Short And Long Term

Abstract Global average temperatures and sea water pCO2 have rapidly increased due to the oceanic uptake of atmospheric carbon dioxide producing severe consequences for a broad range of species. The impacts on marine ectotherms have been largely reported at short-term scales (i.e. from days to weeks); however, the prolonged effects on long-term processes such as reproduction have received little attention. The gastropod Ocenebra erinaceus is a key predator structuring communities on rocky shores of the French and UK coasts. Even though rocky shore species are regarded as being very tolerant to changes in temperature and pH, many of them are living near their upper tolerance limits, making them susceptible to rapid environmental changes. Here, we report that future mean sea water conditions (RCP8.5, + 3°C and ~ 900 µatm CO2) do not significantly affect the physiology and molecular response of O. erinaceus adults after 132 days. During the first fifty-days, there was a slight impact on oxygen consumption rates and body weight; however, after ninety-five days of exposure, gastropods relied on food resources to fully acclimate to the experimental condition. Despite this, it was after long-term exposure (~ 10 months) reproduction ceased in females exposed to these future sea water conditions. Therefore, in the short-term O. erinaceus appear to be capable of full compensation; however, in the long-term, they fail to invest in reproduction. Future research should take into account the combined results from both, short- and long-term effects to improve our projections of the ecological consequences of climate change.

AbstractGlobal average temperatures and seawater pCO2 have rapidly increased due to the oceanic uptake of atmospheric carbon dioxide producing severe consequences for a broad range of species. The impacts on marine ectotherms have been largely reported at short-term scales (i.e. from days to weeks); however, the prolonged effects on long-term processes such as reproduction have received little attention. The gastropod Ocenebra erinaceus is a key predator structuring communities on rocky shores of the French and UK coasts. Even though rocky shore species are regarded as being very tolerant to changes in temperature and pH, many of them are living near their upper tolerance limits, making them susceptible to rapid environmental changes. Here, we report that future mean seawater conditions (RCP8.5, + 3 °C and ~ 900 μatm CO2) do not significantly affect the physiology and molecular response of O. erinaceus adults after 132 days. During the first 50 days, there was a slight impact on oxygen consumption rates and body weight; however, after 95 days of exposure, gastropods fully acclimated to the experimental condition. Despite this, reproduction in females exposed to these future seawater conditions ceased after long-term exposure (~ 10 months). Therefore, in the short-term, O. erinaceus appear to be capable of full compensation; however, in the long-term, they fail to invest in reproduction. We conclude studies should be based on combined results from both short- and long-term effects, to present realistic projections of the ecological consequences of climate warming.

Imagery appears to be associated with higher levels of anxiety than does worry. Borkovec has argued that worry could be a way of avoiding distressing imagery and the associated affect. Thus worry could suppress emotional activation, interfere with emotional processing, and contribute to the maintenance of anxiety. This hypothesis suggests that short and long-term effects of worrying after experiencing a distressing stimulus should differ from the effects of engaging in imagery. In the short term, imagery should maintain anxiety while worry should not do so, or should do so less. In the longer term, worry should be a less successful way of reducing anxiety associated with the stimulus than imagery, and should be followed by a greater number of intrusive cognitions (indicating the relative failure of emotional processing). These predictions were tested by asking subjects to worry, engage in imagery or “settle down” after watching a distressing video. The results were broadly consistent with the hypothesis. Other interpretations are also considered.

Background and aim: Referring to the ecosocial theory and utilising the ‘natural experiment’ setting provided by the global recession at the beginning of 1990s, the aim of our study was to analyse the short- and long-term associations between trade and mental health in young students followed until mid-adulthood. Method: The study was based on two prospective cohort studies, the older and the younger Northern Swedish Cohort which both consisted of all pupils in a middle-sized industrial town in Northern Sweden. At age 21, the younger cohort entered the labour market during the deep recession of the early 1990s, while the older cohort entered the labour market during the boom of the 1980s. Both cohorts were followed up with a high response rate in mid adulthood. For this study, all students were selected at age 21. Results: At age 21, those who studied during recession had more depressive and functional somatic symptoms than those who studied during boom. The cohort differences did not remain over age: by the follow-up in early middle age the differences between the cohorts were non-significant, most notably due to decreased depressive symptoms in the younger cohort and increase of functional somatic symptoms in the older cohort. Conclusions: The short-term mental health consequences of the business cycle seem to be more extensive than limited only to those who are unemployed, even though the possible long-term consequences seem to be more complex. Thus, the macrolevel had a great short-term impact on the individual level in relation to the microlevel setting of university/school. The chronosystem was also of major importance. Future research would benefit from taking the context into account.

Short Term Effects

Ambient scents are being increasingly used in different service environments. While there is emerging research on the effects of scents, almost nothing is known about the long-term effects of consumers’ repeated exposure to ambient scents in a service environment as prior studies on ambient scents have been lab or field studies examining short-term effects of scent exposure only. Addressing this limitation, we examine the short- and long-term effects of ambient scents. Specifically, we present a conceptual framework for the short- and long-term effects of nonconsciously processed ambient scent in olfactory-rich servicescapes. We empirically test this framework with the help of two large-scale field experiments, conducted in collaboration with a major German railway company, in which consumers were exposed to a pleasant, nonconsciously processed scent. The first experiment demonstrates ambient scent’s positive short-term effects on consumers’ service perceptions. The second experiment—a longitudinal study conducted over a 4-month period—examines scent’s long-term effects on consumers’ reactions and demonstrates that the effects persist even when the scent has been removed from the servicescape.

