A hierarchical model about the building conceptions of stakeholders is proposed.

The model mechanism is based on bottom-up and top-down processes.

Unidirectional influence of scientist to other actors is clear in the literature.

Focus mainly on exchange of knowledge and not about social practices and values.

Collaborative actions may overcome these challenges and enhance decision-making.

Monitoring is a challenge for assessing targets for biodiversity agendas.

Biomonitoring systems can be linked in a network structure.

Biomonitoring initiatives in Brazil usually lack a clear conceptual framework.

The Network of Networks approach can promote the articulation of biomonitoring iniciatives.

We simulate different levels of extinctions of fishes following Mariana disaster.

We asked how extinctions lead to shifts in taxonomic and functional beta-diversity.

Simulations point to taxonomic subtractive heterogenization after the disaster.

For functional beta-diversity, functional homogenization prevails.

The contribution of nestedness increased for taxonomic and functional beta diversity.

Cats & rodents are widely introduced and damaging mammals on islands around the world.

Eradication is possible on uninhabited small to medium but not inhabited large islands.

Management on inhabited islands focuses on agriculture, livelihoods and animal welfare.

Reticence to management leads to conservation inaction & ultimately biodiversity loss.

Fernando de Noronha shows the conflict in cat and rodent management on inhabited islands.

Lead contamination is a worldwide problem that affects the health status of a great variety of bird species.

There is little information about lead contamination in bird species from South America.

Our revision suggests that lead contamination in birds may be a continental-scale threat.

Ammunition could be an underestimated lead source for South American birds.

It is important to implement the progressive lead ammunition banning in South America.

High-resolution remote sensing data reveals 28%, or 32 million hectares (Mha), of native vegetation cover in the Brazilian Atlantic Forest.

There are 7.2Mha of degraded riparian areas, of which 5.2Mha at least must be restored before 2038 by landowners for legislation compliance.

Restoring this existing legal debt could increase native vegetation cover in the biome up to 35%.

The median gap crossing ability is only 150m for forest specialist species.

The majority of the Brazilian Atlantic Forest comprises small isolated populations.

Expand on existing connected areas to improve functional connectivity effectively.

There are 287 species of aquatic plants commercialized in Brazilian e-commerce, distributed in 58 families.

There are 188 exotic species reported, 51 comes from Oriental region.

Several advertised species are recognized as highly invasive for many parts of the world.

Although Brazil presents adequate laws for exotic species trade, e-commerce of aquatic plants works fully even on the fringes of the law.

Dogs are not resident, invading the area from surrounding areas.

Domestic dogs are distributed in the whole area with 0.74–1.37individuals/km2.

Distance from Park's limits or presence of paved roads do not affect dogs’ occurrence.

Dogs’ activity was diurnal and native animals with the same pattern would probably be more susceptible to dog's impacts.

Management strategies should consider the engagement of local people to be successful.

Pond systems provide essential and unique landscape functions.

Unsustainable policies threaten to collapse pond functions in Brazil.

Emergency measures are necessary to prevent pond extirpation.

Brazil needs a national policy for wetland conservation.
