Background:during human locomotion,a sufficiently stiff foot allows the ankle plantar flexors to generate large propulsive *** foot stiffness(e.g.,via a carbon plate)increases the ankle’s external moment arm in relation to the internal moment arm(i.e.,increasing gear ratio),reduces plantar flexor muscles’shortening velocity,and enhances muscle force *** contrast,when activation of the foot’s intrinsic muscles is impaired,there is a reduction in foot and.a.kle work and metatarsophalangeal joint *** speculated that the reduced capacity to actively control metatarsophalangeal joint stiffness may impair the gearing function of the foot at the ***:We used.a.tibial nerve block to examine the direct effects of the intrinsic foot muscles on ankle joint kinetics,in vivo med.a. gastrocnemius’musculotendinous dynamics,and.a.kle gear ratio on 14 participants during maximal vertical ***:Under the nerve block,the internal ankle plantar flexion moment decreased(p=0.004)alongside a reduction in external moment arm length(p=0.021)and.a.kle joint gear ratio(p=0.049)when compared to the non-blocked *** med.a. gastrocnemius muscle-tendon unit and fascicle velocity were not different between conditions,the Achilles tendon was shorter during propulsion in the nerve block condition(pddition to their known role of regulating the energetic function of the foot,our data indicate that the intrinsic foot muscles also act to optimize ankle joint torque production and leverage during the propulsion phase of vertical jumping.

Exotic plant invasion is a growing concern in the conservation and management of indigenous arid land ecosystems. By creating areas of ameliorated microclimates and fertile soil below their canopies, perennial plants might influence exotic annual plant invasions. We conducted.a.quantitative literature review of studies that compared exotic annual plant abundance among native perennial plant species and interspace （open areas） microsites in North America＇s Mojave desert, where exotic plant invasion has corresponded with increasing extent of wildfire and broad-scale ecosystem transformation. Ten studies compared exotic annual plant abundance between inter- spaces and below a total of 36 native perennial species. These studies revealed that：（1） With few exceptions, most native perennial species supported.a.greater abundance of exotic annuals than interspaces, indicating overall facilitation of exotic species by native perennials. （2） Exotic species abundance varied by orders of magnitude among native perennial species, with some perennial species harboring amounts of exotics similar to interspaces. （3） distributions of dominant exotic species varied, where Bromus rubens displayed.a.greater affinity for below-perennial microsites than did Schismus spp. and Erodium cicutarium that often were most abundant in interspaces. Results suggest that the degree of facilitation of exotic plants warrants consideration when selecting native perennial species for revegetation and restoration projects.

大概四分之一个世纪前,乔治·斯提尔(George Steel)只用四个字就在纽约古典音乐圈中掀起了一次革命,方法极为简单。当年他接管了哥伦比亚大学米勒剧院(Miller Theatre)后,将那个从前只搬演毫不起眼的演出季的场馆,彻底改造为一个充满活力、现代味浓厚的“无贝多芬地带”。当一个备受赞誉的音乐网站询问斯提尔吸引观众来看新作品演出的诀窍时,他回答道:“免费酒水!”
