Freshwater ecosystems are among those most affected by human activity. Constructing artificial reservoirs can change freshwater biodiversity, thereby impacting genetic diversity (GD), which is crucial to population‐level adaptation. The Maipo River basin, inhabited by the endemic silverside Basilichthys microlepidotus, is one of Chile's most impact...

Full-text available
In the last decades, pollinators have drastically declined as a consequence of anthropogenic activities that have local and global impacts. The food industry has been expanding intensive agriculture crops, many of them dependent on animal pollination, but simultaneously reducing native pollinator habitats. Chile is a good example of this situation....

Bees are a diverse group of insects that have tremendous importance as pollinators. In the last decades, there was a global decline in bee populations due to land‐use change, intensive agriculture, and climate change. Unfortunately, our knowledge of native bees' ecology is rather scarce, and such knowledge gaps are also a major threat to its conser...

1.- The presence of a dam disturbs river flow, which in turn directly affects the communities and evolutionary potential of riverine species. To detect the ecological effects of a dam on genetic diversity, genetic structure, and their progress in time, two riverine fishes living upstream and downstream of an irrigation reservoir were studied at two...
Article
Alchisme grossa is a treehopper species showing maternal care until at least the third nymphal instar. A secondary female treehopper has frequently been observed near a family (primary female guarding its egg clutch). Intraspecific brood parasitism, communal breeding or alloparental care may be suggested as possible mechanisms to explain secondary...

Durante los últimos años en Chile se ha detectado una masificación en el uso de anticonceptivos orales. Sin embargo, en Chile y al igual que en casi todos los países latinoamericanos prácticamente no se han investigado sus implicancias sobre la conducta humana. Específicamente, este estudio evaluó el impacto del uso de estos anticonceptivos sobre l...

Investment in soldier production in eusocial lineages involves a trade-off between maintenance costs and defense benefits. Termites are eusocial insects that live in colonies organized into three castes: primary reproductives, soldiers, and workers or pseudergates. Neotermes chilensis (Blanchard) (Isoptera: Kalotermitidae) is a one-piece nesting te...

Oral contraceptives, also known as birth control pills (PAs from now on), have been available on the world market for five decades. At present, the use of PA is massifier worldwide, being consum ed by more than 100 million women on the planet. In recent years, in Latin America has been detected a dramatic increase in the use of oral contra ceptives...

Nestmate recognition is a necessary capacity for the occurrence of discrimination between nestmate and non-nestmate individuals. In one-piece nesting termites, which nest and forage in a single piece of wood, nestmate recognition is poorly studied mainly because the probability of encountering exogenous individuals is low in comparison with separat...

Background In one-piece nesting termites, which nest and forage in a single piece of wood, soldier production increases during the swarming period, i.e. when the risk of invasion of their substrate and hence of their colony by dealates in search of a nesting substrate increases. In Neotermes chilensis, a one-piece nesting termite endemic to Chile,...

The pronotum is the most distinctive and representative structure in treehoppers. Although several functions have been proposed for this structure, its involvement in fitness has not been formally evaluated. Given the high degree of maternal investment exhibited by the subsocial membracid Alchisme grossa (Hoplophorionini), the pronotum has been sug...
Article
The present study reevaluates mating in Sphex latreillei (Lepeletier) based on the analysis of 69 filmed reproductive interactions from a population in central Chile. Behaviors recorded before, during, and after copulation were analyzed through Markov chains, identifying statistically significant behavioral transitions that are summarized in a mati...

Several studies have demonstrated the relationship between handgrip strength (HGS) and fighting ability in men, which is a relevant trait for intrasexual competition to increase the probability of obtaining a mate. However, few studies have determined a relationship between fighting ability and men’s self-perceived capacity to find, attract and ret...
Article
Inbreeding depression refers to a decrease in fitness components in the offspring of closely related sexual pairs. Given the disadvantages of inbreeding depression, it is of interest to study the mechanisms involved in its avoidance, particularly in social insects. In termites, colonies are founded by dispersing individuals. Two types of mechanisms...
Conference Paper
The implications of host-mediated differentiation for insect diversification, under an ecological scenario, have broadly been documented in insects. The study of this phenomenon requires the identification of the traits which enable them to become specialized in the use of a given resource. Numerous reports have addressed these issues in phytophago...

Treehoppers (Membracidae) exhibit different levels of sociality, from solitary to presocial. Although they are one of the best biological systems to study the evolution of maternal care in insects, information on the biology of species in this group is scarce. This work describes the biology and ecology of Alchisme grossa (Fairmaire) (Hemiptera: Me...

Host plants are used by herbivorous insects as feeding or nesting resources. In wood-boring insects, host plants features may impose selective forces leading to phenotypic differentiation on traits related to nest construction. Carpenter bees build their nests in dead stems or dry twigs of shrubs and trees; thus, mandibles are essential for the nes...
Article
Purpose – Adolescent aggressive behavior has generated concern about/increasing rates of youth violence in schools. It is important to perform new research using different methods and approximations to obtain a better understanding of this multifactorial phenomenon. A poorly studied area consists of the presence of seasonal differences in adolescen...

Article
Parasitoid fitness depends on the ability of females to locate a host. In some species of Ichneumonoidea, female parasitoids detect potential hosts through vibratory cues emanating from them or through vibrational sounding produced by antennal tapping on the substrate. In this study, we (1) describe host location behaviors in Grotea gayi Spinola (H...

