Outreach and education on conservation issues are crucial elements of successful conservation programmes. Big screen animations have a global reach, yet are not fully capitalised by conservationists and there remains great potential in developing them into powerful biodiversity and conservation education outreach tools despite known shortfalls and limitations in scientific value. We reviewed recent major animated features with multiple conservation themes (e.g. extinction, wildlife trade, ex-situ conservation) and that especially feature tropical biodiversity, especially endemics, charismatic flagships or threatened species in authentic natural settings. We acknowledge that while the potential to develop them into effective biodiversity and conservation education tools is undoubted and there are recent examples, there is a crucial need to complement them with supporting educational materials, campaigns and activities. Partnerships between the animation studios, conservation NGOs and local stakeholders will be integral to effect this.

Emerging international standards for Reduced Emissions from Deforestation and Degradation (REDD) projects require a demonstrated biodiversity benefit and a biodiversity monitoring protocol. Guidance for an acceptable protocol is proposed specifically for tropical forests, focusing on technologies that are widely available, rigorous, and aimed at important indicator taxa for forest function. Two techniques, camera trapping for large and mesoscale mammals and acoustic monitoring for bats, are proposed as current technologies that meet the criteria for a model biodiversity monitoring protocol for REDD projects.

REDD+ may see billions of dollars paid to developing countries to improve forest management. This could potentially provide co-benefits for biodiversity conservation. Whilst this issue has been assessed several times in the existing literature, biodiversity itself has tended to be treated as homogenous. Here we propose a new framework in which to disaggregate and assess potential biodiversity beneficiaries of REDD+: pleiotropy and charisma. Pleiotropy describes the dependence of a species' conservation status on habitat loss alone. Pleiotropically-linked species are threatened principally by forest loss and are most likely to benefit from activities such as reduced deforestation. Non-pleiotropically-linked species are also threatened by other processes such as hunting, and will require extra funding outside REDD+ such as premium payments for their conservation. Charisma describes the degree to which species may be able to generate premiums. We consider that the incorporation of these two dimensions into the REDD+ debate will facilitate a more nuanced discussion of biodiversity co-benefits amongst researchers and other stakeholders than has so far been the norm.

Brazil is the world largest producer of sugarcane ethanol, an alternative to gasoline. Large players, including international oil companies, are aware of the potential of Brazilian ethanol and are investing in the production and expansion of sugarcane plantations in the country. The growing ethanol market imposes some conservation challenges on Brazil to meet the increasing demand. The market points out to an expansion of sugarcane crops, but this can be extremely harmful to the remaining biodiversity of the Brazilian Atlantic Forest. The impact of such expansion will be more severe in the states of Alagoas, Pernambuco, Paraíba and Rio Grande do Norte, the second largest sugar-ethanol production region, and one of the most globally threatened areas of tropical forest (only 12% left, ∼ 1% legally protected). There, most forest fragments are smaller than 100 ha and several endemic species are on the verge of extinction. Here we advocate that instead of expanding plantations, increasing crop productivity should be the more logical and environment-friendly solution for that region. Further, we indicate that the current challenge is to increase the number of sugar and ethanol companies following best management practices and to turn these programs into a real opportunity to restore the biodiversity and environmental services of an ecosystems in eminent collapse. We urge that companies should move one step further and, at least, guarantee the protection of the habitats that go beyond the protection area imposed by the current environmental law.

Seasonally dry tropical forests (SDTFs) provide a habitat for a diverse number of species and cover significant land areas. Yet, the amount of scientific research they have attracted is minimal. Recently, an international debate on the generality, consequences and forces keeping SDTFs in a position of relative negligence has begun. This paper assesses and compares biodiversity-related knowledge across the major Brazilian ecosystems to verify in which extent the Caatinga vegetation (a mosaic of scrubs and patches of seasonally dry forest) has been scientifically unappreciated. In fact, Caatinga attracted the lowest scores from semi-quantitative indexes describing biodiversity-survey efforts and knowledge status, with a negligible number of papers published internationally. Caatinga also supports fewer research teams and senior researchers as compared to humid tropical forests (Amazonia and Atlantic Forest). Both the knowledge index and number of published papers were explained by a model combining ecosystem area (km²), inventory index plus the current number of research teams or senior researchers assigned to Brazilian ecosystems. These findings reinforce the notion that SDTFs have experienced lower scientific efforts, but also reveal an apparent connection between institutional capacity, production/accumulation of scientific knowledge and conservation efforts. Although the research agenda for reconciling land-use and biodiversity conservation has been launched, current institutional anemia across SDTFs is likely to limit its impacts and achievements.

Tropical deforestation is occurring at an alarming rate. The loss of these forests contributes significantly to total global carbon dioxide emissions and accelerating rates of climate change; moreover, many deforested lands lose fertility and are abandoned. Demands to protect biodiversity and reverse climate change call for efforts to reforest such lands, and one method is through fire control, as fire suppresses tree regeneration. Unfortunately, the success of fire control is often not known for tropical regions because research efforts must span decades. We compared above ground biomass in two plots of regenerating forest that were protected from fire for 12 and 32 years in Kibale National Park, Uganda. Tree biomass of the plots was substantial, and while the biomass of the 12- and 32-year plots did not differ significantly, the 12-year plot had a higher biomass in the small diameter classes in comparison to the 32-year plot. Twenty-four tree species were growing in 12-year plot, while 46 grew in the 32-year plot. We conclude that fire exclusion is a promising approach for tropical forest restoration, and we demonstrate that it is cost-effective relative to programs that plant tree seedlings.

