Integrating adult occurrence and reproduction data to identify conservation measures for amphibians

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life‐history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider ...

Dependencia de la densidad en los ánades norteamericanos [PDF]

, 2004
The existence or otherwise of density dependence within a population can have important implications for the management of that population. Here, we use estimates of abundance obtained from annual aerial counts on the major breeding grounds of a variety ...

Scaling up ocean conservation through recognition of key biodiversity areas in the Southern Ocean from multispecies tracking data

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Biodiversity is critical for maintaining ecosystem function but is threatened by increasing anthropogenic pressures. In the Southern Ocean, a highly biologically productive region containing many endemic species, proactive management is urgently needed to mitigate increasing pressures from fishing, climate change, and tourism.

La sombra alargada del patrón: Gamonalismo y hábitos hacendatarios en Chimborazo tras la reforma agraria

The Journal of Latin American and Caribbean Anthropology, Volume 29, Issue 4, Page 352-363, December 2024.
Abstract This paper explores selective aspects of the historical processes of organization of the kichwa peasantry in the Andes of Ecuador. Based on the analysis of two representative cases of confrontation between peasants and landowners over access to land in the province of Chimborazo, it discusses the relevance of the concept of “gamonalismo” as ...

Sequencing vs. amplification for the estimation of allele dosages in sugarcane (Saccharum spp.)

Applications in Plant Sciences, Volume 12, Issue 5, September-October 2024.
Abstract Premise Detecting single‐nucleotide polymorphisms (SNPs) in a cost‐effective way is fundamental in any plant breeding pipeline. Here, we compare three genotyping techniques for their ability to reproduce the allele dosage of SNPs of interest in sugarcane (Saccharum spp.).
