Abstract:

Introduction. Asymmetric omphalopagus is a rare situation of conjoined twinning, in which a grossly defective twin is attached to the thorax and upper abdomen of the main twin. We describe a case of an asymmetric omphalopagus accompanied by a normal triplet after assisted reproductive technology (ART) and tried to further characterize the all aspects of the conjoined twins. Case Presentation: Perioperative diagnostic imaging was carried out followed by an autopsy to evaluate all aspects of the parasite accompanied by histological, immunohistochemical, and molecular biological evaluation. The parasite had well-developed lower extremities as well as upper extremities with a cleft hand syndrome. The sex was nondeterminable, but DNA fingerprinting revealed that both parasite and autosite are monozygotic, so are females. There was no sign of any axial skeleton or central nervous system. We found a rudimentary rectum with a nonpervious anus, a kidney, ureter, urinary bladder, and a blind-ending urethra. The blood supply of the parasite was connected to the vessel system of the autosite. Conclusions. To our knowledge, only two cases of parasitic omphalopagus after ART have been described to date. Altogether, 52 cases have been reported, and in most of them, the parasites were successfully separated.

Abstract:

Cervical cancer (CC) continues to be a major public health problem in Mexico, ranking second among cancers in women. A persistent infection with human papillomaviruses (HPV) is the main risk factor for CC development. In addition, a significant fraction of other cancers including those of the anus, oropharynx, and penis are also related to HPV infection. In CC, HPV-16 is the most prevalent high-risk HPV type, followed by HPV-18, both being responsible for 70% of cases. HPV intratype variant lineages differ in nucleotide sequences by 1–10%, while sublineages differ by 0.5–1%. Several studies have postulated that the nucleotide changes that occur between HPV intratype variants are reflected in functional differences and in pathogenicity. Moreover, it has been demonstrated that HPV-16 and -18 intratype variants differentially affect molecular processes in infected cells, changing their biological behavior that finally impacts in the clinical outcome of patients. Mexico has participated in providing knowledge on the geographical distribution of intratype variants of the most prevalent HPVs in premalignant lesions of the cervix and cervical cancer, as well as in other HPV-related tumors. In addition, functional studies have been carried out to assess the cellular effects of intratype variations in HPV proteins. This review addresses the state of the art on the epidemiology of HPV-16 and HPV-18 intratype variants in the Mexican population, as well as their association with persistence, precancer and cervical cancer, and functional aspects related to their biological behavior.

Abstract:

Natural Orifice Transluminal Endoscopic Surgery (NOTES) involves accessing the abdominal cavity via one of the bodies’ natural orifices, for example, mouth, anus, or vagina. This new surgical procedure is very appealing from patients’ perspectives because it eliminates completely abdominal wall aggression and promises to reduce postoperative pain, in addition to all other advantages brought by laparoscopic surgery. However, the constraints imposed by both the mode of access and the limited technology currently available make NOTES very challenging for the surgeons. Redesign of the instruments is imperative in order to make this emerging operative access safe and reproducible. In this paper, we survey on the state-of-the-art devices used in NOTES and introduce both the flexible instruments based on improvement of current endoscopic platforms and the revolutionary concept of robotic platforms based on the convergence of communication and micromechatronics technologies. The advantages and limitations of each category are addressed. Potential solutions are proposed to improve the existing designs and develop robust and stable robotic platforms for NOTES.

Abstract:

Zusammenfassung Hintergrund Kolorektale Fremdkörper sind ein nicht ungewöhnlicher Vorstellungsgrund in der Notaufnahme. Die häufig erst verspätete ärztliche Konsultation führt möglicherweise zu einer erhöhten Rate an Komplikationen. Vor jeder rektalen Manipulation sollte die Art des Fremdkörpers bekannt sein. Trotz Lokalisation im Rektum kann die Entfernung des Fremdkörpers schwierig sein und eine Narkose erfordern. Verletzungen sollten nach jeder Intervention ausgeschlossen werden. Methoden Retrospektiv wurden die Fälle mit der Diagnose „Fremdkörper im Anus und Rektum (inkl. Sigmoid)“ zwischen 2002 und 2017 ausgewertet. Von 56 Patienten konnten 33 (59%) Patienten in die Studie eingeschlossen werden. Zusätzlich wurde eine Literaturrecherche mit den Suchbegriffen „colon AND foreign bod*“, „rectum AND foreign bod*“ und „colorectal AND foreign bod*“ in den Datenbanken PubMed (1623) und Cochrane Libary (17) sowie in der Suchmaschine Google Scholar (300) vorgenommen. Ergebnisse Durchschnittlich erfolgte die Vorstellung nach 33 h. Eine Entfernung in der Notaufnahme gelang in 2 Fällen (6%). 31 Patienten (94%) benötigten eine Narkose. Eine notfallmäßige Laparotomie wurde in 3 Fällen (9%) vorgenommen. Komplikationen traten nicht auf. Die Entlassung erfolgte im Schnitt nach 1,5 d. Schlussfolgerung Eine verspätete Vorstellung führt nicht zu einem komplizierteren Verlauf. Nach abschließender Rektoskopie ist eine weitere Bildgebung nicht erforderlich. Eine kurzzeitige Überwachung ist nach unauffälliger Klinik ausreichend.

