In this study, we use a mixed methods approach to analyze the conversational content and interactions constituting five family groups' visits to the Marine Aquarium of Rio de Janeiro (AquaRio), the ...largest marine aquarium in South America, to understand how families interact with science and construct meaning regarding science and conservation. The audiovisual records of the family groups were analyzed using categories that investigate the types of interactions and conversations that may take place in scientific‐cultural venues. The results suggest that, throughout the visits, family members were driven by their observation and contemplation of the animals on exhibit to interact with each other to share information about marine biodiversity and its conservation. The adults, children, and explainers all had fundamental roles in the construction of dialogues on scientific topics. The adults adopted behaviors that facilitated learning, made associations with previous experiences, read panels, and contextualized the information to their family's reality. The children were notable for their protagonism, asking questions, giving explanations, and sharing their previous knowledge, experiences and opinions about the animals and the conservation of marine biodiversity based on scientific reasoning. Therefore, this study provides evidence of the important role that AquaRio could play in providing opportunities for families to have conversations about biodiversity and conservation while raising awareness about the impacts of human activities on the oceans.
Acrocomia aculeata
is a native palm distributed widely throughout Brazil that is used in a diverse array of products from the food industry to biodiesel oil production. This study uses nine ...microsatellite loci to assess the genetic diversity, spatial genetic structure (SGS), and mating system of
A. aculeata
. A total of 200 samples were collected from four populations (Fusquinha—FU, Padre Josimo—PJ, Gleba XV-GB, and Amparo—AM), in São Paulo State, Brazil. We also collected fruits from 20 randomly selected seed trees in the FU population to assess mating patterns, for a total of 246 genotyped embryos. We identified a total of 103 alleles and all loci were polymorphic. The average observed heterozygosity (
H
o
) ranged from 0.410 (AM) to 0.531 (FU) and expected heterozygosity (
H
e
) ranged from 0.547 (PJ) to 0.615 (GB). The average fixation index (
F
) ranged from 0.043 to 0.254 for FU and AM populations, respectively. The coancestry coefficient (
θ
x
y
) was significant up to 38 m in PJ the population and 71 m in AM. Individual palm outcrossing rates were predominantly high (
t
m
= 0.985) and the paternity correlation (
r
p
(
m
)
= 0.02) was significantly low, indicating a high probability of the occurrence of half-sibs. Compared to other palm species, the studied populations show high levels of genetic diversity. Our results confirm that
A. aculeata
is primarily allogamous, with no significant paternity correlation, and seeds should be harvested from at least 40 trees to ensure high levels of genetic diversity in seed collection programs.

ABSTRACT: In this study, we used audiovisual recordings to analyze the conversations of 10 family groups during a visit to the temporary exhibition “Oceanos” (Museu da Vida, Rio de Janeiro, Brazil) to understand how visitors engage with themes of marine biodiversity conservation. The results provide evidence that the exhibition aroused the interest of families by using objects of different nature to portray topics of interest linked to the family context. Families talked to each other and interacted with the exhibition by sharing information about the oceans and marine biodiversity. Adults adopted facilitating behaviors: asking questions, reading panels and making associations with previous experiences that engaged children. Children actively participated by sharing their knowledge and opinions about the animals. The exhibition sensitized visitors in respect to the pollution of marine ecosystems by offering opportunities for conversation and reflection on behaviors that impact marine biodiversity and ways to protect it.
Pressure on tropical forests by agriculture and livestock expansion, frequently leads to highly fragmented and isolated populations. Limited gene fow drives increased drift and genetic ...differentiation among populations, ultimately reducing the overall genetic diversity of forest tree species. Balforoudendron riedelianum (Engl.) Engl., commonly known as pau marfm (ivory tree), a valuable Brazilian hardwood tree used in carpentry and building, is currently endangered due to logging and forest fragmentation. Information on genetic diversity and structure of remnants populations is necessary to support its conservation and sustainable management. Microsatellite markers are an effective tool for understanding and quantifying the effects of fragmentation on genetic diversity. Seven microsatellite markers were developed and validated using a sample of 98 individuals. The number of alleles per locus ranged from 3 to 25, the observed and expected heterozygosities from 0.051 to 0.909 and 0.050 to 0.930, respectively, the fxation index corrected for null alleles from 0.036 to 1.0 and all markers were found in linkage equilibrium. This microsatellite marker set is suitable to estimate population genetic parameters in support of sustainable management and conservation, and to assess relatedness and parentage in breeding populations.
