Aim: Transboundary conservation is key to addressing poleward range shifts that will result from climate change. At a species level, transboundary coordination may be hindered by inter‐country differences in protection of species. We explored how commonly mammal ranges in the Americas were transboundary, identified transboundary mammals whose poleward versus equatorial range limits fell in different countries and examined asymmetries in listing status of mammals. Location: The Americas. Methods: We intersected mammal ranges with country boundaries to identify transboundary species. We then determined the conservation status of mammals at the national level by compiling a database of all national‐level listing status documents across the Americas and at the global level through use of the IUCN Red List database. Results: Over 62% (1,114 species) of mammals were transboundary in any cardinal direction, and over 50% (850 species) had poleward and equatorial range limits in different countries. Of those 850, 26% experienced asymmetric listing, with one range limit designated at a higher listing status than the other at the national level. Mismatches between national and global listing also were apparent at equatorial and poleward range edges. These same general patterns held when our analyses were restricted to globally at‐risk mammals. Main Conclusions: Although listing status of a species does not necessarily equate to actual level of protection, these results demonstrate that formal listings of species vary substantially across country boundaries, and in particular at the latitudinal range extremes. Asymmetries in listing could indicate that species are under less threat in one country compared to another or could reflect different levels of concern in the two countries although population status is similar. Regardless, asymmetries in listing could challenge cross‐border connectivity and climate change resilience in the face of species range shifts and indicate the need for greater transboundary coordination in species management.

In the space between Aboriginal sovereignty and national security: Re‐engaging border security and Mohawk culture at Akwesasne Based on the case of the Mohawk territory of Akwesasne, wedged between Ontario, Quebec, and New York state, this paper provides an analysis of the links between the affirmation of indigenous culture and the implementation of security policies on borderlands. The focus extends beyond political conflicts over border issues to encompass the ways in which Aboriginal sovereignty is affirmed within processes of negotiation and cooperation in the matters of identification requirements, border agents' cultural sensitivity, and law enforcement. We find that the enhancement of border security can paradoxically be a political opportunity for local leaders to reaffirm indigenous sovereignty, and that this reaffirmation through cooperation is, at the same time, emerging as a key factor in the implementation of border security policies. Messages clés: Affirmation identitaire transfrontalière et politiques de sécurité se renforcent mutuellement.Les mesures de sécurité sont appropriées localement par les dirigeants indigènes.L'intégration de considérations culturelles dans les politiques de sécurité contribue à la mise en oeuvre de ces dernières.

The Great Lakes and St. Lawrence binational region is one of the most significant concentrations of industrial production on earth and contains the most active corridors for goods movements in the Canada‐United States trade relationship. The history of industrial development in this region involves the exploitation of coal and iron ore for steel production, the development of the railroads and the expansion of commercial agriculture, and the growth of the automotive and other high value‐added manufacturing industries. Canadian and American industrial complexes became increasingly integrated with the support of trade agreements in the latter decades of the 20th century. Development of cross‐border supply chains led to massive international flows of intermediate goods. In this context, the performance of a few key border crossings is of critical economic importance. New information drawn from very large datasets of Global Positioning System records generated by cross‐border truck movements sheds new light on both the spatial patterns of cross‐border goods movement and the performance of border crossings. Key Messages: The history of industrial development in the Great Lakes and St. Lawrence region involves steel production, the development of railroads, and the expansion of key industries.Canada‐US trade agreements led to very large volumes of cross‐border trade at Great Lakes crossings, characterized by integrated cross‐border supply chains.GPS data from trucks provide a new opportunity to study the spatial patterns of Canada‐US trade and the performance of border crossings.

Various critical and scholarly works have underlined the multiplicity of borders, or the idea that borders mean different things to different people. This paper discusses the potential of the concept of assemblage for better understanding the ontological multidimensionality intrinsic to borders. An assemblage is understood to be a heterogeneous and open-ended grouping of elements that do not form a coherent whole that helps explain how different meanings emanating from various actors may interact and endure in a contingent and provisional way. It can be argued that such a topological approach may be well suited to highlight the overall significance of a border's identity beyond its diversity and on-going transformation.

