Murree (Pakistan) çevresindeki oldukça bozulmuş iğne yapraklı ormanların vejetasyonu

This phytosociological investigation is conducted in various disturbed forests around Murree hills. The main purpose of study is to explore community types, associated ground flora and their relation to soil characteristics. Eight community types and two monospecific tree stands have been recognized as follows: Pinus wallichiana (pure), Pinus roxburghii (pure), Pinus wallichiana-Quercus baloot, Pinus wallichiana-Cedrus deodara, Pinus wallichiana-Abies pindrow, Pinus wallichiana-Quercus dilatata, Quercus dilatata-Cedrus deodara, Pinus roxburghii-Pinus wallichiana, Pinus roxburghii-Cedrus deodara, Pinus roxburghii-Quercus dilatata. Pinus wallichiana dominates monospecifically in 8 stands while Pinus roxburghii -Pinus wallichiana community types found at 5 locations. Pinus wallichiana formed community type with Cedrus deodara and Abies pindrow at 4 locations separately. Highest stand density achieved in Pinus wallichiana-Cedrus deodara and Pinus roxburghii-Quercus dilatata community i.e. 128 trees/h. Highest basal area (48.06 (m²/ha) recorded from Pinus wallichiana (pure) stands. Pinus wallichiana-Pinus roxburghii communities correlated significantly (p < 0.05) with tree density. Range of DO. pH, Temperature, Conductivity, Salinity, ORP and chemical parameters in each community type has also shown and discussed.Bu fitososyolojik araştırma, Murree tepeleri çevresindeki çeşitli bozulmuş ormanlarda yapılmıştır.

A total evidence phylogeny for the processionary moths of the genus Thaumetopoea (Lepidoptera: Notodontidae: Thaumetopoeinae)

open5noProcessionary moths belong to a group of about 100 species well known for their social behaviour and their urticating systems. The genus Thaumetopoea s.l. includes about 15 species and has been divided into three genera (Helianthocampa, Thaumetopoea s.s., and Traumatocampa) in the last revision, based on key morphological features of the adults and on the host plants of the larvae. We performed a total evidence approach to resolve the phylogeny of the genus Thaumetopoea s.l., analysing all valid taxa included in this group, plus a broad array of close relatives. Thaumetopoea was monophyletic and supported by several apomorphies. Further subclades corroborated by synapomorphies were identified. Our phylogeny suggests that Thaumetopoea must be regarded as a single genus. The mapping of key life history traits on the total evidence tree allowed us to sketch a plausible identikit of the Thaumetopoea ancestor and to track the evolution of the genus. The ancestor originated in the eastern Mediterranean area, and used broadleaved host plants. Subsequently, a switch to conifers occurred, just once, in a large subclade. The ancestor pupated in the soil, like several current species, but in a few taxa this trait was lost, together with the related morphological adaptations.embargoed_20190305Basso, A; Negrisolo, E; Zilli, A; Battisti, A; Cerretti, PBasso, Andrea; Negrisolo, ENRICO MASSIMILIANO; Zilli, A; Battisti, Andrea; Cerretti, P

Palaeoclimate changes in the Afyon province, Sw-Turkey, during the Middle-Late Pleistocene: Signals from calcareous tufa pollen and stable isotope records

The calcareous tufas of Sarikavak located in the northern part of NE-SW trending Acigöl Graben in SW-Turkey are investigated in detail. For this aim, various analyses (stable isotopes, U/Th dating, palynology) have been carried out on samples obtained from both outcrops and drilling logs in and surrounding Sarikavak Village. U/Th dating shows that these carbonates precipitated from 400 ka up to 80 ka. Preliminary pollen data, document climatic variability between MIS 11 and MIS 8 in the studied area. © 2010 AIQUA - Associazione Italiana per lo Studio del Quaternario e EMMEVI - Servizio Congressi SPA

The Holocene Cedrus pollen record from Sierra Nevada (S Spain), a proxy for climate change in N Africa

