“…Piscidia piscipula (L.) Sarg. (jabín) es una especie arbórea de importancia ecológica por su dominancia y abundancia en las selvas medianas subperennifolias del estado de Campeche (Echeverría et al, 2014;Zamora-Crescencio et al, 2018). Asimismo, el jabín es localmente considerado como árbol multipropósito y empleado en los sistemas silvopastoriles y el manejo tradicional (Zamora-Crescencio et al, 2009).…”

Las ecuaciones alométricas específicas son una herramienta clave para estimar la biomasa aérea total y por componente y el carbono de los bosques tropicales. El objetivo de este estudio fue ajustar modelos alométricos para estimar la biomasa aérea y por componente estructural de árboles de Piscidia piscipula en una selva mediana subperennifolia de Escárcega, Campeche, México. A través de un muestreo destructivo de 17 individuos de distintas categorías diamétricas (5 cm a 55 cm) se obtuvieron muestras de fuste, ramas y ramillas con hojas para determinar su peso seco. Se ajustaron dos sistemas de ecuaciones no lineales utilizando al diámetro normal (Dn) y la altura total (AT) como variables predictoras con el método generalizado de momentos. La propiedad de aditividad fue asegurada al definir a la biomasa aérea total como la suma de las estimaciones de la biomasa de cada componente estructural del árbol. La concentración de carbono expresado como porcentaje de la biomasa fue determinada en cada componente. El sistema de ecuaciones alométricas basado en el modelo y=e [-b0+b1ln (Dn)+b2ln (AT)] mostró los mejores estadísticos de ajuste y explicó más de 89% de la variabilidad de la biomasa de los componentes y total del árbol. En P. piscipula, la mayor proporción de biomasa se concentró principalmente en el fuste (60.4%), luego en las ramas (36.8%) y finalmente las ramillas con hojas (2.7%). La concentración de carbono promedio fue de 49.9% ± 0.48%. Las ecuaciones alométricas generadas proporcionan estimaciones confiables de biomasa que garantizan la aditividad entre los componentes estructurales de P. piscipula.

“…Se comparó la riqueza florística de San Juan Colorado con la de otras regiones; principalmente con trabajos realizados en la región Costa, entre los que destaca la flora de la costa de Oaxaca en la región de Zimatlán (71339 km 2 ) y la flora de Bahías de Huatulco (5098 km 2 ); dicha comparación evidenció que, San Juan Colorado tiene un alto índice de riqueza a pesar de contar con sólo 0.1% de la superficie con respecto a la región de Zimatlán y 1.7% en relación a la de Bahías de (Zamora-Crescencio et al, 2012).…”

The plant diversity has been and is the main theme of very diverse and different projects due to the need to know and use plant resources in a sustainable way; several factors have been identified that threaten this diversity, such as: the destruction of habitats, environmental pollution, overexploitation of resources, the introduction of exotic species and climate change. Although many and very diverse studies have been carried out on the diversity and vegetation of the country, the biodiversity of many regions and of various groups of plants is still unknown; as are the phanerogams of Oaxaca, which constitute 89.4% of the 255 families reported for the country (Espejo-Serna et al., 2004;Villaseñor, 2004). The 1841 genera represent 69% of the 2677 ocurrung in Mexico and the 8228 species in the state represent 37.3% of the 22397 in the country (Villaseñor, 2004), which shows the great diversity present in the state of Oaxaca. García-Mendoza ( 2004) reported for the state 223 families, 1712 genera and 7804 species of phanerogams, being the angiosperms, the best represented with 217 families, 1700 genera and 7752 species. In an update of these data, García-Mendoza & Meave (2011) reported 228 families, 1841 genera and 8228 species, of which 667 are endemic to Oaxaca. In Villaseñor (2016), 226 families, 1783 genera and 9411 species were reported. The importance of documenting the plant richness in many places is, therefore, cannot be postponed, if we also consider the accelerated destruction of ecosystems and the incomplete knowledge of their components. That is why the objective of this work was to develop an inventory of the phanerogamic flora of the municipality of San Juan Colorado, district of Jamiltepec, located in the south-western part of the state of Oaxaca.Between 2014 and 2017, several botanical collection trips were made to various locations in the municipality, giving preference to the best-preserved areas.Likewise, the specimens deposited in the ENCB, MEXU and UAMIZ herbaria were reviewed to detect the material from the study area. To identify or collate the determination of the specimens, specialized literature was used in each of the study groups. The supporting material collected during the study was deposited in the Herbario Metropolitano (UAMIZ) and duplicates were distributed to institutions in the pedicelo, sobrepuesto, con 2 lóculos, polen con dos alas prominentes como sacos en cada grano; megastrobilos (conillos) en grupos pequeños en el ápice de las ramas, escamas ovulíferas numerosas, leñosas, abiertas en corto período para recibir el polen y cerradas inmediatamente después de la polinización; óvulos 2 por escama. Fruto un cono, simétrico u oblicuo, con numerosas escamas abiertas o cerradas, el umbo dorsal o terminal a la escama variable en grosor, con una cúspide que termina en una espina aguda o gancho, persistente o decidua; semillas similares a nueces, aladas o sin ala, testa suave o endurecida.Género con cerca de 94 especies, para México se han citado 47 especies,

The relationship between arbuscular mycorrhizal fungi (AMF) and secondary vegetation (SV) species at early phenological stages is critical for the successful establishment of these plants on disturbance sites in temperate forests. The main objective of this research is to evaluate the effect of AMF colonization on the early phenological stages (germination and early growth) of three shrub species present in the SV of a temperate forest in central Mexico. We collected soil from different sites in the Abies religiosa forest in central Mexico. We collected seeds of Acaena elongata, Ageratina glabrata, and Solanum pubigerum. We used a controlled experimental design with pasteurized soil (-AMF treatments) and unpasteurized soil (+ AMF treatments). We monitored germination percentage, growth (shoot and root weight and total biomass), AMF root colonization, and the mycorrhizal response index (MRI) for each plant species. All three species tested benefited by AMF, showing higher germination rates. Shoot and root weight and total biomass were significantly higher in the + AMF treatment. Solanum pubigerum showed greater stem length and Ageratina glabrata showed greater root development due to AMF. Ageratina glabrata and Acaena elongata were the most responsive to AMF as indicated by MRI. This research underscores the critical role of AMF in the early phenological stages of SV and highlights the potential ecological benefits of AMF in supporting plant germination and plant growth. These results suggest that AMF enhance germination and early growth of secondary vegetation species, which can be considered in management plans for forest ecosystems.
