Perspectives in Ecology and Conservation (PECON) is a scientific journal devoted to improving theoretical and conceptual aspects of conservation science. It has the main purpose of communicating new research and advances to different actors of society, including researchers, conservationists, practitioners, and policymakers. Perspectives in Ecology and Conservation publishes original papers on biodiversity conservation and restoration, on the main drivers affecting native ecosystems, and on nature¿s benefits to people and human wellbeing. This scope includes studies on biodiversity patterns, the effects of habitat loss, fragmentation, biological invasion and climate change on biodiversity, conservation genetics, spatial conservation planning, ecosystem management, ecosystem services, sustainability and resilience of socio-ecological systems, conservation policy, among others.
Perspectives in Ecology and Conservation is the official scientific journal of the Brazilian Association for Ecological Science and Conservation. It is an open access journal, supported by the Boticário Group Foundation for Nature Protection, and thus without any charge for authors. Perspectives in Ecology and Conservation was previously published, between 2003 and 2016, as 'Natureza & Conservação'.

A country-level database of useful native plants is provided.
- •
Plant families with high species richness have a high number of useful species.
- •
Plant species with great cultural importance are frequent in the landscape.
- •
70% of useful native plant species are used exclusively in one region.
- •
Differences in the plants used reflect the biogeographical affinities between regions.

- •
Irrespective of severity, fire reduces forest taxonomic and functional α and β diversity.
- •
Fire filtered species with similar functional traits and thus increases functional homogeneity.
- •
Resprouting capacity and leaf phenology (deciduousness) are two key traits that enhance post fire tree survival.
- •
Fire decreases the diversity and abundance of plants dispersed by animals.
- •
Fire uncouples the dominant functional traits between mature surviving trees and the seedlings that regenerate.

- •
Secondary and old-growth subtropical Brazilian Atlantic Forests are acting as carbon sink.
- •
Biodiversity is not related to net carbon change in this region.
- •
Subtropical Brazilian Atlantic Forests should be conserved irrespective to their ages to maintain carbon sink.
- •
Biodiversity and carbon-related processes should be taken as conservation targets.

- •
Protecting further 6.75% of the Cerrado doubles representation of endemic tetrapods.
- •
Larger priority areas for conservation are concentrated in northern Cerrado.
- •
Small and m edium priority areas are scattered across southern Cerrado.
- •
Our ability to represent endemic terrestrial vertebrates decreased with recent habitat loss.
- •
Habitat loss precludes the representation of tetrapods in large top priority areas.

- •
Not all invasive grasses would be equally affected by climate change.
- •
Range retractions are projected for some species regardless of the scenario.
- •
We expect species niches to shift to areas not yet occupied.
- •
Arundo donax had the greatest range expansion in the SSP3 and SSP5 scenarios.

- •
Forest loss leads to decline in tree species richness.
- •
Species richness is effective for recording biodiversity responses to deforestation.
- •
Extinction debt might not be masking long-term effects of deforestation.
- •
High conservation value of disturbed forests, in terms of evolutionary history.
- •
Disturbed forests are partly maintaining ecosystem function now, and in the future.

- •
Damage costs from biological invasions and natural hazards are of similar magnitude.
- •
Global biological invasion costs increased by 702% from 1980–1999 to 2000–2019.
- •
Invasion costs increased faster than natural hazard damages over time (1980–2019).

- •
The role of intraspecific variation across levels of biological organization is an unanswered question in invaded and non-invaded pollination networks.
- •
Significant intraspecific variation was detected in the pollen loads and pollen deposition of the invasive plant Impatiens glandulifera.
- •
Only a few individual pollinators carried large amounts of alien pollen grains, potentially function as super-spreaders driving the invading process.
- •
Node and structural specialization were higher for individual-based and pollen-transfer networks in comparison to species-level and pollen-transport networks.
- •
These findings shed light on the mechanisms of the (re)organization of population niches and the invasion biology dynamics scaling-up to community and ecosystem functioning.

- •
We extracted hummingbird-plant data from an online photograph platform.
- •
Data were compared with expert collected data, available in the literature.
- •
There were some similarities between citizen and expert data.
- •
For the hummingbirds, overlap in plant species interacting was generally low.
- •
Unstructured citizen science data can be a rich source of interaction information.

- •
We identified 52 community-based monitoring projects on game terrestrial fauna in the tropics.
- •
Most of these initiatives (86%) were interrupted due the lack of funding.
- •
The absence of spatio-temporal data analyses prevented the provision of information on monitored resource.
- •
The empowerment and management actions were hampered by the lack of local participation.
- •
Community-based approaches will be more efficient if they engage local people at all stages of the monitoring.

- •
Diel activity of 45% of birds and 36% of mammals assessed significantly changed in areas with higher human pressures.
- •
In general Mammals became more nocturnal, while birds became more diurnal.
- •
For birds increased diurnality may not be strongly associated with direct human pressures like hunting, and instead with habitat disturbance.
- •
Our results align with other studies that show increased nocturnality for mammals in areas with high human pressure.
- •
Opposing behavioural responses to humans among vertebrates have repercussions for intraguild predation, competition and conservation considerations.

- •
Forest cover decreases primate species richness in the Amazon and Atlantic forest.
- •
Amazon primates are more sensitive to forest loss than Atlantic forest species.
- •
Species in more deforested landscapes have small home ranges.
- •
Non-linear models fitted the data better than linear models.
- •
We must maintain forest cover above 60% to prevent primate extinctions.