Comprehending the effects of climate variability and disturbance on forested ecosystems is paramount to successfully managing forest environments under future climate scenarios (e.g., global warming, aridi-fication increase). Changes in fossil pollen abundance in sedimentary archives record past vegetation dynamics at regional scales, mainly related to climate changes and, in the last few millennia, to human impact. Pollen records can thus provide long databases with information on how the environment reacted to climate change before the historical record. In this study, we synthesized fossil pollen data from seven sites from the Sierra Nevada in southern Spain to investigate the response of forests in the western Mediterranean area to millennial-scale climate changes and to human impact during the Holocene. In particular, here we focused on Cedrus pollen abundances, which most-likely originated from Northern Africa and were carried to Sierra Nevada by wind. Cedrus pollen has received little attention in the Iberian Peninsula palynological records, for it occurs in low concentrations and has an African source, and thus this article explores the potential to reconstruct its past history and climate. Although Cedrus abundances are generally lower than 1% in the studied pollen samples, a comparison with North African (Moroccan) Cedrus pollen records shows similar trends at long- and short-term time-scales. Therefore, this record could be used as a proxy for changes in this forest species in North Africa. As observed in the Sierra Nevada synthetic record, the increasing trend of Cedrus pollen during the Middle and Late Holocene closely correlates with decreasing summer insolation. This would have produced overall cooler annual temperatures in Northern Africa (Middle Atlas and Rif Mountains) as well as lower summer evaporation, benefiting the growth of this cool-adapted montane tree species while increasing available moisture during the summer, which is critical for this water-demanding species. Millennial-scale variability also characterizes the Sierra Nevada Cedrus synthetic pollen record. Cedrus abundance oscillations co-vary with well-known millennial-scale climatic variability that controlled cedar abundance and altitudinal distribution in montane areas of N Africa.

Measuring sexual interest using a pictorial modified Stroop task, a pictorial Implicit Association Test, and a Choice Reaction Time task

Tasks that can successfully measure sexual interest have utility in forensic settings. Prior to use with problematic sexual interest however, work is needed in validating such tasks. This study focused on the measurement of non-deviant sexual interest. Eleven gay and fourteen straight participants each completed a pictorial Implicit Association Test (IAT), a pictorial modified Stroop task (P-MST) and a Choice Reaction Time (CRT) task. Each task was designed to tap into the sexual interest of participants. Stimuli were of males and females in bathing suits along with control images and sexual and non-sexual words. The IAT was most successful in differentiating between gay and straight participants. The P-MST also performed well, though the task’s position in the battery of tasks seemed to affect the results. The CRT tasks did not successfully show group differences. Theoretical and methodological implications of the effectiveness of the three tasks in tapping into sexual interest are discussed

Cedrus libani

Cedar of Lebanon had an extensive ancient range through Lebanon, Syria, and Southern Turkey. It now is greatly reduced and fragmented through economic exploitation for 5000 years, agricultural clearing, and war. Populations are found in the Taurus Mountains and Black Sea region of Turkey, the eastern side of Jabal an-Nusayriya in Syria, and the western mountain range in Lebanon (Khuri 2000)

Steppes, savannahs, forests and phytodiversity reservoirs during the Pleistocene in the Iberian Peninsula

A palaeobotanical analysis of the Pleistocene floras and vegetation in the Iberian Peninsula shows the existence of patched landscapes with Pinus woodlands, deciduous and mixed forests, parklands (savannah-like), shrublands, steppes and grasslands. Extinctions of Arctotertiary woody taxa are recorded during the Early and Middle Pleistocene, but glacial refugia facilitated the survival of a number of temperate, Mediterranean and Ibero-North African woody angiosperms. The responses of Iberian vegetation to climatic changes during the Pleistocene have been spatially and temporarily complex, including rapid changes of vegetation in parallel to orbital and suborbital variability, and situations of multi-centennial resilience or accommodation to climatic changes. Regional characteristics emerged as soon as for the Middle Pleistocene, if not earlier: Ericaceae in the Atlantic coast indicating wetter climate, thermo-mediterranean elements in the south as currently, and broad-leaf trees in the northeastern. Overall, steppe landscapes and open Pinus woodlands prevailed over many continental regions during the cold spells of the Late Pleistocene. The maintenance of a high phytodiversity during the glacials was linked to several refuge zones in the coastal shelves of the Mediterranean and intramountainous valleys. Northern Iberia, especially on coastal areas, was also patched with populations of tree species, and this is not only documented by palaeobotanical data (pollen, charcoal) but also postulated by phylogeographical models
