Objective: To evaluate the impact of climate change on the distribution areas of 10 trees species characteristic of cloud forests in the state of Oaxaca. Materials and methods: The impact was evaluated for two-time horizons (2050 and 2080) and two emission scenarios (RCP 4.5 and 8.5) under the Had GEM2-ES general atmospheric circulation model. Current and future distribution was modeled with MaxEnt. The distribution of Carpinus tropicalis, Juglans pyriformis, Liquidambar styraciflua, Litsea glaucescens, Magnolia dealbata, Magnolia schiedeana, Ostrya virginiana, Symplocos coccinea, Zinowiewia concinna and Taxus globosa were obtained from the herbarium specimen review. Results and discussion: In RCP 4.5, J. pyriformis, L. styraciflua, L. glaucescens and S. coccinea increased (2.8 % to 20.5 %) their area of distribution. In this scenario, the rest of the species reduced their area by up to 30 % compared to the current distribution. In RCP 8.5-2050, J. pyriformis and O. virginiana had a gain of more than 5 %. All species showed a reduction greater than 10 % under the RCP 8.5-2080 scenario. The models showed area under the curve greater than 0.8 and partial ROC (Receiver Operating Characteristic) greater than 1.7. Conclusions: Understanding the response of 10 species to climate change will serve as a basis for proposing conservation and monitoring plans, since nine of them are in some category of risk.","PeriodicalId":54479,"journal":{"name":"Revista Chapingo Serie Ciencias Forestales Y Del Ambiente","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43812425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: To formulate a sawmill investment project for the Basihuare ejido, Guachochi, Chihuahua, and to evaluate its viability by estimating financial and economic indicators. Materials and methods: Projections of supply from 2020 to 2024 were made based on the records of roundwood inputs of the Pinus genus from 2015 to 2019. Sawmilling coefficients, sawn timber grade distribution and market price were determined with historical information from a private industry located in Guachochi.

Using the TIMESAT algorithm, 11 phenological variables per pixel and year were determined and the annual spatial average of each one was calculated for each type of land cover (pine, oyamel, shrubs and crops) and the cumulative increase of the extended integral (greening). Results and discussion: Mean temperature increased 0.87 °C in 2000-2019. Beginning, middle, and end of the season have occurred progressively earlier, and cumulative leaf area, as well as minimum and maximum LAI, have increased. Greening was recorded in 53.21 % of the MBBR and browning in 33.97 %.

For one year, 228 leaf mass measurements and 1 140 chemical determinations were made to determine needle stoichiometry. Measurements were subjected to a longitudinal analysis of variance, by testing trends over time (P < 0.05).Results and discussion: Needle production in JO were 67 % higher (11.2 Mg∙ha-1∙year-1) than in TL (6.7 Mg∙ha-1∙year-1); needle litterfall was higher during summer (June and July, months with higher precipitation). For JO, nutrient flux was 98.0, 5.2, 8.7, 24.6, and 5.6 kg∙ha-1∙year-1 for N, P, K, Ca, and Mg, respectively; for TL it was 55.3, 3.4, 7.8, 14.4, and 4.7 kg∙ha-1∙year-1 in the same order of nutrients.

Objective: To analyze the effect of traditional and controlled-release fertilizers, as well as the way to define the doses (technically or empirically), on growth of 20 tree families of Pinus patulaSchiede ex Schltdl. & Cham. Materials and methods: Four fertilization treatments were applied: 1) control; 2) “technical”, based on foliar analysis; 3) controlled release (18-6-12 + 2CaO + 3.5 Mg + 2.1 Si + microelements); and 4) mixture of agricultural fertilizers in nutrient concentrations similar to the controlled-release treatment. Height, diameter, biomass index, number of whorls, leaf mass, and growth initiation and cessation were evaluated in a group of 10 superior and 10 inferior three-year old families in Chignahuapan, Puebla. Data were analyzed with the MIXED procedure of SAS. Results and discussion: Trees showed no significant differences in growth, biomass production and growth initiation by fertilization effect, but showed significant differences by genetic quality (P ≤ 0.05). The genotype*fertilization interaction was significant; after one year of controlled-release fertilizer application, inferior genotypes had the highest values of relative rates of biomass production, diameter at root collar and height.

Objective: To compare composition, structure and diversity of temperate forest vegetation affected by different levels of severity of a forest fire in Jalisco. Materials and methods: Composition, horizontal structure, importance value index (IVI), diameter class, diversity indexes of Shannon, Simpson, Margalef richness and Bray-Curtis similarity were evaluated in three regions (Bosque La Primavera and Sierra de Tapalpa and Sierra de Quila) of temperate forest with three levels of severity (no fire, moderate and extreme). Results: Twelve species from six families were recorded. Pinaceae and Fagaceae were the most dominant. Dominance ranged from 0.2 to 50 m2∙ha-1 in moderate and extreme severity sites. Pinus devoniana recorded the highest IVI (71 %) in Sierra de Tapalpa. The highest number of trees was recorded in diameter class ≤30 cm. Diversity and richness indices showed significant differences (P < 0.05) for Sierra de Tapalpa and Sierra de Quila and among fire levels; the highest indices were recorded in sites of moderate severity. Tree composition similarity between regions was low (<33 %). Conclusions: Moderate severity of forest fire favored composition, structure and diversity of vegetation in temperate forests of Jalisco, indicating that the level of severity influences resilience of forest ecosystem communities.","PeriodicalId":54479,"journal":{"name":"Revista Chapingo Serie Ciencias Forestales Y Del Ambiente","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43273263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods: The phytochemical composition of ten extracts of Coffea arabica L. leaves cv. Catimor 5000 was evaluated in their phenolic and methylxanthines contents as well their antioxidant activity in vitro through nitric oxide (NO), absorbance capacity of oxygen radicals (ORAC), ferric reducing antioxidant power (FRAP), and radical ABTS (2,2'-azino-bis [3-ethylbenzothiazoline-6-sulfonic acid]) assays, and their effect on inhibition of oxidative stress induced by hydrogen peroxide in human colon adenocarcinoma cells (HT-29). Extracts were obtained by ultrasound assistance under different conditions (wave amplitude, solvent ratio, and extraction time). Results and discussion: The higher phenolics and caffeine contents, as well the greater oxidative stress inhibition response in the HT-29 model, ORAC and NO assays were obtained at 60/40 water/methanol, 40 % amplitude and 6 min of extraction time. In this work, identification of two flavanones have been reported for the first time in Coffea leaves: neohesperidin and naringenin.

Additive genetic variation, heritability (h2) and genetic and phenotypic correlations were calculated.Results and discussion: h2 were superior in the more fertile site. Height, whorls, straightness and volume had greater genetic control (0.09 < h2i < 0.18). h2i of stem straightness was higher when evaluated as a whole than when divided into three sections. Genetic correlations were high and positive among growth variables (rg > 0.81; diameter vs. volume = 0.99) and low to moderate for the rest. Volume had a higher genetic correlation with other traits and higher genetic variation and heritability, so it could be used as a selection criterion for breeding cycle.