Abstract:

Ant- and ant-colony-inspired ALife art is characterized by the artistic exploration of the emerging collective behavior of computational agents, developed using ants as a metaphor. We present a chronology that documents the emergence and history of such visual art, contextualize ant- and ant-colony-inspired art within generative art practices, and consider how it relates to other ALife art. We survey many of the algorithms that artists have used in this genre, address some of their aims, and explore the relationships between ant- and ant-colony-inspired art and research on ant and ant colony behavior.

Abstract:

This paper addresses the hypothetical relationship of photography and so-called pheromone maps created by an artificial life system that simulates an ant colony and causes its activity to evolve based on the contours of images. Pheromone—used by ants to communicate via the environment—is also simulated, and from the communication and interaction of the swarm with the environment (an image) there results a kind of drawing made with the simulated pheromone. Since ants are able to detect the edges of the image, the outcome is a sketch that resembles the original image, as with old camera obscura drawings. This text explores the observable traits shared by the photographic process and the swarm's pheromone maps. The theme is discussed in the context of the emergent artificial art research field; recent theoretical advances that link swarm intelligence and cognitive sciences are also addressed.

Abstract:

Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. Although most HPV infections will spontaneously resolve, a considerable proportion of them will persist, increasing the risk of anogenital dysplasia, especially within certain populations, such as patients infected with human immunodeficiency virus (HIV). Furthermore, high-risk oncogenic HPV types (HR-HPV) are the main cause of cervix and other anogenital cancers, such as cancer of the vagina, vulva, penis, or anus. HIV and HPV coinfection is common among people living with HIV (PLWH) but disproportionally affects men who have sex with men (MSM) for whom the rate of persistent HPV infection and reinfection is noteworthy. The molecular interactions between HIV and HPV, as well as the interplay between both viruses and the immune system, are increasingly being understood. The immune dysfunction induced by HIV infection impairs the rate of HPV clearance and increases its oncogenic risk. Despite the availability of effective antiretroviral therapy (ART), the incidence of several HPV-related cancers is higher in PLWH, and the burden of persistent HPV-related disease has become a significant concern in an aging HIV population. Several public health strategies have been developed to reduce the transmission of HIV and HPV and mitigate the consequences of this type of coinfection. Universal HPV vaccination is the most effective preventive tool to reduce the incidence of HPV disease. In addition, screening programs for HPV-related cervical and vulvovaginal diseases in women are well-recognized strategies to prevent cervical cancer. Similarly, anal dysplasia screening programs are being implemented worldwide for the prevention of anal cancer among PLWH. Herein, the main epidemiological features and clinical implications of HIV and HPV coinfection are reviewed, focusing mainly on the relationship between HIV immune status and HPV-related diseases and the current strategies used to reduce the burden of HPV-related disease.

Abstract:

Abstract Three to four dominant seed-transporting ant species of different size categories (Tetramorium caespitum, Lasius niger, Formica rufibarbis/Formica pratensis) on the plateau of abandoned ore sedimentation basin (tailings containment) were studied as pioneer and subsequent colonisers of this industrial waste deposit, from the viewpoint of their functioning in plant seed dispersal. We examined the role of ants in primary vegetation succession. Experiments of seed removal by ants with plant species found within close proximity of tailings were related to the succession. Ant activity generates a considerable shift in the quality of the colonised surface, as they collectively act as ecosystem engineers

Abstract:

