Abstract (sommario):

The role of cannibalism in crayfish populations is not well understood, despite being a potentially key density-dependent process underpinning population dynamics. We studied the incidence of cannibalism in an introduced signal crayfish Pacifastacus leniusculus population in a Scottish lowland river in September 2014. Animals were sampled using six different sampling techniques simultaneously, revealing variable densities and size distributions across the site. Cannibalism prevalence was estimated by analysing the gut contents of crayfish >20 mm CL for the presence of crayfish fragments, which was found to be 20% of dissected individuals. When seeking evidence of relationships between the sizes of cannibals and ‘prey’, the density of conspecifics <56% the size of a dissected individual yielded the best fit. The relationship between cannibalism probability and crayfish size and density was equally well described by three different metrics of crayfish density. Cannibalism increased with crayfish size and density but did not vary according to sex. These results suggest that large P. leniusculus frequently cannibalize smaller (prey) conspecifics, and that the probability of cannibalism is dependent upon the relative size of cannibal-to-prey and the density of the smaller crayfish. We suggest that removing large individuals, as targeted by many traditional removal techniques, may lead to reduced cannibalism and therefore a compensatory increase in juvenile survival.

Abstract (sommario):

Cannibalism is ubiquitous in nature and especially pervasive in consumers with stage-specific resource utilization in resource-limited environments. Cannibalism is thus influential in the structure and functioning of biological communities. Parasites are also pervasive in nature and, we hypothesize, might affect cannibalism since infection can alter host foraging behaviour. We investigated the effects of a common parasite, the microsporidian Pleistophora mulleri , on the cannibalism rate of its host, the freshwater amphipod Gammarus duebeni celticus . Parasitic infection increased the rate of cannibalism by adults towards uninfected juvenile conspecifics, as measured by adult functional responses, that is, the rate of resource uptake as a function of resource density. This may reflect the increased metabolic requirements of the host as driven by the parasite. Furthermore, when presented with a choice, uninfected adults preferred to cannibalize uninfected rather than infected juvenile conspecifics, probably reflecting selection pressure to avoid the risk of parasite acquisition. By contrast, infected adults were indiscriminate with respect to infection status of their victims, probably owing to metabolic costs of infection and the lack of risk as the cannibals were already infected. Thus parasitism, by enhancing cannibalism rates, may have previously unrecognized effects on stage structure and population dynamics for cannibalistic species and may also act as a selective pressure leading to changes in resource use.

Abstract (sommario):

AbstractFilial cannibalism, eating one's own viable offspring, is accepted as an adaptive response to trade-offs between current and future reproduction. Theoretical models predict that high mate availability may induce more filial cannibalism, but this prediction is rarely tested. To examine this prediction, we performed laboratory experiments using the nest breeding goby Rhinogobius flumineus. Subject males were allowed to mate with a gravid female and care for the broods. A separate gravid female housed in a small cage (stimulus-female) was shown to the subject males at one of three different points during the brood cycle: prior to spawning, within 1 day after spawning and 1 week after spawning. Empty cages were shown as a control. Males that were shown the stimulus-female before spawning cannibalised more eggs than control males. In contrast, males that were shown the stimulus-females after spawning cannibalised as few eggs as control males did. Additionally, males that were shown the stimulus-female prior to spawning did not court females more intensively than other males. Thus, we suggest that the presence of an additional mate, rather than energy expenditure associated with courtship directed toward an additional mate, can facilitate males to cannibalise their eggs.

Abstract (sommario):

AbstractEgg cannibalism serves various functions in the Coccinellidae. Here we examined the fitness consequences of egg cannibalism by neonates, fourth instar larvae, and prereproductive adults of Coleomegilla maculata DeGeer, with beetles fed a diet of Ephestia kuehniella Zeller eggs. Cannibalism of two eggs by neonates had no effect on development, and cannibalism of five eggs by fourth instars did not benefit any aspect of reproduction, but delayed pupation slightly. Cannibalism of eggs by pre-reproductive adults had no effect on reproductive success in any combination of reciprocal crosses of cannibals and non-cannibals. Females did not recognize, nor avoid consuming, their own clutches, and cannibalism propensity did not change following mating and onset of oviposition in either sex. These results contrast with those for more strictly aphidophagous species in which larvae gain developmental benefits, and females may recognize and avoid filial egg clusters while using cannibalism to interfere with conspecific females, whereas males reduce egg cannibalism after mating because they cannot recognize filial clusters. Egg cannibalism may confer developmental benefits to C. maculata when diet is suboptimal, as previously shown, but no such benefits were evident on the high-quality E. kuehniella egg diet. Female C. maculata do not require aphids to reproduce and distribute their eggs broadly in the environment, given that larvae can develop on pollen and non-aphid prey. Thus, C. maculata is not subject to the intraspecific competition that selects for cannibalism in more aphidophagous species, and also lacks many secondary adaptations associated with the behaviour.

