Critical Analysis of a Peer Reviewed Source: “Effects of climate change and habitat loss on a forest-dependent bee species in a tropical fragmented landscape”
This peer reviewed journal article, “Effects of Climate Change and Habitat Loss on a Forest-Dependent Bee Species in a Tropical Fragmented Landscape”, was written by André Nemésio, Daniel P. Silva, João Carlos Nabout, and Sara Varela in March, 2016 for Insect Conservation & Diversity. I found this article through the Hollins University library database, EBSCOhost. This is a very reliable source because it is a peer reviewed article. Also, the authors are affiliated with the Universidade Federal de Uberlândia, Instituto Federal Goiano, Universidade Estadual de Goiás, Universidad de Alcalá, and the Leibniz Institute for Evolution and Biodiversity Science.
To summarize, the journal article talks about the effect climate change and a plethora of other issues are having on the local bee populations in the Atlantic Forests of Brazil. The abstract states: “1. Climate change and deforestation are suggested to be the main drivers of decline in pollinators. Forest-dependent species are expected to be the most affected and Euglossa marianae Nemesio (Hymenoptera: Apidae), an endemic species of the highly fragmented Brazilian Atlantic Forest (AF), is believed to be declining as a consequence of human impact. 2. Over the last 17 years, we carried out ﬁeld surveys to unveil its distribution, allowing us to investigate the potential effects of global climate change on this species, from the last glacial maximum into the future, using species distribution models. Our main goals were to: (i) identify populations potentially under risk of extinction given future climate change; (ii) quantify the amount of climatically suitable and climatically stable areas for E. marianae within AF; (iii) evaluate the area that are available as natural habitat and under legal protection, in an attempt to indicate priority areas to preserve this species. 3. The most stable areas for maintaining populations of E. marianae were located in southern Bahia and northern Espiırito Santo states, a region severely affected by deforestation and with several protected areas. Climate change per se does not seem to be the major problem for E. marianae. It may constitute an indirect problem given the limited dispersal abilities of this species, however. 4. Climatically suitable areas will probably increase southwards in the future, but the extreme fragmentation of AF adds great uncertainty as to whether the species will disperse southwards, to regions such as the ‘Serra do Mar’ in northeastern Sao Paulo”.
The Atlantic Rain Forest of Eastern Brazil is one of the most threatened tropical biomes. Barely ten percent of the original forest remains. So, the conservation status of the bee species in this forest deserves extra attention. Some of the bee species there have already gone extinct due to habitat loss. The bees are vital for the survival of the Atlantic forests and for Eastern Brazil. Though the tested bee species proved to be highly adaptable to climate change, its effects will cause habitat loss, preventing the bees from travelling from one area to another, trapping them and eventually eliminating them. Bee’s must be protected, not just here in the U.S., but everywhere, especially places like here in the Global South where habitats have been destroyed.
