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 …
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…
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…
Data from: Gene flow from an adaptively divergent source causes rescue through genetic and demographic factors in two wild populations of Trinidadian…
2015
Genetic rescue, an increase in population growth owing to the infusion of new alleles, can aid the persistence of small populations, but its use as a management tool is limited by a lack of empirical data geared towards predicting effects of gene flow on local adaptation and demography. Experimental translocations provide an ideal opportunity to monitor the demographic consequences of gene flow. In this study we take advantage of two experimental introductions of Trinidadian guppies to test the effects of gene flow on downstream native populations. We individually marked guppies from the native populations to monitor population dynamics for 3 months before and 26 months after gene flow. We …
Modeling the epidemiological history of plague in Central Asia: Palaeoclimatic forcing on a disease system over the past millennium
2010
Abstract Background Human cases of plague (Yersinia pestis) infection originate, ultimately, in the bacterium's wildlife host populations. The epidemiological dynamics of the wildlife reservoir therefore determine the abundance, distribution and evolution of the pathogen, which in turn shape the frequency, distribution and virulence of human cases. Earlier studies have shown clear evidence of climatic forcing on contemporary plague abundance in rodents and humans. Results We find that high-resolution palaeoclimatic indices correlate with plague prevalence and population density in a major plague host species, the great gerbil (Rhombomys opimus), over 1949-1995. Climate-driven models trained…
Conceptualizing nature-based science tourism: a case study of Seili Island, Finland
2021
Nature-based tourism has been widely addressed, yet research on nature-based science tourism, founded on science, scientific knowledge, and/or engagement in scientific research, is still scarce. Drawing on tourist motivation, nature-based tourism, special interest tourism, and science tourism, a novel theoretical conceptualization of nature-based science tourism was developed. The framework identified three categories of science tourism with intensifying levels of tourists’ interest in scientific knowledge and tourist engagement: tourism based on scientific knowledge, tourism with scientific adventure or volunteering, and scientific research tourism. In the empirical part, the framework was…
Global epidemiology of coronavirus disease 2019 and lessons for effective control of this and future pandemics
2021
Barely 1 year after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was first reported in China, the virus has infected approximately 120 million people, caused around 3 million deaths, and adversely affected the global economy Despite stringent measures to flatten the epidemiologic curve of the pandemic, there have been spikes and waves of the infection in many countries, particularly in the American, European, and Asian continents This review critically evaluated the global epidemiology of the novel coronavirus disease 2019 (COVID-19) to provide advice on other possible ways of managing the disease as various COVID-19 vaccines are being rolled out To effectively control this …
Pasaules Dabas fonda (World Wildlife Fund) sociālo reklāmas kampaņu vizuālo statisko reklāmu semiotiskā un auditorijas analīze (2010-2014)
2016
Bakalaura darba „„Pasaules Dabas fonda” (World Wildlife Fund) sociālo reklāmas kampaņu vizuālo statisko reklāmu semiotiskā un auditorijas analīze (2010 – 2014)” ietvaros tiek pētītas semiotiskās iezīmes šīs organizācijas reklāmās, kā arī auditorijas attieksme pret tām. Darba pētījuma mērķis – noskaidrot reklāmu vēstījumu ietekmējošos semiotiskos faktorus. Darbā ir apskatītas teorijas par sociālo mārketingu, reklāmu, vizuālo komunikāciju. Empīriskajā daļā ir veikta kontentanalīze un semiotiskā analīze par 88 vizuālajām statiskajām reklāmām, kā arī auditorijas aptauja. Rezultātā sniegtas atbildes uz pētnieciskajiem jautājumiem un izdarīti secinājumi par pētījuma rezultātiem.
