Zusammenfassung

Nachdem wir in den vorangegangenen Kapiteln den Begriff der intraspezifischen Konkurrenz eingeführt haben, kann man sich leicht vorstellen, was mit interspezifischer Konkurrenz (zwischenartlicher Konkurrenz; engl. interspecific competition) gemeint ist: Infolge der Ausnutzung von Ressourcen oder der Interferenz durch eine andere Art leiden die Individuen einer Spezies unter verringerter Fruchtbarkeit, geringerer Überlebenswahrscheinlichkeit oder eingeschränktem Wachstum. Diese individuellen Einflüsse wirken sich mit ziemlicher Wahrscheinlichkeit auf die Populationsdynamik und die Verbreitung der konkurrierenden Arten aus. Diese wiederum beeinflussen die Zusammensetzung der Lebensgemeinschaften, denen sie angehören. Aber diese individuellen Effekte wirken auch auf die Evolution dieser Arten, die selbst wieder die Verbreitung und Populationsdynamik der Spezies beeinflussen kann.
