“…As energy-related variables, we estimated temperature, water availability, and net primary productivity (NPP). Mean summer temperature data was derived from WorldClim V.II 57 with a spatial resolution of 30 s (~ 1 km 2 cell grid) 57 , an improved version of WorldClim database 58 , widely used in mountains 12 , 59 . This original WorldClim database used data of climatic stations and altitude to develop interpolated climate surfaces 58 , the new version includes new variables in the interpolation process, coast distance, and three satellite‐derived covariates: maximum and minimum land surface temperature and cloud cover, obtained with the MODIS satellite platform 57 .…”

Spatial patterns of species richness have been found to be positively associated, a phenom called cross-taxon congruence. This may be explained by a common response to environment or by ecological interactions between taxa. Spatial changes in species richness are related to energy and environmental heterogeneity but their roles in cross-taxon congruence remain poorly explored. Elevational gradients provide a great opportunity to shed light on the underlying drivers of species richness patterns. We study the joint influence of environment and biotic interactions in shaping the cross-taxon congruence of plants and orthopterans species richness, along three elevational gradients in Sierras Grandes, central Argentina. Elevational patterns of species richness of orthopterans and plants were congruent, being temperature the best single predictor of both patterns supporting the energy-related hypotheses. Using a structural equation model, we found that temperature explained plant richness directly and orthopteran richness indirectly via orthopteran abundance. Cross-taxon congruence is likely due to a common response of both taxa to temperature although via different theoretical mechanisms, possibly, range limitations for plants and foraging activity for orthopterans. We disentangled the role of temperature in determining the cross-taxon congruence of plants and orthopterans by showing that a common response to the environment may mask different mechanisms driving the diversity of different taxonomic groups.

Potential biodiversity maps (PBMs) allow the identification of areas with different potential for conservation, to support political decisions about the management and protection of biodiversity. As these maps are seldom constructed for inconspicuous species, we proposed to develop PBMs for species belonging to the Geadephaga (Coleoptera), which is a group of beetles that contributes as predators for pest suppression and other ecosystem services in forest ecosystems. Given that human activities are reducing forest integrity, we consider that it is crucial to recognize how diversity patterns of Geadephaga are related to degraded forests. We developed these maps for the Geadephaga associated with subantarctic forests considering diversity measures of species richness, specificity, and rarity to establish spatial relationships between each diversity measure and different levels of forest integrity, and to identify potential hotspots and suggest conservation priorities. Results showed a latitudinal pattern of decrease in scores on richness and specificity from north to south, but a patchy pattern of species rarity across the region. Outcomes also show that areas with high scores of diversity measures are overlapped with degraded forest, and that hotspots have a low spatial overlap between them. In this work, we provide for the first time regional PBMs at a relatively high spatial resolution of three different diversity measures for Geadephaga that inhabit subantarctic forest. These maps constitute tools that allow not only to recognize potential diversity patterns of these insects, but also to offer valuable information to be used in conservation decision‐making.

Late Pleistocene outcrops exposed in Buenos Aires province, Argentina, represent one of the most informative sources for paleoecological studies on South American fauna and flora. Several proxies have been used for studying Pleistocene environmental conditions in the Pampas, but only a few were based on paleoentomological data. The aims of this study are to present the first record of three species of darkling beetles from the late Pleistocene of Buenos Aires province and to provide new paleoenvironmental information. The sediments containing fossil insects correspond to the Guerrero Member of the Luján Formation and were dated between 12,100 ± 100 14C BP and 13,400 ± 200 14C BP. Specimens of Nyctelia picipes (Billberg), Epipedonota cristallisata Waterhouse and Scotobius pilularius Germar were identified. To provide information about past climate, the particular climate requirements of these species were analyzed by using the Mutual Climatic Range method. This association could indicate the first pulse of post-glacial climate recovery and the replacement by the insect fauna currently inhabiting the area. This study is one of the first approaches to the Quaternary paleoentomology of Argentina, and highlights the potential of paleoentomological information, when evaluated in combination with previous knowledge on global climate conditions after the last glacial maximum.