Abstract (sommario):

Ballads actively shaped contemporary popular mentalities and through analysing ballads historians are presented with a world of propaganda and persuasion, aimed at a broad spectrum of society from literate to illiterate. Nineteenth-century ballads describing shipwrecks highlight the moral ambiguities present in extreme life-or-death situations. Many such ballads teach that survival cannibalism was rational, pragmatic, civilised and should be actively encouraged. This article demonstrates how ballads placed cannibalism into a chivalrous context, allowed sailors to vicariously experience the events thereby learning a prescribed ‘ritual’ to follow and made breaking the anthropophagic taboo socially acceptable, even virtuous. In fictitious ballad narratives, cannibalism is a test of virtue as one person offers their body as sustenance to preserve a starving friend. It is not a horrific departure from civilised attitudes, but a heroic self-sacrifice. Ballads recounting real events of shipwreck cannibalism helped to promote the ‘civilised cannibalism’ ritual of drawing lots to select the victim, placing anthropophagy within a democratic, equitable process. Shipwreck cannibalism ballads offer a contrast to other European descriptions of cannibalism, as the sailor-cannibals are never presented with any of the traits associated with the imagined, non-European cannibal of colonial discourse.

Testo completo

Abstract (sommario):

Infanticide and offspring cannibalism are taxonomically widespread phenomena. In some group-living species, a new dominant individual taking over a group can benefit from infanticide if doing so induces potential mates to become reproductively available sooner. Despite widespread observations of infanticide (i.e. egg cannibalism) among fishes, no study has investigated whether egg cannibalism occurs in fishes as a result of group takeovers, or how this type of cannibalism might be adaptive. Using the cooperatively breeding cichlid, Neolamprologus pulcher , we tested whether new unrelated males entering the dominant position in a social group were more likely to cannibalize eggs, and whether such cannibalism would shorten the interval until the female's next spawning. Females spawned again sooner if their broods were removed than if they were cared for. Egg cannibalism occurred frequently after a group takeover event, and was rarer if the original male remained with the group. While dominant breeder females were initially highly aggressive towards newcomer males that took over the group, the degree of resistance depended on relative body size differences between the new pair and, ultimately, female aggression did not prevent egg cannibalism. Egg cannibalism, however, did not shorten the duration until subsequent spawning, or increase fecundity during subsequent breeding in our laboratory setting. Our results show that infanticide as mediated through group takeovers is a taxonomically widespread behaviour.

Abstract (sommario):

Cannibalism by larval walleye (Stizostedion vitreum) was studied to determine the ecological consequences and implications of cohort cannibalism in intensive culture systems and in natural communities. Two categories of cannibalistic behavior were observed. Trunk attacks were the most frequent (92%), and nearly always (98%) resulted in the escape of the victim; however, victims suffered a 19% mortality rate within 24 h of the attack. Tail attacks were less frequent but almost always resulted in ingestion of the victim. Tail attacks had a mean duration of 3.5 h and were more easily observed than trunk attacks (mean duration = 20 s). Under conditions of unlimited food, cannibalism could not be shown to confer an advantage in either growth or survival upon cannibals. The rate of cannibalism increased as food density decreased, but depended on the availability of light. Trunk attacks among larval walleye may be a higher source of mortality than the more commonly observed tail attack behavior.

Abstract (sommario):

The intracohort cannibalism present in tropical gar larvae (A. tropicus) generates great problems in its culture, as in other fish species around the world. The addition of tryptophan (Trp) (10, 20, and 30 g/kg) and a control diet (CD) without Trp were evaluated in A. tropicus larvae regarding growth, survival, cannibalism, behavior, digestive enzymatic activity, and genes related to aggressiveness and/or cannibalism in two stages: 0–13 days after hatching (DAH); and only cannibals (14–24 DAH). In the first stage, no differences were observed in growth parameters; cannibalism was lower with the use of Trp, with the lowest percentage being the 10 g/kg Trp treatment (56.75 ± 2.47%) compared to CD (64.75 ± 1.76%). In the second stage, survival was greater in 10 g/kg Trp (75.00 ± 7.07%) than in CD (23.33 ± 5.77%). Thus, cannibalism was lower with 10 g/kg Trp (20.0 ± 10.0%) compared to CD (76.66 ± 5.77%). Cannibal larvae fed with 10 g/kg Trp had a greater enzymatic activity in acid and alkaline proteases and leucine aminopeptidase, as well as the overexpression of avpi1, crh, and htr1a and the subexpression of tph1, th, sstr1, and hdc (p < 0.05). No aggressive behaviors were recorded in the larvae fed with the 10 g/kg Trp treatment, unlike those fed with CD. The use of 10 g/kg Trp improves survival and reduces cannibalism in A. tropicus larvae.

