Wayt; New York Botanical Gardens; wthomas@nybg.org; Davis, Frank; University of California, Santa Barbara; fd@bren.ucsb.edu.
Conservation in densely settled biodiversity hotspots often requires setting up reserve networks that maintain sufficient contiguous habitat to support viable species populations. Because it is difficult to secure landholder compliance with a tightly constrained reserve network design, attention has shifted to voluntary incentive mechanisms, such as purchase of conservation easements by reverse auction or through a fixed-price offer. These mechanisms carry potential advantages of transparency, simplicity, and low cost. However, uncoordinated individual response to these incentives has been assumed incompatible with the conservation goal of viability, which depends on contiguous habitat and biodiversity representation. We model such incentives for southern...

Government agencies that develop infrastructure such as roads, waterworks, and energy delivery often impact natural ecosystems, but they also have unique opportunities to contribute to the conservation of regional natural resources through compensatory mitigation. Infrastructure development requires a planning, funding, and implementation cycle that can frequently take a decade or longer, but biological mitigation is often planned and implemented late in this process, in a project-by-project piecemeal manner. By adopting early regional mitigation needs assessment and planning for habitat-level impacts from multiple infrastructure projects, agencies could secure time needed to proactively integrate these obligations into regional conservation objectives....

Evaluation of an ant sampling protocol (Hymenoptera: Formicidae) in three modified environments located inside an austral Atlantic Forest area of Brazil Ecología austral
Lutinski,Junir Antonio; Lutinski,Cladis Juliana; Iop,Samanta; Mello Garcia,Flávio Roberto.
This study evaluated the efficiency as a tool for ant survey of a sampling protocol composed of six methods, and examined the role of environmental features on the efficiency of methods complementarity . We applied them in three environments (pine, eucalyptus and native forest) in the National Forest of Chapecó and the effect of the characteristics of these environments on methods complementarity. The sampling methods were pitfall traps, two types of bait (sardines and glucose), sweep net, entomological umbrella and Malaise trap. The protocol efficiency of the protocol in the ant inventory was evaluated based on rarefaction curves, richness estimators and records of occurrence of ants. The protocol captured the greatest richness on native forest...

Erosion factors and magnetic susceptibility in differet compartments of a slope in Gilbués-PI, Brazil REA
Santos,Hélio L.; Marques Júnior,José; Matias,Sammy S. R.; Siqueira,Diego S.; Martins Filho,Marcílio V..
The erosion is the degradation of soil with effects on crop productivity and pollution of the environment. To understand the spatial variability of this phenomenon, geostatistical techniques and concepts of soil-landscape can be used to identify landscape compartments with different potential of erosion. The aim of this study was to understand the factors of erosion in landscape compartments and the relations with the magnetic susceptibility (MS) of the soils in a slope in Gilbués, state of Piauí (PI), Brazil. Sampling meshes were set in compartments I and II with 121 points and in compartment III with 99 points spaced every 10 meters. There was significant difference to erodibility (K) and risk of erosion (RE); the spatial variability of MS was lower than...

Additive effects of climate change on connectivity between marine protected areas and larval supply to fished areas ArchiMer
Andrello, Marco; Mouillot, David; Somot, Samuel; Thuiller, Wilfried; Manel, Stephanie.
AimTo study the combined effects of climate change on connectivity between marine protected areas (MPAs) and larval supply to the continental shelf. LocationThe Mediterranean Sea, where sea surface temperatures are expected to strongly increase by the end of the 21st century, represents an archetypal situation with a dense MPA network but resource overexploitation outside. MethodsUsing an individual-based mechanistic model of larval transport, forced with an emission-driven regional climate change scenario for the Mediterranean Sea, we explored the combined effects of changes in hydrodynamics, adult reproductive timing and larval dispersal on the connectivity among MPAs and their ability to seed fished areas with larvae. ResultsWe show that, over the...

