“…Regarding seasonality, in central Chile the flowering and fruiting season of many species of Cactaceae occurs in the spring and summer months, respectively [ 127 – 129 ] and many aquatic birds begin laying their eggs during early spring [ 88 ]. Although there is scarce record of charred Cactaceae seeds and anatid eggshells in the lower portion of L4b, these evidence are sufficient to suggest that the activities carried out at TT-3 occurred during the dry season.…”

We present the results of the excavations and analyses of the diverse and exceptional archaeological assemblage of Taguatagua 3, a new late Pleistocene site located in the ancient Tagua Tagua lake in Central Chile (34°S). The anthropogenic context is constrained in a coherently dated stratigraphic deposit which adds new information about the mobility, subsistence strategies, and settlement of the early hunter-gatherers of southern South America. The age model constructed, as well as radiocarbon dates obtained directly from a combustion structure, indicate that the human occupation occurred over a brief time span around 12,440–12,550 cal yr BP. Considering taphonomic, geoarchaeological, lithic, archaeobotanical, and zooarchaeological evidence, as well as the spatial distribution combined with ethnographic data, we interpret Taguatagua 3 as a logistic and temporary camp associated mainly with gomphothere hunting and butchering. Nevertheless, several other activities were carried out here as well, such as hide and/or bone preparation, small vertebrate and plant processing and consumption, and red ochre grinding. Botanical and eggshell remains suggest that the anthropic occupation occurred during the dry season. Considering the contemporaneous sites recorded in the basin, we conclude that the ancient Tagua Tagua lake was a key location along the region’s early hunter-gatherer mobility circuits. In this context, it acted as a recurrent hunting/scavenging place during the Late Pleistocene due to its abundant, diverse, and predictable resources.

“…For this analysis, only the hand‐netting data were used. We combined the networks in the sites at the level of regime category, resulting in three meta‐networks for each post‐fire year (i.e., core, perimeter, and unburnt); this was useful because of the small size of the hoverfly–plant networks at the site level (see also Librán‐Embid et al, 2021 ; Medel et al, 2022 , for similar applications). Consequently, our point of reference has been the regime category at the regional (island) level (Table 4 ).…”

Fire affects many critical ecological processes, including pollination, and effects of climate change on fire regimes may have profound consequences that are difficult to predict. Considerable work has examined effects of fire on pollinator diversity, but relatively few studies have examined these effects on interaction networks including those of pollinators other than bees. We examined the effects of a severe wildfire on hoverfly pollinators in a Mediterranean island system. Using data collected over 3 consecutive years at burnt and unburnt sites, we documented differences in species diversity, abundance, and functional traits, as well as hoverfly interactions with flowering plants. Hoverfly abundance and species richness peaked during the first post‐fire flowering season (year 1), which coincided with the presence of many opportunistic species. Also in year 1, hoverfly pollination networks were larger, less specialized, more nested, and less modular at burnt (vs. unburnt) sites; furthermore, these networks exhibited higher phylogenetic host‐plant diversity. These effects declined over the next 2 years, with burnt and unburnt sites converging in similarity to hoverfly communities and interaction networks. While data obtained over 3 years provide a clear timeline of initial post‐fire recovery, we emphasize the importance of longer‐term monitoring for understanding the responses of natural communities to wildfires, which are projected to become more frequent and more destructive in the future.

“…He further suggested that examining specimens collected during the austral fall and winter from northwest Argentina and Bolivia would be important for understanding distribution and movement (Ortiz-Crespo 1986). Since Darwin's mention of migration in 1839, many published accounts have mentioned Patagona migration or presence/absence of Patagona at certain times of the year in Chile with few additional details (e.g.,(Gould 1861, Barros 1952, Aguirre 2001, González-Gómez and Valdivia 2005, Estades et al 2008, Speziale and Lambertucci 2009, Velásquez-Noriega et al 2021, Medel et al 2022, Rueda-Uribe et al 2023). One publication stated that Patagona migrates 2,000 km(Rodríguez-Flores et al 2019), but no information about the migratory route or sources for distance traveled were provided.…”

Giant hummingbirds (Patagonaspp.) are extraordinarily large but nondescript hummingbirds whose taxonomy has been muddled for two centuries.Patagonasystematics were redefined in a study of migration, physiology, and genetics by Williamson et al. (2024), revealing two species with divergent genomes and seasonal range overlap: Southern Giant Hummingbird (P. gigas) and Northern Giant Hummingbird (P. chaski). However, the taxonomy and nomenclature of the genus need to be reconsidered in light of its newly-clarified biology and species limits. The species namegigas(Viellot 1824) and subspecies nameperuviana(Boucard 1893) were both described based on multiple syntypes. Here, we designate a lectotype for each name and we critically consider the identity and usage of each. The lectotype ofP. gigasappears to be a Southern Giant Hummingbird, albeit from unknown provenance, and the historic and ongoing usage of this name has been restricted to that entity. Theperuvianalectotype appears to be a Northern Giant Hummingbird, but usage of the name throughout history has involved misdiagnosis and misapplication to entities that comprise variable mixtures of the two giant hummingbird species. Redefiningperuvianato match Northern Giant Hummingbird would shift the entity to which this name has referred, sowing confusion due to its non-universal meaning. By contrast, the species namechaskiwas introduced concomitantly with the definitive discovery of the twoPatagonaspecies and their taxonomic limits, morphology, physiology, migration, genetics, and year-round distributions. The Principle of Priority (Art. 23) of the International Code of Zoological Nomenclature provides a mechanism to suppress problematic senior synonyms. We invoke Art. 23.9.3 and urge suppression ofperuvianaand adoption ofchaski, the only name that applies specifically and uniquely to Northern Giant Hummingbird. Lastly, we report misidentified specimens in major museum collections, and we provide comprehensive information on species identification and seasonal ranges for these cryptic species.
