Wolves were a component of the Irish landscape until 1786 when the last one was killed. It had taken a concerted effort by Cromwell and his Government in Ireland to bring this about particularly through deforestation and landscape change, legislation, bounties and the efforts of a few professional wolf hunters. This paper estimates the wolf population in Ireland at three lime periods in the 1600s and examines how each of the forces already mentioned led to their eventual extermination. The 87 dated and documented wolf incidents which include wolf attacks on both animals and humans, wolf observations and the hunting and killing of wolves over the period 1560-1789 show both spatial and temporal variations.

Predators exert strong direct and indirect effects on ecological communities by intimidating their prey. Non-consumptive effects (NCEs) of predators are important features of many ecosystems and have changed the way we understand predator-prey interactions, but are not well understood in some systems. For my dissertation research I combined a variety of approaches to examine the effect of predation risk on herbivore foraging and reproductive behaviors in a coral reef ecosystem. In the first part of my dissertation, I investigated how diet and territoriality of herbivorous fish varied across multiple reefs with different levels of predator biomass in the Florida Keys National Marine Sanctuary. I show that both predator and damselfish abundance impacted diet diversity within populations for two herbivores in different ways. Additionally, reef protection and the associated recovery of large predators appeared to shape the trade-off reef herbivores made between territory size and quality. In the second part of my dissertation, I investigated context-dependent causal linkages between predation risk, herbivore foraging behavior and resource consumption in multiple field experiments. I found that reef complexity, predator hunting mode, light availability and prey hunger influenced prey perception of threat and their willingness to feed. This research argues for more emphasis on the role of predation risk in affecting individual herbivore foraging behavior in order to understand the implications of human-mediated predator removal and recovery in coral reef ecosystems.

The annual birthrate of female offspring and the intrinsic rate of natural increase (rmax) of populations are key reproductive parameters in models for assessing hunting sustainability or population viability of species. We calculated wild birthrate (pregnancy rate) for ten mammal species, using 180 months (from 2000 to 2015) of reproductive data from 950 hunted female animals collected with the participation of local hunters in the Peruvian Amazon. The methodology assured that no animals were killed outside the hunter's normal activities. The data included shows the reproductive state (pregnant or non-pregnant) of all collected individuals (n=1090), related to the date of collection. Hunters registered required data from genital organs from 950 (87.2%) hunted females, and 140 (12.8%) collected tracts lacked the collection date due to lost or non-legible individual sample codification.

The pressures on honeybee (Apis mellifera) populations, resulting from threats by modern pesticides, parasites, predators and diseases, have raised awareness of the economic importance and critical role this insect plays in agricultural societies across the globe. However, the association of humans with A. mellifera predates post-industrial-revolution agriculture, as evidenced by the widespread presence of ancient Egyptian bee iconography dating to the Old Kingdom (approximately 2400 bc)1. There are also indications of Stone Age people harvesting bee products; for example, honey hunting is interpreted from rock art2 in a prehistoric Holocene context and a beeswax find in a pre-agriculturalist site3. However, when and where the regular association of A. mellifera with agriculturalists emerged is unknown4. One of the major products of A. mellifera is beeswax, which is composed of a complex suite of lipids including n-alkanes, n-alkanoic acids and fatty acyl wax esters. The composition is highly constant as it is determined genetically through the insect’s biochemistry. Thus, the chemical ‘fingerprint’ of beeswax provides a reliable basis for detecting this commodity in organic residues preserved at archaeological sites, which we now use to trace the exploitation by humans of A. mellifera temporally and spatially. Here we present secure identifications of beeswax in lipid residues preserved in pottery vessels of Neolithic Old World farmers. The geographical range of bee product exploitation is traced in Neolithic Europe, the Near East and North Africa, providing the palaeoecological range of honeybees during prehistory. Temporally, we demonstrate that bee products were exploited continuously, and probably extensively in some regions, at least from the seventh millennium cal bc, likely fulfilling a variety of technological and cultural functions. The close association of A. mellifera with Neolithic farming communities dates to the early onset of agriculture and may provide evidence for the beginnings of a domestication process.

