The distribution and conservation of areas with microendemic species in a biodiversity hotspot: a multi-taxa approach

Background

Microendemic species are species with very small geographic distributions (ranges). Their presence delimitates areas with microendemic species (AMs), denoting a spatial unit comprising at least one population of at least one microendemic species. AMs are assumed to be distributed distinctively and associated with specific ecological, historical, and anthropogenic attributes. However, the level of influence of these factors remains unclear. Thus, we studied the distribution patterns of microendemic species within the Brazilian Atlantic Forest to (a) identify the region's AMs; (b) evaluate whether ecological (latitude, altitude, distance from the coastline), historical (climate stability), and anthropogenic (ecological integrity) attributes distinguish AMs from non-AMs; and (c) assess the conservation status of the Atlantic Forest's AMs.

Methods

We mapped the ranges of 1,362 microendemic species of angiosperms, freshwater fishes, and terrestrial vertebrates (snakes, passerine birds, and small mammals) to identify the region's AMs. Further, spatial autoregressive logit regression models were used to evaluate whether latitude, altitude, distance from the coastline, Climate Stability Index, and ecological integrity can be used to discern AMs from non-AMs. Moreover, the AMs' conservation status was assessed by evaluating the region's ecological integrity and conservation efforts (measured as the proportion of AMs in protected areas).

Results

We identified 261 AMs for angiosperm, 205 AMs for freshwater fishes, and 102 AMs for terrestrial vertebrates in the Brazilian Atlantic Forest, totaling 474 AMs covering 23.8% of the region. The Brazilian Atlantic Forest is a large and complex biogeographic mosaic where AMs represent islands or archipelagoes surrounded by transition areas with no microendemic species. All local attributes help to distinguish AMs from non-AMs, but their impacts vary across taxonomic groups. Around 69% of AMs have low ecological integrity and poor conservation efforts, indicating that most microendemic species are under threat. This study provides insights into the biogeography of one of the most important global biodiversity hotspots, creating a foundation for comparative studies using other tropical forest regions.

Science and environmental policy establishment: the case of the Forest Act in the State of São Paulo, Brazil

Abstract Natural ecosystems are under severe threat worldwide and environmental policies are essential to minimize present and future impacts on biodiversity, ecosystem services and climate change. The New Forest Act in Brazil is the main policy to protect native vegetation in private lands, which comprise 54% of the remaining Brazilian native vegetation. However, conflicts between environmental and agricultural concerns in its implementation demand for balanced solutions based on scientific evidence. To face the challenge of applying science in environmental policy establishment, we developed a scientific project funded by the São Paulo State Research Foundation (FAPESP) to support the implementation of the New Forest Act in São Paulo State, as part of the Biota/FAPESP Program. The project was conducted differently from a regular research project: the broad objective was to provide scientific support to the State’s implementation of the New Forest Act, based on a participatory interaction among stakeholders to build specific objectives, methods, and discussion of results, within an interdisciplinary and intersectoral research team. Here, we present the lessons learned during and after the four years of the research project development to evaluate how scientific knowledge can be produced and adopted in the implementation of a specific environmental policy. We present the main outcomes and the challenges faced in trying to include scientific data in the decision-making process. We also present current and future challenges in the New Forest Act implementation that could be solved with scientific evidence. The lessons learned showed that even designing the project in order to meet the needs to support the implementation of the environmental policy, avoiding difficulties normally pointed out by similar projects, there was a great difficulty for scientific contributions to be adopted in the decision-making process. Most of the scientific information and advice, even after discussion and common understanding among a diverse stakeholder group, were ignored or over-ruled in the final decision-making phases.

Protected areas and unpaved roads mediate habitat use of the giant anteater in anthropogenic landscapes

The drastic reduction of the Brazilian Cerrado has transformed this savanna hotspot into vast swaths of commodity-based agriculture fields, mainly soybean, sugarcane, and beef-production pasturelands. The resulting habitat loss and fragmentation are the principal factors underlying population decline of native species inhabiting the Cerrado, particularly those with a high demand for space, low population density, and specialized diet, such as the endangered giant anteater (Myrmecophaga tridactyla). Although the species has been studied in protected areas, we know much less about its ability to endure in disturbed landscapes. Here, we analyzed camera-trapping data to estimate a proxy of habitat use (ψ^; occupancy) and detection probabilities of the giant anteater, identifying environmental covariates influencing these parameters in landscapes with intensive agriculture and commercial forestry. We found this species using about half of the study area (model average ψ^ = 0.51, CI = 0.40–0.62), with two predictors strongly influencing habitat use: protected areas and unpaved roads. In turn, detection probability correlates positively with area of open Cerrado and negatively with area of settlements. The species is more likely to use unpaved roads inside protected areas (ψ^ = 0.90, CI = 0.47–0.75), compared to off road sites in the surrounding areas (ψ^ = 0.19, CI = 0.10–0.34). Our findings indicate that giant anteaters are dependent on nature reserves and native vegetation areas existing on private properties, whose protection is regulated by the Brazilian Native Vegetation Protection Law. Given the relative paucity of state-owned protected areas in the Brazilian Cerrado, increasing the adherence of rural owners to this law is, therefore, key for the conservation of the giant anteater. The intense use of unpaved roads might reflect travelling and/or foraging optimization, a behavioral response that, nevertheless, may compound this species’ susceptibility to suffer mortality from roadkill.

Who Owns REDD+? Carbon Markets, Carbon Rights and Entitlements to REDD+ Finance

The question of who is entitled to benefit from transactions under the United Nations framework to reduce emissions from deforestation and forest degradation (REDD+) remains one of the most controversial issues surrounding cooperative efforts to reduce deforestation in developing countries. REDD+ has been conceived as an international framework to encourage voluntary efforts in developing countries to reduce greenhouse gas emissions and enhance carbon removals from forest activities. It was designed as an international framework under the United Nations Framework Convention on Climate Change (UNFCCC) to enable the generation of emission reductions and removals (ERRs) at the national—and, provisionally, the subnational—level and is, thus, primarily a creature of international law. However, in defining forest carbon ERRs, the international framework competes with national emission trading systems and domestic REDD+ legislation as well as private standards that define units traded on the voluntary carbon market. As results-based and carbon market systems emerge, the question remains: Who can claim participation in REDD+ and voluntary carbon market projects? The existence of different international, national and private standards that value ERRs poses a challenge to countries that participate in REDD+ as well as to communities and private actors participating in voluntary carbon market projects. This paper seeks to clarify the nature and limitation of rights pertaining to REDD+ market transactions. It also links the notion of carbon rights to both carbon markets and government’s decision on benefit sharing. Applying a legal lens, this paper helps to understand the various claims and underlying rights to participate in REDD+ transactions and addresses ambiguities that can lead to conflict around REDD+ implementation. The definition of carbon rights and the legal nature of carbon credits depend on local law and differ between countries. However, by categorizing carbon rights, the paper summarizes several legal considerations that are relevant for regulating REDD+ and sharing the financial benefits of transacting ERRs.
