More Science Than Art: The First Botanical Garden in Portugal (c. 1650)
ABSTRACT Gabriel Grisley, a German physician, came to Portugal and founded a garden near the Xabregas River in Lisbon, during the 1610s under the Spanish kings' rule. In view of the utility a botanic garden represented for the kingdom, he was able to obtain a royal privilege from King João IV during the Restauration War against the Spanish (1640–1668).

Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

A new genus, Similihypoxys gen. nov., to Edessinae (Hemiptera: Heteroptera: Pentatomidae)
ABSTRACT A new genus for Edessinae close to Hypoxys is described. Similihypoxys gen. nov. Cunha & Fernandes is proposed for five new species, and one transferred from the genus Hypoxys: Similihypoxys infulatus (Breddin, 1904) comb. nov. (type species), S. connatus sp. nov., S. guianensis sp. nov., S. ineffigiatus sp. nov., S. quasinfulatus sp. nov. and

Among these are two species assigned to the genus Hyalyris Boisduval, 1870: Hyalyris fiammetta (Hewitson, 1852) and Hyalyris leptalina (C. Felder & R. Felder, 1865).

Controlling the Field: Memory, Labor, and Ethics in Oral Histories of Brazilian Human Genetics**
This article examines how oral histories of twentieth‐century human genetics in Brazil reveal the politics of memory of fieldwork. Through a comparative analysis of interviews with prominent geneticist Francisco M. Salzano and technician Girley V. Simões, who worked with him for most of his career, this study explores the narrative strategies each ...
