The importance of analysis method for breeding bird survey population trend estimates

open access: yes, 2009
Population trends from the Breeding Bird Survey are widely used to focus conservation efforts on species thought to be in decline and to test preliminary hypotheses regarding the causes of these declines. A number of statistical methods have been used to

The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Applying multi-mesh gillnet to monitor fish communities in neotropical rivers

open access: yesNeotropical Ichthyology
Neotropical fish diversity has been declining, driven by increasing human pressures. This accelerating loss underscores the urgent need for standardized methods capable of reliably monitoring these communities.

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Trials and tribulations of Neotropical plant taxonomy: Pace of tree species description

open access: yesPlants, People, Planet
Societal Impact Statement Given the current unprecedented concerns for global biodiversity loss, it is critical to identify best practices for describing new species more efficiently so we can complete the inventory of the Neotropical flora and implement

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

open access: yesWildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

A new Andean species of Ablabesmyia Johannsen from Colombia (Diptera: Chironomidae) with an updated taxonomic key for Neotropical species

open access: yes, 2019
Ablabesmyia is a speciose genus, with about 90 species distributed worldwide, 37 of which occurring in the Neotropical region. In Colombia, A. metica is the only species of the genus recorded so far, which was initially described with material collected ...

Temporal community change in stream ecosystems varies by assemblage across US climates

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.
