The specificity of host-bat fly interaction networks across vegetation and seasonal variation

Vegetation type and seasonality promote changes in the species composition and abundance of parasite hosts. However, it is poorly known how these variables affect host-parasite interaction networks. This information is important to understand the dynamics of parasite-host relationships according to biotic and abiotic changes. We compared the specialization of host-bat fly interaction networks, as well as bat fly and host species composition between upland dry forest and riparian forest and between dry and rainy seasons in a tropical dry forest in Jalisco, Mexico. Bat flies were surveyed by direct collection from bats. Our results showed that host-bat fly interaction networks were more specialized in upland dry forest compared to riparian forest. Bat fly species composition was different between the dry and rainy seasons, while host species composition was different between upland dry forest and riparian forest. The higher specialization in upland dry forest could be related to the differences in bat host species composition and their respective roosting habits. Variation in the composition of bat fly species between dry and rainy seasons coincides with the seasonal shifts in their species richness. Our study confirms the high specialization of host-bat fly interactions and shows the importance of biotic and abiotic factors to understand the dynamics of parasite-host interactions.

“…The most recent review of forest trends in Central America (28) concluded that, although there is room for "cautious optimism" in the sense that the region could follow a FT pathway; the patterns are unclear and limited by the lack of up-to-date forest monitoring. Studies of land change in Central America and other regions in Latin America have identified many socioeconomic factors favoring forest recovery, including: international remittances (29)(30)(31), migration (32)(33)(34)(35), urban/rural population change (36)(37)(38)(39), rural abandonment and accompanying urbanization and industrialization (18,35,40), foreign investment (41), tourism (4), establishment of protected areas (42,43), expansion of shade coffee oriented to global markets (27), establishment of tree plantations (17), and growth of the services economy (44,45). These studies, however, are mostly restricted to one country or a subnational area, and do not discriminate among forest types or ecological subnational regions.…”

Forest transitions (FT) have been observed in many developed countries and more recently in the developing world. However, our knowledge of FT from tropical regions is mostly derived from case studies from within a particular country, making it difficult to generalize findings across larger regions. Here we overcome these difficulties by conducting a recent (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) satellite-based analysis of trends in forest cover across Central America, stratified by biomes, which we related to socioeconomic variables associated with human development. Results show a net decrease of woody vegetation resulting from 12,201 km 2 of deforestation of moist forests and 6,825 km 2 of regrowth of conifer and dry forests. The Human Development Index was the socioeconomic variable best associated with forest cover change. The least-developed countries, Nicaragua and Guatemala, experienced both rapid deforestation of moist forests and significant recovery of conifer and dry forests. In contrast, the most developed countries, Panama and Costa Rica, had net woody vegetation gain and a more stable forest cover configuration. These results imply a good agreement with FT predictions of forest change in relation to socioeconomic development, but strong asymmetry in rates and directions of change largely dependent upon the biome where change is occurring. The FT model should be refined by incorporating ecological and socioeconomic heterogeneity, particularly in multicountry and regional studies. These asymmetric patterns of forest change should be evaluated when developing strategies for conserving biodiversity and environmental services.land-use change | land-cover change | tropics |

“…A "low deforestation" estimate of 17% deforestation across the landscape was derived from interpretation of satellite imagery (Sánchez-Azofeifa et al 2009). A "high deforestation" estimate of 61% of the landscape deforested was calculated from the reported perceptions of the landowners regarding deforestation (Sánchez-Azofeifa et al 2009, Cohen Salgado 2014.…”

. 2016. Trade-offs between ecosystem services and alternative pathways toward sustainability in a tropical dry forest region. Ecology and Society 21 (4) ABSTRACT. The design of strategies aimed at sustainable resource management requires an understanding of the trade-offs between the ecosystem services at stake, to determine appropriate ways in which to navigate them. We assess trade-offs between forage production for cattle ranching and the maintenance of carbon stocks or tree diversity in a Mexican tropical dry forest. Trade-offs between pairs of services were assessed by identifying their efficiency frontiers at both site and landscape scales. We also estimated service outcomes under current and hypothetical land-management conditions. We found stark trade-offs between fodder and carbon stocks and between fodder and tree species richness at the site scale. At the landscape scale, the efficiency frontier was concave, with a much less pronounced trade-off in the fodder-species richness case. Our estimates of current service supply levels showed a reduction of 18-21% for C stock and 41-43% for fodder biomass, relative to the maximum feasible values along the efficiency frontier. Choice of the optimum management strategy to reduce such inefficiency depended on deforestation level: secondary forest regeneration was most suitable when deforestation is low, whereas increased fodder productivity in the pastures is best when deforestation is high. Pasture enrichment with forage trees and secondary forest growth are potential management alternatives for achieving sustainability given the range of enabling ecological factors and to balance ecological and social sustainability given the requirements and preferences of local stakeholders. Given that analogous trade-offs are found across the tropics, this work contributes to reconciling tropical forest maintenance and its use for sustainable rural livelihoods.
