Correlation, multiple regression, and path analyses w.re used to investigate the relationships betw.en body w.ight and three other morphological traits in juvenile Japanese sea cucumbers Apostichopus japonicus . w. measured live body w.ight (Bw., body length (BL), numbers of papillae (NP), and numbers of tube feet (NF) at 60, 80, 100, and 130 days post-hatching (dph). w. calculated path correlation coefficients, correlation indices ( R 2 ), and coefficients of determination w.th Bw.as the dependent variable and the other morphological traits as independent variables. The coefficient of variation for Bw.w.s high across all age groups, and all measured morphological traits w.re significantly correlated ( P w.across all age groups (60 dph, 0.526;80 dph, 0.404;100 dph, 0.620;and 130 dph, 0.681), w.ile NF had the greatest indirect eff ect on Bw.across all age groups (60 dph, 0.528;80 dph, 0.452;100 dph, 0.666;and 130 dph, 0.603). Regression analyses betw.en morphological traits and Bw.indicated that R 2 w.s greater than 0.85 only in the 100-dph specimens. The indirect eff ects of the other measured morphological traits on Bw.w.re age-dependent. The optimal regression equations, as determined w.th stepw.se regression, w.re, for 60-dph specimens: Bw.60 =10 (-3.04+0.092BL+0.014NP+0.014NF)( R 2 =0.632);for 80-dph specimens: Bw.80 =10 (- 3.035+0.056BL+0.017NP+0.02NF)( R 2 =0.686);for 100-dph specimens: Bw.100 =10 (- 3.742+0.069BL+0. 633 · lg (NP)+0. 464 · lg (NF))( R 2 =0.893);and for 130-dph specimens: Bw.130 =10 (- 2.472+0.065BL+0.012NP)( R 2 =0.774). Our w.rk clarified the correlation betw.en various morphological traits and body w.ight of a commercially-important sea cucumber species ( A . japonicus ). Our predictive models for body w.ight might be useful for the aquaculture and selective breeding of A . japonicus .

Massive geological landslides and unstable landslide areas w.re triggered by the 2008 w.nchuan earthquake. These landslides caused deaths, damaged infrastructure and threatened endanger species. This study analyzed the impact of landslides on giant pandas and their habitats from the follow.ng aspects: threatening pandas‘ lives, damaging pandas‘ habitat, influencing giant panda behavior, increasing habitat fragmentation; the final aspect, and blocking gene flow.by cutting off corridors. A habitat suitability map w.s created by integrating the landslide factors w.th other traditional factors based on a logistics regression method. According to the landslide inventory map, there are 1313 landslides, 818 rock debris flow., 117 rock avalanches and 43 mud flow. occurred in the study area. A correlation analysis indicated that landslides caused the pandas to migrate, and the core landslides w.thin 1 km2 had greater influence on panda migration. These core landslides primarily occurred in mid-altitude regionscharacterized by high slopes, old geological ages, large areas and large rock mass volumes. The habitat suitability assessment results for the w.long Natural Reserve had better prediction performance(80.9%) and demonstrated that 14.5%, 15.9%, 20.5%, 47.6% and 1.5% of the study area can be classified as very high, high, moderate, low.and very low.giant panda suitability areas, respectively. This study can be used to inform panda and panda habitat research, management and protection during post-quake reconstruction and recovery periods in China.

On April 20, 2013, an earthquake w.th mag- nitude 7.0 occurred in the southw.st of the Longmenshan fault system in and around Lushan County, Sichuan Province, China. This devastating earthquake killed hun- dreds of people, injured 10 thousand others, and collapsed countless buildings. In order to analyze the potential risk of this big earthquake, w. calculate the co- and post-seismic surface deformation and gravity changes of this event. In this w.rk, a multilayered crustal model is designed, and the elastic dislocation theory is utilized to calculate the co- and post-seismic deformations and gravity changes. During the process, a rupture model obtained by seismic w.veform inversion （Liu et al. Sci China Earth Sci 56（7）： 1187-1192, 2013） is applied. The time-dependent relaxation results show.that the influences on Lushan and its surrounding areas caused by the Ms7.0 Lushan earthquake w.ll last as long as 10 years. The maximum horizontal displacement, vertical uplift, and settlement are about 5 cm, 21.24 cm, and 0.16 m, respectively; the maximal positive and nega- tive values of gravity changes are 45 and -0.47 μGal, respectively. These results may be applied to evaluate the long-term potential risk caused by this earthquake and to provide necessary information for post-earthquake reconstruction.

AIM To verify the hypothesis that the Ling classification describes the endoscopic progressive process of achalasia and determine the ability of successful peroral endoscopic myotomy (POEM) to prevent endoscopic progression of achalasia. METHODS w. retrospectively review.d the endoscopic findings, symptom duration, and manometric data in patients w.th achalasia. A total of 359 patients (197 w.men, 162 men) w.th a mean age of 42.1 years (range, 12-75 years) w.re evaluated. Symptom duration ranged from 2 to 360 mo, w.th a median of 36 mo. Patients w.re classified w.th Ling type I (n = 119), II a (n = 106),II b (n = 60),II c (n = 60), or III (n = 14), according to the Ling classification. Of the 359 patients, 349 underw.nt POEM, among w.om 21 had an endoscopic follow.up for more than 2 years. Pre-treatment and post-treatment Ling classifications of these 21 patients w.re compared. RESULTS Symptom duration increased significantly w.th increasing Ling classification (from I to III) (p w.ereas low.r esophageal sphincter pressure decreased w.th increasing Ling type (from I to III) (p w.s no difference in sex ratio or onset age among the Ling types, although the age at time of diagnosis w.s higher in Ling types I c and III than in Ling types I, IIa, and I b. Of the 21 patients, 19 underw.nt high-resolution manometry both before and after treatment. The mean preoperative and postoperative low.r esophageal sphincter pressure w.re 34.6 mmHg (range, 15.3-59.4 mmHg) and 15.0 mmHg (range, 2.1-21.6 mmHg), respectively, indicating a statistically significant decrease after POEM. All of the 21 patients w.re treated successfully by POEM (postoperative Eckardt score w.up period of 37.8 mo (range, 24-51 mo). CONCLUSION The Ling classification represents the endoscopic progressive process of achalasia and may be able to serve as an endoscopic assessment criterion for achalasia.
