“…Species richness and Shannon index were significantly higher in the forest than in the other sites (K-W, H = 28.3; P < 0.00001; n = 48; K-W, H = 32.4; P < 0.00001; n = 48, respectively). These results agree with other studies in Colombia [51][52][53][54][55][56][57][58][59]. In contrast, Pielou's index (P) did not show any significant differences between areas with several post clearcutting ages (K-W, H = 6.35; P = 0.09; n = 48), but it was higher and less variable in the forest than the other sites (Table 3).…”

“…In Colombia, studies have investigated the macrofauna composition of Andean forests, exotic tree species plantations, and agricultural lands, revealing a higher soil macrofauna diversity in Andean forests compared to both conifer plantations and agricultural areas [51][52][53][54][55][56][57][58][59]. However, there are no studies investigating macrofauna succession processes nor the relationships between macrofauna and physico-chemical variables in areas after clearcutting of P. patula.…”

Soil macrofauna in areas with different ages after Pinus patula clearcutting

In Andean high montane areas, the establishment of exotic tree forests changes the soil dynamics and its biodiversity. Soil macrofauna act as indicators of ecosystem successional processes, and may have an important role in ecological restoration processes after clear cutting exotic tree plantations. The aim of the present study was to understand how soil macrofaunal assemblies change in areas with different ages post clear cutting of Pinus patula, and to identify the soil physico-chemical variables that better explain these variations. The macrofauna in a high montane forest was evaluated along with that of three areas with different ages post clearcutting: 0, 2.5, and 5 years after clearcutting (Yac). The effect of soil physico chemical variables on macrofauna abundance was also evaluated. Macrofauna composition changed after clearcutting. Macrofauna abundance, richness, and diversity were lower in the 0 Yac area than in the other areas. Moreover, the macrofuna similarity to the reference forest did not increase with the years after clearcutting. This is due to the changes in soil characteristics, triggered by clearcutting. Slope, temperature, bulk density, real density, loam, pH, P, Na and K were the soil variales with a positive effect on the macrofauna abundance. These physico-chemical variables should be considered when designing restoration plans for Andean forest ecosystems. Moreover, Diplopoda, Coleoptera and Chilopoda might be useful to monitor and evaluate restoration processes after Pinus spp. clearcutting, because of their high abundance, diversity and relationship with environmental conditions.

“…The meadow in Krasne was found to contain a similarly low level of biomass of 77.72 ± 15.30 g · m -2 ( Table 3). According to other studies, the arable land is characterised by lower density and biomass of Lumbricidae compared to the habitats not exposed to direct interference [Smith et al 2008, Feijoo et al 2011, Felten, Emmerling 2011]. This tendency has not been confirmed in the study conducted in Krasne.…”

Community Structure of Lumbricidae in Permanent Grassland and Arable Land

et al. 2019

Lumbricidae play a key role in the soil environment as "the ecosystem engineers". They participate in all the categories of services pro vided by ecosystems. In agricultural areas, the conventional intensive farming practices have led to a significant decline in the biological diversity of soils including earthworms. In this study, we attempted to characterize the community structure of earthworms in permanent grassland and arable land of the Didactic & Experimental Station of Rzeszów University in Krasne near Rzeszów. Similar densities of earthworms were observed in the grassland and in the arable land (101.01 ± 18.03 ind. · m -2 and 82.12 ± 18.26 ind. · m -2 , respectively) (p > 0.05) as well as a similar biomass of Lumbricidae (77.72 ± 15.30 g · m -2 and 54.34 ± 11.72 g · m -2 ) (p > 0.05). In the research, 7 species of earthworms were found in the permanent grassland and 6 representatives of Lumbricidae were identified in the arable land. The identified earthworms represented all three main morpho-ecological groups. The density and biomass of epi-endogeic earthworm L. rubellus and the anecic species of L. terrestris were shown to be higher (p < 0.05) in the grassland as compared to the arable land. In order to protect Lumbricidae and to sustain the beneficial role of earthworms in an ecosystem, it is necessary to monitor the negative changes in populations of earthworm species attributed to various farming practices.

“…Otro aspecto crucial de abordar sería el de la deslocalización del empleo (fuentes de ocupación próximas a los hogares), estudio (proponer modelos de educación virtual) y producción de alimentos no especializada en dos productos, sino diversificada y situada en la periferia de la ciudad.Servicios ecosistémicos de provisiónLos procesos de transformación de coberturas y usos del terreno (bosque a monocultivos y pastizales), se relacionan con la oferta de SE al homogenizarse las condiciones ambientales. La transición de cultivadores a criadores incrementó el impacto ambiental en los nuevos usos establecidos, se desnudaron los suelos al reducir la capacidad de reciclaje de biomasa vegetal(Díaz, 2009) por la ausencia de árboles, se disminuyó la captura del carbono, se compactaron los suelos con graves efectos en la capacidad de albergar la biodiversidad(Feijoo et al, 2007;Feijoo, Carvajal, Zúñiga, Quintero & Fragoso, 2011).Considerando que la agricultura tradicional se ha visto reducida tanto en superficie como en producción debido a la expansión de los sistemas agroindustriales, el aumento en la producción de alimentos supone una disminución de la capacidad de los ecosistemas para ofrecer servicios de regulación del suelo(Lavelle, 2013). El cambio en los usos del terreno y la consecuente degradación de los ecosistemas y la biodiversidad afectan la oferta de SE, por consiguiente, la hipótesis formulada en este artículo se corroboró al precisar que la demanda de los servicios de provisión está aumentando a medida que crece la población, se modifican las coberturas y usos del terreno, y se incrementa la urbanización en Armenia.…”

El crecimiento urbano produce impacto en las coberturas boscosas, los territorios agrícolas y la provisión de servicios ecosistémicos. Se propuso analizar en Armenia las relaciones entre el crecimiento urbano, el componente rural y urbano de la población y la oferta de servicios ecosistémicos de provisión (café, plátano y carne). El trabajo se orientó hacia: (i) el análisis de la tendencia demográfica 1938-2005, (ii) la dinámica de expansión entre cabecera municipal y el territorio agrícola (1998–2015) y, (iii) la oferta de servicios ecosistémicos que aportan a la seguridad alimentaria. En 1998 el municipio experimentó una fragmentación territorial que afectó la oferta de servicios. En el 2015, se evidenció la homogenización territorial, en la zona alta se concentraron los procesos de urbanización en los pastos adyacentes al perímetro urbano, mientras la zona media y baja dominan los cultivos de café y plátano. La dinámica del crecimiento urbano en Armenia generó presión sobre los bosques que disminuyeron las coberturas agrícolas y, en consecuencia, sobre los servicios ecosistémicos que ofrecen estas coberturas en el territorio, lo que afectó la posibilidad de alcanzar un desarrollo rural productivo y sustentable.
