Montoya Rojas, Grace Andreas | 2020

This research shows that the correlations of the Port-Waterfront Cities and their development throughout history have led to conceptual evolution to strengthen and implement: sustainable cities. The main objective of this research was to perform a detailed analysis of the relationships between the Biogeographical Systems and the dynamics of the Port-Waterfront Cities, to make an integrated approach between human and natural relations in these urbanized coastal-marine regions. Analytical tools associated with the General Theory of Systems and critical thinking are employed. The reliable conceptual documentation is analyzed for achieving the preset objectives of the present research. Subsequently, a historical analysis of the Port-Waterfront Cities was carried out, and a conceptual map was prepared by integrating conceptual information and the proposed biogeographic systems such as the atmospheric, the hydrospheric, the geospheric, the biospheric and the anthropospheric. Furthermore, a Sankey Diagram was developed to understand interactions between the biogeographic systems and their dynamic flows entering the marine-coastal urban environment. In the present research, the city of “Cartagena de Indias” and its surroundings in Colombia have been considered. Finally, sustainability guidelines developed through a multi-criterion analysis were established as a contribution to urban planning management and territorial ordering tools in marine-coastal environments.

Resilience of Soil Properties to Land-Use Change in a Tropical Dry Forest Ecosystem

Ayala Orozco, Bárbara | 2018

Land-use change in tropical dry forests can dramatically alter soil properties, but little is known about their resilience. We assessed soil resilience by examining resistance to, as well as recovery from, pasture use by smallholder farmers in western Mexico. We measured 25 soil and vegetation properties and compared old-growth forest (OGF) sites and pastures to evaluate resistance to pasture use. We assessed whether those properties recovered to OGF reference values after pasture abandonment by analyzing the trajectories of properties along a chronosequence of secondary vegetation. Finally, we assessed whether recovery of soil properties could be inferred from the recovery of vegetation properties. Nine out of 25 properties differed significantly between the OGF sites and pastures. From these nine nonresistant properties, six (i.e., penetration resistance, soil C concentration, soil C/N, basal area, individual density, rarefied species richness of woody vegetation) showed recovery as a significant positive relationship with forest age. In contrast, surface litter C, litter C/N, and soil available P showed no resistance and no recovery within the successional period examined (up to 35 y). The best vegetation indicator for the recovery of some soil properties was woody species richness. This may suggest that functional differences of colonizing plants matter for recovery after pasture use. Our findings indicate that soil was overall resilient to pasture use, but some properties did not recover synchronously with vegetation properties during succession. Thus, more attention should be paid to soil function, because full ecosystem recovery is often inferred from the recovery of vegetation properties.

Stomatal behavior in fruits and leaves of the purple passion fruit (Passiflora edulis Sims) and fruits and cladodes of the yellow pitaya [Hylocereus megalanthus (K. Schum. ex Vaupel) Ralf Bauer]

Las plantas C3 y CAM reaccionan fotosintéticamente diferentes, sin embargo, ambas pueden crecer en la misma zona agroecológica en los trópicos. Por esta razón se evaluó el comportamiento de estomas en frutos y hojas de gulupa y en frutos y cladodios de pitahaya amarilla bajo condiciones naturales en los municipios de Granada y Fusagasugá, departamento de Cundinamarca (Colombia). Se hicieron improntas sobre la superficie de las hojas, frutos y cladodios. Se realizaron tres lecturas, cada una duró 72 horas, haciendo impresiones cada 3 horas sobre tres muestras diferentes para luego observarlas en microscopio, haciendo un conteo de estomas abiertos y cerrados en cada especie. En cada muestreo se obtuvieron datos de radiación solar, temperatura y humedad relativa (HR). En gulupa se encontró un comportamiento típico de una planta C3 tanto para las hojas como para los frutos, además de encontrar una correlación positiva entre la apertura estomática y la radiación y temperatura, así como una correlación negativa entre la apertura estomática y la HR. En pitahaya se encontró un comportamiento típico de una planta CAM, observando una correlación negativa entre la apertura estomática y la radiación y temperatura, así como una correlación positiva entre apertura estomática y HR. La radiación, la temperatura y la HR afectaron la apertura estomático en frutos y cladodios. Las densidades estomáticas contrastaron altamente entre las especies y los órganos de la planta. En gulupa fueron encontrados 106,53 estomas/mm2 en la superficie de las hojas, pero solo 12,64 estomas/mm2 en la del fruto; mientras que en pitahaya fueron encontrados 11,28 y 1,43 estomas/mm2 en cladodios y frutos, respectivamente.
