“…Climate change can further increase toxicity of contaminants via warmer temperatures (Mann et al, 2009; Viswanathan & Murti, 1989). Furthermore, synergies among mixtures of contaminants are complex (Edge et al, 2020) and outcomes are further complicated by species differences in physiological tolerances and changing interspecific relationships. These stressors interact and increase chronic stress for salamanders and other amphibians, slowing development in these ephemeral habitats and reducing fitness (Griffis‐Kyle, 2016; Ladewig, 2010).…”

Climate change, interacting with and exacerbating anthropogenic modifications to the landscape, is altering ecosystem structure and function, biodiversity, and species distributions. Among the most visible short-term impacts are the altered ecological roles of foundation species-those species, native or non-native-that create locally stable environmental conditions and strongly influence ecosystem services. Understanding the future of these species is crucial for projecting impacts on ecosystem services at both local and regional scales. Here we present foundation species by ecoregion study cases across the US South-Central Region (Louisiana, New Mexico, Oklahoma, and Texas), including C 4 grasses, mesquite, and northern bobwhite in the Southern Great Plains, mangroves and nutria in coastal Louisiana wetlands, tiger salamanders and sandhill cranes in wetlands of the Southern Great Plains, and post and blackjack oaks and eastern redcedar in the Cross Timbers ecoregion. These case studies explore the impacts of climate change on foundation species and the consequences for ecosystem services, the outlook for climate adaptation efforts, and the sustainability of restoration in these systems. We underscore risks and vulnerabilities that stakeholders should consider when managing or restoring natural resources and conserving ecosystem services in an increasingly extreme and variable climate. We show that past management, through a lack of understanding or implementation of actions, has exacerbated shifts in invasive species, resulting in significant changes in ecosystem structure and function. These changes, interacting with landscape fragmentation and shifting land use and exacerbated by climate change, can result in critical losses of biodiversity. Unfortunately, lack of public understanding may hinder political support for restoration efforts and climate adaptation strategies crucial for the continued supply of traditional ecosystem services. Furthermore, the resulting invaded systems may provide opportunities for income via new ecosystem services valued by society that may reduce support for restoration to historical baselines, thus further shifting management priorities.

“…Another common source of conflict surrounds the negative effects of chemical run-off on surrounding ecosystems (Packer, 2019). Although the negative effects of chemical run-off on the environment (and on people) is increasingly well known, pesticide and herbicide application (often above recommended limits) is frequently applied to areas close to important natural ecosystems (Edge et al, 2020;Vandergragt, Warne, Borschmann, & Johns, 2020). We highlight this in Table 1 with an example of someone applying herbicide close to a national park.…”

The role of a conservation scientist has never been more challenging. Amidst the rapid degradation occurring across Earth's natural ecosystems and the loss of biodiversity and ecosystem services, conservation scientists must learn new and effective ways to build trust and engage with the wider community. Here, we discuss the potential utility of a particular communication technique, Nonviolent Communication (also known as Compassionate Communication or Collaborative Communication), in conservation science. Nonviolent Communication is a structured form of communication, developed in the 1960s by Dr. Marshall Rosenberg, that seeks to foster interpersonal understanding and connection through communication of judgment-free observations, recognition of people's feelings, needs and values, and requests for specific actions to meet those needs. It has delivered positive outcomes in diverse fields such as prisoner reform, health science, and social work, and holds great promise for conservation applications. While there is no single communication strategy that resonates with all people, we argue that Nonviolent Communication could be used by conservation scientists and practitioners when communicating with colleagues, politicians, and the general public about important and sometimes contentious environmental issues.

“…Common reed eradication represents an anthropogenic disturbance (Sullivan and Sullivan 2003), whereas the dune washout is 1 step of a cyclical process of dune overwash and reformation that occurs in Long Point and represents a natural disturbance (Davidson‐Arnott and Fisher 1992, Hesp 2002). Both disturbances have the capacity to increase vegetation and land cover heterogeneity hence altering the distribution of species, and potentially increasing the local biodiversity (Ward 1998, Edge et al 2020). Despite the documented benefits of removing the reeds for many different species, the method of common reed eradication may have non‐target effects such as hypoxia due to nutrient input from the activities of decomposing aerobic and anaerobic bacteria decaying the vegetation (Polunin 1984) and, to a lesser extent, the degradation of glyphosate molecules (Tu et al 2001, Hébert et al 2019, Fugère et al 2020).…”

Natural disturbance allows multiple anuran taxa to persist in a dynamic wetland complex

The maintenance of biological diversity is frequently enhanced in a heterogenous landscape by some level of disturbance. Thus, when a landscape becomes stabilized and homogenized through the spread of an invasive plant species, there may be consequences for native biodiversity, particularly for those biotas that depend on the pre‐existing, natural disturbance regime of that landscape. At Long Point, Ontario, Canada, a sandspit in Lake Erie, the community of anuran amphibians experienced the co‐incidence of 2 major disturbance events, 1 anthropogenic and 1 natural: an intervention to remove the invasive form of the common reed (Phragmites australis australis) and a spate of extensive dune washouts caused by high water levels and storms. As a result of the unequal distribution of disturbance in the landscape, different areas were affected by only the dune washouts, only the common reed treatment, both disturbances, or neither disturbance. From May to August 2021, we explored how the disturbances affected the resident frog and toad species habitat associations in the 4 different disturbance conditions in the landscape. By means of minnow traps, acoustic surveys, and visual surveys, we determined that the dune washouts had a greater influence on resident anurans than the common reed treatment. Ranid frogs (Ranidae) tended to inhabit non‐washout sites, whereas Fowler's toads (Anaxyrus fowleri) congregated in the newly formed, sand flats and shallow, de‐vegetated pools resulting from the washouts. Neither ranid frogs nor Fowler's toads demonstrated avoidance of the sites affected by the herbicide treatment and mechanical rollover of the common reed. This evidence of species sorting, which enables multiple species to persist in a dynamic and heterogeneous landscape, suggests that wildlife management in aid of threatened species recovery may find success by encouraging natural disturbance regimes in dynamic landscapes. Future management endeavors should consider refraining from complete dune stabilization in these landscapes to allow the natural washouts to occur at a higher frequency, while ensuring the continued effectiveness of the invasive common reed eradication.
