| ABSTRACT Six wide-ranging mangrove species, Rhizophora apiculata, R. mucronata, Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, and B. sexangula, were selected to study the growth and survival of seedlings under three contrasting salinity treatments over a 30-week period: low (3-5psu), moderate (15-17psu) and high (33-36psu). Seedlings grown under high salinity exhibited significantly lower performance (p<0.05) in survival rates, cumulative shoot height, mean growth rates, mean total leaf area, and mean dry weight, compared to those under low and moderate salinity regimes. The low salinity treatment provided the best conditions for initial establishment and growth of the seedlings of all species until 15-20 weeks of age. However, the same... |

| Evidence shows a clear racial variation in the position of the mental foramen. Therefore, detailed knowledge of the morphometry of the mental foramen in different populations is essential in clinical dentistry when administering regional anesthesia, and performing peripheral surgery in the mental region of the mandible. The goal of this study was to elucidate the morphological features and precise anatomical position of the mental foramen with reference to surrounding anatomical landmarks in an adult Sri Lankan population. A total of fifty one adult dry mandibles were assessed to determine the number, shape, orientation, vertical and transverse diameters of the mental foramen and the distance between the mental foramen and symphysis menti. The position of... |

| Evidence supports a clear racial variation in the position of the infraorbital foramen. Therefore detailed knowledge of the population specific data on biometric features of the infraorbital foramen will facilitate therapeutic, diagnostic and surgical manipulations in the maxillo-facial region. The goal of this study was to elucidate the morphological features and precise anatomical position of the infraorbital foramen with reference to surrounding anatomical landmarks in an adult Sri Lankan population. A total of one hundred and eight adult dry skulls were assessed to determine the number, shape, orientation, vertical and transverse diameters of the infraorbital foramen, transverse distance from the infraorbital foramen to the maxillary midline and the... |

| Dimensional relationship between body segments and stature has been the focus of scientists for many years. All such studies were based on the fact that body segments exhibit consistent ratios relative to the stature and these ratios are linked to age, gender and race. Racial characters are best defined in the skull. Therefore, prediction of stature from cranial remains is vital in establishing the identity of an unknown individual. Despite its significance, little is known concerning the cranial dimensions in Sri Lankans. Hence, this study was designed to investigate the relationship and to propose a gender and age specific linear regression model between the cranial dimensions and height of an individual. A total of 400 subjects with an age span of 20-23... |

| Cephalic index is an important parameter in evaluating racial and gender differences. A large body of evidence shows a clear racial variation in cephalic index. Therefore detailed knowledge of the population specific data on biometric features of the cranium is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its' significance, little is known concerning the cranial morphometry in Sri Lankans. Hence, the present study was undertaken to establish the cranial indices and head shapes in an adult Sri Lankan population. A total of 400 subjects with an age span of 20-23 years were... |

| Evidence supports a clear racial variation in the position of the greater palatine foramen. Therefore detailed knowledge of the population specific data on biometric features of the greater palatine foramen will facilitate therapeutic, local anesthetic and surgical manipulations in the maxillo-facial region. The goal of this study was to elucidate the morphological features and precise anatomical position of the greater palatine foramen with reference to surrounding anatomical landmarks in an adult Sri Lankan population. A total of one hundred and thirty six adult dry skulls were assessed to determine the number, shape, direction of opening of the greater palatine foramen and straight distance from it to the palatine midline, posterior margin of the hard... |

| Cranial capacity exerts a close correlation with the volume of the brain. A large body of evidence shows a clear racial variation in cranial dimensions. Therefore detailed knowledge of the population specific data on biometric features of the cranial cavity is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its significance, little is known concerning the cranial capacity in Sri Lankans. Hence, the present study was undertaken to establish the cranial capacity in an adult Sri Lankan population. A total of 210 subjects with an age span of 20-23 years were included in the study.... |

| The taxonomic status of the colubrid snake Dendrelaphis tristis (Daudin, 1803) was investigated on the basis of morphological data taken from 64 museum specimens. Univariate and multivariate analyses of these data reveal that Dendrelaphis tristis is composed of two species. One of these species agrees with the description of Dipsas schokari Kuhl, 1820 which is revalidated in the combination Dendrelaphis schokari (Kuhl, 1820). The syntypes of D. schokari have been lost and a type for D. tristis has never been deposited in a collection. Neotypes are designated and described for both species in order to stabilize the names. D. schokari differs from D. tristis in having a lower number of ventrals and subcaudals, a larger eye, a shorter vertebral stripe and the... |

| Georg Eberhard Rumphius (1627–1702), author of the monumental work Herbarium Amboinense (1741–1755) is seen as the undisputed patriarch of Malesian Natural Sciences. Until recently, it was thought that if Rumphius had collected any specimens, they all had been lost. The recent digitisation and revision of two book herbaria in Leiden collected by Paul Hermann (1646–1695) on Ceylon revealed four specimens with reference to either Rumphius or Ambon in Hermann’s handwriting: Colocasia esculenta, Gomphrena globosa, Helminthostachys zeylanica and Biophytum sensitivum, of which the latter does not occur in Sri Lanka. Here we discuss the description of these species in both published and unpublished historic works and consider the possibility that they may... |

| Throughout the world, infections with the Babesia and Theileria parasites often result in economically significant clinical disease in cattle. We conducted a longitudinal survey of Babesia and Theileria infections in cattle from the Polonnaruwa (n?=?75; dry zone) and Nuwara Eliya (n?=?161; wet zone) districts of Sri Lanka. DNA from blood samples collected in June, September, and December 2014 and March 2015 was screened for Babesia bovis, Babesia bigemina, Theileria annulata and Theileria orientalis using specific polymerase chain reactions (PCRs). Additionally, serum samples collected from the animals were screened using enzyme-linked immunosorbent assays (ELISAs) to detect B. bovis- and B. bigemina-specific antibodies. All of the animals surveyed in... |

| In Sri Lanka coconut poonac, a byproduct produced from the coconut oil production process, is being used for feeding dairy cattle. Though poonac is cheaper than formula feed, it is feared that the bad effects of cattle health due to its high fat content. This study clarified the economic effect of poonac feeding on dairy farming. We conducted interview survey with 40 small-scale farms in Kurunegala District, and analyzed the relationship among poonac feeding, cattle disease rate, raw milk production and dairy farming income by using the multiple regression analysis. The risk of cattle disease increased as poonac feeding. On the other hand, participation in the feeding training was effective in reducing outbreaks of disease in dairy cattle. Moreover, we... |
