Detangling the Effects of Environmental Filtering and Dispersal Limitation on Aggregated Distributions of Tree and Shrub Species: Life Stage Matters.

The pervasive pattern of aggregated tree distributions in natural communities is commonly explained by the joint effect of two clustering processes: environmental filtering and dispersal limitation, yet little consensus remains on the relative importance of the two clustering processes on tree aggregations. Different life stages of examined species were thought to be one possible explanation of this disagreement, because the effect of environmental filtering and dispersal limitation are expected to increase and decrease with tree life stages, respectively. However, few studies have explicitly tested these expectations.

[Applicability analysis of spatially explicit model of leaf litter in evergreen broad-leaved forests].

The spatially explicit model of leaf litter can help to understand its dispersal process, which is very important to predict the distribution pattern of leaves on the surface of the earth. In this paper, the spatially explicit model of leaf litter was developed for 20 tree species using litter trap data from the mapped forest plot in an evergreen broad-leaved forest in Tiantong, Zhejiang Pro- vince, eastern China. Applicability of the model was analyzed.

[Evaluation on effect of treatment and assistance to advanced schistosomiasis patients in Hunan Province from 2004 to 2013].

Objective: To comprehensively evaluate the effect of the program of treatment and assistance to advanced schistosomiasis patients in Hunan Province from 2004 to 2013.

Methods: The fund investment of the program, the profits of hospitals and the improvement of the patients' health were investigated by data collection and questionnaire survey. The evaluation index system of treatment and assistance to advanced schistosomiasis in Hunan Province was constructed by the Delphi method and analytic hierarchy process, and the program was assessed comprehensively.

[Multi-disciplinary treatment for advanced schistosomiasis].

Objective: To assess the efficiency of multi-disciplinary treatment (MDT) for advanced schistosomiasis.

Methods: A total of 173 advanced schistosomiasis patients who received MDT were selected from January 2010 to December 2011. These patients included 75 splenomegaly cases and 98 ascites cases.

[Retrospective survey of 184 patients infected with Schistosoma haematobium from African countries].

Objective: To understand the status of persons of export of labor services infected with Schistosoma haematobium.

Methods: A total of 184 suspected hospitalized patients infected with S. haematobium were investigated retrospectively.
