Genomic variation in a widespread Neotropical bird (Xenops minutus) reveals divergence, population expansion, and gene flow [PDF]

open access: yes(2015) Molecular Phylogenetics and Evolution 83: 305-316, 2014
Elucidating the demographic and phylogeographic histories of species provides insight into the processes responsible for generating biological diversity, and genomic datasets are now permitting the estimation of histories and demographic parameters with unprecedented accuracy.

Assessing the Impact of Chemical Algae Management Strategies on Anurans and Aquatic Communities

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 1, Page 213-224, January 2023., 2023
Abstract Pond management with chemical and biological agents that reduce overgrowth of algae is an important means of maintaining water quality in residential ponds, yet the effects on nontarget species are not fully understood. We assessed the impact of Aquashade (a common nontoxic pond dye) and copper sulfate (a toxic algaecide) on American toad ...

Are standard aquatic test species and methods adequate surrogates for use in environmental risk assessment of pesticides in tropical environments?

open access: yesIntegrated Environmental Assessment and Management, Volume 19, Issue 1, Page 202-212, January 2023., 2023
Abstract In regulatory risk assessment, surrogate species of fish, aquatic invertebrates, and primary producers are tested to assess toxicity and subsequently the risk of pesticides to freshwater biota. This study evaluates whether the standard, surrogate test species (mostly temperate in latitudinal distribution) used in many parts of the world are ...

Development of single nucleotide polymorphism markers and genetic diversity in guava (Psidium guajava L.)

open access: yesPLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 58-69, January 2023., 2023
There are many understudied fruits of great economic and productive importance for regional agricultural hubs. Guava is an American fruit species with attractive nutritional and adaptability characteristics. However, in many countries like Mexico, its cultivation is still limited to small‐to‐medium size plantings and home gardens and depends on poorly ...

Neglected plant parasites: Mitrastemonaceae

open access: yesPLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 5-13, January 2023., 2023
Mitrastemonaceae are a remarkable family of parasitic flowering plants. The two species that make up this family have a disjunct distribution and a peculiar appearance. Both are devoid of roots, stems, and regular leaves and live inside the roots of their host plants for most of their life cycle.

Comparative wood anatomy and origin of woodiness in subfamilies Secamonoideae and Asclepiadoideae (Apocynaceae)

open access: yesTAXON, Volume 71, Issue 6, Page 1230-1250, December 2022., 2022
Abstract The Apocynaceae subfamilies Secamonoideae and Asclepiadoideae have undergone several transitions during their evolution with regard to growth form and degree of woodiness. In this study, we present a wood anatomical overview of both subfamilies that complements previous work on the remaining Apocynaceae.

Physics-based model to predict the acoustic detection distance of terrestrial autonomous recording units over the diel cycle and across seasons: insights from an Alpine and a Neotropical forest [PDF]

open access: yes, 2022
1. Passive acoustic monitoring of biodiversity is growing fast, as it offers an alternative to traditional aural point count surveys, with the possibility to deploy long-term acoustic surveys in large and complex natural environments. However, there is still a clear need to evaluate how the frequency-and distancedependent attenuation of sound as well ...

Phylogenomics and generic limits of Dypsidinae (Arecaceae), the largest palm radiation in Madagascar

open access: yesTAXON, Volume 71, Issue 6, Page 1170-1195, December 2022., 2022
Abstract With 178 species, palm subtribe Dypsidinae is one of the largest plant radiations on Madagascar. A well‐resolved species‐level phylogeny is required not only to unpick the drivers of this spectacular radiation, but also to define natural and useful generic limits in this taxonomically difficult group.

Biogeographical patterns of the neotropical genus Battus Scopoli 1777 (Lepidoptera Papilionidae) [PDF]

open access: yes, 1993
A phylogenetic approach to the groups of species of the neotropical Troidines currently included in the genus Battus Scopoli 1777 has been conducted. In the light of historical and ecological processes of evolution in the neotropical biota, the cladogram
