Identifying potential areas of expansion for the endangered brown bear (Ursus arctos) population in the cantabrian mountains (NW Spain)
2019
Many large carnivore populations are expanding into human-modified landscapes and the subsequent increase in coexistence between humans and large carnivores may intensify various types of conflicts. A proactive management approach is critical to successful mitigation of such conflicts. The Cantabrian Mountains in Northern Spain are home to the last remaining native brown bear (Ursus arctos) population of the Iberian Peninsula, which is also amongst the most severely threatened European populations, with an important core group residing in the province of Asturias. There are indications that this small population is demographically expanding its range. The identification of the potential are…
Mechanisms of population declines in boreal forest grouse
2007
Gilbert Ludwig tutki väitöskirjassaan, miksi kanalinnut ovat vähentyneet talousmetsissä. Suomen metsäkanalintukannat ovat vähentyneet merkittävästi viimeisen 40 vuoden ajan. Pesiin ja poikasiin kohdistuvaa saalistusta on pidetty tärkeimpänä syynä kanalintukantojen laskuun. Hakkuiden ja nuorten metsien osuuden lisääntymisen on katsottu lisänneen myyräkantoja ja niitä syöviä petoja, kuten kettuja, lisäten näin myös kanalintujen pesiin ja poikasiin kohdistuvaa saalistusta. Vuosikymmenten aikana laskenut poikastuotto on keskeisessä roolissa kanalintukantojen laskussa. - Ainakaan teerellä vuotuinen aikuiskuolleisuus ei ole lainkaan lisääntynyt. Hengissäsäilyminen on päinvastoin jopa parantunut, …
Neanderthal and carnivore activities at Llonin Cave, Asturias, northern Iberian Peninsula: Faunal study of Mousterian levels (MIS 3)
2018
Abstract This paper presents a study of the macromammalian fauna recovered from Mousterian levels of Llonin Cave. The sample is highly heterogeneous and comprises six species of ungulates, including Rupicapra pyrenaica, Capra pyrenaica, and Cervus elaphus, and seven species of carnivores, predominantly Ursus spelaeus, Crocuta spelaea, Canis/Cuon and Panthera pardus. The archaeozoological and taphonomic study of the remains shows preferential use of basal levels of the cave as a den for hyenas and leopards. Neanderthals were also present during this phase and they would have acted mainly on deer and some caprines, while the action of hyenas would mainly have been linked to scavenging of elem…
Seroprevalence of Norovirus Genogroup IV Antibodies among Humans, Italy, 2010–2011
2014
Antibodies specific to genogroup IV identified in human specimens suggest zoonotic exposure.
Diet, authoritarianism, social dominance orientation, and predisposition to prejudice
2015
Purpose – The purpose of the paper is to examine whether reported food habits (vegan, vegetarian, or carnivore diet) are associated with right-wing authoritarianism, prejudices against minorities and acceptance of social dominance. Design/methodology/approach – In total, 1,381 individuals completed validated questionnaires on dietary habits and attitudes. Associations were analysed using analyses of covariance on attitudes, adjusted for age with gender and diet as factors. Findings – Of the respondents, 35 per cent reported eating mixed food (including meat and fish), 31 per cent vegetarian food (excluding meat and fish) and 34 per cent vegan food (excluding animal products entirely). Auth…
Using the centre-periphery framework to explore human-carnivore relations
2023
Unidad de excelencia María de Maeztu CEX2019-000940-M Living alongside carnivores can incur both costs and benefits on people's lifeways. While positive outcomes of carnivore presence can foster coexistence, negative relations with carnivores can trigger carnivores' killing and undermine their conservation. In response to this, conservation efforts increasingly focus on promoting positive human-carnivore relations, most often through improvements in the flow of economic benefits from carnivores to local communities. However, there is a question mark over the effectiveness and potential consequences of market-based instruments for carnivore conservation. To understand the opportunities and p…
Occupancy, density, and activity patterns of a Critically Endangered leopard population on the Kawthoolei‐Thailand border
2023
Large carnivores have been largely extirpated from Southeast Asia due to deforestation, habitat fragmentation, and poaching. Estimating the density of endangered carnivore populations, and identifying relationships between species occupancy and both environmental and anthropogenic factors, is essential for effective conservation planning. Recently, the IUCN conservation status of the Indochinese leopard (Panthera pardus delacouri) was upgraded to "Critically Endangered. " We surveyed Kweekoh Wildlife Sanctuary in Kawthoolei, an area administered by the Karen ethnic group in eastern Myanmar, to quantify (1) leopard population density using spatially explicit mark-resight (SMR) models, (2) le…
Correlation of carnassial tooth size and body weight in recent carnivores (mammalia)
1988
The correlation between the lower carnassial crown area and the body weight is examined for modern carnivores. It is very high, but the ursids and felids show a relationship different from the other carnivore families. Some exceptions are discussed. The possibility of predicting body weight for fossils is given.
Oxygen isotope composition of North American bobcat (Lynx rufus) and puma (Puma concolor) bone phosphate: implications for provenance and climate rec…
2015
Feline carnivores are threatened by illegal wildlife trade. Tracing the provenance of unknown felid tissues via stable isotope analysis could provide important information in wildlife crime investigations. The oxygen isotope composition of mammalian skeletal phosphate (δ(18)Op) is widely applied to trace the origin of animal remains and to reconstruct migratory patterns in palaeontological, archaeological, ecological and wildlife forensic applications. Teeth and bones of terrestrial mammals form at constant body temperature in isotope equilibrium with body water, which is predominantly controlled by ingested meteoric water (δ(18)Ow) that varies systematically with latitude, altitude and cli…
Environment and subsistence strategies at La Viña rock shelter and Llonin cave (Asturias, Spain) during MIS3
2020
The sites of La Viña and Llonin have an important archaeological sequence corresponding to Marine Isotope Stage 3: Mousterian, Aurignacian and Gravettian periods. La Viña is a complex rock shelter with continuous occupations, being some (basically the Mousterian and the Aurignacian in contact levels) altered by post-depositional processes as a consequence of the irregular bedrock morphology and the type of processes involved. The cave of Llonin mainly consists of occasional human/carnivores occupations during the Mousterian and the Gravettian. The current multidisciplinary research has allowed us to obtain and match several preliminary data: site formation processes, fauna and stable isotop…