The reconfiguration of political space lies at the heart of the European project and is the subject of manifold studies on the new shape of the European Union, but relatively little attention has been paid to the ways in which borders are de- and reconstructed in a pan-European labour market. In a pan-European labour market, state borders shift. Postings made via subcontractors and agencies providing temporary workers also rearrange the borders of the firm. However, we know very little about how these bordering practices interact within the pan-European labour market. This study argues that while borders have become porous, their porousness is one-directional, in the sense that it is in favour of capital but impacts negatively on labour rights. In developing a framework for understanding the relationship between changes in sovereign borders and changes in employment relations in the EU, this article integrates insights from international relations, political economy and border research.

Based on ethnographic research in Puerto Iguazú, an Argentine town bordering Brazil and Paraguay, this article explores how journalists maneuver between stories for, on, and off the record to maintain a locally valid boundary between law and crime. Journalists occupy a multifaceted position in the Iguazú community: as residents, they often participate in the informal circulation of legal and illegal goods across the border; as cultural producers, they create representations about it. Coverage relating to informal trade depends on local schemes of legality and legitimacy that juxtapose the rights and rules for those living in this small border community with national legislation, which disadvantages the remote town and serves to obstruct cross-border exchanges. Due to the discrepancy between local understanding of legality and national laws, many potentially newsworthy illegal exchanges are not addressed in the media. On the border, where consensus regarding the legality and legitimacy of many common practices is unstable, this article shows how local news production plays an important part in determining what is legal, illegal, legitimate, or illicit.

This contribution examines the development of territorial dynamics on the Ceuta-Morocco border region in the context of the structural Spanish-Moroccan rebordering that followed Spain's EU entry. The evolution of border practice is canvassed through the confronting notions of territorial discontinuity and territorial continuity. Clearly, current territorial dynamics between Ceuta and Morocco are characterised by both the existence of conflictive geopolitical cross-border dialectics and the implementation of fortifying securitisation measures. However, simultaneously, the border region is also marked by intensifying patterns of cross-border interaction which are sourced in the rising potentialities of economic and urban cross-border co-operation. In this light, the paper seeks to map the present intertwining of these apparently disagreeing territorial trends. To conclude, the paper underlines the ongoing modification of relational power between Ceuta and Morocco. It depicts the strengthening of local cross-border co-operative practices as a potential tool to cope with persistent sovereignty disputes in the border region. [ABSTRACT FROM AUTHOR]

This paper tries to accomplish cross-fertilisation between border studies and transmigration studies, research fields which exist almost separated from each other. It claims that the concept of border can contribute to the theoretical growth to maturity of the relatively young field of transmigration studies, and especially to a deeper understanding of the in-between lifeworlds of transmigrants (migrant transnationalism). In transmigration studies, borders are usually considered as boundaries, the physical lines on the ground, and therefore are seen as beginnings and endings of migrant transnationalism. In this paper, it is argued that borders can also have a constitutive role in migrant transnationalism. This constitutive function of borders has been thoroughly theorised in border studies in the last two decades. Contemporary border scholars regard borders not as passive lines, but as active and polymorphous social constructions which are the outcome of people's need to make differences. By bringing this broader notion of borders to the transmigration debate, it is argued that migrant transnationalism is about experiencing the border, or experiencing the difference. This broader sense of borders might help to bare the soul of migrant transnationalism, namely the condition of being continuously between here and there. [ABSTRACT FROM AUTHOR]

The number of exotic ant species being dispersed to new regions by human transportation and the trade pathways responsible for this are poorly understood. In this study, the taxonomic diversity, trade pathways, and origin of exotic ants intercepted at the New Zealand border were examined for the period 1955–2005. Overall, there were a total 4355 interception records, with 115 species from 52 genera. The 10 most frequently intercepted genera, and the 20 most frequently intercepted species contributed > 90% of all records. Many of the species frequently intercepted are regarded as invasive species, and several are established in New Zealand. The most intercepted species was Pheidole megacephala. Despite a relatively low trade relationship, a high proportion (> 64%) of the exotic ants which were intercepted originated from the Pacific region. However, the majority of species intercepted from the Pacific was exotic to the region (71%), or to a lesser extent, wide-ranging Pacific native species. No endemic species from the Pacific were intercepted. The effectiveness of detecting exotic ant species at the New Zealand border ranged from 48–78% for different trade pathways, indicating a number of species remain undetected. Trade routes associated with specific geographical regions represent a major filter for the arrival of exotic ant species. Despite the importance of the Pacific as a frequent pathway, we suggest that the future establishment of exotic ant species in New Zealand is likely to be mitigated by a renewed focus on trade routes with cool temperate regions, particularly Australia.
