Twenty- one morphometric traits from 770 local chickens (412 hens, 358 cocks) were measured and analyzed using the PROC GLM of SAS 2008. Tukey mean comparison was used to analyze significantly different traits. Correlation analysis was used to determine the relationships among the traits. Significant variations were found in most traits among ecotypes, with males showing higher values in many traits. Kolla chickens generally exhibited higher values, except for neck length, skull length, and wattle, earlobe, comb, and beak indices. Interactions between sex and ecotypes significantly affected the morphometric traits. The strength and direction of significant correlations among the quantitative traits varied across the chicken ecotypes and sexes. The variation in morphometric measurements among the chicken ecotypes is an indicator of genetic diversity in the study area, calling for a community-centered holistic genetic enhancement program.\u0000","PeriodicalId":383132,"journal":{"name":"Ecology and Evolutionary Biology","volume":"32 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141814261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite of, its importance the crop it is affected by many biotic stresses such as pest and diseases attack. Grey leaf spot, caused by Cercospora Zeae maydis is the most important foliar disease of maize. The disease is characterized by relatively rapid leaf necrosis and premature death of foliage which eventually reduces grain yield. Development of host resistance to this disease can provide an important component of integrated disease management; which is the most effective and practical method of managing maize disease. The study was conducted to evaluate the reaction of maize inbred lines to GLS in the main cropping season during 2020. The inbred lines were obtained from Bako National Maize Research Center, breeding program, and it was arranged using alpha-lattice design with two replications. The inbred lines were evaluated in GLS screening field under artificial inoculation at Bako West Shewa, Ethiopia. Plot based Disease severity scores (1-5 scale) was used to assess at ten days intervals from disease onset to maturity. All the inbred lines showed disease symptom during the season, but the intensity of the diseases differed significantly at (P<0.05) among the inbred lines. Out of 72 genotypes screened for GLS, 20 inbred lines viz. BKL002, BKLOO4, CML 165, MBRC5BCF108-2-3-1, TZMI746, TZMI719, TZMI733, CML547, CML543, CML536, CZLQ1, CZLQ2, CML511, ILO'00E-5-5-3-1-1, 30H83-7-1-3-1-1-1-1, TZMI750, TZMI763, 30H83-7-1-2-1-1-1-#-#, DE-38-Z-126-3-2-2-2-1-1-#, TZMI407-short-#-#-# were identified to be resistant whereas TZMI746 and CML536 inbred lines are suitable candidates for utilization in both grain yield and GLS resistance, thus recommended for inclusion in hybrid development programs.\u0000","PeriodicalId":383132,"journal":{"name":"Ecology and Evolutionary Biology","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141126932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, new management programs have been underway that use current hatchery facilities for the restoration of native forage fishes in Lake Ontario. These species include Bloater (Coregonus hoyi), which has been extirpated from Lake Ontario for approximately four decades, and Cisco (C. artedi), which exists at a fraction of its former abundance. We assessed morphometrics, length-weight relationships, and condition factors during early life development for eight cohorts of Cisco and Bloater reared from 2012-2019. Weekly samples for Cisco and Bloater were measured from hatch until release (29-45 weeks, 133-1,002 samples annually). Head width, gape, mandible length, and mouth height metrics were all larger for Cisco than Bloater at any given size but increased at similar rates for both species. Average condition factors for Cisco and Bloater were 0.54317 and 0.55892, respectively. This information may also improve field identification of these species, helping managers evaluate the relative success of different release strategies for rehabilitation of populations of these native species.\u0000","PeriodicalId":383132,"journal":{"name":"Ecology and Evolutionary Biology","volume":"155 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140247237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty three plant species, disperse into 23 families, were recorded in the study area from highland, lowland and midland Homegarden agroforestry. The Myrtaceae family is the dominant with 6 species, subsequently Fabaceae and Euphorbiaceae family with 5 species. From this finding result, midland agro ecology has a at great height number of plant species per home garden than other agro ecologies. Research design was used to gather data focused on smallholder homegarden agroforestry. It is acclimated describe homegarden agroforestry composition and diversity. One-way ANOVA was applyed to analyze data to compare as well as identify statistically difference between three agro-ecologies. The Shannon diversity index revealed that the midland woody species diversity index (H’=2.94) was higher than the highland (H’=2.91) and lowland (H’=2.89). According to Sorensen's similarity coefficient out of the three home gardens, midland and highland have agreat number of species compositions in common (76%). A relatively low similarity was perceived between highland and lowland. Awareness is required by concerned individuals to keep the multispecies farming system that contribute s more diversity of native plant species of this system.","PeriodicalId":383132,"journal":{"name":"Ecology and Evolutionary Biology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132225968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