Abstract (sommario):

Abstract The Hebrew Bible contains multiple texts in which mothers eat their children. Deuteronomy 28, Lam 2 and 4, and 2 Kgs 6 all offer variations on the theme of maternal cannibalism. While these passages are often written off as gruesome, exceptional, or motivated by extreme necessity (such as starvation), such approaches miss the literary and ideological significance of maternal cannibalism. This study, in contrast, approaches the biblical accounts through another body of literature with its own rich assembly of cannibalistic mothers: the classic fairy tales. Reading with fairy tales surfaces four important points: (1) starvation is insufficient to explain cannibalism; (2) cooking children, as much as eating them, is narratively significant and should be analyzed as such; (3) some mothers are indeed Bad Mothers, even as (4) cannibalism does not preclude affection and love—including at least some mothers who cannibalize their children. Taken together, these principles challenge the assumed norms of maternity, while offering new ways of reading and responding to the cannibal mothers of the Hebrew Bible.

Abstract (sommario):

Cannibalism both fascinates and repels. The concept of the cannibal has changed and evolved, from the semi- or in-human anthropophagi of Classical texts to the ‘savage’ cannibals of colonial times, whose alleged aberrations served as a justification for invasion, conversion and extermination, to the contemporary cannibal driven often by psychosexual drives. Cannibal texts typically present the act as pervasive, aggressive and repulsive. If these parameters are admitted, alleged cannibals immediately fall outside normative European humanist morality. This paper examines cannibalism as a major delineator of the civilised human. Cannibals offer social scientists a handy milestone to confirm the constant improvement and progress of humanity. The idea that colonised peoples were not savage, degenerate cannibals threatens the concept of the ‘Great Chain of Being’, which was assumed to show an inexorable progress from plants to animals to humans, and upward toward the divine, led by enlightened Western civilisation. But cannibal mythology, factual or imaginary, offers an opportunity to re-evaluate the assumptions of human supremacism and see ourselves as edible, natural beings.

Abstract (sommario):

Les stratégies thérapeutiques anticancer sont nombreuses et variées. Elles visent à déclencher la mort des cellules tumorales mais les processus de mort cellulaire diffèrent en fonction du traitement, du type de cellule ciblé et des caractéristiques du patient. A côté des mécanismes classiques tels que l’apoptose et la nécrose, on retrouve également du cannibalisme cellulaire dans les biopsies de tumeurs des patients. Ce phénomène dont les mécanismes sont encore peu caractérisés, correspond à l’internalisation d’une cellule vivante par une cellule vivante. Il est fréquemment suivi par la dégradation de la cellule internalisée. Cette modalité de mort atypique est intéressante car nous avons montré qu’elle pouvait être modulée par des traitements anticancéreux et des études ont également démontré qu’elle pouvait servir de biomarqueur pronostique dans certains types de cancer. Ces travaux de thèse ont permis d'identifier des voies de signalisation cellulaire activées lors du déclenchement du cannibalisme cellulaire par les radiations ionisantes
Many types of anticancer therapies are available to kill tumor cells. The tumoral cell death modalities may be different upon the treatment, the cell type and inter-individual sensitivity. Besides the typical cell death processes apoptosis and necrosis, cellular cannibalism has also been reported in patients’ tumoral biopsies. This cellular process is defined as the engulfment of one live cell by another live cell followed by the degradation of the inner cell. The mechanisms beyond cellular cannibalism are still partially understoof but it appears to be of clinical relevance. Indeed, we have shown that these events could be modulated by anticancer treatments and there are evidences of their utility as a potent prognostic biomarker in some cancers. This thesis presents the in vitro experiments which led to the identification of the signaling pathways involved in cellular cannibalism induced by ionizing radiation

Abstract (sommario):

Scenes involving the breaking or outright inversion of culinary and (com)mensal norms are frequent in Greek art of the Archaic and Classical periods. The most discussed group of such images involves the uncivilized act of binge drinking unmixed wine and, as a result, losing control of one’s mind and body. Far less studied from an iconographic perspective are scenes of cannibalism, the most extreme and unsettling of all Greek culinary taboos. This paper seeks to define the iconography and meaning of cannibalism in Greek art through an exploration of the individual and shared compositional features of anthropophagic scenes and their visual relationship to normative images of meat consumption. Analytical attention will also be given to the objects on which these scenes appear and the relationship between the scenes and any other decorative content. Of particular interest is the way in which the iconography reflects cannibalism’s association with other serious normative violations, for example, infanticide (e.g., Prokne slaying her son Itys) and inhospitality (e.g., the Egyptian pharaoh Bousiris attempting to sacrifice his guest-friend Herakles). [The manuscript is currently being developed into an article to be submitted for publication consideration, probably in winter 2021.]

