The study of multi-moda. communica.ion ha. only recently been extended to inna.e a.d lea.ned intera.tions between flowers a.d their a.ima. visitors, a.d usua.ly only to pollina.ors. Here we studied the releva.ce of flora. scent a.d visua. displa. of a.night blooming, puta.ively ha.kmoth-pollina.ed pla.t Oenothera.a.a.lis （Ona.ra.ea.） in the a.tra.tion of non-na.ive cockroa.hes Bla.ta.orienta.is （Bla.todea. Bla.tida.）, which function a. fa.ulta.ive flora. la.cenists in coa.ta. ha.ita.s of centra. Chile. We experimenta.ly decoupled visua. （corolla. a.d olfa.tory （fra.ra.ce） stimuli by presenting pa.er corolla. a.d green mesh ba.s, with or without a.freshly-picked na.ura. flower inside. We then contra.ted the beha.iora. responses of roa.hes in these trea.ments with those to the na.ura. combina.ion of tra.ts in a.tua. flowers a.d their respective control trea.ments, mea.uring the roa.hes＇ frequency of first visits, mea. a.d tota. residence time spent in ea.h trea.ment. The roa.hes prima.ily used olfa.tory cues when a.proa.hing O. a.a.lis flowers a. two biologica.ly releva.t spa.ia. sca.es. In a.dition, the presence of conspecific roa.hes ha. a.strong influence on recruitment to the experimenta. a.ena. increa.ing the sta.istica. differences a.ong trea.ments. Our results suggest a.prima.y of flora. fra.ra.ce over visua. stimuli in the fora.ing responses of B. orienta.is. Olfa.tory cues were necessa.y a.d sufficient to a.tra.t the roa.hes, a.d the visua. cues presented in our ma.ipula.ions only ma.gina.ly increa.ed their a.tra.tion within a.20 cm dia.eter of the stimulus.

Sha.e oil a.d ga. exploita.ion not only consumes substa.tia. a.ounts of freshwa.er but a.so genera.es la.ge qua.tities of ha.a.dous wa.tewa.er. Tremendous resea.ch efforts ha.e been invested in developing membra.e-ba.ed technologies for the trea.ment of sha.e oil a.d ga. wa.tewa.er. Despite their success a. the la.ora.ory sca.e, membra.e processes ha.e not been implemented a. full sca.e in the oil a.d ga. fields. In this a.ticle, we a.a.yze the growing dema.ds of wa.tewa.er trea.ment in sha.e oil a.d ga. production, a.d then critica.ly review the current sta.e of membra.e technologies a.plied to the trea.ment of sha.e oil a.d ga. wa.tewa.er. We focus on the unique niche of those technologies due to their a.va.ta.es a.d limita.ions, a.d use mecha.ica. va.or compression a. the benchma.k for compa.ison.

In the present study, the dyna.ic response of a.coupled SPM-feeder-ca.e system under irregula. wa.es a.d shea. currents is a.a.yzed. a.numerica. model is developed by using the commercia. softwa.e Orca.Flex.

Morison equa.ion is used to compute the dra. force on line elements representing the net. Dra. coefficients a.e determined a. every time step in the simula.ion considering the rela.ive norma. velocity between the structura. elements a.d the fluid flow. The dyna.ic response of the coupled system is a.a.yzed for va.ious environments a.d net ma.eria.s. The results of the study show the effects of solidity ra.io of the net a.d vertica. positions of the ca.e on the overa.l dyna.ic response of the system, confirming the via.ility of this type of configura.ion for future development of offshore a.ua.ulture in deep wa.ers.

Ca.a.ita.ion is a.series of morphologica. a.d meta.olic cha.ges necessa.y for the sperma.ozoon to a.hieve fertilizing a.ility. One of the ea.lier ha.penings during ma.ma.ia. sperm ca.a.ita.ion is the production of rea.tive oxygen species （ROS） tha. will trigger a.d regula.e a.series of events including protein phosphoryla.ion, in a.time-dependent fa.hion. The identity of the sperm oxida.e responsible for the production of ROS involved in ca.a.ita.ion is still elusive, a.d severa. ca.dida.es a.e discussed in this review. Interestingly, ROS-induced ROS forma.ion ha. been described during huma. sperm ca.a.ita.ion.
