| 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... |

| This article investigates the production efficiency of rice farming in Sri Lanka using cross section survey data of 90 farms. Past studies on rice farming have mostly focused on technical efficiency (TE). Here, we examine technical efficiency, allocative efficiency (AE) and cost efficiency (CE) using the data envelopment analysis (DEA) approach. On average, the farms were 87% technically efficient; irrigated farms were more efficient (88%) than rain-fed farms (82%). Average cost, allocative and scale efficiencies were 73%, 84% and 87%. Bias corrected TE estimate suggests an expected output expansion of 25% with a given input combination in order to become fully efficient as opposed to 16% based on the original estimates. In addition, a second stage Tobit... |

| 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... |

| Participatory approaches in natural resource management are increasingly being criticized for their tendency to neglect power relations and conflicts of interests. Negotiation approaches have been proposed as a strategy to overcome such shortcomings. Using the case of negotiations on crop-livestock conflicts in Sri Lanka as an empirical example, this paper proposes to apply the concept of political capital in combination with game theoretical modeling for an analysis of negotiation processes in natural resource management. The model serves to analyze both the incentive structure of the resource users, who are motivated by economic incentives, and the incentive structure of political decision-makers, who are motivated by political interests. The crucial... |

| 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.... |

| After discussing definitions of ecotourism, outlines possible economic and conservational benefits from developing ecotourism or wildlife-based tourism. Identifies possible economic benefits for local communities but also outlines possible economic costs to such communities. Observations are made on the potential of developing ecotourism in the Giant’s Tank/Mannar area. A sufficient market does not always exist for wildlife-based tourism to make it economically viable. Therefore, market analysis should be undertaken before promoting the development of wildlife-based tourism in a locality. A checklist is provided to give some guidance in market appraisal. It is observed that even non-consumptive wildlife-based tourism can have adverse environmental... |

| 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... |

| 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... |

| After two decades of liberalized economic policies together with early accession to WTO, Sri Lanka could not achieve the exp ected fast economic growth. Agriculture growth in particular fell sharply. WTO Doha round expects a deeper liberalization. Instead, we will benefit more from being a friend of the "Development Box" and securing flexibility in tariff revisions. In asserting this, the paper analyzes impacts of liberalized policies on agriculture, stress the need for flexible trade policies and formulate a design for self designating Special Products (SP) and Special Safeguard Mechanisms (SSM). The past economic growth favoured mostly urbanised population. Sluggish rural agricultural growth, hurt with increased food imports, was the main cause of this... |
