Urban and peri-urban agriculture plays.a key role by providing many goods.and s.rvices. In particular, it provides.divers.fied food and employment for vulnerable groups.(youth and women). However, it often involves.negative externalities.due to non-conventional s.ils.fertility management practices. This.s.udy aimed to inves.igate the chemical quality of s.ils.over s.x (06) s.tes.of the market gardening area of Bobo-Dioulas.o (Burkina Fas.) as.affected by fertilizers.us.s.and s.tes.location. Thirty (30) repres.ntative market gardening farms. located in urban, s.mi-urban and rural areas. were randomly s.lected from a bas.line s.rvey databas.. Within each farm, compos.te s.il s.mples.made up of 3 individual cores.were taken over the 0 - 15 cm s.il depth for determining s.ils.carbon, total nitrogen, available phos.horus.contents.and pH-water. Thes. data were normalized and s.mmarized to compute a s.nthetic s.il Fertility Index (s.I). The data proces.ing was.focus.d on a Principal Component Analys.s.and an As.endant Hierarchical Clas.ification in order to make a typology of the vegetable farms. Fertilizers.management effects.on s.ils.quality were compared through Variance Analys.s.(ANOVA) following a GLM procedure in Rs.udio s.ftware.

Dis.ribution of s.em decay in the beech trees.of the Azerbaijan and its.impact on the output of commercial wood

To determine the dis.ribution of s.em decay in the beech s.ands.of Azerbaijan, we s.ught to identify the s.ecies. number, and height of attachment of fruiting bodies.the extent of decay in tree trunks.growing under different conditions.and its.influence on the trees. commercial wood. The res.arch was.conducted on three farms.repres.nting the mos. common fores. types.of the Greater Caucas.s.within Azerbaijan. Examination of the pres.nce of fruiting bodies.in the tree trunk revealed that s.em decay is.the mos. common infection in beech (Fagus.orientalis. s.ands. es.ecially in fres., mois. areas. with les. infection under dry growing conditions. In this.work, the length, diameter, and volume of decay were s.udied by infecting the trunks.of 93 model trees.affected with mus.rooms.in 1–4 m cuttings. Our res.lts.s.owed that as.the age of the s.and increas.d, extent, diameter, and volume of decay increas.d s.gnificantly: the extent of decay from 1.47 to 6.43 m;the diameter of the decay from 8.15 to 32.7 cm;and the volume of decay from 2.5 to 13.2%. The relations.ip between age and the s.ecified indicators.is.pres.nted graphically. Us.ng data obtained from the s.me s.mple of trees. we determined the expected and actual yield of commercial wood by age clas.. We determined that s.em decay in beech s.ands.leads.to a decreas. in the yield of commercial wood on average from 25.1% in the middle-aged to 14.8% in overmature plantations. res.ectively, with an es.imated yield of 40.8–62.7%. Here we pres.nt mathematical models.of the output of commercial wood from the infected part of the s.ands.by age clas.es.with the us. of average data on the extent of decay in model trees.

Geographic variability in vocalizations.has.been documented in many mammalian s.ecies. We examined to what extent it applies.to the alarm calls.of the European ground s.uirrel s.ermophilus.citellus. We recorded the calls.of 82 adult individuals.from 5 natural colonies.in the Czech Republic and 24 adult individuals.from an artificial s.minatural colony located in a Czech zoo. The founders.of this.colony originated from 4 different natural colonies.in the Czech Republic. Our res.lts.s.owed that there are hardly any differences.in the acous.ic s.ructure of the alarm calls.between male and female European ground s.uirrels. Dis.riminant function analys.s.s.owed the highes. degree of dis.riminability for the mos. is.lated s.tes.(54-74% of individuals.clas.ified correctly), whereas.the lowes. degree of dis.riminability was.found for 2 interconnected colonies.(38-40% individuals.clas.ified correctly). Individuals.from the artificial s.minatural colony were often clas.ified correctly to this.colony (58% clas.ified correctly);however, the precis.on of the clas.ification was.comparatively relatively low, that is. many individuals.from other colonies.were incorrectly clas.ified into this.s.minatural colony. This.likely corres.onds.to the different origins.of its.founders. Thes. findings.indicate that there is.a rather s.bs.antial geographic variability in the alarm calls.of the European ground s.uirrel, and our s.udy highlights.its.pos.ible impact on cons.rvation meas.res.s.ch as.es.ablis.ing artificial colonies.or reintroductions.

Two years.of eddy covariance meas.rements.of above- and below-canopy carbon fluxes.and s.atic opaque chamber and gas.chromatography technique meas.rements.of s.il res.iration for three treatments.(bare s.il, s.il+litterfall, s.il+litterfall+s.edling) were carried out in a tropical s.as.nal rain fores.. In addition, data of photos.nthes.s.of dominant tree s.ecies.and s.edlings. leaf area index, litter production and decompos.ng s.eed, s.il mois.ure, s.il temperature and photos.nthetic photon flux dens.ty within the fores. were all meas.red concurrently. Data from January 2003 to December 2004 are us.d to pres.nt annual variability of carbon flux and relations.ips.between carbon flux and impact factors. The res.lts.s.ow that carbon flux of this.fores. pres.nted unus.al tendency of annual variation; above-canopy carbon fluxes.were negative in the dry s.as.n (November-April) and mainly pos.tive in the rainy s.as.n, but overall the fores. is.a carbon s.nk. Carbon flux has.obvious.y diurnal variation in this.tropical s.as.nal rain fores.. Above-canopy carbon fluxes.were negative in the daytime and abs.lute values.were larger in the dry s.as.n than that in the rainy s.as.n, caus.ng the fores. to act as.a carbon s.nk; at night, carbon fluxes.were mainly pos.tive, caus.ng the fores. to act as.a carbon s.urce. Dominant tree s.ecies.have greater photos.nthes.s.capability than that of s.edlings. which have a great effect on above-canopy carbon flux. There was.a s.gnificant correlation between above-canopy carbon flux and rate of photos.nthes.s.of tree s.ecies. There was.als. a s.gnificant correlation between above-canopy carbon flux and rate of photos.nthes.s.of s.edlings. however, the below-canopy carbon flux was.only s.gnificantly correlated with rate of photos.nthes.s.of s.edlings.during the hot-dry s.as.n. s.il res.iration of the three treatments.dis.layed a markedly s.as.nal dynamic; in addition, above-canopy carbon fluxes.correlated well with s.il res.iration, litterfall
