“…Hispaniola is currently divided into two nations with approximately the same population size but differing areas: the larger Dominican Republic in the east and smaller Haiti in the west. Hispaniola's geotectonic history naturally split species into north/south rather than east/west ranges, resulting in species that are distributed across similar ecosystems but face unequal anthropogenic threats built on centuries of differences across a colonial boundary [56].…”

The human-mediated movement of species across biogeographic boundaries—whether intentional or accidental—is dramatically reshaping the modern world. Yet humans have been reshaping ecosystems and translocating species for millennia, and acknowledging the deeper roots of these phenomena is important for contextualizing present-day biodiversity loss, ecosystem functioning and management needs. Here, we present the first database of terrestrial vertebrate species introductions spanning the entire anthropogenic history of a system: the Caribbean. We employ this approximately 7000-year dataset to assess the roles of historical contingency and priority effects in shaping present-day community structure and conservation outcomes, finding that serial human colonization events contributed to habitat modifications and species extinctions that shaped the trajectories of subsequent species introductions by other human groups. We contextualized spatial and temporal patterns of species introductions within cultural practices and population histories of Indigenous, colonial and modern human societies, and show that the taxonomic and biogeographic diversity of introduced species reflects diversifying reasons for species introductions through time. Recognition of the complex social and economic structures across the 7000-year human history of the Caribbean provides the necessary context for interpreting the formation of an Anthropocene biota.

are unimportant in the determination of the species geographic ranges 8-10. However, several studies have demonstrated that the inclusion of biotic interactions in ENMs improves the performance of these models, both at local and regional scales 1,9,11-13. Epiphyte plants are a group that exemplifies the importance of biotic interactions. Such species establish and complete their entire life cycle on the bark of trees, and therefore the distribution of their host tree species strongly influence the distribution of these plants 8,14. However, despite the essential role that biotic interactions play in determining the distribution of some species, very little is known about the functioning of these ecological relationships 5,8,15. Moreover, the importance of the interactions that occur among species at the macro-scale is still subject of debate 8,16. It is expected that climate change will modify the range of an important number of species 17-20 , which may modify the composition of local communities, and may create transient communities that could be dominated by generalists species 21-23. To understand the possible effects of climate change on species distributions and ecosystem relationships, and to promote biodiversity conservation, it is essential to consider all the important drivers of the distribution of species when projecting future changes 24. For species that are highly dependent on biotic interactions, it is necessary to understand the effect of these interactions on their distributions 25,26. For example, currently interacting species may no longer occupy the same areas in the future as a result of climate change, because they could migrate at either different speeds or directions 26-28. Some biotic interactions, such as predation, competition and mutualism, are especially important for the maintenance of biodiversity 29,30 , and they can be decisive in determining the response of interacting species to climate change 11. Biotic interactions are key for evolutionary and ecological processes and mediate the responses of some species to climate 21. Similarly, climate can affect the direction, frequency and intensity of the interactions. Thus, understanding the complexity of the relationship between climate and biotic interactions is essential in order to predict the future habitat distribution of some species, especially those strongly dependent on these interactions. The establishment and abundance of epiphytic plants is largely determined by the microclimatic conditions provided by their host tree, like a protecting shadow and support well above the ground 31,32. This host-guest relationship therefore largely determines the distribution of these epiphyte species 32. Future changes in the distribution of host species due to climate change may thus act to reduce the distribution of epiphytes 11,33. Moreover, these species live in tropical forests, a habitat under particular threat due to changes in both climate and land use 34. Finally, these species are very sensitive to variations in temperature and pr...

17The human-mediated movement of species across biogeographic boundaries-whether 18 intentional or accidental-is dramatically reshaping the modern world. Yet, humans have been 19 reshaping ecosystems and translocating species for millennia, and acknowledging the deeper 20 roots of these phenomena is important for contextualizing present-day biodiversity loss, 21 ecosystem functioning, and management needs. Here, we present the first database of terrestrial 22 vertebrate species introductions spanning the entire anthropogenic history of a system: the 23 Caribbean. We employ this ~7,000 year dataset to assess the roles of historical contingency and 24 priority effects in shaping present-day community structure and conservation outcomes, finding 25 that serial human colonization events contributed to habitat modifications and species extinctions 26 that shaped the trajectories of subsequent species introductions by other human groups. We 27 contextualized spatial and temporal patterns of species introductions within cultural practices and 28 population histories of Indigenous, colonial, and modern human societies, and show that the 29 taxonomic and biogeographic diversity of introduced species reflects diversifying reasons for 30 species introductions through time. Recognition of the complex social and economic structures 31 across the 7,000-year human history of the Caribbean provides the necessary context for 32 interpreting the formation of an Anthropocene biota. 33 34 Caribbean archaeology 36 37 38 39 A wide range of disciplines continue to debate the origin and defining characteristics of 40 the Anthropocene [1]. Yet, an undeniable signal of global human impact is the formation of 41 novel ecosystems and non-analogue assemblages, which have been created by the intentional and 42 accidental movement of species outside their native ranges in the context of land use change and 43 selective extinctions [2]. Human-mediated species translocations have fundamentally changed 44 the planet's biogeographic assembly rules by eroding the barriers separating islands, continents, 45 and hemispheres [3]. This reshaping of species ranges is not unique to present day human 46 societies: today's introduced species are part of a much longer legacy, with the earliest 47 documented translocation occurring approximately 20,000 years ago [4]. Since this Late 48 Pleistocene beginning, the advent of agricultural domestication and advancement of maritime 49 technology vastly increased the number of translocations and the geographic distance of the 50 translocation in the Holocene [5], and subsequently, colonial trade, industrial shipping, and the 51 wide-ranging effects of globalization have generated the Anthropocene biota that define our 52 modern landscapes [6]. 53 The ecological and economic impacts of such translocated species today are intensively 54 studied in management contexts, but whether and how the long-term (millennial-scale) sequence 55 of human-mediated species introductions have hindered or promoted subsequent introd...
