A list of 214species of trees and shrubs in 148 genera of 61 families is presented. Of these, the five most diverse represent 32% of the totaland Fabaceae, Euphorbiaceae and Pinaceae stand out. The number of species added to the previous work are 95 and 51 that nolonger exist were eliminated. Sheets with photographs of some representative species are presented. Of the total species, 156are trees and 58 are shrubs, so far, the largest number of tree species recorded in the entire University Network. Regarding theorigin of the trees and shrubs, 133 are native to Mexico and the rest are introduced. Of the 133 native taxa, 97 are trees, whichalso represents the largest number of native tree species on the Network. The contribution of the Didactic Botanical Garden ofthe Institute of Botany stands out for hosting a considerable number of these native species and contributing to teaching as avaluable teaching tool.

The diversity of forestspecies was characterized by calculating diversity indices. The structure of the forest species was described through the distributionof individuals by diameter class with a width of 10 cm and by height class with a width of 5 m. The surveys show that the studyarea has a partial specific richness of 40 species divided into 38 genera and 23 families. The Fabaceae family was the mostrepresentative with 11 species, and the most abundant species was Prosopis juliflora. Natural and human disturbances influence thediametrical and vertical structure. The structural analysis showed that, despite the existence of a reasonable number of species, inmost cases they are trees in minimal quantities, small and sporadically distributed.

Memory can be classified in several ways, one of them according to thepermanence of the information, considers a short- and long-term memory, mainly determined by the initial process of memoryformation. This process involves four fundamental stages: encoding, consolidation, store and retrieval, involving modification ofthe synaptic strength between neurons of an engram, with participation of specific neurotransmitters and receptors, giving rise toLong-Term Potentiation (LTP); the interaction of various brain areas is also required, mainly hippocampus and cerebral cortex.Memory storage is the result of dynamic processes between engrams, which represent a permanent but fragmented storage ofmemories, while memory retrieval involves an interaction between a stimulus and a previously stored engram set, being largelydependent on the repetition of the original engram connectivity pattern. Memory can be affected by toxic environments that altercommunication between neurons and/or brain structures, leading to memory loss. The most common pathologies where memory isaffected are Alzheimer’s disease, Parkinson’s disease and Lewy body dementia.","PeriodicalId":447849,"journal":{"name":"e-CUCBA","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134354678","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}

The waterresource of the Tecocomulco wetland is compromised by social and ecological uses and the real loss of the storage volume of thelagoon due to deforestation, causing an increase in soil erosion in the upper part of the basin, causing flooding, low yields inagricultural and livestock production, degradation of plant cover and loss of biodiversity. The objective was estimating the level oferosion in the Tecocomulco wetland, to justify the criteria to categorize it as a priority area for restoration and conservation. Theevaluation of the degree of hydric erosion was carried out based on the methodology proposed by Figueroa (1991), which uses theUniversal Soil Loss Equation (USLE), to estimate and predict average annual soil losses. To obtain statistics by erosion rangeaccording to the FAO (1984), the resulting map was classified into three ranges and subsequently statistical zoning was carried outto obtain the values.
