite imagery. The island of Kos is located on the eastern edge of the South Aegean Active Volcanic Arc (SAAVA) and is characterised by its complex geologic structure. During Plio-Pleistocene, the voluminous eruption of the Kos Plateau Tuff was recorded on Kefalos; the largest quaternary eruption in the Mediterranean. Kaolin is the product of hydrothermal alteration of the Pliocene volcanic rocks with rhyolitic composition. Our study emphasises the usefulness of satellite imagery combined with the Mixture Tuned Matched Filtering (MTMF) technique to detect occurrences of industrial minerals, kaolin-group minerals in this case, either in terms of raw mineral exploitation or by mapping hydrothermal alteration.

Chapter Six: The Arcuate Polygonal-Block Wall at Eleon

The dominant archaeological feature visible at Eleon is a Late Archaic polygonal- block wall that extends 85 m southward from the excavated site along the eastern edge of the plateau, constructed from finely fitted panels of local grey limestone averaging 2 tons in weight. The wall is arcuate for most of its length and finished on each end with an angular bastion. Every part has lost at least one course, and the wall is completely leveled or buried for most of its length, but was originally at least four courses high, standing 4.5 m above its base. The north end of the wall underwent a low-quality ancient reconstruction. The techniques used to shape and shift the stone are considered, and the wall is compared with other stonework at the site. Further study will allow more thorough analysis of the wall’s archaeological context and its relationship with other Archaic and Classical constructions.

Tracking the Source of Solar Type II Bursts through Comparisons of Simulations and Radio Data

The most intense solar energetic particle events are produced by coronal mass ejections (CMEs) accompanied by intense type II radio bursts below 15 MHz. Understanding where these type II bursts are generated relative to an erupting CME would reveal important details of particle acceleration near the Sun, but the emission cannot be imaged on Earth due to distortion from its ionosphere. Here, a technique is introduced to identify the likely source location of the emission by comparing the dynamic spectrum observed from a single spacecraft against synthetic spectra made from hypothesized emitting regions within a magnetohydrodynamic (MHD) numerical simulation of the recreated CME. The radio-loud 2005 May 13 CME was chosen as a test case, with Wind/WAVES radio data being used to frame the inverse problem of finding the most likely progression of burst locations. An MHD recreation is used to create synthetic spectra for various hypothesized burst locations. A framework is developed to score these synthetic spectra by their similarity to the type II frequency profile derived from the Wind/WAVES data. Simulated areas with 4× enhanced entropy and elevated de Hoffmann–Teller velocities are found to produce synthetic spectra similar to spacecraft observations. A geometrical analysis suggests the eastern edge of the entropy-derived shock around (−30°, 0°) was emitting in the first hour of the event before falling off, and the western/southwestern edge of the shock centered around (6°, −12°) was a dominant area of radio emission for the 2 hr of simulation data out to 20 solar radii.

Bronze Age Funerary and Later Prehistoric Activity at Badminston Farm, Fawley, Hampshire

Archaeological excavations were undertaken by Southern Archaeological Services Ltd. between 1999 and 2010 at Badminston Farm, Fawley, on the eastern edge of the New Forest, adjacent to Southampton Water. The excavations identified evidence of near- continuous human activity from the early prehistoric period to the present day. Mesolithic activity was followed by Early Bronze Age pits, containing 'placed' flint assemblages. Evidence of Bronze Age funerary activity included deflated barrows/ring ditches, and associated cremations. Late Bronze Age ceramics were absent but a hoard of 68 Armorican-type socketed axes may have been a votive offering marking the 'ancestral' barrow which would have been visible here. Other Bronze Age evidence included two burnt mounds and an ill-defined structure possibly associated with weaving. Iron Age activity was represented by a number of pits containing domestic pottery, while Late Iron Age and Romano-British ditches may have formed part of an enclosure. A significant assemblage of non-local worked stone attests to long distance exchange, and the possibility of a nearby farmstead. Medieval activity was represented by pits, ditches and stakeholes, with some evidence of an enclosure or structure associated with grain drying. Later land divisions and a WWII radio communication station dominated more recent use of the site.

Changes in the Townscape of Lampertszásza (Berehove/Beregszász) in the 13th–15th Centuries

Across the River Tisza, there lies a town, Berehove (hereinafter also referred to as Beregszász [Hu]), situated on the north-eastern edge of the Great Hungarian Plain with the wind swaying ears of wheat, on the flatlands surrounded by rustling oak forests, gold-sweating trachyte mountains, and rivers subsiding upon reaching the plain. It is a veritable fairy garden, a small piece of the realm that out foremother, Emese, dreamt of back in the day. Places, just as people, have their own destinies: they emerge, evolve, thrive, and then, if they are destined so, disappear from the stage of history. The very first mention of Berehove dates back to early 1063, recorded under the name Lamperti, as the estate of Prince Lampert, son of Béla I of Hungary. Prince Lampert founded the later town. At the time, a small settlement must have been situated here with the prince’s countryseat inhabited by the garrison and the household servants. Residents of the house were mostly the gamekeepers and huntsmen of Bereg Forest County. To fully uncover the past is not possible – at the very most, some attempts can be made at its reconstruction by drawing on contemporary sources and relying on archaeological research. The mediaeval layout of the settlement is known from the available sources and serves as a basis for the present study in its efforts to reconstruct the settlement image of the historical town centre and to find out why Lampertszásza did not embark on the path of the ‘classic, city wall/fortification’ type of settlement development. The parish church is the only building of the mediaeval townscape that has survived partially, which, however, provides us with indications about the contemporary buildings of the one-time reginal town and the related ‘block of church buildings’.

The environmental context of Early Neolithic cultural transformation in the Targowisko settlement region

The aim of this article is to provide information on environmental changes in the Targowisko region in the Early Neolithic as a natural response to settlement and economic activity of the human population in that area. The discussion is based on lithological, geochemical, and palynological analyses, as well as the analysis of Cladocera within strata inside the TRG (Targowisko) core, located in a small wetland in the immediate vicinity of the eastern edge of the Neolithic settlement in the Targowisko region. Settlement analysis points to the absence of stable microregions and to the mobility of human groups. This is confirmed by the sequence of settlement episodes and economic activity, reflected in the stratigraphy of the core sediments, where episodes of significant human interference are followed by phases of almost complete regeneration of the environment. No differences have been noticed between the Linienbandkeramik and Malice culture communities as regards their impact on the environment.
