Plasmodium vivax is the geographically most widespread human malaria parasite. To analyze patterns of microsatellite diversity and population structure across countries of different transmission intensity, genotyping data from 11 microsatellite markers was either generated or compiled from 841 isolates from four continents collected in 1999–2008. Diversity was highest in South-East Asia (mean allelic richness 10.0–12.8), intermediate in the South Pacific (8.1–9.9) Madagascar and Sudan (7.9–8.4), and lowest in South America and Central Asia (5.5–7.2).

Niche dynamics of Memecylon in Sri Lanka: distribution patterns, climate change effects, and conservation priorities

Prabha Amarasinghe, Narayani Barve, Hashendra Kathriarachchi, Bette Loiselle & Nico Cellinese
Aim: Recent climate projections have shown that the distribution of organisms in island biotas is highly affected by climate change. Here, we present the results of the analysis of niche dynamics of a plant group, Memecylon on Sri Lanka, an island, using species occurrences and climate data. We aim to determine which climate variables explain current distribution, model how climate change impacts the availability of suitable habitat for Memecylon, and determine conservation priority areas for...

Rodewald, Robert L. Thomson, Pranav Trivedi, Steven L. Van Wilgenburg … & Kartik Shanker
Competition theory predicts that communities at small spatial scales should consist of species more dissimilar than expected by chance. We find a strikingly different pattern in a multi-continent dataset (55 presence-absence matrices from 24 locations) on the composition of mixed-species bird flocks, important subunits of local bird communities the world over. Using null models and randomization tests followed by meta-analysis, we find the association strength of species in flocks to be strongly related to similarity...

Data from: Ecological and environmental predictors of escape among birds on a large tropical island

Kasun B. Ekanayake, Jonathan J. Gnanapragasam, Kithsiri Ranawana, Dulan R. Vidanapathirana, U. Tiran Abeyawardhana, Chandima Fernando, Alexandra McQueen, Michael A. Weston & Matthew R.E. Symonds
Ecological and environmental traits can influence avian escape behaviour but most data underpinning our current understanding relates to continental and temperate areas and species. We conducted a phylogenetically controlled comparative analysis of flight-initation distance (FID) against a variety of environmental, behavioural and life-history attributes for Sri Lankan birds (202 species; n = 2540). As with other studies, body mass was positively associated with FID, and longer FIDs occurred in areas where human population density was...

Meal replacement as a weight loss strategy for night shift workers with obesity: a protocol for a randomized controlled trial

Piumika Sooriyaarachchi, Ranil Jayawardena, Toby Pavey & Neil A. King
Abstract Background Shift work is considered a risk factor for a number of chronic health conditions including obesity. Weight reduction in obese patients lowers the risk for cardiovascular disease, diabetes, certain cancers, and mortality. Achieving a negative energy balance by providing low-calorie meal replacements is widely used for weight management. This study aims to evaluate the impact of a low-calorie “meal-replacement” on the weight and metabolic parameters of shift workers with obesity. Methods This trial...

Data from: Mental health status of Sri Lanka Navy personnel three years after end of combat operations: a follow up study

Raveen Hanwella, Nicholas E. L. W. Jayasekera & Varuni A. De Silva
The main aim of this study was to assess the mental health status of the Navy Special Forces and regular forces three and a half years after the end of combat operations in mid 2009, and compare it with the findings in 2009. This cross sectional study was carried out in the Sri Lanka Navy (SLN), three and a half years after the end of combat operations. Representative samples of SLN Special Forces and regular...

Data from: Low levels of hybridization across two contact zones among three species of woodpeckers (Sphyrapicus sapsuckers)

Sampath S. Seneviratne, Peter Davidson, Kathy Martin & Darren E. Irwin
Three species of closely related woodpeckers (sapsuckers; Sphyrapicus) hybridize where they come into contact, presenting a rare ‘λ‐shape’ meeting of hybrid zones. Two of the three arms of this hybrid zone are located on either side of the Interior Plateau of British Columbia, Canada bordering the foothills of the Coast Mountains and the Rocky Mountains. The third arm is located in the eastern foothills of the Rocky Mountains. The zones of hybridization present high variability...

Population genomics of an emergent tri-species hybrid zone

Libby Natola, Sampath Seneviratne & Darren Irwin
Isolating barriers that drive speciation are commonly studied in the context of two-species hybrid zones. There is however evidence that more complex introgressive relationships are common in nature. Here, we use field observations and genomic analysis, including the sequencing and assembly of a novel reference genome, to study an emergent hybrid zone involving two colliding hybrid zones of three woodpecker species: red-breasted, red-naped, and yellow-bellied sapsuckers (Sphyrapicus ruber, S. nuchalis, and S. varius). Surveys of...

Effects of meditation on physiological and metabolic parameters in patients with type 2 diabetes mellitus “MindDM”: study protocol for a randomized controlled trial

K. P. C. Dalpatadu, P. Galappatthy, P. Katulanda & S. Jayasinghe
Abstract Background Sri Lanka is faced with the challenge of managing a large population with diabetes mellitus by 2030. Psychological stress plays a major role in disease outcome by exerting physiological, psychological and social effects on individuals with chronic disorders. Meditation-based interventions have positive effects on the management of stress and diabetes, which are mediated via modulation of neuro-humoral mechanisms and autonomic functions, among others. Mechanisms of bio-physiological effects of meditation are considered to be...

Abstract Child and adolescent mental health (CAMH) are a global priority. Different countries across the globe face unique challenges in CAMH services that are specific to them. However, there are multiple issues that are also similar across countries. These issues have been presented in this commentary from the lens of early career CAMH professionals who are alumni of the Donald J Cohen Fellowship program of the IACAPAP. We also present recommendations that can be implemented...

Data from: Does mixed-species flocking influence how birds respond to a gradient of land-use intensity?

Christos Mammides, Jin Chen, Uromi Manage Goodale, Sarath Wimalabandara Kotagama, Swati Sidhu & Eben Goodale
Conservation biology is increasingly concerned with preserving interactions among species such as mutualisms in landscapes facing anthropogenic change. We investigated how one kind of mutualism, mixed-species bird flocks, influences the way in which birds respond to different habitat types of varying land-use intensity. We use data from a well-replicated, large-scale study in Sri Lanka and the Western Ghats of India, in which flocks were observed inside forest reserves, in ‘buffer zones' of degraded forest or...

Land-use and elevation interact to shape bird functional and phylogenetic diversity and structure: Implications for designing optimal agriculture landscapes

Rachakonda Sreekar, Xingfeng Si, Katerina Sam, Jiajia Liu, Salindra Dayananda, Uromi Goodale, Sarath Kotagama & Eben Goodale
Conversion of rainforests into agriculture resulted in massive changes in species diversity and community structure. Although the conservation of the remaining rainforests is of utmost importance, identifying and creating biodiversity-friendly agriculture landscape is vital for preserving biodiversity and their functions. Biodiversity studies in agriculture have often been conducted at low elevations. In this study, we compared the functional diversity (FD), phylogenetic diversity (PD), and community structure of birds along an interacting gradient of land-use (protected...
