Накратко на български

Енергийният баланс на мигриращите певчести птици се изследва чрез специални сензори, които следят физиологията им по време на полет. Това помага да се разбере как околната среда влияе върху разпределението на биоразнообразието при климатични промени.

The true cost of migration: testing the species-energy hypothesis by quantifying the energy budget of free flying avian migrants under spatially explicit environmental conditions

The annual long-distance migration of birds is a widespread phenomenon that underpins the seasonal distribution of biodiversity and ecological processes on Earth. However, knowledge of the energetic balance of animals undertaking these endurance flights and the drivers of this fascinating behavior undertaken by billions of individuals remains lacking. The TesSEH project aimed to quantify the demographic, spatial and temporal specific energetic budget of migratory songbirds by utilizing technological advances in biologging to determine fundamental physiological processes in the natural environment. By doing so, the TesSEHproject aimed to answer some of the fundamental questions in Ecology – how do patterns of large-scale seasonal movement evolve and which environmental drivers underlie this phenomenon. An understanding of the relationship between the environment and distribution of life on earth has impact on our understanding of how the planet and biodiversity may look under predicted climate and anthropogenic change, the processes that has led to the diversification on behavioral traits were recognize today. Overall, the TesSEH project delivered a robust package of novel data, developed modelling pipelines and analytical tools to finalise the goals of the fellowship and open up new avenues of research.

Цел на проекта

Migration is a key life-history stage for many avian species and underpins the distribution of biodiversity on Earth. The species-energy hypothesis states that energetics underlies spatial- and temporally-specific patterns; yet the energetic balance for free-flying migratory species is poorly understood due to the inherent difficulties in studying individuals across vast geographic scales. To date, it has not been possible to obtain a field-derived metric of energetics in passerines let alone relate it to the environmental energetic conditions experienced. Major advances at the MPI-AB in the miniaturisation of heart-rate loggers, and the launch of ICARUS tracking technology with high spatio-temporal resolution, will now enable unique insights into energetically costly flight behaviour over the full annual cycle. By filling a technological and a conceptual gap, the ER will be the first to develop a novel, integrated approach to quantify the true energetic costs in the natural environment across a continuum of flight strategies, and calibrate metabolic costs under controlled settings to transform the research field of energetics. Empirically-derived data, resulting from this action, will be used to test if the species-energy relationship is applicable to the vast majority of small songbirds which change their distribution in response to seasonal variation in conditions and resources. Furthermore, this will enable the development of a tool to refine flight performance models and determine the response of this biological system to climate change. It will permit explicit testing of the species-energy relationship under seasonally specific environmental conditions, with a unique approach of incorporating energetic demands into the system. Cumulatively, fulfilling the objectives of TesSSEH, will significantly contribute to biogeographic theory, develop our understanding of energetically efficient physiological traits and revolutionise avian energetic models.
