Abstract: | Traditionally, evolutionary ecology and conservation biology have primarily been concerned with how environmental changes
affect population size and genetic diversity. Recently, however, there has been a growing realization that phenotypic plasticity
can have important consequences for the probability of population persistence, population growth, and evolution during rapid
environmental change. Habitat fragmentation due to human activities is dramatically changing the ecological conditions of
life for many organisms. In this review, we use examples from the literature to demonstrate that habitat fragmentation has
important consequences on oviposition site selection in insects, with carryover effects on offspring survival and, therefore,
population dynamics. We argue that plasticity in oviposition site selection and maternal effects on offspring phenotypes may
be an important, yet underexplored, mechanism by which environmental conditions have consequences across generations. Without
considering the impact of habitat fragmentation on oviposition site selection, it will be difficult to assess the effect of
fragmentation on offspring fitness, and ultimately to understand the impact of anthropogenic-induced environmental change
on population viability. |
