Landscape factors and allochthonous congeneric species influence Callithrix aurita occurrence in Brazilian Atlantic Forest remnants. [PDF]

open access: yesEcol Evol, 2023
Callithrix aurita is isolated in forest fragments surrounded by potentially inhospitable matrices, along with the proximity of a more generalist and invasive species, thereby increasing the possibility of introgressive hybridization. The approach used here can be applied to improve conservation studies of other endangered species, such as C. flaviceps,

First Record of Mating Involving a Melanistic Jaguar (<i>Panthera onca</i>) in the Wild: Novel Behavioural Insights Into Colour Morphs and Captive-Wild Comparisons. [PDF]

open access: yesEcol Evol
We report the first scientifically documented copulation event between a melanistic and wild‐type jaguar (Panthera onca) in the wild, captured via remote camera in the Brazilian Amazon. The observed behaviours closely mirror those seen in captive jaguars, providing preliminary insights into the effects of melanism and captivity on jaguar mating ...

Caatinga diaspores: Descriptive overview of dispersal units of seasonally dry tropical forests and woodlands. [PDF]

open access: yesEcology
Abstract Dispersal unit characteristics provide crucial insights into species ecology and are essential for the conservation and restoration of ecosystems. The Caatinga, the largest ecosystem of seasonally dry tropical forests and woodlands in South America, remains underrepresented in terms of dispersal unit data, which are often scattered across the ...

Development of a SNP Panel for Geographic Assignment and Population Monitoring of Jaguars (<i>Panthera onca</i>). [PDF]

open access: yesEcol Evol
We have developed a genome‐enabled single nucleotide polymorphism (SNP) panel for use in jaguar geographic traceability, individual identification, kinship, and sexing. Our panel, named “Jag‐SNP”, comprises 459 SNPs selected from an initial pool of 13,373,949 markers based on the inter‐biome FST, followed by rigorous filtering and addition of eight sex‐

From Herbarium to Landscape: New Records and Mapping Rare and Threatened Species of Brazilian Atlantic Rainforest. [PDF]

open access: yesEcol Evol
Botanical collections remain limited in the mountainous areas of the Brazilian Atlantic Rainforest, which compromises biogeographic knowledge of endangered and locally endemic species and many others that have not yet been described. These gaps hinder the accuracy of biodiversity indicators, limit the discovery and description of new species, restrict ...

Weight‐Length and Length‐Length Relationships of the Endangered Zebra Pleco Hypancistrus zebra (Siluriformes, Loricariidae) from the Xingu River, Amazon, Brazil

open access: yesJournal of Applied Ichthyology, Volume 2023, Issue 1, 2023., 2023
Hypancistrus zebra is a Loricariid endemic to a very limited stretch of the Xingu River and has a high value in the ornamental fish trade. The natural populations have experienced high fishing pressure since the late 80s and were recently impacted by the construction of the third largest hydroelectric dam complex in the world, the Belo Monte Project ...

Testing a global standard for quantifying species recovery and assessing conservation impact

open access: yesConservation Biology, Volume 35, Issue 6, Page 1833-1849, December 2021., 2021
Abstract Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species).

TRY plant trait database – enhanced coverage and open access

open access: yesGlobal Change Biology, Volume 26, Issue 1, Page 119-188, January 2020., 2020
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people.

In vitro conservation of Piper aduncum and Piper hispidinervum under slow-growth conditions

open access: yesPesquisa Agropecuária Brasileira, 2011
The objective of this work was to evaluate in vitro storage of Piper aduncum and P. hispidinervum under slow-growth conditions. Shoots were stored at low temperatures (10, 20 and 25°C), and the culture medium was supplemented with osmotic agents (sucrose