In this work, we formulate and solve a new type of approximate nearest neighbor search (ANNS) problems called ANNS after linear transformation (ALT). In ANNS-ALT, we search for the vector (in a dataset) that, after being linearly transformed by a user-specified query matrix, is closest to a query vector. It is a very general mother problem in the sense that a wide range of baby ANNS problems that have important applications in databases and machine learning can be reduced to and solved as ANNS-ALT, or its dual that we call ANNS-ALTD. We propose a novel and computationally efficient solution, called ONe Index for All Kernels (ONIAK), to ANNS-ALT and all its baby problems when the data dimension d is not too large (say d ≤ 200). In ONIAK, a universal index is built, once and for all, for answering all future ANNS-ALT queries that can have distinct query matrices. We show by experiments that, when d is not too large, ONIAK has better query performance than linear scan on the mother problem (of ANNS-ALT), and has query performances comparable to those of the state-of-the-art solutions on the baby problems. However, the algorithmic technique behind this universal index approach suffers from a so-called dimension blowup problem that can make the indexing time prohibitively long for a large dataset. We propose a novel algorithmic technique, called fast GOE quadratic form (FGoeQF), that completely solves the (prohibitively long indexing time) fallout of the dimension blowup problem. We also propose a Johnson-Lindenstrauss transform (JLT) based ANNS-ALT (and ANNS-ALTD) solution that significantly outperforms any competitor when d is large.

Abstract:

In the current work, we consider the applicability of Ant Colony Systems (ACS) to the bankruptcy prediction problem. ACS are nature-based algorithms that mimic the functions of live organisms to find the best performing solution. In our work, ACS are used for the extraction of classification rules for bankruptcy prediction. An experimental study was conducted in order to evaluate the performance of the system and identify well performing parameters. Results were compared to the performance obtained by state-of-the-art methods for classification, namely the Artificial Neural Networks, the Support Vector Machines, the Partial Decision Trees and the Fuzzy Lattice Reasoning. Comparison indicates the high performance of the ACS which is further supported by their ability to extract classification rules, thus offering interpretation of the prediction results. The latter is of great importance in the field of corporate distress where no unified theory on distress prediction exists. Most studies with distress prediction have focused on increasing the accuracy of the model and have not always paid attention to the model interpretation.

Full text

Abstract:

Habitat complexity is a major determinant of structure and diversity of ant assemblages. Following the size-grain hypothesis, smaller ant species are likely to be advantaged in more complex habitats compared to larger species. Habitat complexity can act as an environmental filter based on species size and morphological traits, therefore affecting the overall structure and diversity of ant assemblages. In natural and semi-natural ecosystems, habitat complexity is principally regulated by ecological successions or disturbance such as fire and grazing. Urban ecosystems provide an opportunity to test relationships between habitat, ant assemblage structure and ant traits using novel combinations of habitat complexity generated and sustained by human management. We sampled ant assemblages in low-complexity and high-complexity parks, and high-complexity woodland remnants, hypothesizing that (i) ant abundance and species richness would be higher in high-complexity urban habitats, (ii) ant assemblages would differ between low- and high-complexity habitats and (iii) ants living in high-complexity habitats would be smaller than those living in low-complexity habitats. Contrary to our hypothesis, ant species richness was higher in low-complexity habitats compared to high-complexity habitats. Overall, ant assemblages were significantly different among the habitat complexity types investigated, although ant size and morphology remained the same. Habitat complexity appears to affect the structure of ant assemblages in urban ecosystems as previously observed in natural and semi-natural ecosystems. However, the habitat complexity filter does not seem to be linked to ant morphological traits related to body size.

Abstract:

The degree to which competition by dominant species shapes ecological communities remains a largely unresolved debate. In ants, unimodal dominance–richness relationships are common and suggest that dominant species, when very abundant, competitively exclude non-dominant species. However, few studies have investigated the underlying mechanisms by which dominant ants might affect coexistence and the maintenance of species richness. In this study, we first examined the relationship between the richness of non-dominant ant species and the abundance of a dominant ant species, Formica subsericea, among forest ant assemblages in the eastern US. This relationship was hump-shaped or not significant depending on the inclusion or exclusion of an influential observation. Moreover, we found only limited evidence that F. subsericea negatively affects the productivity or behavior of non-dominant ant species. For example, at the colony-level, the size and productivity of colonies of non-dominant ant species were not different when they were in close proximity to dominant ant nests than when they were away and, in fact, was associated with increased productivity in one species. Additionally, the number of foraging workers of only one non-dominant ant species was lower at food sources near than far from dominant F. subsericea nests, while the number of foragers of other species was not negatively affected. However, foraging activity of the non-dominant ant species was greater at night when F. subsericea was inactive, suggesting a potential mechanism by which some non-dominant species avoid interactions with competitively superior species. Gaining a mechanistic understanding of how patterns of community structure arise requires linking processes from colonies to communities. Our study suggests the negative effects of dominant ant species on non-dominant species may be offset by mechanisms promoting coexistence.

