“…Besides, species with different ecological needs and dispersal capacities may respond differently to habitat fragmentation, which may be determinant in ensuring the survival of the population (Liao, Bearup, & Blasius, 2017). Landscape connectivity can be explained as the physical arrangement of the vegetation structure in the landscape or by an organism's response to that structure (functional connectivity; Tischendorf & Fahrig, 2000;Xun, Yu, & Wang, 2017). Different approaches have been applied to assess connectivity, including structural metrics and the network approach or graph theory.…”

Assessing landscape connectivity allows us to identify critical areas that impede or facilitate the movement of organisms and their genes and to plan their conservation and management. In this article, we assessed landscape connectivity and ecological condition of the habitat patches of a highly biodiverse region in Chiapas, Mexico. We employed data of three cracid species with different characteristics in habitat use and mobility. The habitat map of each species was derived from a spatial intersection of the models of potential distribution and a high-resolution map of current land cover and land use. The ecological condition of vegetation types was evaluated using 75 field plots. Structure of landscape was estimated by fragmentation metrics, while functional connectivity was assessed using spatially explicit graph analysis. The extent of suitable habitat for Oreophasis derbianus, Penelopina nigra, and Penelope purpurascens correspond to 25%, 46%, and 55% of the study area (5,185.6 km 2 ), respectively. Although the pine-oak forests were the most fragmented vegetation type, habitats of the three species were well connected, and only 4% to 9% of the fragments located on the periphery of the corridor had low connectivity. Landscape connectivity depends mainly on land uses with an intermediate and lower ecological condition (secondary forests and coffee agroforestry systems). Therefore, we suggest that in addition to promoting the improvement in connectivity in fragmented forests, conservation efforts should be aimed at preventing the conversion of mature forests into agricultural uses and maintaining agroforestry systems.

“…Patch 'C' is covered by continuous forest and 'G' is grass/farmland. Larger patch size contributes to a greater intra-patch and inter-patch connectivity in a habitat network [16,19]. They not only offer a larger area of habitat, but also increase the amount of area-weighted dispersal flux [19] and, hence, should to be protected.…”

“…For the focal open-habitat bird species, patch 'E' (Figure 4c) connects the northern and southern key patches. Moreover, patches near large patches (e.g., patch 'F' in Figure 4c) not only facilitates species dispersal, but also acts as a barrier against human disturbance [16]. Loss of such key stepping-stone patches might rapidly reduce the overall connectivity and increase the chance of network collapse [75,76].…”

Rapid urbanization results in changes in land use, biogeochemical cycles, climate, hydrosystems, and biodiversity. Policy-makers have formulated ecological protection measures to facilitate sustainable development. However, traditional conservation planning mainly focuses on protecting specific green spaces, with limited consideration of the connectivity among green spaces from a habitat network perspective. Using citizen science data and occupancy modelling, we predicted habitat suitability, built habitat networks and identified key habitat patches based on their contribution to the functional connectivity of the habitat network for three focal water, forest, and open-habitat bird species. Based on the habitat requirement, small waterbodies and intermediate forest and open-habitat cover facilitate preserving water, forest and open-habitat birds. In regards to the network analysis, we found that key habitat patches with a high conservation priority were generally characterized by a relatively large patch size and/or located at critical positions in the habitat network (at central positions in the habitat network, or near large patches). We suggest that key habitat patches in restricted built-up areas are converted to protected areas or are kept as cropland under future urban planning. We emphasize the usefulness of the focal species concept in urban biodiversity conservation. Our study offers conservation recommendations from a habitat network perspective for urban planners to safeguard urban biodiversity and ecosystem health.

Local environmental policy has recently become the topic of academic research and practices within the context of increased integration of the ecological dimension in the existing regulation of economies and societies, and space. Based on these discussions, local environmental policy is not merely an issue of ecological technology; rather, it is more a question of social power, in particular the power of the state and its ability to balance other forces and demands placed on it by society. The paper draws on this theoretical discussion to capture the multidimensionality of the power relations involved in the approaches to local ecological policy. The evolution of the policy agenda in the city of Shenzhen provides a paradigmatic example of the way in which policies can be shaped by the political considerations that surround and act between nature, governmental departments and society. The empirical results show that the ecological conservation policy of the city has shifted away from comparatively weak ecological regulations towards a stronger set of principles. The comparatively stronger ecological regulatory regime is best understood as a 'biophysical fix' that has been shaped by various forces originating in broader economic, social and institutional struggles.
