First report of Peckia (Squamatodes) ingens (Walker, 1849) (Diptera: Sarcophagidae) colonizing human corpse in the Neotropical region
We report a case of male corpse colonization found inside a residence in the municipality of Areia, ParaĂba, Brazil. The body was found in the gaseous stage of decomposition and was colonized by fly larvae. We reared the larvae collected at the crime scene on a temperature-controlled. We supplied beef as a feeding substrate for the larvae until adult emergence to allow taxonomic identification. Three specimens of Peckia (Squamatodes) ingens emerged in the laboratory. Thus, we present the first record of the flesh-fly Peckia (S.)Â ingens colonizing a human corpse in Neotropical region, updating the list of species with forensic potential. In addition, information on the total time of the species development and the implications of these findings for the consolidation of forensic entomology in the Northeast region were discussed
First Record of Scirtidae (Coleoptera) Associated With Decaying Carcasses in the Neotropical Region
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Sazonalidade e Padrões Diários de Atividade de Machos de Euglossina (Hymenoptera: Apidae: Apini) e PreferĂŞncias por Fragrâncias Artificiais em um Remanescente de Brejo de Altitude na ParaĂba
Euglossina bees are distributed exclusively in the Neotropical Region, with around 200 species described. By the usage of artificial
fragrances as baits, it is possible to accomplish faunistic inventories and study several ecological aspects of the group. To contribute to the knowledge
of the biodiversity of a Montane Atlantic Forest remnant, concerning to Euglossina, seven fragrances were used as baits in different climatic periods. A
total of 2,981 males belonging to 14 species of Euglossina were collected. Abundance and richness were higher in the dry period. Changes in the daily
activity patterns were observed from a period to the other. Generally, in the rainy season the males were more active after 11am and in the dry season
between 8am and 11am. Euglossa carolina (Nemésio), Eulaema nigrita (Lepeletier) and Eulaema cingulata (Fabricius) were the most abundant
species on both periods. Ionone beta was the fragrance which attracted more species and specimens.As abelhas Euglossina ocorrem exclusivamente na região neotropical, com cerca de 200 espécies descritas. Utilizando-se fragrâncias
artificiais como iscas, Ă© possĂvel realizar levantamentos faunĂsticos e estudar diversos aspectos ecolĂłgicos do grupo. Com o intuito de contribuir
ao conhecimento da biodiversidade dos brejos de altitude, no tocante às abelhas Euglossina, sete fragrâncias artificiais foram utilizadas como iscas
em um remanescente na cidade de Areia, ParaĂba, em distintos perĂodos climáticos. Foram coletados 2.981 machos pertencentes a 14 espĂ©cies de
Euglossina. A abundância e a riqueza foram maiores no perĂodo de estiagem, havendo variação no horário de atividade de um perĂodo para o outro.
De modo geral, no perĂodo chuvoso os machos foram mais ativos apĂłs as 11h e, no de estiagem, entre 8h e 11h. Euglossa carolina (NemĂ©sio), Eulaema
nigrita (Lepeletier) e Eulaema cingulata (Fabricius) foram as espĂ©cies mais abundantes nos dois perĂodos. Beta ionona foi a fragrância que atraiu
o maior nĂşmero de espĂ©cies e indivĂduos
Megasoma gyas rumbucheri Fischer, 1968 (Coleoptera: Scarabaeidae: Dynastinae): first record from a Conservation Unit in Brazil
A single male of Megasoma gyas rumbucheri Fischer, 1968, an endangered subspecies, was collected during a study of insect fauna in a protected area of Caatinga, State of Paraíba, Brazil, being the first record of the subspecies collected in a Conservation Unit and the most recent record of the subspecies in latitudes above the River São Francisco
Ecological Roles of Coleoptera Associated with Carcasses in Caatinga
The ecological roles of Coleoptera fauna associated with pig carcasses exposed in a Caatinga area were examined. Tray, pitfall and modified
Shannon traps were settled together to collect these insects during two seasons (dry and rainy). 4,851 beetles were collected, belonging to 19 families
and 88 species. The most abundant ecological category was predator/parasite (72.7%), followed by omnivorous (15.1%), necrophagous (10.9%)
and incidental (1.3%). Future researches on the biology of predator/parasite species are required to understand their possible forensic utility for
postmortem interval estimate.O papel ecológico da coleopterofauna associada a carcaças de porcos em uma área de Caatinga foi examinado. Para captura desses insetos
foram utilizadas armadilhas do tipo bandeja, pitfall e Shannon modificada, durante duas estações (seca e chuvosa). 4.851 coleópteros foram coletados,
pertencentes a 19 famĂlias e 88 espĂ©cies. A categoria ecolĂłgica mais abundante foi predador/parasita (72,7%), seguida por onĂvoro (15,1%), necrĂłfago
(10,9%) e incidental (1,3%). Futuros estudos sobre biologia das espĂ©cies predadoras/parasitas sĂŁo necessários para se determinar sua possĂvel utilidade

First Record of Scirtidae (Coleoptera) Associated with Decaying Carcasses in the Neotropical Region
During a two-year study on the insect fauna associated with pig carcasses in an Atlantic forest remnant in JoĂŁo Pessoa, state of ParaĂba,
Brazil, 127 adult Scirtes sp. were collected. This is the first record of specimens of the family Scirtidae associated with carcasses in the Neotropical