Abstract:

Abstract Field tests were conducted in ant infested apartments to determine the efficacy of Combat ant bait in plastic bait stations. Bait station placement was dependent upon species specific foraging behavior. For species exhibiting strong to moderate trail following (Argentine, odorous house, thief, and acrobat ants), two bait stations were placed within 5 cm of the trail, approximately 0.5 m apart. The red imported fire ant showed no trail-following in apartments. Two baits were placed 0.5 m apart in areas with ant densities of ≥5 ants per 5 cm2. Bait efficacy was evaluated by determining the reduction in foraging activity 3 d after baiting and by determining if the colony was dead or alive. Foraging activity was determined during daylight hours by counting the number of ants crossing a line drawn across the foraging trail in 5 min, or by counting the total number of ants in a 30 by 30 cm area. Reduction in foraging activity was calculated as the % change in activity. Colonies were located and flagged prior to treatment. There were 10 replicate colonies of each ant species. Baits were examined for evidence of feeding 3 d after treatment.

Abstract:

The behaviour and development of Elasmosoma sp., near pergandei Ashm. (Neoneurinae: Braconidae: Hymenoptera), a parasite of the ant, Formica obscuriventris clivia Creighton, was studied in a coastal sand dune habitat in central Oregon over a 2-year period. Female wasps oviposited into the abdomen of major worker ants after alighting briefly on the host. Embryonic development of the wasp occurred inside the serosal membrane or trophamnion of the egg in the abdomen of the ant host. First instar wasp larvae possessed a large head capsule with falcate mandibles, 11 ventral body lobes, an elongate tail and a dorsally located anus. Second instar larvae were unspecialized and lacked the large head capsule, elongate tail and paired ventral body lobes. Third instar larvae were hymenopteriform with a distinct head capsule. Cocoon formation and adult emergence is described. Observations on the percentage parasitism and altered behaviour of parasitized ants are presented. The association between neoneurine wasps and ants is a well-balanced system that has been in existence for at least 40 million years.

Abstract:

Our aim was to investigate the foraging activity of native ants on tree trunks in accordance with their location in forest fragments and the presence or absence of the invasive antLasius neglectus. Trees were categorized as isolated, edge, or core trees according to their location in forest fragments. In invaded fragments,Lasius neglectushad the highest spatial-temporal tree visitation. Isolated trees were visited more and for a longer time by this invasive ant. Invaded fragments had low native ant activity on trees compared to fragments withoutL. neglectus. The few encountered native ant species showed a lower frequency of visitation and for less time in comparison with their spatial-temporal visitation in control fragments.Crematogaster scutellarisandTemnothorax lichtensteinivisited all tree categories in both fragments (invaded or control) butLasius grandisstayed for longer on isolated trees from control fragments. We conclude that in fragments invaded byLasius neglectus, the richness of native ant foraging on trees was negatively affected. Isolated trees close to roads could act as dispersal stepping stones forLasius neglectus.

Abstract:

Ant Colony Optimization (ACO) encompasses a family of metaheuristics inspired by the foraging behaviour of ants. Since the introduction of the first ACO algorithm, called Ant System (AS), several ACO variants have been proposed in the literature. Owing to their superior performance over other alternatives, the most popular ACO algorithms are Rank-based Ant System (ASRank), Max-Min Ant System (MMAS) and Ant Colony System (ACS). While ASRank shows a fast convergence to high-quality solutions, its performance is improved by other more widely used ACO variants such as MMAS and ACS, which are currently considered the state-of-the-art ACO algorithms for static combinatorial optimization problems. With the purpose of diversifying the search process and avoiding early convergence to a local optimal, the proposed approach extends ASRank with an originality reinforcement strategy of the top-ranked solutions and a pheromone smoothing mechanism that is triggered before the algorithm reaches stagnation. The approach is tested on several symmetric and asymmetric Traveling Salesman Problem and Sequential Ordering Problem instances from TSPLIB benchmark. Our experimental results show that the proposed method achieves fast convergence to high-quality solutions and outperforms the current state-of-the-art ACO algorithms ASRank, MMAS and ACS, for most instances of the benchmark.

