“…During summer, the availability of vegetative biomass is at its peak and there is an abundance of forage available to deer across the landscape. When there are multiple foraging options available, generalist herbivores such as deer should be able to selectively forage across the landscape and select food items that are the most nutritiously bene cial (Stephens and Krebs 1986;Sauvé and Côté 2007;Dykes et al 2020). During autumn, green biomass begins to senesce and deer are expected to opportunistically select patches that still contain high-quality forage; however, as patch quality depletes over time deer will become less selective (Dostaler et al 2011).…”

“…])(Johnson et al 1987;Ellis-Felege et al 2013). Cultivated forage species such as these generally have a high crude protein content and can provide wildlife high-quality foraging opportunities(Johnson et al 1987;Dykes et al 2020). Additionally, many cultivated forage species associated with meadows are grasses and therefore possess little to no plant secondary metabolites such as tannins or polyphenols to defend against herbivory (Orians and Ward 2010;Ward et al 2020).…”

White-tailed deer (Odocoileus virginianus) populations persist at densities higher than historical estimates throughout much of their North American range. In forest ecosystems, heavy browsing by high-density deer populations can suppress the growth and regeneration of woody plants and promote the establishment and growth of non-preferred forage items, such as grasses and ferns. Additionally, as forests are altered by anthropogenic development, grasslands and meadows are becoming increasingly common in forest landscapes where deer occur. We used activity densities to measure the seasonal patch preference of white-tailed deer between forest patches and anthropogenically-introduced meadows in northeast Ohio, a region with high-density deer populations. We also quantified the plant communities that were present in each patch type to identify forage plants that were available to deer. We found that deer preferred meadow patches and avoided forests during spring and summer. Meadow patches primarily consisted of non-native forage plants that are nutritionally beneficial to deer, whereas forests possessed fewer nutritionally beneficial plants and contained an abundance of open ground. However, as plants senesced and forage availability on the landscape decreased during autumn and winter, deer did not prefer any patch type. Our results suggest that in anthropogenically fragmented forests, meadows can provide deer with a potentially overlooked foraging subsidy that should be considered when managing high-density deer populations.

The concept of environmental sustainability formed the basis of the Paris Agreement and the United Nations conference in Rio de Janeiro. Empirically, without environmental sustainability, everything else could fall apart or be aimless. This study investigates factors affecting global environmental sustainability spanning 1966Q1 to 2019Q4. However, there are many micro-/macroeconomic factors engendering the environment, and the absence of robust clarity on whether factors such as economic growth, urbanization, trade openness, and energy consumption matter for global environmental sustainability remains a global academic dilemma in the economics literature. This paper utilized the unrestricted nonlinear autoregressive distributed lag (NARDL) bounds test techniques to model their relationship. Furthermore, the study adopted fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS), and canonical cointegrating regression (CCR) methods to test the research hypothesis, catering to the problem of endogeneity and serial correlation. Up-to-date of this study, no empirical study has examined the nexus of these variables within the global framework. The outcomes suggested that (i) NARDL bounds test of cointegration confirmed evidence of long-run and short-run relationships among the variables; (ii) long-run asymmetric relationship was affirmed among the variables; and (iii) DOLS, FMOLS, and CCR models demonstrate that economic growth, energy consumption, and trade openness are positively significantly correlated with environmental sustainability except for economic growth which shows negative and insignificant correlation. These findings validate the protracted argument in literature that these estimated variables are significant for global environmental sustainability. This study recommends that environmental policymakers integrate global economic incentives with favorable regulatory changes for achieving the goals of a global sustainable environment in the long-run equilibrium.