The COVID-19 pandemic is having a massive impact on and may fundamentally change the pathways and trajectories of sustainable energy development. This article examines the impact of COVID-19 on Asia’s sustainable energy development and proposes agendas for future energy research in response to the pandemic. The review and research agendas are oriented towards achieving the Sustainable Development Goal 7 (SDG 7), ensuring access to affordable, reliable, sustainable and modern energy for all. The following three key questions need to be addressed by researchers: (1) In what ways does COVID-19 make sustainable energy development more important than ever? (2) What are the short- and long-term effects of COVID-19 on sustainable energy development? (3) How can responses to COVID-19 meet the objectives of sustainable energy development?

Economic development in a country is indicated by an increase in the number of industrial sectors and other supporting facilities such as transportation. However, there is another impact on developments industrial sectors and transportation, especially environmental degradation. Air pollution is one of the environmental degradation. This research was conducted to determine the short-term and long-term environmental impact of industry and transport in Indonesia. The data analysis method in this research used Autoregressive Distribution Lag (ARDL) to see the short-term and long-term effects between research variables. The data used are data on CO2 emissions, the amount of industries and transport in Indonesia from 1965 - 2018. The results showed that the industry had a negative impact on increasing CO2 emissions in the short and long term. Meanwhile, transportation has a positive impact in the short term and a negative impact in the long term.

Main Effects

Ecological succession in tropical savannas is limited by seasonal fire, which affects habitat quality. Although fire may cause negligible or positive effects on animals occupying savannas, most short-term studies (months to a few years) are based on a single temporal sampling snapshot, and long-term studies (decades) are rare. We sampled four lizard species in Amazonian savannas to test the effects of fire and vegetation cover on lizard densities at two temporal scales. In the short-term, we use three sampling snapshots to test the effects of fire and vegetation cover on estimated lizard densities over the subsequent 1–5 years. In the long-term, we test the effects of fire and changes in vegetation cover over 21 years on current lizard density differences. In the short-term, species responses were usually consistent with foraging and thermoregulation modes. However, the results were not consistent among species and years, although the variances in species density explained by year as a random factor were generally low. In the long-term, the main effects of fire and vegetation cover show that lizard densities may change spatially, but not necessarily temporarily. Wildfire is a natural resource of savannas and apparently have little impact on resident lizards of that ecosystem.

Published Research

Wildlife research often requires marking and tagging animals to collect data on survival, reproduction, movement, behaviour and physiology. Identification of individual marine mammals can be carried out using tags, brands, paint, dye, photogrammetry, telemetry and other techniques. An analysis of peer-reviewed articles published from January 1980 to April 2011 addressing the effects of marking revealed a preponderance of studies focussed on short-term effects such as injuries and behavioural changes. Some marking techniques were reported to cause pain and to change swimming and haul-out behaviour, maternal attendance, and duration of foraging trips. However, marking has typically not been found to affect survival. No published research has addressed other possible long-term effects of marking related to injuries or pain responses. Studies of the more immediate effects of marking (mostly related to externally attached devices such as radio-transmitters) have shown a variety of different types and magnitudes of responses. It is important to note that studies failing to find treament differences are less likely to be published, meaning that the present and any other reviews based on published literature may be a biased sample of all research conducted on the topic. Publishing results that found no or low impacts (i.e. best practices) as well as those that found significant impacts on animals should both be encouraged. Future research under more controlled conditions is required to document acute effects of marking, including injury and pain, and to better understand longer-term effects on health, reproduction and survival. We recommend that studies using marked animals standardise their reports, with added detail on methodology, monitoring and sampling design, and address practices used to minimise the impact of marking on marine mammals.

AbstractMaternal thyroid hormones (THs) are known to be crucial in embryonic development in humans, but their influence on other, especially wild, animals remains poorly understood. So far, the studies that experimentally investigated the consequences of maternal THs focused on short-term effects, while early organisational effects with long-term consequences, as shown for other prenatal hormones, could also be expected. In this study, we aimed at investigating both the short- and long-term effects of prenatal THs in a bird species, the Japanese quail Coturnix japonica. We experimentally elevated yolk TH content (the prohormone T4, and its active metabolite T3, as well as a combination of both hormones). We analysed hatching success, embryonic development, offspring growth and oxidative stress as well as their potential organisational effects on reproduction, moult, and oxidative stress in adulthood. We found that eggs injected with both hormones had a higher hatching success compared with control eggs, suggesting conversion of T4 into T3 by the embryo. We detected no other clear short-term or long-term effects of yolk THs. These results suggest that yolk thyroid hormones are important in the embryonic stage of precocial birds, but other short- and long-term consequences remain unclear. Research on maternal thyroid hormones will greatly benefit from studies investigating how embryos use and respond to this maternal signalling. Long-term studies on prenatal THs in other taxa in the wild are needed for a better understanding of this hormone-mediated maternal pathway.

Abstract The aim of the present study was to examine the short- and long-term effects of changes in vegetation structure caused by shrub removal and mowing on isopod diversity and composition in Natura 2000 habitats of Mátra Landscape Protection Area. Species richness and isopod diversity increased in the short term as a result of annual changes in vegetation; however, the values of both indices were reduced in the long term. The changes in vegetation structure on a regional scale led to a reduced isopod diversity in the short and long term. The changes in vegetation structure caused alterations in community structure in the long term. We conclude that changes of vegetation structure have a negative effect on species richness and the diversity of isopod communities in the long term.
