プロジェクトデータ

Biodiversity patterns are influenced by environmental gradients associated with climatic and vegetational changes. In combination with physiographic barriers such as rivers and mountains, these environmental changes promote taxonomic differentiation and affect species distribution and often define transition zones between biogeographical units. The conservation of these transitional areas is a priority, as they may facilitate adaptation to climate and anthropogenic changes. The project proposed to study how species richness, distribution, abundance, and body size of insects vary along longitudinal and altitudinal gradients in the transition between the subantarctic forests and Patagonian steppes in northwestern Patagonia (Argentina). This is a region with one of the most pronounced environmental changes in the world, where precipitation varies from 500 mm to 3,000 mm over just 100 km. The influence of climate, topography, and resource availability on biodiversity patterns were analyzed. Although insects represent the largest share of global biodiversity, most studies on spatial diversity patterns have focused on birds and mammals. Furthermore, biodiversity analyses in insects have been scarce in the Southern Hemisphere. Beetles and ants are ideal groups for study due to their environmental sensitivity and key ecological roles in ecosystems. However, knowledge about insect fauna in this region remains insufficient for designing effective conservation strategies. The present study 1) provided data of the taxonomic and functional diversity of beetles and ants in the transition zone between forest and steppe, documenting species richness, distribution, abundance, and body size at local and regional scales; 2) applied geospatial tools (GPS and GIS) to map species distributions and correlate them with biological attributes. 3) Analyzed altitudinal and latitudinal variation in biodiversity and ecological traits of species. 4) Evaluated ecological hypotheses regarding the climatic, vegetational and soil factors influencing biodiversity along these gradients.

収集方法

Epigaeic beetles were collected using a total of 450 plastic pitfall traps (9 cm in diameter, 12 cm in depth), arranged in 50 grid plots (100 m² each), with nine traps per plot. These plots were spaced approximately 15 km apart along five longitudinal (east-west) transects, which were established across the forest-steppe biogeographic transition zone. The traps were filled with 40% diluted propylene glycol and a drop of soap. They became operative immediately upon installation and remained open for seven days during three sampling periods in the southern spring and summer seasons (November 2004, and January, March 2005–2006). Data on temperature at ground level, vegetation cover, plant species richness and soil conditions were also collected to provide an environmental characterization of each sampling plot, as detailed explained in Ruggiero et al. (2009).

Method step description:

1. The geographical location of each sampling plot was recorded in the field using a global positioning system (GPS). The dataset includes the decimal coordinates of each data point, referenced to the WGS84 datum. To associate the decimal coordinates of the sampling plots with political and administrative divisions at the sub-national level (provinces, departments, and municipalities or localities) within the study area, we used version 1.0 of the GADM database of global administrative boundaries, downloaded in March 2009. Beetle sampling was conducted at each plot at three key points during the plant growing season: the beginning (November 2004), middle (January 2005, 2006), and end (March 2005, 2006), ensuring coverage of the main period of beetle activity. To estimate beetle abundance at each of the 50 plots, we recorded the number of individuals captured per pitfall trap at each site and sampling event. The occurrence dataset includes the scientific names from our original database, verified against global biodiversity data sources using the Global Names Verifier (https://verifier.globalnames.org/), ensuring taxonomic accuracy. A detailed description of methods used to measure environmental variables at each sampling plot is given in Ruggiero et al. (2009).