This paper reports the results of a behavioral study carried out at Farellones, Metropolitan Region, Chile, using females of Protandrena evansi. Tolerant and intolerant behaviors were observed in an experimental arena where pairs of females from the same nest (intra-nest interaction) or from different nest (inter-nest interaction) were placed. Neit...
Article
The subfamily Xylocopinae has been recognized as the most basal lineage within the family Apidae, comprising four tribes; Allodapini, Ceratinini, Xylocopini and Manueliini. Relationships among the tribes are not well resolved with morphological data. In particular, Manueliini and Xylocopini have each been placed as the most basal lineage in separat...
Article
The recognition of conspecifics is a central issue to social behaviour. In eusocial hymenopterans, kin recognition has been clearly demonstrated. Manuelia postica is a largely solitary bee species in which larvae develop inside individual cells within a nest and remain isolated from conspecifics until the destruction of partitions by adults. Nestma...

The Xylocopinae contains four tribes with species which show a range of nesting habits, from solitary to social. The Manueliini is the sister group to all other Xylocopine tribes, with one genus, Manuelia, of three species found mainly in Chile. This is a solitary genus, whose biology is scarcely known for two species, M. gayatina and M. gayi, and...

In eusocial Hymenoptera, females are more tolerant towards nest-mate than towards non-nest-mate females. In solitary Hymenoptera, females are generally aggressive towards any conspecific female. Field observations of the nest biology of Manuelia postica suggested nest-mate recognition. Experiments were performed involving two live interacting femal...

... We note that not all species of Phyllostomidae are flower visitors but include the whole group for simplicity. Generally, these taxa provide pollination services to a large fraction of flowering wild plants and cultivated crops and comprise culturally iconic species and rarities of conservation importance (IPBES, 2019;Vieli et al., 2021). We begin by conducting a continental-scale assessment of the GBIF data for common forms of bias in the geographic, temporal and taxonomic dimensions. ...
... Although agricultural pollinators have been well studied, native pollinators remain largely unknown. With over 460 species of native bees in Chile, approximately 70% are endemic; researchers have only begun to understand the relationships between native plants and their pollinators [22][23][24] . Also, managed honeybees and bumblebees introduced to Chile for crop pollination are highly invasive and easily leave croplands to forage in neighbouring native ecosystems 25,26 , competing directly with native pollinators for the ever-diminishing resources in native grasslands and forests posing a threat to Chile's unique ecoregions 25,27 . ...
... Neutral genetic markers allow to investigate if gene flow and therefore functional connectivity is still present along river networks 24,25 , if there is local population decline 26 , or ongoing migration 27 despite fragmented habitat. This information is crucial to assess the importance of tributaries and the contribution of single populations to genetic diversity further up-or downstream 28,29 . ...
... For example, Taylor and Kent (2013) included an unknown species of Brugmansia among the hosts of Acizzia solanicola Kent & Taylor, 2010 (Hemiptera: Psyllidae). Similarly, Pinto et al. (2020) observed the presence of the leafhopper Alchisme grossa (Fairmaire, 1846) (Hemiptera: Membracidae) in B. suaveolens. In Brazil, Epilachna vigintioctopunctata (Fabricius, 1775) (Coleoptera: Coccinellidae) larvae were also found in B. suaveolens (Casari and Teixeira, 2015). ...
... Fisher's exact test Percentage of families parasitized with at least one mite larva on the female or its as cuticular chemical compounds in A. grossa (Torrico-Bazoberry et al. 2018), which may vary between host-plants since A. grossa has been shown to incorporate alkaloids from BS ). Thus, cuticular extracts have been observed mediating host searching behaviour in the mites Grandiella rugosita Summers and Schuster, 1979 (Sarcoptiformes: Canestriniidae) (Beran et al. 2014) and Macrocheles saceri Costa 1967 (Mesostigmata: Macrochelidae) (Niogret et al. 2006). ...
... This approach also dis- plays its usefulness and further progress in the field of entomology ( Friedrich et al. 2014). The use of non- destructive inspection of materials was implemented, for instance, for the identification of different social castes in nests (Aguilera-Olivares et al. 2017) and for tracking the movement of insects inside nests ( Johnson et al. 2004;Jennings & Austin 2011). ...
... While the lack of intraspecific agonistic behavior has been reported in some subterranean termites, there are also a number of studies demonstrating immediate agonistic interspecific interactions (Pickens 1934, Cornelius and Osbrink 2003, Messenger and Su 2005. Furthermore, agonistic behaviors by workers and soldiers toward alate nestmates were reported in a number of termite species if they return to their colony of origin following a nuptial flight (Grasse andNoirot 1946, 1960;Luscher 1952;Ratcliffe et al. 1952;Buchli 1961;Thorne and Haverty 1991;Aguilera-Olivares et al. 2016). ...
... The presence of M. carbonarius and G. sulphureus extracts enabled M. gilvus to recognize them as isolated chemical cues other than their own. In nature, the presence of different cuticular compounds in one-piece nesting termites causes avoidance, and they become aggressive 34 . Specific species, such as M. gilvus, respond to the situation with some level of alarm or avoidance even at a different distances from their colonies 35 . ...
... Although the trumpet plants contain tropane alkaloids, which are toxic to insects (Arab et al., 2012), this study suggests that D. speciosa and M. trivialis have developed defense mechanisms. Even if the mechanisms are not well understood, it is likely that the plant's alkaloids are ingested and kidnapping, as already evidenced for A. grossa in trumpet plants (Pinto et al., 2016). ...
... Species belonging to the treehopper tribe Hoplophorionini exhibit extended maternal care (i.e., maternal care is observed through the egg and almost all nymphal stages) and have been suggested in general to be semelparous (Wood 1974;Godoy et al. 2006;Lin 2006), except for A. grossa, which has been proposed as a moderately iteroparous species (Torrico-Bazoberry et al. 2014). A. grossa exhibits maternal care until at least the third nymphal instar including feeding facilitation towards newly hatched nymphs (Torrico-Bazoberry et al. 2016). ...
