El objetivo fue comparar los parámetros de comportamiento productivo e ingestivo ovinos alimentados en sistemas silvopastoriles y confinamiento. Se evaluaron consumos materia seca (CMS), orgánica (CMO), proteína cruda (PC) fibra detergente neutro (CFDN), la ganancia diaria peso (GDP), el tiempo dedicado al consumo (TPC), a rumia (TPR), caminar (TPCM) otras actividades (TPOA), 18 con inicial 16.83 ± 2.57 kg, distribuidos un diseño completamente azar, tres tratamientos: dos tipos (SSP): 1)...
El objetivo del presente estudio fue evaluar la actividad acaricida de extractos etanólicos tres genotipos Leucaena spp: L. leucocephala (Lam.) Wit (Nativa), (Cunningham) y Leucocephala x padilla (KX2), sobre larvas garrapatas adultas Rhipicephalus microplus. Para se usaron las pruebas inmersión e adultas. Asimismo, en los spp. analizó el perfil metabolitos secundarios mediante placas analíticas cromatografía. Los a concentración 50 % mostraron una mortalidad 91.68, 82.00 54.06 para...
According to records available in the literature, 380 species of fungi and fungus-like organisms are known for state Quintana Roo on Yucatán Peninsula Mexico. We carried out mycological surveys this state, following classical methods collecting, describing, curating macrofungi. As a result our research, 21 recorded first time Roo, Amanita arenicola O. K. Milller & Lodge, Inocybe xerophytica Pegler, Russula cremeolilacina Pegler The distinctive characteristics photographs...
<p><em>Alsophila firma</em> is a tree fern that distributed mainly in tropical montane cloud forest (TMCF) and considered as threatened species. Arbuscular mycorrrhizal fungi (AMF) have been proposed an alternative rescue programs of endangered However, our knowledge about diversity AMF mycorrhizal status the species TMCF limited. In Mexico shows different degrees conservation because fragmentation land use change. this study, we evaluated level colonization, richness...
<p><strong>Background.</strong> The mutualistic interaction with Arbuscular Mycorrhizal Fungi (AMF) is one of the main strategies used by plants to improve their absorption nutrients and cope adverse environmental conditions. They are ubiquitous microorganisms that help maintain soil health crop nutrition, which why they considered an essential component in agroecosystems. However, its presence affected multiple biotic abiotic factors such as tree cover management...
Agaricus is one of the most diverse genera within basidiomycetes with more than 600 described species. subg. Minoriopsis includes two sections, A. sect. Kerrigania and Minoriopsis, species that have a preferential distribution in (sub-)tropical areas exclusively Americas. So far, diversity little studied Mexico. With our continuing surveys regions Mexico, some its hidden has come to light. In this paper, we describe new Minoriopsis: calolepidotus xalapensis, using combined approach...
Species of the genus Lactarius subsection Scrobiculati are distributed in northern hemisphere and associated with temperate forests. In Mexico, four species two varieties this have been reported; however, their identification is complex due to morphological variability lack DNA sequences phylogenetic analysis. This study describes illustrates alnicola L. mexicanus Abies religiosa forests through The ITS were deposited GenBank (MF040818 MH820031). morphology both matches original...
We evaluated the effect of different dietary Tithonia diversifolia (TD: 0, 10, 20, and 30 %) on productive traits, egg quality, economic efficiency in laying hens. Feed intake was higher hens fed 20 % TD diets (120.6 119.0 g/day) compared with those 0 or 10 (P < 0.0010). weight conversion increased inclusion The rate 0.0020) (94.5 94.6 %, respectively) than (89.7 84.9 %). Eggs yolks were heavier diet <0.0020 P 0.0040, respectively), which also had poorer albumen width yolk a more...
Antecedentes y Objetivos: El género Melanogaster se caracteriza por su hábito hipogeo a semi hipogeo, basidiomas parduscos, gleba con lóculos llenos de gel basidiosporas globosas elipsoides. distribuye en zonas templadas, pero secuencias ectomicorrizas Coccoloba pocas colecciones han revelado presencia los trópicos. objetivo este artículo es describir una nueva especie partir datos ecológicos, moleculares morfológicos. Métodos: Los especímenes fueron recolectados jardines urbanos Quintana...

 Respuesta de plántulas Cedrela odorata a la inoculación con Rhizophagus intraradices y diferentes niveles defoliación ; el efecto seis tratamientos (T) sobre tasa crecimiento en altura (TCA) , diámetro ( TCD ) relativo (TCR peso fresco seco C. se evaluaron un vivero. Se utilizó diseño completamente al azar arreglo factorial (2 x 3); TS consistió una combinación los factores: porcentaje (0, 50 90) R. (con sin inoculación). Después meses, las inoculación, independientemente...
Las poblaciones endémicas de Abies religiosa (abeto, oyamel) poseen gran importancia económica, ecológica y social; además, forman distintas interacciones con microorganismos edáficos, principalmente hongos ectomicorrizógenos. Actualmente, las aisladas (i. e. están amenazadas por la deforestación, expansión agrícola el calentamiento global; lo cual, es urgente entender ecológicas evolutivas El objetivo presente investigación fue analizar uso ecología, taxonomía biología molecular...
The objective was to evaluate the production and nutritional composition of cassava (Manihot esculenta Crantz) meal under dierent organic fertilization rates. Twenty 10 m plots were planted with fertilized 0.0, 0.5, 1.0 1.5 kg plant-1 sugarcane lter cake (part waste left after processing). variables measured fresh dry forage yield (FFY DFY), tuber (FTY DTY), (MY) their composition. results indicate that signicantly increased FFY, DFY, FTY, DTY MY compared control. Applying fertilizer...
Sphingidae is an important component contributing to ecological functions in the tropics. However, studies and inventories are scarce. The diversity of nocturnal hawk moths a fragment tropical semi-deciduous forest (TSDF) at central Veracruz, Mexico were described. A 250-watt mercury-vapor lamp was used nocturnally for collection each month 1 year. Collection during night new moon from 1800 0600 hours. Diversity correlated moth richness abundance with mean temperature rainfall. In total, 178...
El inadecuado manejo de Tithonia diversifolia puede ocasionar una disminución progresiva en la producción forraje (Ruiz et al., 2012)
Aim of study: (i) To investigate the diversity arbuscular mycorrhizal fungi (AMF) associated with roots seed trees stands in a conserved and natural population mahogany (Swietenia macrophylla), based on rDNA sequences; (ii) to evaluate dual colonization by AMF dark septate (DSF), showing types fungal patterns dry season. Area Tropical rainforest Ejido Laguna Om, Quintana Roo, Mexico. Material methods: We evaluated DSF secondary root segments ten adult mahogany. analysed one composite sample...
Four Lepidoptera species that feed on leaves of M. schiedeana were recorded for the first time in tropical montane cloud forest at Veracruz, Mexico. Adult and immature stages are illustrated, including months occurrence behavioural traits larvae Janospyge jonas.
