Í þessari grein er fjallað um lýðfræði sem undirgrein félagsfræðinnar í alþjóðlegu vísindastarfi. Fjallað er um helstu svið innan lýðfræðinnar, breytingar á mannfjölda á Íslandi síðustu áratugi og rannsóknir sem íslenskir fræðimenn hafa gert til aukins ...

Few studies have been able to directly measure the seasonal survival rates of migratory species or determine how variable the timing of migration is within individuals and across populations over multiple years. As such, it remains unclear how likely ...

For many migratory species, migration can represent a significant part of the annual cycle and the strategies used to move between the breeding and non-breeding areas vary considerably. Weather conditions are important during migration, particularly ...

Evolutionary theories of seasonal migration generally assume that the costs of longer migrations are balanced by benefits at the non-breeding destinations. We tested, and rejected, the null hypothesis of equal survival and timing of spring migration ...

The migrant black-tailed godwit (Limosa limosa) traditionally used natural wetlands in the Iberian Peninsula to prepare for migratory flights by feeding mainly in estuaries. In recent decades, this species has become increasingly dependent on rice ...

Iceland has increasingly been tangled in a dense network of various mobilities, leading to the growing transnational character of Icelandic society. This means that Iceland is involved in and affected by different forms of exchange and flows of ideas, ...

The Purple Sandpiper (Calidris maritima) is a medium-sized shorebird that breeds in the Arctic and winters along northern Atlantic coastlines. Migration routes and affiliations between breeding grounds and wintering grounds are incompletely understood. ...

The cyclically-repeated song of the male humpback whale (Megaptera novaeangliae) is an important social display on their breeding grounds, functioning in male-male interactions and/or as a reproductive display to attract females. The songs are gradually ...

In migratory birds, early arrival on breeding sites is typically associated with greater breeding success, but the mechanisms driving these benefits are rarely known. One mechanism through which greater breeding success among early arrivers can potentially ...

Migration has become a key issue in the contemporary European context, with depictions of Europe as under ‘attack’ due to the mass movement of uprooted populations, especially from Africa and the Middle East. The current sentiment of Europe in crisis ...
