“…In China, many regions have undergone large deforestations in response to the demographic pressure, in order to create new croplands (see review in [28]). In the Ganzu province, this deforestation has caused profound landscape modifications and simultaneous changes in the rodent populations [28,29].…”

“…This has already entailed consequences for one human disease: alveolar echinococcosis, with an increase in the number of human cases [29]. Yet this province is also a plague focus [31] and the rodent species that benefit from an increase in open land (crops or steppes) are also plague reservoirs: the number one plague reservoir in this focus, Spermophilus alaschanicus, does not exist in dense forests, yet it can be encountered in open woodlands and it proliferates in prairies and steppes; two other rodents found carrying plague in this area, Myospalax fontanieri and Tscherkia triton are now dominant species in farmlands [28].…”

-Re-emergence of human cases of plague after decades of silence does not necessarily mean that plague foci are re-emerging. Most often, Yersinia pestis bacteria have been maintained and circulating at low levels in the rodent populations. It seems therefore more appropriate to speak in terms of expansion or regression phases for sylvatic rodent plague foci and to reserve the term reemergence for human cases. From the analysis of well-documented human plague cases in Madagascar, we underline the causes of re-emergence that can be generalized to most world foci, and can help define environments at risk where the threat of new emergence lurks. In all recent plague outbreaks, usually more than one risk factor was at the origin of the re-emergence. The reduction or discontinuance of surveillance and control, as well as poverty and insalubrity are the main factors in the re-emergence of human cases, allowing increased contacts with infected rodents and fleas. Environment changes (i.e. climatic changes, deforestation, urbanization) induce changes in flea and rodent populations by (i) extension of rodent habitats (for example by replacing forests by steppes or farmlands); (ii) modifications in population dynamics (possible outbreaks due to an increase of available food resources); but also, (iii) emergence of new vectors, reservoirs and new Y. pestis genotypes. Numerous and spontaneous genomic rearrangements occur at high frequencies in Y. pestis, which may confer selective advantages, enhancing the ability of Y. pestis to survive, to be transmitted to new hosts, and to colonize new environments. Therefore, any environmental change should be taken as a warning signal and active surveillance programs should be initiated.

“…The beneficial impact of landscape heterogeneity, stand structural complexity and use of native tree species for afforestation on biodiversity has been highlighted (Thompson et al 2003, Lindenmayer andHobbs 2004). Less attention has been paid however on the distribution of small mammals in the successions of habitats resulting from deforestation (Giraudoux et al 1998, Bryja et al 2002, Scott et al 2006 or afforestation (Johnson et al 2002, Moser et al 2002, Liang and Li 2004, Men et al 2006). To our knowledge, only one study has simultaneously considered the effect of deforestation and plantation on small mammal assemblages within a given area (Nakagawa et al 2006, in Malaysia).…”

Deforestation is a major environmental issue driving the loss of animal and plant species. Afforestation has recently been promoted to conserve and restore Chinese forest ecosystems. We investigated the distribution of small-mammal assemblages in an area where forest and associated deforestation habitats dominate and in an agricultural area where afforestation is ongoing in the Loess Plateau of southern Ningxia Autonomous Region, P.R. China. Multiple trapping was used. Assemblages were defined based on the multinomial probability distribution and information theory. Species turnover between assemblages of deforested and afforested habitats was high, although no clear effect on species richness was observed. The two assemblages described along the deforestation gradient displayed higher diversity, whereas diversity was lower in assemblages identified in afforested habitats where Cricetulus longicaudatus, known agricultural pest in various areas of China, clearly dominated. The threatened Sorex cylindricauda and Eozapus setchuanus were recorded along the deforestation gradient but not in plantations. Therefore, habitats present along a deforestation succession in this part of Ningxia sustain a high diversity of small mammals and include species of conservation concern. At the present stage of its process (maximum 15 years), afforestation in southern Ningxia favours the dominance of an agricultural pest.

“…Epidemiological and ecological studies have been carried on since the 1980s in the Jura Mountains, France (Delattre, Pascal & Damange, 1985 ;Delattre et al 1988 ;Delattre, Giraudoux & Quere, 1990 ;Giraudoux, 1991 ;Bresson-Hadni et al 1994 ;Viel et al 1999 ;Raoul, 2001), and in Southern Gansu, China (Craig et al 1992 ;Giraudoux et al 1998 ;Courant et al 1999 ;Craig et al 2000). The present paper analyses and compares results obtained in both regions and suggests that at the regional scale landscape can affect human disease distribution through interaction with small mammal communities and their population dynamics.…”

An area close to the Qinghai-Tibet plateau region and subject to intensive deforestation contains a large focus of human alveolar echinococcosis while sporadic human cases occur in the Doubs region of eastern France. The current review analyses and compares epidemiological and ecological results obtained in both regions. Analysis of rodent species assemblages within quantified rural landscapes in central China and eastern France shows a significant association between host species for the pathogenic helminth Echinococcus multilocularis, with prevalences of human alveolar echinococcosis and with land area under shrubland or grassland. This suggests that at the regional scale landscape can affect human disease distribution through interaction with small mammal communities and their population dynamics. Lidicker's ROMPA hypothesis helps to explain this association and provides a novel explanation of how landscape changes may result in increased risk of a rodent-borne zoonotic disease.
