    Author : Rebecka Relfsson; [2023-08-18]
    Keywords : African savanna elephant; elephant highways; interspecies interactions; predation avoidance; predator-prey interaction; temporal activity;

    Abstract : African savanna elephants (Loxondonta africana) are the world’s largest land-mammal and are considered a keystone species. The effect they have on vegetation and their environment is well known, but their effect on other animal species is less studied. READ MORE

  3. 2. Is sugar as sweet to the palate asseeds are appetizing to the belly? : Taste responsiveness to seven sweet-tastingsubstances in white-faced sakis (Pithecia pithecia)

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Mikel Redin Hurtado; [2023]
    Keywords : Food-associated carbohydrates; relative sweetness; seed predation; steviol glycosides; taste preference thresholds; taste responsiveness; white-faced sakis;

    Abstract : Differences in taste perception between species are thought to reflect evolutionaryadaptations to dietary specializations such as seed predation. By employing a two-bottlepreference test, the purpose of the current study was to evaluate the taste responsiveness forfive food-associated carbohydrates and two steviol glycosides in four adult white-faced sakis(Pithecia pithecia).

    Keywords : trace fossils; ichnology; Cambrian; Daedalus desglandi; Alectorurus circinatus; Syringomorpha nilssoni; the agronomic revolution;

    Abstract : The Cambrian explosion not only shaped the ecosystems of the Phanerozoic, but fundamentally changed how biota interacts with the environment, including the substrate. Cambrian trace fossils Alectorurus and Syringomorpha as well as Ordovician-Silurian Daedalus represent novel modes of faunal interaction with the newly innovated shallow marine mixed-ground and have surprisingly limited stratigraphic ranges.
