“…This could be related to the recent rise in storm intensity associated with global climate change, which in the region of Chamela, was evidenced by the direct impact of two large hurricanes, Jova in 2011 (category 3) and Patricia in 2015 (category 5). The impacts of hurricanes was evidenced by dramatic changes in vegetation greenness (89) and across extensive areas of fallen trees and branches across the Chamela-Cuixmala Biosphere Reserve (89,90). These events possibly created a reduction in the availability of nesting cavities and floral resources for bees.…”

Bees play a pivotal role as pollinators in crops crucial for human consumption. However, the global decline in bee populations poses a significant threat to pollination services and food security worldwide. The loss and fragmentation of habitats due to land-use change are primary factors contributing to bee declines, particularly in tropical forests facing high deforestation rates. Here we evaluate the pollination services on crops of watermelon (Citrullus lanatus) and green tomato (Physalis ixocarpa) in the Tropical Dry Forest of Jalisco, Mexico during 2008, and 2014 to 2017. We describe pollinator community composition and visitation frequency and evaluate pollinator contribution to plant reproductive success and degree of pollinator dependence for each crop species. We also assess how landscape configuration influences the abundance and richness of pollinators, and we use the model Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) to map and value the pollination service in both crops. Our findings reveal that the main pollinator of both crops was Apis mellifera, one of the few abundant pollinators in the study region during the dry season, when watermelon and green tomato are cultivated. Results revealed that in the absence of pollinators, watermelon yielded no fruits, while green tomato experienced a 65% reduction in production. For green tomato, fruit set was positively correlated with pollinator abundance. A positive association between forest cover and total pollinator abundance was observed in green tomato in 2008, but not in watermelon. We also found a positive relationship between the abundance of bees predicted by the InVEST model and the abundance of bees observed in green tomato flowers in 2008. In the study region, green tomato and watermelon rely on pollinators for fruit production, with honeybees (from feral and managed colonies) acting as the most importante provider of pollination services for these crops. Consequently, the conservation of natural protected areas is crucial for sustaining pollinators and ensuring food security.

“…In second place, we have a record of the impact of two hurricanes in the region of Chamela, which occurred after the sampling carried out in 2008, Jova in 2011 (category 3) and Patricia in 2015 (category 5). The impacts of hurricanes were evidenced by dramatic changes in vegetation greenness [ 107 ] and across extensive areas of fallen trees and branches across the Chamela-Cuixmala Biosphere Reserve [ 107 , 108 ]. Although a previous study demonstrated positive effects of Hurricane Patricia on herbivorous and predatory insects [ 109 ], it has been shown that bees can be susceptible to natural catastrophic events such as hurricanes, which can significantly reduce bee diversity [ 110 ].…”

Bees play a pivotal role as pollinators in crops essential for human consumption. However, the global decline in bee populations poses a significant threat to pollination services and food security worldwide. The loss and degradation of habitats due to land use change are primary factors contributing to bee declines, particularly in tropical forests facing high deforestation rates. Here, we evaluate the pollination services provided to crops of watermelon (Citrullus lanatus) and green tomato (Physalis ixocarpa) in three municipalities in the state of Jalisco, Mexico, a place with Tropical Dry Forest, during years 2008, and 2014 to 2017. Both crops are cultivated in the dry season, approximately during the months of November to March. We describe the composition of the pollinator community and their visitation frequency (measured through the number of visits per flower per hour), and we assess the impact of pollinators on plant reproductive success and the level of pollinator dependence for each crop species (measured through the number of flowers that developed into fruits). We also evaluate how the landscape configuration (through the percentage of forest cover and distance to the forest) influences richness and abundance of pollinators (measured as number of species and individuals of pollinators per line of 50 m), and we use the model Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) to map and value the pollination service in both crops. InVEST Crop pollination model is a simulation focuses on wild pollinators providing the pollinator ecosystem service. Our findings indicate that Apis mellifera was the primary pollinator of both crops, one of the few abundant pollinators in the study region during the dry season. In experiments where pollinators were excluded from flowers, watermelon yielded no fruits, while green tomato experienced a 65% reduction in production. In the case of green tomato, fruit set showed a positive correlation with pollinator abundance. A positive association between forest cover and total pollinator abundance was observed in green tomato in 2008, but not in watermelon. Additionally, a positive relationship was observed between the abundance of bees predicted by the InVEST model and the abundance of bees observed in green tomato flowers in 2008. In the study region, green tomato and watermelon rely on pollinators for fruit production, with honeybees (from feral and managed colonies) acting as the primary provider of pollination services for these crops. Consequently, the conservation of natural areas is crucial to provide food and nesting resources for pollinators. By doing so, we can ensure the diversity and abundance of pollinators, which in turn will help secure food security. The findings of this study underscore the critical need for the conservation of natural areas to support pollinator populations. Policymakers should prioritize the protection and restoration of habitats, particularly tropical forests, which are essential for maintaining the diversity and abundance of pollinators.

“…To advance knowledge applicable to all forest types and contexts areas that are exposed to cyclonic activity, we must explicitly study forests in a variety of landscape setting and contexts: coastal, dry, urban, novel, among others. Moreover, resource managers and the broader community seek to develop plans to implement actions before and after storms in community forests, agroforestry systems, urban, and suburban interface areas (Imbert, 2018;Lazos-Chavero et al, 2018;Perfecto et al, 2019;Landry et al, 2021;Rodríguez-Cruz and Niles, 2021;Torres-Martínez et al, 2021) and they often need to decide on priorities for management actions in multiple forest contexts and landscape settings. Consequently, understanding forest effects, processes, and subsequent response and recovery time scales in a variety of contexts and settings can serve to guide decision-making and management actions needed to build resilience in the ecological, social, and technological systems in which forest are embedded.…”

Most of the knowledge of tropical storm effects on forests is from studies conducted in reserves and protected areas. Effects on other settings such as urban forests, coastal forests, and in landscapes with mixed land uses and covers are, comparatively, less studied. Yet research from a range of forest types and landscape compositions is needed to inform actions associated with management, mitigation, or restoration efforts before and after storms. Studies of forests comprising various conditions, along with long-term observations, would offer unique insights into the varied and cumulative effects of tropical storms on forest ecosystems. The Caribbean island of Puerto Rico is one of the sites where most tropical storm-forest studies are conducted, yet studies come from a limited set of sites. Using Puerto Rico as a case study, we emphasize the need for broader research approaches that represent the wider range of forests that are exposed to tropical storms. Such an approach will provide valuable knowledge and understanding needed to inform and take actions across landscape settings, forest context, and socio-environmental conditions.