Space invaders; biological invasions in marine conservation planning ArchiMer
Giakoumi, Sylvaine; Guilhaumon, Francois; Kark, Salit; Terlizzi, Antonio; Claudet, Joachim; Felline, Serena; Cerrano, Carlo; Coll, Marta; Danovaro, Roberto; Fraschetti, Simonetta; Koutsoubas, Drosos; Ledoux, Jean-batiste; Mazor, Tessa; Merigot, Bastien; Micheli, Fiorenza; Katsanevakis, Stelios.
AimBiological invasions are major contributors to global change and native biodiversity decline. However, they are overlooked in marine conservation plans. Here, we examine for the first time the extent to which marine conservation planning research has addressed (or ignored) biological invasions. Furthermore, we explore the change of spatial priorities in conservation plans when different approaches are used to incorporate the presence and impacts of invasive species. LocationGlobal analysis with a focus on the Mediterranean Sea region. MethodsWe conducted a systematic literature review consisting of three steps: (1) article selection using a search engine, (2) abstract screening and (3) review of pertinent articles, which were identified in the second...

Optimisation and the selection of conservation contracts AgEcon
Hajkowicz, Stefan; Higgins, Andrew J.; Williams, Kristen; Faith, Daniel P.; Burton, Michael P..
This paper explores alternative techniques for the selection of conservation contracts under competitive tendering programs. Under these programs, purchasing decisions are often based on the benefits score and cost for proposed projects. The optimisation problem is to maximise the aggregate benefits without exceeding the budget. Because the budget rarely permits all projects to be funded, there is a binary choice problem, known in the operations research published work as a knapsack problem. The decision-maker must choose which projects are funded and which are not. Under some circumstances, the knapsack problem can be unsolvable because computational complexity increases exponentially with the number of projects. This paper explores the use of several...

Mapping and evaluation of the state of conservation of the vegetation in and surrounding the Chapada Diamantina National Park, NE Brazil Biota Neotropica
Funch,Roy Richard; Harley,Raymond Mervyn; Funch,Ligia Silveira.
The Chapada Diamantina National Park (CDNP) was created in the midst of a densely populated area, and significant sections of the reserve are still undergoing processes of natural regeneration after intensive diamond mining activities were initiated in the mid-1800's. An up-to-date vegetation map was needed in order to indicate the types and distribution of regional vegetation assemblages in an easily interpretable manner and at an appropriate planning scale that could be easily consulted by decision makers and other interested groups at all levels of conservation (and development) planning. A vegetation map of the Chapada Diamantina National Park, and the areas immediately surrounding it, was prepared that: 1) delimits, describes, and maps the regional...

Coastal habitat mapping of Bahía Aguacate and bahía Cupica, northern Colombian Pacific coast Boletín de Investigaciones
Silvar,Paula; Giraldo,Alan.
ABSTRACT Colombian North Pacific region host a huge valuable ecosystem due to its particular conditions. Some of these sectors are isolated and pristine, with little research effort. When there is a limitation of economic resources, classification and basic mapping techniques of the intertidal and subtidal habitats allow the identification of distinct and representative areas of a region. Previous studies point out the zones of Cabo Marzo- Bahia Aguacate and Punta Cruces- Bahia Cupica as ecologically important areas, therefore the present study focus on habitat mapping these sites. To create the map, we develop a hierarchical classification of intertidal and subtidal habitats separately. In conclusion, Colombian North Pacific region is extremely...

Contribution of the Marine Protected Areas of the National Natural Park System to the ecosystems representativeness of Colombia Boletín de Investigaciones
Alonso C.,David; Corredor-Rubiano,Ivonne.
ABSTRACT An analysis of representativeness of marine and coastal ecosystems was carried out in the 18 Marine Protected Areas (MPAs) administered by the System of National Natural Parks of Colombia (SPNN) and their changes in 2020 compared to 2010. The Caribbean increased the representativeness of mangroves, seagrasses, sedimentary bottoms, and saline beaches. In the Pacific, estuaries representativeness, sedimentary bottoms, mangroves, intertidal mudflats, sandy beaches, and seamounts increased. Deep-sea corals were included as a new ecosystem for the SPNN. From the representativeness ranges determined for this analysis, it was found that the only ecosystem with no representativeness (0 %) (Deep-sea corals) became overrepresented (≥ 60 %). The number of...
