The present research deal with ecological and geographical distribution of species and genera of Primulaceae in Iraq. The results were revealed that species distributed in the north , north-east and west of Iraq. Anagallis arvensis L. is the most prevalent species tolerant to different environmental conditions, while the species of Primula L. characterized as less widespread and limited in one District. In addition, the districts Rawanduz (MRO) and Sulaymaniyah (MSU) have ranked first in distribution of the species on geographical districts with (75%), while the districts southern desert (DSD) and Basra (LBA) in last place with (16.7%). Maps for geographical distribution for all species were illustrated.

The geographical distribution of Morpho helenor (Cramer) in Bolivia is mapped from the study of specimens preserved in Bolivian and foreign collections, and from recent field studies in various ecoregions. One subspecies, M. h. theodorus Fruhstorfer, inhabits Amazonian moist forests in the western and northern parts of the country. Another subspecies, M. h. coelestis Butler, is common in moist cloud forests (Bolivian Yungas), but also occurs to the North and North-East. We describe a new subspecies, M. h. prometa ssp. nov., from Southern Andean Yungas. Transition zones between theodorus and coelestis are highlighted, where specimens exhibiting intermediate phenotypes were collected. The pattern of geographic transition from M. h. coelestis to M. h. prometa needs to be documented. M. h. prometa inhabits sub-humid, semideciduous forests, whereas M. h. theodorus and M. h. coelestis live in rainforests. M. h. coelestis populations are found from less than 100 m to more than 1600 m a.s.l.; M. h. theodorus has been collected at more than 1000 m a.s.l.; and M. h. prometa between 500 m and 1400 m a.s.l.. Therefore, Bolivian M. helenor populations are distributed throughout a wide range of ecological contexts: we discuss the habitat plasticity of the species in light of available knowledge of its geographical distribution and habitats in the Neotropical Region.

This is a cave in the Mountain Limestone, with a wide entrance looking to the north-east at about 70 feet above the level of the valley beneath, up which the tide has recently flowed. The cave extends tortuously for 30 or 40 yards into the axis of a ridge which is a spur of the “Ridgeway,” extending from Pembroke to Tenby, composed of the Old Red, the strike of which is east and west.Within, the cave is distinguished by chambers, alternating with narrow passages. The floor is generally not more than three feet deep, at which depth the limestone is met with as at the roof and sides. The entrance being conspicuous, it is often visited from curiosity, but has never before been carefully explored for the definite purpose of discovering works of ancient art. This search was prompted by the recent discoveries in France and at Hoxne, strongly seconded by the fact that above, on the Ridgeway, some six or seven barrows exist, which yielded to the reporter and others a few years since, not only cinerary urns, but also well-shaped flint arrow-heads.So much by way of introduction.The Section will be glad to learn that the search in this cave for flint weapons has been successful, and that the number found is seventy-three, including the identical lumps of flint which remained after the chips had been struck off, when from their reduced size they were no longer capable of yielding flakes sufficiently large to answer the destined purpose, whatever that might be.

About 10 metres south-west of the sixth-century temple of Hera Akraia at Perachora, and nearly due west of the little harbour lies the small courtyard previously known as the ‘Agora’. Since its purpose is not known, it will here be non-committally referred to as the West Court. It was first excavated in 1932, and more fully, under the supervision of J. K. Brock, in 1933, but it was not entirely cleared until 1939, and it was at that time that the Roman house which stood in the middle of the court was demolished. The West Court is discussed briefly (under the name of ‘Agora’) in Perachora 1 and in the preliminary reports of the Perachora excavations. Short supplementary excavations were carried out in 1964 and 1966 to examine certain points of the structure.In shape the West Court is an irregular pentagon, about 24 metres from north to south and the same from east to west (Fig. 1; Plate 91 a, b). It is enclosed on the west, north, and on part, at least, of the east side by a wall of orthostates on an ashlar foundation. For a short distance on either side of the south corner, the court is bounded by a vertically dressed rock face which is extended to the north-east and west by walls of polygonal masonry. At the south-west corner the west orthostate wall butts against the polygonal wall, which continues for about 0·80 m. beyond it and then returns north for about 8 metres behind it.

Dear Sir,The earthquakes which have lately taken place at Comrie and its neighbourhood, are certainly very deserving of attention. I shall therefore cheerfully comply with your request, and give you as particular a description as I can of such of them as have been most remarkable. To give a particular account of all the noises or concussions which, during the last half-year, have been heard or felt at Comrie, and within a short distance to the north, east and west of that village, is beyond my power, and would indeed be of little use.