Since its excavation in the summer of 1973, El Niño cave has been considered a key site to understand the process of production economy and pottery technology introduction in South-eastern Iberian Peninsula, and especially to approach how such process could have affected people already settled in the Segura mountains. However, data from El Niño cave was very fragmentary, due to the lack of a broad study of Neolithic occupations of the site. In this paper, we present the analysis of pottery, lithic industry and faunal remains, as well as the existing dates from the site´s Holocene levels. The review of different evidence from the site allows suggesting that El Niño cave would have probably acted as a hunting and shepherding station, being a logistical site of larger places. However, limitations due to the fact that we are dealing with a 40- year-old excavation, prevent specifying how the process of Neolithic introduction in the Segura Mountains occurred.

Partiendo del concepto de metáfora cognitiva, que complementa al más conocido de metáfora literaria, y analizando la base conceptual que a ambas subyace, pretendemos un cuidadoso análisis de los textos de poesía épica y lírica arcaicas, sin olvidar la importancia fundamental del contexto cultural en que estos surgen, para obtener una mejor comprensión de la forma en que los griegos conceptualizaban el sentimiento amoroso.

El periplo de Hannón, frente a las propuestas que lo interpretan como una obra literaria, creemos que recoge un periplo auténtico, que sólo alcanzó cabo Juby y algunas de las Islas Canarias. Las refundaciones cartaginesas fueron todas en la Mauretania fértil, en los 7 primeros días de la expedición. Desde el islote de Kérne, en la expedición primó una primera exploración de evaluación, indicativo de que se trataba de apenas 2 o 3 barcos, con una tripulación limitada, que evitaban enfrentamientos con la población local. Los intérpretes Lixítai parecen conocer todos los puntos explorados, el río Chrétes, los etíopes del Alto Atlas costero, el gran golfo caluroso que finalizaba en el Hespérou Kéras, el volcán Theôn Óchema, o las gentes salvajes que denominaban Goríllai. Probablemente la mayor sorpresa fuese encontrar un volcán activo, emitiendo lava, que pudo ser la razón última para redactar este periplo. La falta de agua, alimentos y caza como razón para finalizar la expedición exploratoria sólo es comprensible en un trayecto corto que alcanzó hasta el inicio del desierto del Sahara. Otro tanto sucede con la ausencia de ríos importantes al Sur del río Chrétes, una clara prueba de que no se alcanzaron latitudes ecuatoriales y que los barcos se fueron alejando de la costa norteafricana.

Management of riverine and coastal ecosystems warrants enhanced understanding of how different stakeholders perceive and depend upon different kinds of ecosystem services. Employing a mixed methods approach, this study compares and contrasts the use and perceptions of upstream residents, downstream residents, tourism officials, and conservation organizations regarding the value of 30 ecosystem services provided by the Wami River and its estuary in Tanzania, and investigates their perceptions of the main threats to this system. Our findings reveal that all of the stakeholder groups place a high value on the provision of domestic water, habitat for wild plants and animals, tourism, and erosion control, and a relatively low value on the prevention of saltwater intrusion, refuge from predators, spiritual fulfillment, nonrecreational hunting, and the provision of traditional medications and inorganic materials for construction. Differences emerge, however, between the groups in the value assigned to the conservation of riverine and estuarine fauna and the provision of raw materials for building and handicrafts. Declining fish populations and an increasing human population are identified by the residents and conservation employees, respectively, as their prime concerns regarding the future conditions of the Wami River and its estuary. These groups also acknowledge increasing salinity levels and the loss of mangroves as other key concerns. The identification of these mutual interests and shared concerns can help build common ground among stakeholders while the recognition of potential tensions can assist managers in balancing and reconciling the multiple needs and values of these different groups.

Presento aquí un poema del humanista hispano-latino Juan de Verzosa. El texto fue enviado por el autor en 1555, junto con una carta, a Jerónimo Zurita, y se conserva actualmente en la Biblioteca de la Real Academia de la Historia de Madrid (Ms.9/112, fols.535-536). Aparentemente trata de un amigo del autor llamado Julio aficionado a la caza de aves. Pero la lectura del poema a la luz de las Epístolas de Verzosa permite entrever la intención última del autor e incluso quién fue el ‘cazador’ Julio aludido.

