Biodiversidad y cambio climático: diversidad de insectos en cuatro ecotipos de papa
(Universidad Nacional de San Antonio Abad del Cusco - UNSAAC, 2020-10-06) Yábar Landa, Erick; Velarde Durán, Edilberto; Del Castillo Espinoza, María Mercedes; Espinoza Becerra, Eliseo; Pando Callo, Edgar; Ardiles Jara, Alexander; Serrano Del Carpio, Judith Vita; Pacheco Del Castillo, Miguel Ángel; Palomino Flores, Ladislao; Velarde Peña, Arturo
El objetivo de este proyecto fue estudiar la interacción entre insectos y cuatro ecotipos de papa. El trabajo se realizó en la Estación Experimental Andenes del Instituto Nacional de Innovación Agraria (Anta, Cusco: 13°28’LatS, 72°13’LongW). Se evaluaron 4 ecotipos de papa: 513204, 511220, 511712 y 511318, los cuatro con tricomas glandulares. Se realizaron dos evaluaciones registrando el número de insectos en cinco plantas por ecotipo. Los resultados mostraron diferencias estadísticamente significativas para ecotipos, especies de insectos y la interacción ecotipos por especies de insectos. Hay una notoria asociación entre los ecotipos estudiados y algunos insectos, tanto plagas como benéficos. Tanto la existencia de numerosas variedades de papa como de los insectos asociados a ellas puede representar un factor importante para resistir los efectos del cambio climático.

The global decline in invertebrate diversity requires urgent conservation interventions. However, identifying priority conservation areas for invertebrates remains a significant challenge. We hypothesized that aligning the conservation of invertebrate biodiversity with climate change mitigation ofer offers a solution. As both soil carbon storage and invertebrate biodiversity are positively influenced by plant diversity and productivity, a positive correlation can also be expected between SOC and invertebrate biodiversity. Drawing on >10,000 invertebrate observations organized into functional groups, and site-specific soil organic Carbon (SOC) measurements from Patagonia, the Peruvian Andes, and montane tropical rainforest, we examined the role of climate, soil, topographical position and land use for prediction of invertebrate biodiversity. We found that taxonomic and functional invertebrate diversity and abundance closely correlate with SOC stocks within ecosystems. Topographical position of sites, which was partly associated with SOC, was also important, whereas land use was of subordinate importance. We conclude that recent advances in predicting and mapping SOC can guide the identification of habitats within landscapes with high biodiversity and conservation value for invertebrates. Our findings stress the importance of linking global climate change mitigation initiatives that aim to preserve and restore SOC to efforts aimed at improving the conservation of invertebrates and the ecosystem services they provide, for the realization of mutual climate and biodiversity benefits.
