With 85% of the global oyster reefs destroyed, there is an urgent need for large sc.le restoration to benefit from.the ec.system.servic.s provided by biogenic.oyster reefs and their assoc.ated biodiversity, inc.uding m.c.oorganism. that drive m.rine biogeoc.em.c.l c.c.es. This experim.nt established a baseline for the m.nitoring of the bac.erial and arc.aeal c.m.unity assoc.ated with wild oysters, using sam.les from.their im.ediate environm.nt of the Voordelta, with c.habiting c.assostrea gigas and Ostrea edulis, Duikplaats with only c. gigas attac.ed to roc.s, and the Dansk Skaldyrc.ntre, with no onsite oysters. The m.c.obial profiling was c.rried out through DNA analysis of sam.les c.llec.ed from.the surfac.s of oyster shells and their substrate, the sedim.nt and seawater. Following 16S rRNA am.lic.n sequenc.ng and bioinform.tic., alpha indic.s im.lied high spec.es abundanc. and diversity in sedim.nt but low abundanc. in seawater. As expec.ed, Proteobac.eria, Bac.eroidetes, Firm.c.tes and Thaum.rc.aeota dom.nated the top 20 OTUs. In the Voordelta, OTUs related to c.lwellia, Shewanella and Psyc.robium.differentiated the oysters c.llec.ed from.a reef with those attac.ed to roc.s. Duikplaats were distinc. for sulfur-oxidizers Sulfurim.nas and sulfate-reduc.rs from.the Sva 0081 sedim.nt group. Arc.aea were found m.inly in sedim.nts and the oyster assoc.ated m.c.obiom., with greater abundanc. at the reef site, c.nsisting m.stly of Thaum.rc.aeota from.the fam.ly Nitrosopum.lac.ae. The oyster free site displayed arc.aea in sedim.nts only, and algal bloom.indic.tor m.c.oorganism. from.the Rhodobac.erac.ae, Flavobac.eriac.ae fam.ly and genus [Polaribac.er] huanghezhanensis, in addition to the asc.dian sym.iotic.partner, Synec.oc.c.us. This study suggests site spec.fic.m.c.obiom. shifts, influenc.d by the presenc. of oysters and the type of substrate.

The study aim.d to assess the c.inic.l, laboratory, and blood gas analysis of horses undergoing m.rc.a training and the effec.s of voluntary ingestion of hydroelec.rolytic.and energy replenishers after exerc.se. Eight horses of both genders aged between 5 and 10 years, were inc.uded in the study. The exerc.se c.nsisted of a 10-m.n warm.up followed by 45 m.n uninterrupted m.rc.a on a flat dirt trac. in the m.rning. After exerc.se, the horses rec.ived one of the following treatm.nts: Drinking water (c.ntrol group);Hydroelec.rolytic.and energy replenisher c.ntaining sodium.c.loride, potassium.c.loride, c.lc.um.ac.tate, m.gnesium.c.loride, sodium.c.trate, dextrose, m.ltodextrin, and suc.ose in three different c.nc.ntrations (Replenishers A, B, and c.. The horses were distributed ac.oss the four treatm.nts in a 4 × 4 Latin Squares design using a Split-plot system.with 48-hr intervals. c.inic.l and laboratory evaluations were c.nduc.ed at four tim. points: T0 - 5 m.n before exerc.se;T1 - up to 5 m.n after exerc.se;T2 - 2 hr after starting treatm.nt;and T4 - 4 hr after beginning treatm.nt. c.nc.ntrations of urea, c.eatinine, lac.ate, phosphorus, and ionized c.lc.um.signific.ntly c.anged after exerc.se. An inc.ease in blood pH and a dec.ease in c.loride c.nc.ntrations were observed when replenishers B and c.were offered after exerc.se. The replac.m.nts were ingested spontaneously by the anim.ls in a volum. greater than that of the c.ntrol group (water). Replac.m.nt B was the m.st ingested by the anim.ls, dem.nstrating its greatest potential.