Abstract:

Inspired from the fact that the real world ants from within a colony are not clones (although they may look alike, they are different from one another), in this paper, the authors are presenting an adapted ant colony optimisation (ACO) algorithm that incorporates methods and ideas from genetic algorithms (GA). Following the first (introductory) section of the paper is presented the history and the state of the art, beginning with the stigmergy and genetic concepts and ending with the latest ACO algorithm variants as multiagent systems (MAS). The rationale and the approach sections are aiming at presenting the problems with current stigmergy-based algorithms and at proposing a (possible - yet to be fully verified) solution to some of the problems ("synthetic genes" for artificial ants). A model used for validating the proposed solution is presented in the next section together with some preliminary simulation results. Some of the conclusions regarding the main subject of the paper (synthetic genes: agents within the MAS with different behaviours) that are closing the paper are: a) the convergence speed of the ACO algorithms can be improved using this approach; b) these "synthetic genes" can be easily implemented (as local variables or properties of the agents); c) the MAS is self-adapting to the specific problem that needs to be optimized.

Abstract:

Livestock production models prevailing in Colombian Andes are simplified treeless pastures for extensive ranching, with the consequent reduction of environmental services, such as seed dispersal, due to lack of primary dispersers, scarcity of adequate sites for seedling establishment and competition with grasses. This study evaluated if, in these harsh environments, ants can promote the colonization of arboreal species through directed dispersion of seeds towards the nests. Ten seeds of each species were offered to ants in six grazing pastures. Ants removed 25% of the seeds (1827) in 48 hours. Preference for arillated and small-to-medium sized seeds, such asPithecellobium dulce, andGuazuma ulmifolia, was observed.Cyphomyrmex major, Ectatomma ruidum, Solenopsis geminataandAtta cephaloteswere the key ant species in seed removal. It was concluded that functional ant groups present in the pastures could contribute to secondary dispersion of seeds with potential for restoration.

Abstract:

Many animals direct assistance selectively toward relatives and/or aggression toward non-relatives; the ability to differentiate between kin and non-kin should evolve when doing so incurs fitness benefits. We detail a field-based experiment that tests whether workers of a large-bodied, abundant, and hardy seed-harvester ant are capable of kin recognition. We use this exercise in an undergraduate animal-behavior class to introduce concepts associated with eusocial insects and the study of kin recognition, as well as to reinforce principles of hypothesis testing, experimental design, and scientific writing. Students collect data, analyze and interpret results, and write a formal report; this experiment is one of several we use as models to prepare students for designing and performing their own follow-up studies.

Abstract:

Abstract Ants have been suggested as one of many population pressures sea turtles face potentially affecting nesting-beach survival of eggs and hatchlings. However, little is known about the extent to which ants act as incidental or primary mortality factors. Most research has focused on New World fire ants (genus Solenopsis), with confirmed records of other ant species interactions with sea turtle nests in situ being rare. Our study documented the ant species associated with loggerhead sea turtle Caretta caretta (Linnaeus) (Testudines: Cheloniidae) nests in Georgia and determined if ant presence was linked to lower hatching or emergence success. Samples (n = 116) collected from sea turtle nests on eight islands contained 14 ant species including Solenopsis invicta Buren (Hymenoptera: Formicidae), the red imported fire ant, which was the most common ant species encountered. Ant presence was not correlated with lower hatching success, but when other known disturbances were removed, correlated with significantly lower nest emergence success (P < 0.0001). Logistic modeling suggests that proximity of sea turtle nests to the primary dune significantly increases risk of ant predation on hatchling sea turtles. Population managers can reduce this risk by maintaining a 1-m buffer shoreward between dune vegetation and relocated sea turtle nests. Our results suggest that ants may exert a density-dependent pressure on nesting sea turtle populations and call for additional investigations to determine if managing native and invasive ants augments other efforts to improve hatchling survival.

