Key information needs to move from knowledge to action for biodiversity conservation in Canada

Biological Conservation, Год журнала: 2021, Номер 256, С. 108983 - 108983

Опубликована: Фев. 18, 2021

To address the ongoing global biodiversity crisis, conservation approaches must be underpinned by robust information. Canada is uniquely positioned to contribute meeting targets, with some of world's largest remaining intact ecosystems, and a commitment co-application Indigenous ways knowing alongside scientific, socioeconomic, other approaches. We elicited input from experts across range disciplines identify key information needed advance policy management actions conserve in Canada. Experts concluded that, many cases, lack not major barrier conservation; instead, mechanisms translate into action are most urgently needed. Recognizing multiple knowing, especially knowledge systems, will critical support transformative change at national scale. Collaboration among natural, social data scientists can facilitate management. identified 50 priority needs which emphasize importance (i) reviewing policies disseminating lessons learned successes failures; (ii) better understanding build public support; (iii) improving, specific instances, status trends habitats, species, threats for planning management; (iv) mobilizing Through Convention on Biological Diversity, community has resolved "live harmony nature"; through our Canadian case-study, we conclude that pressing need this resolution an improved how move action.

Understanding Local Adaptation to Prepare Populations for Climate Change

BioScience, Год журнала: 2022, Номер 73(1), С. 36 - 47

Опубликована: Ноя. 30, 2022

Abstract Adaptation within species to local environments is widespread in nature. Better understanding this adaptation critical conserving biodiversity. However, conservation practices can rely on species’ trait averages or broadly assume homogeneity across the range inform management. Recent methodological advances for studying provide opportunity fine-tune efforts managing and species. The implementation of these will allow us better identify populations at greatest risk decline because climate change, as well highlighting possible strategies improving likelihood population persistence amid change. In present article, we review recent study highlight ways tools be applied efforts. Cutting-edge are available help characterize adaptation. Indeed, increased incorporation management decisions may meet imminent demands a rapidly changing world.

A metric‐based framework for climate‐smart conservation planning

Ecological Applications, Год журнала: 2023, Номер 33(4)

Опубликована: Март 22, 2023

Abstract Climate change is already having profound effects on biodiversity, but climate adaptation has yet to be fully incorporated into area‐based management tools used conserve such as protected areas. One main obstacle the lack of consensus regarding how impacts can included in spatial conservation plans. We propose a climate‐smart framework that prioritizes protection refugia—areas low exposure and high biodiversity retention—using metrics. explore four aspects planning: (1) model ensembles; (2) multiple emission scenarios; (3) metrics; (4) approaches identifying refugia. illustrate this Western Pacific Ocean, it equally applicable terrestrial systems. found all planning considered affected configuration The choice metrics refugia have large resulting plans, whereas models scenarios smaller effects. As plans depended used, plan based single measure (e.g., warming) will not necessarily robust against other measures ocean acidification). therefore recommend using most relevant for region or drivers. To include uncertainty associated with different futures, we (i.e., an ensemble) scenarios. Finally, show identify feature trade‐offs between: degree which they are climate‐smart, their efficiency meeting targets. Hence, approach depend relative value stakeholders place adaptation. By framework, areas designed improved longevity thus safeguard current future change. hope proposed helps transition toward approaches.

30×30 biodiversity gains rely on national coordination

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Ноя. 6, 2023

Global commitments to protect 30% of land by 2030 present an opportunity combat the biodiversity crisis, but reducing extinction risk will depend on where countries expand protection. Here, we explore a range 30×30 conservation scenarios that vary what dimension is prioritized (taxonomic groups, species-at-risk, facets) and how protection coordinated (transnational, national, or regional approaches) test which decisions influence our ability capture in spatial planning. Using Canada as model nation, evaluate well each scenario captures using scalable indicators while accounting for climate change, data bias, uncertainty. We find only 15% all terrestrial vertebrates, plants, butterflies (representing 6.6% species-at-risk) are adequately represented existing protected land. However, nationally approach could 65% species representing 40% species-at-risk. How has largest impact, with approaches protecting up 38% fewer choice incurs much smaller trade-offs. These results demonstrate potential highlighting critical importance biodiversity-informed national strategies.

Animal migration in the Anthropocene: threats and mitigation options

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2024, Номер 99(4), С. 1242 - 1260

Опубликована: Март 4, 2024

ABSTRACT Animal migration has fascinated scientists and the public alike for centuries, yet migratory animals are facing diverse threats that could lead to their demise. The Anthropocene is characterised by reality humans dominant force on Earth, having manifold negative effects biodiversity ecosystem function. Considerable research focus been given assessing anthropogenic impacts numerical abundance of species/populations, whereas relatively less attention devoted animal migration. However, there clear linkages, example, where human‐driven behaviour can population/species declines or even extinction. Here, we explore (in all domains – aquatic, terrestrial, aerial) using International Union Conservation Nature (IUCN) Threat Taxonomy classifications. We reveal (e.g. human development, disease, invasive species, climate change, exploitation, pollution) impact wildlife in varied ways spanning taxa, life stages type from direct mortality changes behaviour, health, physiology). Notably, these often interact complex unpredictable detriment wildlife, further complicating management. Fortunately, beginning identify strategies conserving managing Anthropocene. provide a set that, if embraced, have potential ensure animals, important ecological functions sustained migration, persist.

Incorporating climate velocity into the design of climate‐smart networks of marine protected areas

Methods in Ecology and Evolution, Год журнала: 2021, Номер 12(10), С. 1969 - 1983

Опубликована: Июль 22, 2021

Abstract Climate change is redistributing terrestrial and marine biodiversity altering fundamental ecological interactions. To conserve promote its long‐term persistence, protected areas should account for the implications of species’ redistribution. Data paucity across many systems means that achieving this goal requires generic metrics act as proxies likely responses multiple taxa to climate change. velocity one such metric, representing potential speed direction range shifts. Here, we explore three approaches incorporating into design demonstrate their application in Mediterranean Sea. Our methods are designed meet climate‐smart adaptation strategy protecting refugia by selecting slow‐moving areas. For our case study, found a cost measure Marxan best selects slower moving areas, which robust indicators refugia. However, approach unable accommodate socio‐economic data thus impractical. Incorporating boundary or feature with lower cost. We recommend boundary, where possible because it more flexible approach. The considers all planning units, rather than being limited subjective classification ‘slow‐moving’ units when treated feature. further assessment required. different scales grid structures other squares, relative performance might vary among studies.