Succession in the Brazilian Amazon depends on prior land-use history. Abandoned clearcuts become dominated by Cecropia trees and exhibit species replacements characteristic of natural succession in forest lightgaps. In contrast, abandoned pastures are dominated by Vismia trees that inhibit natural succession for a decade or more. Here we explore how advance regeneration and limited seed dispersal may contribute to the arrested succession in Vismia-dominated stands. Vegetation surveys showed that every Vismia stem in 3–8 year old Vismia stands originated as a re-sprout. In Cecropia stands, all tree species, including Vismia, originated mostly from seeds, after deforestation and abandonment. The 100% re-sprouts of Vismia in the abandoned pastures confirms that Vismia dominance results from re-sprouting following pasture fires. Seed rain in both Vismia and Cecropia dominated stands was limited almost exclusively to second growth species already reproducing in those stands, suggesting that the bats and birds foraging there were not bringing mature forest seeds into the second growth, but simply feeding and depositing local second growth species. As dispersal was similar in both stand types, dispersal differences cannot account for the ongoing dominance of Vismia relative to the ongoing successional transitions in Cecropia stands. Overall, advance regeneration in the form of Vismia re-sprouts is much more likely to be the driver of Vismia dominated succession than differential dispersal of mature forest seeds. In order to avoid extensive forest conversion into unproductive Vismia wastelands in the Amazon Basin, forestry permits for harvesting timber should include restrictions on subsequent anthropogenic degradation, such as conversion to pasture and prescribed burning.

From June, 2007, to February, 2009, the Waria Valley Community Conservation and Sustainable Livelihoods Project (WVCP) completed an inventory survey of the birds of the lower Waria Valley, Morobe Province, Papua New Guinea. Four land use types – agricultural, secondary forest edge, primary forest edge and primary forest – were surveyed using Mackinnon list surveys. In total, 125 species representing 43 families were identified, of which 54 (43.2%) are endemic to the islands of New Guinea and the Bismark Archipelago. The avifauna of primary forest edge and primary forest was more species rich and diverse than that of agricultural habitats. Agricultural habitats also differed significantly in both overall community composition and some aspects of guild composition compared to all three forested habitats. Nectarivores and insectivore-frugivores formed a significantly larger proportion of species in agricultural habitats, whereas obligate frugivores formed a significantly greater proportion in forested habitats. We propose further survey and management initiatives that could help contribute to the conservation and sustainable use of the area's important biological resources.

Patterns of carbon retention and distribution across human-modified landscapes have been poorly investigated. In this paper carbon distribution across three forest habitats of a fragmented Atlantic forest landscape in northeast Brazil is examined. Data on tree assemblages (DBH ≥10 cm) inhabiting forest interior stands, forest edges and fragments (2.05–365 ha) were obtained via information from 59 0.1-ha plots (a total of 4,845 stems and 198 tree species), and it was further incorporated in four allometric equations for estimation of above-ground biomass and carbon. Stocks of carbon were highly variable within habitats of Serra Grande, but forest interior plots retained almost three times more carbon (202.8 ± 23.7 TonC/ha) than edge and fragment plots, while these edge-affected habitats exhibited similar scores. Moreover, emergent tree species accounted for the majority of the carbon retained (59.13%) in interior plots with understorey species playing a minor role. However, carbon retained by emergent species decreased by a half across forest edges and forest fragment since large stems (> 70 cm DBH) and very tall trees (> 31 m height) were very rare in these habitats. Finally, a forest cover mapping revealed the occurrence of 213.19 km² of forest interior habitat in the whole Atlantic forest of northeast Brazil. This figure means that only 8% of total remaining forest habitat has a full potential for carbon storage, with the other 92% (edge-affected habitats) storing just a half of that. Our results suggest that habitat fragmentation and the consequent establishment of edge-affected habitats (forest edges and fragments) drastically limit forest capacity for carbon storage across human-modified landscapes since the loss of carbon due to reduced abundance of large trees is not compensated by either canopy or understorey species.

The endemic Coffea kihansiensis was monitored in the Kihansi gorge over a three year period following diversion of the Kihansi River underground for hydropower production and its associated catastrophic effect on the gorge biota. We assessed the growth status of the coffee population by measuring, along an altitudinal gradient, the height and diameter of 450 randomly selected coffee stems in 18 sampling plots covering ca 1800 m². We also collected microclimatic data to compare with that collected prior to river diversion. Coffee infestation by parasites was examined by recording the number of stems with signs of infestation. There was no significant change in size of Coffea kihansiensis during the study period. However, the size for immature plants differed between the two sites; LWF and UCF. Parasite infestation differed between reproductive age classes and was greater at lower elevation (800 – 850 m a.s.l) than above, suggesting possible effects of altitude and microclimate on coffee infestation. Increasing habitat degradation, parasite infestations, and loss of the species' ecological envelope seriously undermine the species' growth potential with severe consequences for its long-term population survival. Continued monitoring of the species is recommended, with the emphasis on understanding basic species biology, population trends, and the potential role of assisted migration in saving the population from collapse.
