Clinical ultrasonography in loggerhead sea turtles (Caretta caretta): imaging of pathological features

Veterinární Medicína, 2016
Ultrasound scans were used to image pathological features in sea turtles. Scans were carried out in 19 loggerhead sea turtles, weighing from 2 to 21 kg, during the course of clinical examinations using 3.5 and 7.5 MHz sector transducers.

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

Integrative Zoology, EarlyView.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Brokers, Collaborators and Knowledge Translators: Expanding the Role of Research Assistants in Geographic Research

Asia Pacific Viewpoint, EarlyView.
ABSTRACT While ‘local’ research assistants (RA) often play a key role in knowledge production in fieldwork‐based disciplines like geography, their role and agency often remain silenced. This paper brings together scholarship in feminist geography and critical development studies to reposition RAs as brokers, collaborators, and knowledge translators.

More Than a Course, More Than a Method: Study Circles as a Pedagogical and Research Method Working With Asylum Seekers Across Language Barriers and Differences

Area, EarlyView.
Short Abstract Acknowledging the limits of participatory action research, this paper explores how to include participants in the asylum process despite facing practical and ethical challenges. Concretely, the paper argues for research to align with participating organisations' knowledge, methods and resources.

Teaching a Geography of Hope

Area, EarlyView.
Short Abstract This paper reflects on the pedagogical possibilities of cultivating a ‘geography of hope’. ABSTRACT Amid intersecting global crises—war, genocide, the erosion of academic freedom and the deepening precaritisation of higher education—this paper reflects on the pedagogical possibilities of cultivating a ‘geography of hope’.

Researcher Positionality and Relational Power: Playing With ‘Researching Up’ and ‘Researching Down’ in Critical Reflexivity

Area, EarlyView.
Short Abstract This paper draws on the concepts of ‘researching up’ and ‘researching down’, often used to distinguish between relative ‘power over’ or ‘power under’ interlocutors. It suggests that by mobilising these concepts through feminist geography as a relational analytic rather than oppositional categories, we can generate new insights into our ...

Analysis of Sea Turtle Bycatch by Andalusia Pelagic Longline Fleet in the Northeast Atlantic

Fisheries Oceanography, EarlyView.
ABSTRACT The Northeast Atlantic is one of the most crucial foraging grounds for juvenile loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea), while also serving as an important fishing area for the Andalusia surface longline fishery. The main aim of present study is to assess the sea turtle interaction with the Andalusia pelagic

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

New Phytologist, EarlyView.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...
