“…Increased periods of warmer, wetter climate in the Midwest due to climate change may create conditions that increase winter survival of white‐tailed deer and increase transmission of meningeal worm, which could lead to further moose declines (Murray et al , Lankester , Pickles et al ). Because presence of the disease is tied to overlap between these 2 species, the increase in meningeal worm is likely to occur on the southern edge of moose range where they are already stressed by climate change (Feldman et al ).…”

Climate change is an increasing concern for wildlife managers across the United States and Canada. Because climate change may alter populations and harvest dynamics of key species in the region, midwestern states have identified the effects of climate change on ungulates as a priority research area. We conducted a literature review of projected climate change in the Midwest and the potential effects on whitetailed deer (Odocoileus virginianus) and moose (Alces alces). Warmer temperatures and decreasing snowpack in the region favor survival of white-tailed deer. In contrast, moose may become physiologically stressed in response to warming, and increasing deer populations spreading disease will exacerbate the problem. Although there is some uncertainty about exactly how the climate will change, and to what degree, robust projections suggest that deer populations will increase in response to climate change and moose populations will decrease. Managers can begin preparing for these changes by proactively creating management plans that take this into account. Ó

“…ENMs were based on a total of 160 occurrence records pertaining to the 5 species obtained from field studies and present-day bioclimatic, spatial heterogeneity and soil classification GIS data layers at 30 arc-seconds (~1 km) resolution. 19 bioclimatic variables along with altitude, slope and aspect data were obtained from the WorldClim database (Hijmans et al, 2005;www (Brown, 2014) and allowing maximum 0.8 correlation coefficient (Feldman et al, 2017). Accuracy of model predictions were evaluated using the area under the (receiver operating characteristic) curve (AUC) calculated in MAXENT (Yi et al, 2016;Fois et al, 2018 ).…”

Spatial heterogeneity was quantified using 14 metrics based on the Enhanced Vegetation Index (EVI) acquired by the Moderate Resolution Prior to analysis we performed a paired Pearson correlation test to remove highly correlated parameters allowing for a maximum correlation coefficient of 0.8(Feldman et al, 2017). To predict distribution of species at the Last Glacial Maximum (LGM) we projected models obtained from our present day species-bioclimatic analysis (dataset 2) onto the LGM using three general circulation models (CCSM4, MIROC-ESM, and MPI-ESM-P) available at WorldClim.…”

Despite its amazing biodiversity, the Eastern Mediterranean remains a highly understudied region especially when compared to the Western Mediterranean. Scarcity of such studies restrict our understanding of the processes shaping diversity across the entire Mediterranean. To this end we used a combination of molecular markers and presence/absence data from all species of the Eastern Mediterrranean genus Ricotia collected across its full geographic range to determine historical, ecological and evolutionary factors responsible for lineage-specific diversification in this genus. Network analysis based on nuclear ribosomal and chloroplast DNA revealed high genetic structure within all lineages and phylogenetic reconstructions based on the multispecies coalescent showed that within lineage diversification corresponded to the onset of the Mediterranean climate. Reconstruction of ancestral histories indicate the genus originated within Anatolia and slowly spread across the Eastern Mediterranean and Levant using the Taurus mountains. Ecological niche models based on climatic and environmental variables suggest local populations did not go through any major distributional shifts and have persisted in present day habitats since the LGM. Furthermore, niche differentiation tests revealed significant niche differences between closely related species and showed the main variables predicting species limits to be different for each species. Our results give crucial information on the patterns and processes shaping diversity in the Eastern Mediterranean and show the main factor promoting diversification to be local environmental dynamics and ecological specialization and not large scale latitudinal movements as often reported for southern Europe. By determining regional and global patterns of diversification in an eastern Mediterranean genus we further our understanding of the major trends influencing plant diversity in the Mediterranean basin as a whole.

“…Whatever the mode and cause of changes in distribution patterns, and indeed for interacting food webs, populations ought to adjust to biogeographic shifts through a suite of mechanisms including demographic patterns, physiological and phenotypic plastic adjustments as well as natural selection (Webster et al, 2016) with consequences on parasitism (Feldman et al, 2017). Two hypothetical scenarios may occur among agroecosystems.…”

Global Climate Change as a Driver of Bottom-Up and Top-Down Factors in Agricultural Landscapes and the Fate of Host-Parasitoid Interactions

The global climate is rapidly changing and the evidence is increasingly manifesting across various biological systems. For arthropods, several studies have demonstrated how changing climates affect their distribution through phenological and physiological responses, largely focusing on various organismal fitness parameters. However, the net-effect of the changing climate among ecological communities may be mediated by the feedback pathways among interacting trophic groups under environmental change. For agroecosystems, the maintenance of the integrity of trophic interactions even under climate variability is a high priority. This is even more important in this era where there is advocacy for sustainable agriculture, with higher emphasis on environmentally benign methods. For this reason, pest management in food production systems using biological control (especially use of parasitoid antagonists) has come to the forefront. In this review, we give an overview of the diversity of physiological responses among host insect and parasitoid populations and how this may influence their interactions. We highlight how climate change may modify bottom-up and top-down factors among agroecosystems with a particular focus on plant-insect host-parasitoid tritrophic interactions. We also outline how habitat management may influence arthropod population dynamics and how it can be manipulated to improve on-farm climate resilience and parasitoid conservation. We wrap-up by highlighting how the application of knowledge of conservation biodiversity, designing of multifunctional resilient landscapes, and evolutionary physiology of arthropods under thermal stress may be used to improve the fitness of mass-reared parasitoids (in or ex situ) for the improvement in efficacy of parasitoids ecosystem services under thermally stressful environments