This thesis supports the Master of Fine Arts exhibition at the Tipton Gallery, East Tennessee State University, from March 23rd through April 3rd, 2009. To comment on the title of my thesis, it describes an invented process created to re-contextualize failed paintings into works that critically comment on the discipline of painting itself. The paper describes and analyzes the conceptual moves created by a refusal to be satisfied with predictable outcomes in my work. At the end of this tumultuous quest to explore what painting is to me, the most rewarding works were a product of a reconfigured failure. This paper also briefly discusses a period in the history of painting that is particularly relevant to my work, influential artists that I have continually returned in admiration, and collage techniques and materials used to create my work. An explanation of my current body of work is given at the end.

Abstract (sommario):

There is a conflict on the island of Rota in the Commonwealth of the Northern Mariana Islands between conservationists and the cultural traditions of Chamorro inhabitants. The traditional model of broadcasting media to a wide audience is not effective in intervening in environmental conflicts within indigenous communities compared to an emerging model of filmmaking that embraces local voices and perspectives. Historically, indigenous depictions in media tend to misrepresent "Others" in order to reinforce the imperialist interests of Western society. Within this essay I intend to analyze how Western media suppresses indigenous voice while investigating strategies for the creation of effective environmental films targeted towards specific local audiences. Awareness of the mistakes of filmmakers of the past combined with the availability of inexpensive production and distribution technologies will allow alternative models of filmmaking to portray a diversity of perspectives. Environmental films that feature indigenous voices allow local communities to define and strengthen their own cultural values while creating texts that broaden global understandings of the diversity of the human experience.

Testo completo

Abstract (sommario):

Cannibalism is a very common phenomenon throughout the animal kingdom. Females of the green dock leaf beetle, Gastrophysa viridula, lay clutches of eggs on the leaves of dock plants (Rumex species). Cannibalism takes the form of larvae eating unhatched conspecific eggs. Both within-clutch and inter-clutch cannibalism were observed. Within-clutch cannibalism was found to be of very limited extent. However, two observations indicated that cannibalism in G. viridula is more important than this finding might suggest. First instar larvae proved to be much more voracious cannibals when given an unlimited supply of newly laid eggs than when in normally hatching clutches. Also, viable as well as non-viable eggs were eaten from within clutches. The individual fitness benefits gained through cannibalism were studied. Larvae fed on eggs alone were unable to complete the first instar. But larvae given young eggs during their first instar along with dock leaves throughout all three instars did better in terms of survival and developmental rates than larvae fed only on dock leaves. No relationship was found between adult female size and lifetime egg production or longevity. Females were found to lay consecutively larger and smaller clutches throughout most of their lives. Mathematical models were used to interpret the results of a sperm competition experiment. The results were consistent with two mechanisms of sperm competition: linear transfer of sperm with time from male to female and sperm removal or repositioning with sperm mixing, or diminishing transfer of sperm with time and sperm mixing without displacement. The individual benefits of cannibalism in terms of survival observed in the laboratory were sufficient to satisfy Hamilton's inclusive fitness criterion for the evolution of selfish behaviour, even for the case of larvae eating full-siblings. It was anticipated that mechanisms may have evolved to reduce the risks of inter-clutch cannibalism. The distance from previously laid clutches that females lay their eggs was found to be important in this respect. and an intrinsic protective mechanism against cannibalism which becomes more effective with age was found. A possible link between this mechanism and chemical defence normally assumed to have evolved as a mechanism against inter-specific predation is suggested. It was found that the relative concentration of total oleic acid increased with age in G. viridula eggs, whereas the relative concentrations of all other major fatty acids declined or remained constant. The possible anti-cannibalistic role of oleic acid merits further investigation. The relationships between clutch size, asynchrony of hatching and the extent of within-clutch cannibalism were also studied. Asynchrony of hatching was found to increase with clutch size. Although negative relationships were found between hatching success of viable eggs and both clutch size and asynchrony of hatching, multiple regression showed that clutch size was the primary factor affecting the hatching success rate of viable eggs. An ability to distinguish between related and non-related eggs as victims was not found among first instar larvae. This finding is discussed in the light of individual and kin selection and the probability of encountering related eggs.

