Visible implant elastomer (VIE) success in early larval stages of a tropical amphibian species

2020

AbstractAnimals are often difficult to distinguish at an individual level, but being able to identify individuals can be crucial in ecological or behavioral studies. In response to this challenge, biologists have developed a range of marking (tattoos, brands, toe-clips) and tagging (PIT, VIA, VIE) methods to identify individuals and cohorts. Animals with complex life cycles are notoriously hard to mark because of the distortion or loss of the tag across metamorphosis. In frogs, few studies have attempted larval tagging and none have been conducted on a tropical species. Here, we present the first successful account of VIE tagging in early larval stages (Gosner stage 25) of the dyeing poison…

The effect of an eco-label on the booking decisions of air passengers

2022

In the last few years there has been an increasing attempt to find solutions on how to mitigate the environmental impacts of air travel. Behavioral change has hereby been identified as the measure with the most significant impact. One way to encourage behavioral change is the use of eco-labels. Eco-labels have, to date, received scant attention in the aviation industry, and their effect on air travel behavior is still largely unknown. This study explores the effect of an eco-label on the booking decisions of passengers. We conduct a stated choice experiment with 553 air passengers. Our findings show that providing passengers with an eco-label leads to behavioral change, as the label makes t…

Exploring the potential of an air transport eco-label

2018

Air transport plays a vital role in tourism because it makes long-haul destinations accessible and more frequent vacations possible. Despite its benefits, air travel extensively contributes to climate change. Behavioural change is seen as a key driver in mitigating the environmental impacts of air transport. One way to encourage behavioural change is the use of eco-labels. This paper presents the idea of introducing an air transport eco-label. It explores the idea’s potential and realization through the thematic analysis of 12 interviews with airline industry experts. The results indicated a need for an air transport eco-label. It could help build awareness among air travellers by providing…

Utilising mark-recapture data for Bayesian modelling of fish mortality

2013

In this work, the aim was to produce a realistic assessment of yearly mortality of Archipelago Sea pike perch during the period 1997-2012. The utilized data origins from the mark-recapture experiment carried out by the Finnish Game and Fisheries Research Institute (FGFRI). In this mark-recapture experiment, returnings of the marks were based on voluntary tag reporting by the fishermen gaining small monetary rewards. In this study design, the count of returned tags is affected by the size of the release cohort, efficiency of the fishing method used by a fisherman and the fisherman’s willingness to return the tag. In addition, each year a proportion of the tags become detached from fish, whic…

An eco-label for the airline industry : instrument for behavioral change?

2017

Climate change is the biggest challenge humanity has ever faced and there is no doubt that human activities are the main cause. One activity that has received much attention in this discussion is air transportation. Although its contribution is still moderate, this industry is growing at a very fast rate and with that its impact on climate change. In order to enjoy its social and economic benefits also in the future and to avoid regulatory restrictions, the industry’s contribution needs to be kept in check. Various mitigation strategies exist such as technological, market-based, operational, regulatory and behavioral changes. This dissertation focuses on behavioral change. One instrument le…

Are habitat loss, predation risk and climate related to the drastic decline in a Siberian flying squirrel population? A 15 year study

2014

To devise effective conservation actions, it is important to know which factors are associated with the population parameters of a declining population. Using mark–recapture methods, we estimated the annual population size, growth rate and survival probability of an ear-tagged flying squirrel population over a 15-year period in a 4,500 ha study area in western Finland. The species is considered vulnerable, but detailed knowledge concerning population sizes or trends is lacking. The population parameters and changes therein were regressed against habitat availability, an indicator of predation pressure, and mean winter temperature (an indicator of climate change), to reveal potential reasons…

Practices and perceptions on ecolabels of Finnish companies with circular economy business models

2022

There is a need to better understand the role of ecolabels in the scope of the Circular Economy transition. The aim of this research was to study the perspectives and practices of ecolabel use among Finnish companies with circular economy business models. The survey-based research targeting 214 companies (response rate 18% = n. 39) showed that ecolabels were not commonly used among the sample of companies. (Human) resource constraints were found in this research to partially explain the low uptake of ecolabels. Therefore, the research opens further questions as to alternative benchmarking and communication tools for the environmental performance of companies that see themselves as frontrunn…
