“…The fact that these mangrove‐barrier tactics were documented for two distinct Guiana dolphin population suggests the possibility of using the mangrove edges as static barriers to facilitate foraging by other populations of the species across its wide latitudinal distribution in the western Atlantic Ocean. In Babitonga Bay, southeastern Brazil, despite these events have not yet been observed, Guiana dolphins seem to prefer areas close to the mangroves, likely benefiting from the marine productivity of the area (Cremer, 2000). On the other hand, Guiana dolphins from the Norte Bay, southern Brazil, use less intensively the mangrove region, possibly because of its proximity to urban areas (Wedekin et al, 2010).…”

Guiana dolphins use mangrove margins as a natural barrier to chase fish prey

The behavioral plasticity among and within cetacean species can be driven by their prey sources, local adaptations to environmental features, and/or interactions with human activities. One of the tactics displayed by cetaceans is the barrier feeding, in which individuals or groups herd fish schools against natural and non‐natural barriers to restrict movements of their prey. Coastal odontocetes, for example, are known for using shorelines and underwater slopes to trap their prey. Here, we documented two distinct populations of Guiana dolphin using the mangrove margins as a natural barrier to herd and capture fish. The observations took place in the Cananéia estuary, São Paulo State, southeastern Brazil, and in the Paranaguá estuary, Paraná State, southern Brazil. A total of 63 dolphins over eight encounters were observed performing six different events using mangroves as a natural barrier, summing both study areas. These findings not only expand our understanding of the behavior plasticity of the species but also call attention to the importance of the mangrove ecosystem directly to Guiana dolphins and indirectly to the components of their food web.

“…Five sea turtles species occur in Brazil, out of seven that inhabit the world. They are green turtle (Chelonia mydas), hawksbill turtle (Eretmochelys imbricata), loggerhead turtle (Caretta caretta), olive turtle (Lepidochelys olivacea), and leather turtle (Dermochelys coriacea) (Cremer et al 2020). In Brazil, all sea turtle species are included in the Red Book of the Brazilian Fauna Threatened by Extinction (Brasil 2018).…”

Cytological grading of canine mast cell tumors: correlation with histologic grading and survival time

et al. 2023

Mast cell tumors are one of the most common neoplasia in dogs and cytopathology and/or histopathology examinations are used for diagnosis. Histologic grading is considered the gold standard test to predict the prognosis of this neoplasia. However, studies have been conducted using the cytological grading system to provide similar information in a faster, less invasive, and more accessible way. This study aimed to investigate cytological graduation and correlate it with histological grading and the survival time of dogs diagnosed with cutaneous mast cell tumors at the Veterinary Hospital of “Universidade Federal de Uberlândia” over five years. For that, cytological and histological slides from 72 animals were reviewed. The statistical methods used were the kappa test for agreement between grading systems, the Kaplan-Meier for survival time, Cox regression for comparison of cytological and histological grades and survival time. The cytological grading when compared to the two-tier histologic grading, high and low grades, had a moderate agreement (kappa 0.566). When the correlation between survival time and the cytological grade was evaluated, there was a higher death rate in the group with high-grade mast cell tumors compared to low grade, pointing to a correlation between survival time and cytological grade (p=0.009). In conclusion, the cytological grade is useful to treatment planning and providing prognostic information that precedes tumor removal, showing a good correlation with the two-tier histologic grading and with the survival time of the animals.