Abstract (sommario):

The article presents data on the current epizootic situation on Trichinella larvae infection in the jackal Canis aureus in view of its opportunistic feeding habits and wide geographical spread. To study the Trichinella infection of the jackal, three muscle groups were examined using the compression method. A total of 187 samples from 52 animals obtained in different ecological and geographical zones of the Krasnodar Territory (mountain zone in the Tuapsinsky District, foothill zone in the Seversky District, and flooded land in the Slavyansky District) were studied. It was found that the prevalence in the jackal was above 50% on average in all zones over two years of research. The highest infection rate in the jackal (81.5%) was recorded in the mountain zone; and significantly lower (about 40.0%) in the foothill zone and the flooded land. The invasion intensity rates were also the highest, on average 25.7±6.7 larvae/g in the mountain zone, 19.5±7.0 larvae/g in the foothill zone, and the lowest invasion intensity was observed in the flooded land, 6.5±3.7 larvae/g of muscle tissue. The mechanism of possible Trichinella transmission routes is due to trophic and chorological relationships between host species. The jackal with its opportunistic feeding habits, high abundance and movement activity provides these relationships with ecological manifestations as predation, necrophagy and cannibalism. Necrophagy and cannibalism are the most ecologically significant in the Krasnodar Territory.

Abstract (sommario):

There is a direct correlation between successful metamorphosis from larvae to post-larvae and the quality of the resultant juveniles or fry. Juvenile quality, in turn, is a major factor influencing fish production level and market price. However, following the profound morphological and physiological changes occurring during metamorphosis, the emerging juveniles in some species characteristically demonstrate heterotrophic growth, poor pigmentation, cannibalism and generally poor survival. The white grouper (Epinephelus aeneus) in Israel and the Pacific threadfin (Polydactylussexfilis) in Hawaii are two promising candidates for mariculture that have high market value but a natural fishery that has sharply declined in recent years. Unfortunately, their potential for culture is severely hampered by variable metamorphic success limiting their production. The main objective was to compare the efficacy and economic viability of dietary or environmental iodine on metamorphic success and juvenile quality in the white grouper and the pink snapper which would lead to improved commercial rearing protocols and increased production of these species both in Israel and the US. The Hawaii Institute of Marine Biology encountered problems with the availability of pink snapper brood stock and larvae and changed to Pacific threadfin or moi which is rapidly becoming a premier aquaculture species in Hawaii and throughout the Indo-Pacific. The white grouper brood stock at the National Center for Mariculture was lost as a result of a viral outbreak following the sudden breakdown of the ozone purification system. In addition, the NCM suffered a devastating fire in the fall of 2007 that completely destroyed the hatchery and laboratory facilities although the BARD project samples were saved. Nevertheless, by studying alternate species a number of valuable findings and conclusions that can contribute to improved metamorphosis in commercially valuable marine species resulted from this collaborative effort. The Israeli group found that exposing white grouper larvae to external TH levels synchronized and increased the rate of metamorphosis. This suggested that sub-optimal synthesis of TH may be a major factor causing size heterogeneity in the larval population and high mortality through cannibalism by their larger more metamorphosed cohorts. Two protocols were developed to enrich the larvae with higher levels of the TH precursor, iodine; feeding iodine enriched Artemia or increasing the level of seawater iodine the larvae are exposed to. Results of accumulated iodine in gilthead seabream larvae indicated that the absorption of iodine from the water is markedly more efficient than feeding iodine enriched Artemia nauplii. Samples for TH, which will be analyzed shortly, will be able to determine if another dietary factor is lacking to effectively utilize surplus tissue iodine for TH synthesis. Moreover, these samples will also clarify which approach to enriching larvae with iodine, through the live food or exposure to iodine enriched seawater is the most efficient and cost effective. The American group found that moi larvae reared in ocean water, which possessed substantially higher iodine levels than those found in seawater well water, grew significantly larger, and showed increased survival compared with well water reared larvae. Larvae reared in ocean water also progressed more rapidly through developmental stages than those in low-iodine well seawater. In collaboration with Israeli counterparts, a highly specific and precise radioimmunoassay procedure for thyroid hormones and cortisol was developed. Taken altogether, the combined Hawaiian and Israeli collaborative research suggests that for teleost species of commercial value, adequate levels of environmental iodine are more determinate in metamorphosis than iodine levels in the live zooplankton food provided to the larvae. Insuring sufficiently high enough iodine in the ambient seawater offers a much more economical solution to improved metamorphosis than enriching the live food with costly liposomes incorporating iodine rich oils.
