Recently, a growing number of studies have shown that the growth of organisms is not limited by only one resource at any one time. Co-limitation, i.e., the simultaneous limitation of an organism¿s growth by multiple resources, is an emerging topic in ecological research. As yet, theoretical concepts for co-limitation are mainly derived for primary producers (plants/algae). Several types of co-limitation, i.e., the way how organisms are co-limited, were proposed for plants and some of which can be probably applied to consumers as well. However, consumers differ fundamentally from plants in their various resource acquisition strategies, suggesting to the need for new co-limitation types. Additionally, the proposed co-limitation types for plants are inconsistently defined among studies. Therefore, a general framework is required in which the different types of co-limitation are clearly defined. The present project aims to develop a generally applicable theoretical framework for consumer co-limitation, in which the different types of co-limitation are clearly defined and explicitly described. The project will focus on herbivorous consumers as they are especially sensitive to constraints in resource quantity and quality. I will review existing theories in nutritional ecology and conduct a comprehensive literature survey on herbivore characteristics and food categories. This knowledge is essential to develop different types of co-limitation, which will be described (i) mathematically, (ii) graphically, (iii) with help of case studies, and linked to each other in a novel theoretical framework. This framework will improve the understanding of mechanisms behind consumer co-limitation and provide a basis for the development of hypotheses which can be tested empirically. Thus, the elaboration of the proposed framework is of crucial importance in the further development of research on co-limitation.

最近，越来越多的研究在任何时候都不受一种生物的限制。多种资源的增长是生态研究中的一个新兴话题。可能还适用于各种资源获取策略，这表明需要新的共同限制类型。框架的共限制，其中不同类型的共限制是对资源和质量的约束敏感的。 （ii）（ii）（iii）在案例研究的帮助下，在小说中相互联系。因此，对支撑框架的详细说明对于进一步的研究共同限制至关重要。