Abstract:

Division of labour is central to the ecological success of eusocial insects, yet the evolutionary factors driving increases in complexity in division of labour are little known. The size–complexity hypothesis proposes that, as larger colonies evolve, both non-reproductive and reproductive division of labour become more complex as workers and queens act to maximize inclusive fitness. Using a statistically robust phylogenetic comparative analysis of social and environmental traits of species within the ant tribe Attini, we show that colony size is positively related to both non-reproductive (worker size variation) and reproductive (queen–worker dimorphism) division of labour. The results also suggested that colony size acts on non-reproductive and reproductive division of labour in different ways. Environmental factors, including measures of variation in temperature and precipitation, had no significant effects on any division of labour measure or colony size. Overall, these results support the size–complexity hypothesis for the evolution of social complexity and division of labour in eusocial insects. Determining the evolutionary drivers of colony size may help contribute to our understanding of the evolution of social complexity.

Quando Varèse morou naquela rua sessenta anos antes, ele criou o Poème Electronique, uma obra comissionada pela empresa Philips. A música de oito minutos se tornaria a trilha sonora do pavilhão criado por Le Corbusier para a Feira Mundial de Bruxelas de 1958. Para essa composição, Varèse reuniu sons triviais de Eindhoven –– para muitos, ruídos que seriam apenas sons descartáveis da vida cotidiana. Esbanjando muita atenção e sensibilidade, o compositor enxergou algo poético nesses sons e produziu uma composição impressionante. Nesta pesquisa, seguimos um caminho semelhante: avaliar o que parece insignificante para muitos. No primeiro dia em Eindhoven, o simpático coordenador de tecnologia do Van Abbemuseum Peter Classen entregou a Moreschi um pen drive com 654 imagens das obras da coleção do museu que estavam em exibição (nas mostras The Making Of Modern Art e The Way Beyond Art). Via internet, as imagens foram enviadas para Pereira, que já sabia exatamente o que fazer com elas, assim que as recebeu. [...]

Abstract:

In this paper I argue that Walter Pater, in both his critical and creative work, is a liminal writer along the lines set out by Angus Fletcher in his studies of Edmund Spenser and S.T. Coleridge. Fletcher suggests that personification or prosopopoeia (literally "person-making") results from "thresholdness", and I relate this observation not only to Pater's employment of personification, e.g. "art comes professing frankly", but his tendency to equate works of art with persons and vice-versa. Pater's work focuses on transitional eras of culture and on transitional minds, historical, semi-historical and imaginary, as in his "Imaginary Portraits". I argue that it is because of Pater's constant transition from experience to experience, his constant in-between state, that he invents characters which are neither wholly allegorical personifications nor fleshed out humans; that he tends to associate aesthetic experience with "the face of one's friend"; and that his work hovers between the creative and the critical.

Abstract:

AbstractThe cerrado savanna of Brazil embraces an area of approximately 2 million km2, in which vegetation physiognomies may vary from open grassland to forest with a discontinuous herbaceous layer. Here we describe the main ecological factors accounting for the prevalence of ants on cerrado foliage, and present a general characterization of the arboreal ant fauna of this savanna. The high incidence of ants on cerrado foliage results mostly from the wide occurrence of predictable liquid food sources in the form of extrafloral nectaries (EFNs) and insect honeydew, which act as efficient promoters of ant activity on vegetation. In addition, stem galleries and cavities constructed by boring beetles and insect galls create a nesting space frequently used by arboreal ants. Specific studies involving ants, herbivores and plants are reported to demonstrate the impact that foliage-dwelling ants can have on phytophagous insects, herbivory levels, and ultimately on host plants. These studies show that: (i) ants visit EFNs and likely benefit from this resource; (ii) EFN-gathering ants can benefit particular plant species by reducing herbivory and increasing plant fitness; (iii) presence of EFNs does not affect ant species richness within a given tree; (iv) there is not a particular ant species composition typical of plants with EFNs; (v) although plants with EFNs are visited by more ant individuals than non-nectariferous plants, this visitation pattern does not translate into lower numbers of herbivores on the nectariferous plant community. We suggest some promising research avenues to elucidate how community-level parameters can be tied to the ecology of ant-plant associations in cerrado.

Abstract:

Reflecting on a pandemic-possible production of David Paquet’s The Weight of Ants, Yung shares some glimpses of what went on behind-the-screens. Beyond the topical interest that this ‘made-in-pandemic’ production might offer readers, Yung takes up some themes important to Paquet’s play to discuss ways forward. How do we emerge from this chrysalis, transformed, embodying a new form of living? At the intersection of climate crisis and decolonization, what if we now only make art with an ecological impact proportional to its ecological relevance? What if the forms of storytelling we need to embrace are not digital, but indigenous, relational, and low- or no-waste?
