Specialized Diet

Diet specialization has important consequences for how individuals or species deal with environmental change that causes changes in availability of prey species. We took advantage of a “natural experiment” — establishment of a commercial insect farm — that introduced a novel prey item, black soldier flies (Hermetia illucens (Linnaeus, 1758)), to the diet-specialist European Starling (Sturnus vulgaris Linnaeus, 1758). We investigated evidence for individual diet specialization (IDS) and the consequences of diet specialization and exploitation of novel prey on breeding productivity. In all 4 years of our study, tipulid larvae were the most common prey item. Soldier flies were not recorded in diets in 2013–2014; however, coincident with the establishment of the commercial insect farming operation, they comprised 22% and 30% of all prey items in the diets of European Starling females and males, respectively, in 2015. There was marked individual variation in use of soldier flies (4%–48% and 2%–70% in females and males, respectively), but we found little evidence of dichotomous IDS, i.e., where only some individuals have a specialized diet. We found no evidence for negative effects of use of soldier flies on breeding productivity: brood size at fledging and chick quality (mass, tarsus length) were independent of the number and proportion (%) of soldier flies returned to the nest.

Abstract The objectives of this study were to describe the diets of freshwater drum Aplodinotus grunniens in the Wabash River in the Midwestern United States. We used a multivariate ordination approach (nonmetric multidimensional scaling) to describe drum diets combined with a generalized linear model to test for covariation of diet with body size, sex, and longitudinal river gradient. Hydropsychidae (trichoptera, caddisfly larvae), pleuroceridae (gastropoda), and heptageniidae (ephemeroptera, mayfly larvae) were the most consumed prey items (∼75% of overall diets). Among all freshwater drum, hydropsychidae, pleuroceridae, and heptageniidae were present in 69%, 23%, and 38% of stomachs, respectively. Freshwater drum diets were similar along an upstream–downstream river gradient spanning 350 river km, but varied with body size and sex. Small- and medium-sized fish tended to consume more diptera and annelids compared with the largest individuals, which fed on mollusks and crayfish. With control for body size, the diets of male individuals were composed of more diptera (chironomidae) and annelid prey items compared with female individuals, whose diets included more molluscs and crayfish. Overall, we interpret the lack of diet diversity in freshwater drum with Wabash River longitudinal gradient as evidence of diet specialization. Alternatively, we propose that a potential dietary–river-gradient signal may be diluted as a function of increased freshwater drum longitudinal movements.

The Impact

Human-induced biodiversity loss has been accelerating since the industrial revolution. The climate change impacts will severely alter the biodiversity and biogeographical patterns at all scales, leading to biotic homogenization. Due to underfunding, a climate smart, conservation-prioritization scheme is needed to optimize species protection. Spatial phylogenetics enable the identification of endemism centers and provide valuable insights regarding the eco-evolutionary and conservation value, as well as the biogeographical origin of a given area. Many studies exist regarding the conservation prioritization of mainland areas, yet none has assessed how climate change might alter the biodiversity and biogeographical patterns of an island biodiversity hotspot. Thus, we conducted a phylogenetically informed, conservation prioritization study dealing with the effects of climate change on Crete’s plant diversity and biogeographical patterns. Using several macroecological analyses, we identified the current and future endemism centers and assessed the impact of climate change on the biogeographical patterns in Crete. The highlands of Cretan mountains have served as both diversity cradles and museums, due to their stable climate and high topographical heterogeneity, providing important ecosystem services. Historical processes seem to have driven diversification and endemic species distribution in Crete. Due to the changing climate and the subsequent biotic homogenization, Crete’s unique bioregionalization, which strongly reminiscent the spatial configuration of the Pliocene/Pleistocene Cretan paleo-islands, will drastically change. The emergence of the ‘Anthropocene’ era calls for the prioritization of biodiversity-rich areas, serving as mixed-endemism centers, with high overlaps among protected areas and climatic refugia.
