[font=Times New Roman]Wenn schon, dann sollte man ein Zitat korrekt wiedergeben, und auch sonst sollte man sich doch an die Recht- und Groß- und Kleinschreibregeln des Forums und unserer Muttersprache halten. Gerade mit Blick auf Schüler sollte eine Lehrperson da doch eher pingelig sein, statt den Sprachzerfall auch noch öffentlich zu unterstützen, ODER?[/font]
[font=Times New Roman]Hier ist das korrekte Zitat und das Abstract aus dem Kongressband:[/font]

[font=Times New Roman](Es geht um eine nachtaktive Camponotus-Art. Tagsüber bleiben die Arbeiterinnen im Nest, verhalten sich photonegativ. Kranke und sterbende Ameisen jedoch vermeiden in den letzten Lebenstagen nicht mehr das helle Licht und werden photopositiv. Im Wahlversuch zwischen einem verdunkelten und einem beleuchteten Reagenzglas, die durch einen engen Durchgang verbunden sind, verhalten sie sich photopositiv. – Merkur)[/font]

[font=Times New Roman]A growing number of studies devoted to factors involved in the mediation of behaviour of social insects reports behavioural modifications induced in response to shortened life expectancy. These modifications include increased probability of switching to extranidal activities and of participation in risky tasks.[/font]
[font=Times New Roman]Moribund, wounded and infected individuals are also known to leave their nests to die in isolation. We will report a short review of these recent findings including our own data demonstrating that workers of a nocturnal ant species Campontus melanocnemis show increased photopositivity during the last few days preceding their death. Minor workers of C. melanocnemis were reared in controlled illumination conditions from the stage of an egg. Their illumination preferences were then tested by housing small groups of[/font]
[font=Times New Roman]individually marked ants in H-shaped dark-light choice nests consisting of two test tubes equipped with water reservoirs and connected by a narrow passage. One of the tubes was kept in darkness and the second one was exposed either to 12:12 LD or to constant white light. The ants which survived until the end of the experiment (during 40 or 80 days) were as a rule photonegative, but moribund workers showed increased photopositivity during the last few days preceding their death. Their photopositivity was not related simply to their inability[/font]
[font=Times New Roman]to leave the illuminated zone, as it was observed also in the subset of moribund workers which remained active during the last two days of their life. We also compared the survivorship of ants kept in constant darkness and at 12:12 LD. Exposure to illumination did not lead to increased ant mortality, which implies that increased photopositivity of moribund C. melanocnemis was the effect of physiological changes preceding their death, and not the cause of their mortality. Our findings provide thus an important cue concerning[/font]
[font=Times New Roman]proximate causal factors underlying behavioural modifications observed in moribund ants. [/font]
