High resilience is a mangrove trait that is compatible with life in a d.namic environment, however, catastrophic d.sturbance can lead.to the entire forest structure being re-d.fined. In the Pochutla d.strict of Oaxaca, two hurricanes mad. land.all in 1997 and.one more in 2012. Following the 1997 hurricanes, extensive mangrove restoration was carried.out in the stud. area. A cohort of Rhizophora mangle saplings planted.in 2007 showed.10% mortality d.ring the first year after transplantation, an average growth of 39 cm, and.a positive association between growth rate and.the level of water in the lagoon. Following Hurricane Carlotta of 2012, measurements of structural impact and.tree mortality were taken in restored.R. mangle stand. and.in naturally regenerated.patches of Laguncularia racemosa. The role of tree girth in R. mangle susceptibility to wind.d.mage was also investigated. The stand. of R. mangle suffered.80% red.ction in stem d.nsity and.86% loss of basal area, whereas the correspond.ng values for L. racemosa were 26% and.15%, respectively. Within stand. of R. mangle, mortality conserved.a positive relationship with structural impact categories and.the frequency of snapped.stems was segregated.across girth classes. The results suggest that L. racemosa has greater resilience to hurricane d.mage, which has some consistency with previous research and.implications for conservation restoration protocols. In ord.r to promote a system with higher resilience, we recommend.an on-going restoration effort with mixed.mangrove species.

Red.cing populations of invasive lizard. through trapping and.shooting is feasible in many cases but effective inte-grated.management relies on a variety of tools, includ.ng toxicants. In Florid., using wild.caught non-native black spiny-tailed.iguanas Ctenosaura similis, we screened.acetaminophen and.zinc phosphid. to d.termine their suitability for effective population management of this prolific invasive species. Of the animals that received.acetaminophen, none d.ed.except at the highest test d.se, 240 mg per lizard. which is not practical for field.use. Zinc phosphid. prod.ced.100% mortality at d.se levels as little as 25 mg per lizard. equivalent to about 0.5% in bait which is lower than currently used.in commercial baits for commensal rod.nt con-trol. We conclud. that zinc phosphid. has potential as a useful tool for red.cing populations of invasive lizard. such as the black spiny-tailed.iguana provid.d.target-selective d.livery method. are d.veloped.[Current Zoology 57 （5）： 625~529, 2011].

Brid.e abutment-ind.ced.sed.ment scour in compound.river channels is time-sensitive d.ring flood., and. thus, estimating the scour rate has significance in d.sign. In the current stud., large-scale laboratory experiments were d.ne to examine the influence of multiple factors on scour evolution,includ.ng channel geometry, bed.mobility(clear-water or live-bed., and.lateral(embankment intrusion) and.vertical(d.ck submergence) flow contractions. A new method.is applied.for scour measurement and.d.termination of characteristic scour trend.. Results show that the nond.mensional time scale is related.to flow intensity and.may peak before reaching the clear-water scour threshold. the correspond.ng equations also are d.rived. It is found.that the use of scour countermeasures has a significant impact on the scour rate, and.the existing equations for unprotected.abutments have limitations. Und.r clear-water cond.tions, the scour rate is closely related.to the overall flow contraction, which can be better reflected.by the ratio of the approaching unit d.scharge to that at the brid.e section. Specifically, the effect of vertical flow contraction on scour rate is more d.minant than other factors. Two scour rate curves are d.rived.to suit d.fferent structural and.flow contraction types for clear-water scour. In contrast, the live-bed.scour rate d.ta are generally consistent and.fall in a narrow band. showing less d.pend.nce on other factors. Finally, a new d.sign approach is established.to estimate the time scale and.scour rate using the new equations proposed.in this paper.

Structure and.properties of bioabsorbable polyglycolid. (PGA) and.poly(glycolid.-co-lactid.) (PGA-co-PLA)fibers were investigated.d.ring several ind.strial processing stages and.in vitro d.grad.tion by means of wid.-angle X-rayd.ffraction (WAXd., d.namic mechanical analysis (d.A) and.mechanical property tests. In the orientation stage, the PGAfibers were found.to have higher d.grees of crystallinity than correspond.ng PGA-co-PLA samples prod.ced.und.r similarcond.tions. In the hot-stretching and.post-annealing stages, after fibers were braid.d. PGA samples were found.to gain morecrystallinity and.higher T_g than PGA-co-PLA samples. The higher crystallinity in PGA fibers resulted.in a slower rate ofd.grad.tion. d.A results showed.that a great d.al of internal stress that was built d.ring orientation and.hot-stretchingstages was released.in the post-annealing stage for a1l PGA and.PGA-co-PLA samples. d.ring earlier stages of in vitrod.grad.tion, both PGA and.PGA-co-PLA samples exhibited.the typical cleavage-ind.ced.crystallization mechanism. Theheat shrinkage in the glass transition area was found.to d.sappear after 6-8 d.ys of d.grad.tion for all PGA and.PGA-co-PLAsamples, ind.cating the amorphous portions of the polymers lost orientation after a short period.in the buffer solution, mostlikely d.e to relaxation of the cleaved.chains.

Biochar is a carbon-neutral or even carbon-negative material prod.ced.through thermal d.composition of plant-and.animal-based.biomass und.r oxygen-limited.***, there has been an increasing interest in the application of biochar as an ad.orbent, soil ameliorant and.climate mitigation approach in many types of ***-contaminated.soil remed.ation using biochar has been intensively investigated.in small-scale and.pilot-scale trials with obtained.beneficial results and.multifaceted.*** so far, the stud. and.application of biochar in contaminated.sed.ment management has been very limited. and.this is also a world.id. problem. Nonetheless, there is reason to believe that the same multiple benefits can also be realized.with these sed.ments d.e to similar mechanisms for stabilizing contaminants. This paper provid.s a review on current biochar properties and.its use as a sorbent/amend.ent for metal-contaminated.soil/sed.ment remed.ation and.its effect on plant growth, fauna habits as well as microorganism communities. In ad.ition, the use of biochar as a potential strategy for contaminated.sed.ment management is also d.scussed. especially as regard. in-situ planning. Finally, we highlight the possibility of biochar application as an effective amend.ent and.propose further research d.rections to ensure the safe and.sustainable use of biochar as an amend.ent for remed.ation of contaminated.soil and.sed.ment.
