Habitat preference of endangered Eastern Iberian Reed BuntingsEmberiza schoeniclus witherbyi
2011
Capsule Careful management is required to maintain or create habitats with the correct proportions of rush with reeds that are preferred by this subspecies. Aims To determine the habitat requirements of Eastern Iberian (Western Iberian Reed Buntings were not included in the study) Reed Buntings Emberiza schoeniclus witherbyi, a subspecies endemic to a few marshes in France, Spain and Morocco, with a population of 254–360 breeding pairs. Methods Twenty-five wetlands in Spain were surveyed and presence/absence of Iberian Reed Buntings was deteremined together with data on 41 environmental variables. The relationships between the birds and habitat data were investigated using glm. Results Prop…
Density Decline in a Mediterranean Seahorse Population: Natural Fluctuations or New Emerging Threats?
2021
Illegal wildlife trade is considered one of the most serious threats to biodiversity worldwide, along with habitat loss/degradation and overfishing of wild stocks. Seahorses are considered at high risk as these fish represent an important component of traditional Chinese medicine but are also sold as curios and ornamental fish. On a worldwide level, illegal trade is controlled by numerous laws and regulations, but it seems to continue by assuming more dynamic routes. In the Mediterranean Sea, Hippocampus guttulatus formed one of the largest populations at Mar Piccolo di Taranto in South-Eastern Italy. During the routine monitoring of this population in 2016, a dramatic density decrease was …
Role of the nNOS gene in ethanol-induced conditioned place preference in mice
2009
Nitric oxide (NO) produced by neuronal nitric oxide synthase (nNOS) has a role in synaptic plasticity, and evidence suggests its role in a range of effects produced by alcohol in the central nervous system. The aim of the current study was to investigate the role of the nNOS gene in the development of ethanol-induced conditioned place preference (CPP) in mice. The CPP paradigm is designed to investigate the reinforcing properties of drugs of abuse and the development of maladaptive behaviors, such as conditioned response to drug-associated stimuli, following repeated drug exposure. Adult male and female wild type (WT) and nNOS knockout (KO) mice on a mixed B6; 129S genetic background were t…
Interpretation of gut microbiota data in the ‘eye of the beholder’: A commentary and re‐evaluation of data from ‘Impacts of radiation exposure on the…
2021
1.Evidence that exposure to environmental pollutants can alter the gut microbiota composition of wildlife includes studies of rodents exposed to radionuclides. 2.Antwis et al. (2021) used amplicon sequencing to characterise the gut microbiota of four species of rodent (Myodes glareolus, Apodemus agrarius, A. flavicollis and A. sylvaticus) inhabiting the Chernobyl Exclusion Zone (CEZ) to examine possible changes in gut bacteria (microbiota) and gut fungi (mycobiota) associated with exposure to radionuclides and whether the sample type (from caecum or faeces) affected the analysis. 3.The conclusions derived from the analyses of gut mycobiota are based on data that represent a mixture of inges…
Cities and their effects on free-living and host-associated microbes
2023
Mikrobit ovat oleellisen tärkeitä elämälle maapallolla, ja niitä esiintyy vapaina ympäristössä tai isäntäorganismeissa tukien ekosysteemien ja/tai isäntien normaalia toimintaa. Ihminen vaikuttaa lähes kaikkiin planeettamme elinympäristöihin aiheuttaen niiden häviämistä ja huonontumista (mukaan lukien kaupunkien rakentaminen) sekä ympäristöjen saastumista ja ilmastonmuutosta. Mikrobiyhteisöjen (kutsutaan myös mikrobiotaksi, mukaan lukien bakteerit ja sienet) odotetaan reagoivan näihin ihmisen aiheuttamiin valintapaineisiin sopeutumalla muuttuvaan ympäristöön. Siten ihmisen aiheuttamat muutokset ympäristössä voivat muovata mikrobiyhteisöjä (sekä vapaasti eläviä että isäntiin liittyviä) muutta…
Hahmojen välisiä suhteita : interfiguraalisuus Donna Tarttin romaanissa The Secret History
2017
Tutkielma käsittelee interfiguraalisuutta – intertekstuaalisuuden alalajia, joka viittaa eri teksteissä esiintyvien henkilöhahmojen välisiin suhteisiin – Donna Tarttin romaanissa The Secret History. Tarttin romaanin päähenkilöitä tarkastellaan suhteessa neljän muun romaanin henkilöhahmoihin (F. Scott Fitzgeraldin The Great Gatsby, William Goldingin Lord of the Flies, Evelyn Waugh’n Brideshead Revisited sekä Oscar Wilden The Picture of Dorian Gray). Tutkielmassa eri teksteissä esiintyvien henkilöhahmojen välisiä interfiguraalisia kytköksiä peilataan suhteessa The Secret Historyn kertojan luotettavuuteen ja romaanin keskeisiin teemoihin. Tutkimusongelmana on, millaista potentiaalia interfigur…
Compound climate extreme events threaten migratory birds’ conservation in western U.S.
2022
In a warming world, more intense and frequent compound climate extreme events pose serious challenges to biodiversity and conservation on Earth as one of the 2030 United Nations’ sustainable development goals (SDGs): “Life On Land” (SDG 15). In summer 2020, concurrent swelling wildfires and a sudden cold snap in the western U.S. killed a massive number of migratory birds. In August 2020, the hot and humid weather in response to the wildfire radiation and the oceanic evaporation could result in killing heat stress for migratory birds along the coastal shoreline, particularly in California. The heat and smoke of wildfires forced the migratory birds to abandon such feeding grounds towards inla…

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…
Assessing tolerance for wildlife: human-elephant conflict in Chimanimani, Mozambique
2020
Human–elephant conflict (HEC) is a common problem for rural populations in sub-Saharan Africa. Recent studies have shown that willingness to tolerate wildlife is largely a function of perceived risks and benefits, but most technical assessments are limited to the immediate cause of the conflict and neglect the broader socioeconomic and political contexts. Based on two sets of interviews, this article provides a socioeconomic analysis of HEC in the buffer zone of Chimanimani National Reserve in Mozambique. Although traditional methods to scare off elephants were found to have little effect, a beehive fence introduced in 2016 initially appeared to be successful. However, follow-up three years…
