“…Nonetheless, some critical ecosystems, including arid shrublands and deserts, are underrepresented by PES schemes (Wunder 2007 ). These ecosystems contain unique climate-sensitive insect communities (Tirado et al 2018 ) that could benefit indirectly from such market-based incentives.…”

Emerging evidence suggests that insect populations may be declining at local and global scales, threatening the sustainability of the ecosystem services that insects provide. Insect declines are of particular concern in the Neotropics, which holds several of the world’s hotspots of insect endemism and diversity. Conservation policies are one way to prevent and mitigate insect declines, yet these policies are usually biased toward vertebrate species. Here, we outline some key policy instruments for biodiversity conservation in the Neotropics and discuss their potential contribution and shortcomings for insect biodiversity conservation. These include species-specific action policies, protected areas and Indigenous and Community Conserved Areas (ICCAs), sectoral policies, biodiversity offsetting, market-based mechanisms, and the international policy instruments that underpin these efforts. We highlight that although these policies can potentially benefit insect biodiversity indirectly, there are avenues in which we could better incorporate the specific needs of insects into policy to mitigate the declines mentioned above. We propose several areas of improvement. Firstly, evaluating the extinction risk of more Neotropical insects to better target at-risk species with species-specific policies and conserve their habitats within area-based interventions. Secondly, alternative pest control methods and enhanced monitoring of insects in a range of land-based production sectors. Thirdly, incorporating measurable and achievable insect conservation targets into international policies and conventions. Finally, we emphasise the important roles of community engagement and enhanced public awareness in achieving these improvements to insect conservation policies.

“…They play different ecological roles, such as increasing the primary and secondary production of their ecosystems (Ayal, 2007) either due to their ability to pollinate or their ability to dynamize the flow of energy or the nutrient cycle, while at the same time being abundant, high-quality trophic resources (Vidal, Pizarro-Araya, Jerez, & Ortiz, 2011). During the dry season, they function as important macrodecomposers and are significant trophic resources both for invertebrates (Pizarro-Araya, 2010;Cruz-Jofré & Vilina, 2014) and vertebrates (Vidal et al, 2011;Tirado, Trujillo, Pizarro-Araya, Alfaro, González, & Carretero, 2018).…”

We provide the first inventory of terrestrial arthropods from La Chimba National Reserve (Antofagasta Region, Chile), a protected area whose purpose is to preserve the biota of the Coastal desert of Tocopilla embedded in the larger transitional coastal desert. The study was conducted during spring of 2019. A total of 2,852 specimens were recorded, distributed across 188 species. Among the collected specimens, 5 new species were identified: two species of scorpions, Brachistosternus chimba Ojanguren-Affilastro, Alfaro & Pizarro-Araya, 2021 and Rumikiru sp. nov. (Scorpiones: Bothriuridae); a solpugid (Solifugae: Ammotrechidae); a spider (Araneae: Filistatidae), and a centipede (Scutigeromorpha: Scutigeridae). The richness estimations showed large values for most arthropod groups, which is evidence of an incomplete inventory of species richness. The article also discusses the current threats faced by these communities of endemic arthropods and suggests immediate actions to preserve these groups in extremely fragile semiarid ecosystems.

“…Finally, understanding how a species' activity relates to environmental conditions (i.e. temperature and other weather variables) can help inform us when monitoring should take place and how climate change might affect a species' activity (Tirado et al 2018). How a species reacts to local weather conditions is especially important to understand when studying ectotherms because the ability of ectotherms to be active is strongly influenced by temperature and other weather conditions in their environment (Angilletta 2009).…”

The number and type of threats that a species is exposed to is often influenced by their activity patterns. For ectotherms, environmental conditions are likely to strongly influence activity, given that external heat is needed to reach body temperatures that promote physiological functions, including locomotion. As a result, one might expect ectotherms to avoid cold environments, such as the alpine zone, known for large temperature variations and prolonged winters. However, many endemic lizards, including diurnal skinks (Oligosoma spp.), inhabit the alpine zone across Aotearoa, New Zealand. We used trail cameras to monitor the surface activity of skinks (likely to be predominantly McCann's skinks, Oligosoma maccanni) in the alpine zone of the southern South Island (c. 44°S; 1150 to 1600 m a.s.l.) from spring until autumn. We asked: (1) under which environmental conditions do skinks emerge? (2) which temperatures and other weather variables promote the highest levels of surface activity? and ( 3) what sort and duration of activity are typical? We observed more skink activity when temperatures at basking locations were warm, with 95% of skink observations occurring when temperatures recorded at copper models were between 13.2 and 43.2°C; these patterns follow trends observed in McCann's skinks at lower elevation and in species of alpine skinks in Australia. Furthermore, skinks were most active when conditions were dry and sunny, with observations in mid-summer peaking in the late afternoon. When visible, skinks were very mobile, only remaining in the same position for 1-3 min. Our study increases understanding of a generalist skink in an alpine environment. During summer, activity of skinks is highly dependent on warm sunny conditions, and our study highlights trail cameras as an effective tool for monitoring behaviour (including potential predator exposure) in this remote environment.