The author states that, “About half-past 7 p. m. the sky assumed the appearance which it usually does immediately preceding the action of what are called the Northern Lights. In the northern half it was quite clear for about forty-five degrees from the meridian, of a pale blue, and covered with a faint light, such as generally ushers in the moon at her rising. Towards the east and west this light gradually diminished, and south of those cardinal points the dimness as gradually thickened. “Soon after eight the coruscations began by the usual lambent strokes of a shining filmy matter, like the sudden shooting forth and instantaneous retroceding of a serpent’s tongue. They commenced in the north-east, and shot upwards in an angle of about 70 degrees of inclination towards the south, and to about 60 degrees in length, more or less, leaving the sky clear to the north, and in a manner gradually chasing the clouds, upon whose receding bounds they glanced further to the south.

Carboniferous Limestone

The Hill of Beath, which lies 3 miles to the north-east of Dunfermline, Fife, is an isolated hill with steep, but rounded, contours, and rises fully 250 feet above the surrounding plateau. Whilst the hill itself consists of dark grey tuff, the rocks forming the plateau belong to the Coal-measures of the Carboniferous Limestone series. The latter are thrown into gentle anticlines and synclines, the dip on the limbs of the folds usually lying between 10 and 15 degrees. The outcrop of the tuff has the form of an ellipse, the long axis of which trends east and west and measures nearly 1,000 yards, whilst the breadth of the ellipse is rather more than 500 yards. The distribution of the outcrops of the Carboniferous rocks around the hill and the evidence from the coal workings show that the tuff is not interbedded with the sediments, but that it breaks through them somewhat like an intrusive rock. Sir Archibald Geikie recognized that the Hill of Beath was a volcanic neck, and this view has been confirmed by recent mining operations in a conclusive manner.

The cognitive performance of groups of subjects was tested after flights lasting between 7.5–9.5 hours to the north, east and west of Sydney ( ns = 10, 12, and 12) and compared with the performance of a ground-based control group ( n = 12). Analysis showed an impairment in performance of the flight groups following the flights. The analysis suggests that part of the performance change following transzonal flights may result from stress induced during the flight rather than adjustment to new time zones.

Oat Breeding

SummaryThree composite populations of oats were grown at contrasting sites in the north, east and west of Scotland for four successive generations from F3 to F6. Analyses of variance and canonical analysis both showed that the genetic constitution of the composites was responsible for a greater proportion of the variation than locations (sites). This suggests that either natural selection was not operating to any great extent or the effect of natural selection was very similar at the three sites. These findings were supported when selections were taken from one of the populations and subjected to canonical analysis. The implications for oat breeding in Scotland are discussed.

There have been presented the study results of 11 collection hulled oats samples in comparison with the standard variety ‘Krechet’ conducted at the Falenskaya selection station of the FARC the North-East (the Kirov region) in 2018–2020. The purpose of the current study was to identify sources stable on the trait ‘1000-grain weight’ for the breeding of hulled oats by estimating the adaptability parameters. The soil of the experimental plot was sod-podzolic, medium loamy, the meteorological conditions were contrasting in temperature and precipitation. In the favorable year of 2019, the 1000-grain weight was the highest (34.6–45.9 g), the index of environmental conditions was positive (Ij = 1.6). In the unfavorable year of 2020, the 1000-grain weight was 31.3–41.8 g and the index of environmental conditions was negative (Ij = -1.5). There have been identified the adaptable sources (IEP = 1.08–1.00) ‘15330 KSI 590/05’ (Russia), ‘15388 Saltaret’ (Moldova), ‘15423 Prelekst’, ‘15426 Werva’ (Germany); the stable sources according to the relative stability of the trait (St2 = 0.99–0.91) ‘15280 55 h 2106’, ‘15331 CSI 2167/03’ (Russia), ‘15297 Geszti’ (Hungary), ‘15388 Saltaret’ (Moldova), ‘15428 Bohum’ (Poland), ‘15420 Leniak’ (Germany); the sources with a high level of intensity (I = 24.5 and 19.30%) – ‘15329 CSI 639/05’, ‘15330 CSI 590/05’ and homeostaticity (Hom = 25.28–11.96) ‘15280 55 h 2106’ (Russia), ‘15297 Geszti’ (Hungary), ‘15388 Saltaret’ (Moldova); the sources responsive to favorable growing conditions (Kp = 1.11–1.28) ‘15329 KSI 639/05’, ‘15330 KSI 590/05’, ‘15331 KSI 2167/03’ (Russia), ‘15414 Enostar’ (Germany); the most adaptive sources in terms of the sum of ranks ‘15330 CSI 590/05’ and ‘15329 CSI 639/05’ (Russia), ‘15388 Saltaret’ (Moldova), ‘15426 Werva, ‘15414 Enostar’ (Germany). There have been identified significant direct correlations between indicators of stability and homeostaticity (r = 0.96), intensity and coefficient of responsiveness (r = 0.73).
