Large carnivores' fear of the human ‘super predator’ has potential to alter their feeding behaviour and result in human-induced trophic cascades. However, it yet be experimentally tested if large carnivores perceive humans as predators react strongly enough have cascading effects on prey. We conducted a predator playback experiment exposing pumas (human) non-predator control (frog) sounds at puma sites measure immediate responses subsequent impacts feeding. found that fled more frequently, took longer return, reduced overall time by than half response hearing predator’. Combined with our previous work showing higher kill rates deer urbanized landscapes, this study reveals is mechanism driving an ecological cascade from increased predation deer. By demonstrating can cause strong reduction pumas, results support non-consumptive forms disturbance may role carnivores.

How can we manage farmlands, forests, and rangelands to respond the triple challenge of Anthropocene-biodiversity loss, climate change, unsustainable land use? When managed by using biodiversity-based techniques such as agroforestry, silvopasture, diversified farming, ecosystem-based forest management, these socioeconomic systems help maintain biodiversity provide habitat connectivity, thereby complementing protected areas providing greater resilience change. Simultaneously, use management improve yields profitability more sustainably, enhancing livelihoods food security. This approach "working lands conservation" create landscapes that work for nature people. However, many challenges impede uptake practices. Although improving voluntary incentives, market instruments, environmental regulations, governance is essential support working conservation, it community action, social movements, broad coalitions among citizens, businesses, nonprofits, government agencies have power transform how protect environment.

Loss of species and degradation ecosystems are likely further accelerate in the coming years. Our understanding this crisis now clear, world leaders pledged avert it. Nonetheless, global goals reduce rate loss mostly not achieved. However, many examples conservation success show that losses can be halted even reversed.

Trophic rewilding is an ecological restoration strategy that uses species introductions to restore top-down trophic interactions and associated cascades promote self-regulating biodiverse ecosystems. Given the importance of large animals in their widespread losses resulting downgrading, it often focuses on restoring functional megafaunas. increasingly being implemented for conservation, but remains controversial. Here, we provide a synthesis its current scientific basis, highlighting as key conceptual framework, discussing main lessons learned from ongoing projects, systematically reviewing literature, unintentional spontaneous wildlife comebacks underused sources information. Together, these lines evidence show may be restored via reintroductions replacements.

Abstract The fear large carnivores inspire, independent of their direct killing prey, may itself cause cascading effects down food webs potentially critical for conserving ecosystem function, particularly by affecting herbivores and mesocarnivores. However, the evidence this has been repeatedly challenged because it remains experimentally untested. Here we show that manipulating in free-living mesocarnivore (raccoon) populations using month-long playbacks carnivore vocalizations caused just such effects, reducing foraging to benefit mesocarnivore’s which turn affected a competitor prey prey. We further report restoring our study system, where most have extirpated, succeeded reversing impacts. suggest results reinforce need conserve given significant “ecosystem service” them provides.

The majority of the world's terrestrial large carnivores have undergone substantial range contractions and many these species are currently threatened with extinction. However, there has been little effort to fully quantify extent carnivore contractions, which hinders our ability understand roles relative drivers such trends. Here we present analyse a newly constructed comprehensive set contraction maps. We reveal ranges contracted since historical times identify regions biomes where particularly large. In summary, that experienced greatest include red wolf (Canis rufus) (greater than 99%), Ethiopian simensis) (99%), tiger (Panthera tigris) (95%) lion leo) (94%). general, occurred in Southeastern Asia Africa. Motivated by ecological importance intact guilds, also examined spatial guilds both for entire world regionally. found occupy just 34% land area. This compares 96% historic times.

Abstract Human–wildlife conflict (HWC) is a key topic in conservation and agricultural research. Decision makers need evidence‐based information to design sustainable management plans policy instruments. However, providing objective decision support can be challenging because realities perceptions of human–wildlife interactions vary widely between within rural, urban, peri‐urban areas. Land users who incur costs through wildlife argue that wildlife‐related losses should compensated prevention subsidized. Supporters coexistence policies, such as urban‐dwelling people, may not face threats their livelihoods from wildlife. Such spatial heterogeneity the cost benefits living with germane most contemporary societies. This Special Section features contributions on wildlife‐induced damages range human perspectives (land use, psychology, governance, local attitudes perceptions, benefits, HWC theory) ecological (animal behavior). Building current literature articles this section, we developed conceptual model help frame dimensions. The framework used determine damage implementation levels approaches resolution.
