Functional diversity of snakes is explained by the landscape composition at multiple areas of influence

open access: yesEcology and Evolution, Volume 13, Issue 7, July 2023., 2023
This study investigated the impact of roads and landscape composition on the functional diversity of snakes in the Orinoco region of Colombia. The results suggest that landscape composition affects the functional diversity of both road‐killed snakes and those inhabiting the adjacent vegetation within an area of influence ranging from 250 to 2000 m.

COVID‐19 and income profile: How communities in the United States responded to mobility restrictions in the pandemic's early stages

open access: yesRegional Science Policy &Practice, Volume 15, Issue 3, Page 541-558, April 2023., 2023
Abstract Mobility interventions in communities play a critical role in containing a pandemic at an early stage. The real‐world practice of social distancing can enlighten policymakers and help them implement more efficient and effective control measures. A lack of such research using real‐world observations initiates this article.

Hummingbird diversity in a fragmented tropical landscape in the Chocó biogeographic zone

open access: yesBiotropica, Volume 55, Issue 2, Page 418-429, March 2023., 2023
We investigated habitat‐ and site‐level patterns of diversity, and community composition of hummingbirds between continuous forest (transects n = 16 in ~3500 ha) and more disturbed surrounding fragments (n = 39, 2.5–48.0 ha) in the Chocó rainforest of northwestern Ecuador. We found higher hummingbird species richness in forest fragments relative to the

From the ground up: Patterns and perceptions of herbaceous diversity in organic coffee agroecosystems

open access: yesEcological Solutions and Evidence, Volume 3, Issue 3, July–September 2022., 2022
Smallholder farms that transition to organic and biodiverse production are increasingly recognized as strongholds of agrobiodiversity. Yet the emergent herbaceous communities in these organic systems remain understudied, with the functional diversity and management of this stratum relatively unknown.

Complex landscapes stabilize farm bird communities and their expected ecosystem services

open access: yesJournal of Applied Ecology, Volume 59, Issue 4, Page 927-941, April 2022., 2022
Our results suggest that farmers can effectively manage their farms to harness ecosystem services from birds through farm diversification. Disservices provided by birds, however, appear to be most negatively impacted by landscape‐level complexity. Thus, greater incentives for farmers to increase semi‐natural cover at the landscape scale are likely ...

Process evaluation of the Disability Allowance programme in the Maldives

open access: yesInternational Social Security Review, Volume 75, Issue 1, Page 79-105, January/March 2022., 2022
Abstract Limited evidence on the design and implementation of social protection programmes for people with disabilities in low‐ and middle‐income countries constrains understanding of how their impacts could be improved. The Disability Allowance programme in the Maldives is a non means‐tested, monthly cash transfer targeting people with disabilities ...

Come Together, Right Now: Storylines and Social Identities in Coalition Building in a Local Policy Subsystem

open access: yesPolitics &Policy, Volume 49, Issue 5, Page 1216-1247, October 2021., 2021
How do social identities contribute to the formation of coalitions in a policy subsystem? Social identities help to understand the bundling of resources and common strategies for action. Thus, we argue that identification with a group and across groups discursively results in the formulation of shared and competing storylines.

Alterations in blood microbiota after colonic cancer surgery

open access: yesBJS Open, Volume 4, Issue 6, Page 1227-1237, December 2020., 2020
This study investigated changes in the amount of bacterial DNA in blood and the diversity of blood microbiota in the perioperative period in 30 patients undergoing minimally invasive surgery for colonic cancer. DNA encoding the bacterial 16S ribosomal RNA gene (16S rDNA) was found in whole blood from these patients, and the amount of bacterial 16S rDNA

Complex and nonlinear climate‐driven changes in freshwater insect communities over 42 years

open access: yesConservation Biology, Volume 34, Issue 5, Page 1241-1251, October 2020., 2020
Abstract The ongoing biodiversity crisis becomes evident in the widely observed decline in abundance and diversity of species, profound changes in community structure, and shifts in species’ phenology. Insects are among the most affected groups, with documented decreases in abundance up to 76% in the last 25–30 years in some terrestrial ecosystems ...

Sobre la uniformidad de las tarifas óptimas

open access: yesEnsayos Económicos, 1981
El propósito del trabajo es extender el análisis tradicional de la tarifa óptima. La primera sección presenta el estudio tradicional Marshalliano sobre tarifas óptimas que Johnson realizara en los años 1950. La segunda sección extiende el análisis anterior a un mundo de “n” bienes comerciados incluyendo impuestos y subsidios a las exportaciones e ...