The origins of agriculture and the shift from hunting and gathering to committed agriculture is regarded as one of the major transitions in human history. Archeologists and anthropologists have invested significant efforts in explaining the origins of agriculture. A period of gathering intensification and experimentation and pursuing a mixed economic strategy seems the most plausible explanation for the transition to agriculture and provides an approach to study a process in which several nonlinear processes may have played a role. However, the mechanisms underlying the transition to full agriculture are not completely clear. This is partly due to the nature of the archeological record, which registers a practice only once it has become clearly established. Thus, points of transitions have limited visibility and the mechanisms involved in the process are difficult to untangle. The complexity of such transitions also implies that shifts can be distinctively different in particular environments and under varying historical and social conditions. In this paper we discuss some of the elements involved in the transition to food production within the framework of resilience theory. We propose a theoretical conceptual model in which the resilience of livelihood strategies lies at the intersection of three spheres: the environmental, economical, and social domains. Transitions occur when the rate of change, in one or more of these domains, is so elevated or its magnitude so large that the livelihood system is unable to bounce back to its original state. In this situation, the system moves to an alternative stable state, from one livelihood strategy to another.

A multi-sectorial regime of protection including international treaties, conservation and security measures, demand reduction campaigns and quasi-military interventions has been established to protect rhinos. Despite these efforts, the poaching of rhinos and trafficking of rhino horn continue unabated. This dissertation asks why the illegal market in rhinoceros horn is so resilient in spite of the myriad measures employed to disrupt it. A theoretical approach grounded in the sociology of markets is applied to explain the structure and functioning of the illegal market. The project follows flows of rhino horn from the source in southern Africa to illegal markets in Southeast Asia. The multi-sited ethnography included participant observations, interviews and focus groups with 416 informants during fourteen months of fieldwork. The sample comprised of, amongst others, convicted and active rhino poachers, smugglers and kingpins, private rhino breeders and hunting outfitters, African and Asian law enforcement officials, as well as affected local communities and Asian consumers. Court files, CITES trade data, archival materials, newspaper reports and social media posts were also analysed to supplement findings and to verify and triangulate data from interviews, focus groups and observations. Central to the analysis is the concept of “contested illegality”, a legitimization mechanism employed by market participants along the different segments of the horn supply chain. These actors' implicit or explicit contestation of the state-sponsored label of illegality serves as a legitimising and enabling mechanism, facilitating participation in gray or illegal markets for rhino horn. The research identified fluid interfaces between legal, illegal and gray markets, with recurring actors who have access to transnational trade structures, and who also possess market and product knowledge, as well as information about the regulatory regime and its loopholes. It is against the background of colonial, apartheid and neoliberal exploitation and marginalization of local communities that a second argument is introduced: the path dependency of conservation paradigms. Underpinning rhino conservation and regulation are archaic and elitist conservation regimes that discount the potential for harmonious relationships between local communities and wildlife. The increasing militarization of anti-poaching measures and green land grabs are exacerbating the rhino problem by alienating communities further from conservation areas and wild animals. The third argument looks at how actors deal with coordination problems in transnational illegal markets. Resolving the coordination problems of cooperation, value and competition are considered essential to the operation of formal markets. It is argued that the problem of security provides an additional and crucial obstacle to actors transacting in markets. The systematic analysis of flows between the researched sites of production, distribution and consumption of rhino horn shows that the social embeddedness of actors facilitates the flourishing of illegal markets in ways that escape an effective enforcement of CITES regulations.

L’utilisation de l’espace par une proie herbivore est souvent modulée par le compromis entre l’acquisition de fourrage et l’évitement de la prédation. Nous avons testé l’effet de la manipulation de la disponibilité de fourrage et du ratio couvert forestier/ouverture sur l’utilisation de l’espace par le cerf de Virginie (Odocoileus virginianus) et sa vulnérabilité à la chasse sportive sur l’île d’Anticosti. Nos résultats ont démontré que l’utilisation de l’espace par le cerf et sa vulnérabilité à la chasse peuvent être modifiées par différentes composantes structurales de l’habitat. L’augmentation de la disponibilité de fourrage a entrainé une plus grande utilisation des prairies fertilisées par le cerf, tandis que la diminution du ratio couvert forestier/ouverture a augmenté sa vulnérabilité à la chasse. Ces résultats procurent des pistes de solutions pour les gestionnaires fauniques qui doivent à la fois réduire les dommages causés par les hautes densités de cerfs et satisfaire les chasseurs en maintenant un nombre élevé d’observation de cerfs.
