The discipline of ecology and evolutionary biology (EEB) has long grappled with issues of inclusivity and representation, particularly for individuals with systematically excluded and marginalized backgrounds or identities. For example, significant representation disparities still persist that disproportionately affect women and gender minorities; Black, Indigenous, and People of Color (BIPOC); individuals with disabilities; and people who are LGBTQIA+. Recent calls for action have urged the EEB community to directly address issues of representation, inclusion, justice, and equity.

Up to 10% of uveitis cases occur in children, with notable implications due to the risk of chronicity and vision loss. It can result from infections, autoimmune and autoinflammatory diseases, trauma, or masquerade syndromes. Primary care providers are vital in early detection, symptom management, and timely specialist referral.

Article Synopsis
  • - The survey, developed by the International Uveitis Study Group, aimed to assess how uveitis and retina specialists use current terminology and multimodal imaging (MMI) for diagnosing white dot syndromes (WDS).
  • - Out of 432 initial respondents, 263 completed the survey, revealing that most participants specialize in uveitis and utilize MMI, with nearly 90% using it for WDS diagnosis but showing varied usage of the term WDS.
  • - The findings suggest a strong consensus among specialists for redefining WDS based on anatomical location rather than the current clinical term, emphasizing MMI's role in enhancing diagnostic precision.

Article Synopsis
  • This study is the first of its kind to statistically assess how well the Collaborative Ocular Tuberculosis Study (COTS) calculator predicts the need for antitubercular therapy (ATT) in patients with suspected tubercular uveitis (TBU) in an international setting.
  • The main goal was to determine if a score of 4 or higher on the COTS calculator effectively guides the initiation of ATT.
  • Results showed that among 492 participants, 45.7% received a high probability for ATT initiation, and the COTS-5 score showed the highest specificity at 88.7%, suggesting its effectiveness compared to clinician judgment.

Instruments attached to animals ('biologgers') have facilitated extensive discoveries about the patterns, causes, and consequences of animal behavior. Here, we present examples of how biologging can deepen our fundamental understanding of ecosystems and our applied understanding of global change impacts by enabling tests of ecological theory. Applying the iterative process of science to biologging has enabled a diverse set of insights, including social and experiential learning in long-distance migrants, state-dependent risk aversion in foraging predators, and resource abundance driving movement across taxa.

Article Synopsis
  • The study investigates the elbow joint mechanics of Central bearded dragons, revealing that their elbow exhibits significant rotational movements during walking.
  • Using advanced imaging techniques (XROMM), the researchers found that the radius and ulna rotate independently, which helps maintain a necessary position for the hand (manus) during movement.
  • The findings suggest that this independent movement of the radius and ulna could be an ancestral trait in lizards and possibly in other non-avian reptiles.

Human disturbance is contributing to widespread, global changes in the distributions and densities of wild animals. These anthropogenic impacts on wildlife arise from multiple bottom-up and top-down pathways, including habitat loss, resource provisioning, climate change, pollution, infrastructure development, hunting and our direct presence. Animal behaviour is an important mechanism linking these disturbances to population outcomes, although these behavioural pathways are often complex and can remain obscured when different aspects of behaviour are studied in isolation from one another.

Ocular syphilis is a re-emerging inflammatory eye disease with a clear gender imbalance, disproportionately affecting men. We investigated the impact of gender on the presentation, management practices and clinical outcomes of this condition. Data generated from a study of patients consecutively diagnosed with ocular syphilis who attended a subspecialist uveitis service at one of four hospitals in Brazil over a 30-month period were disaggregated for analysis by gender.

Intercellular adhesion molecule 1 (ICAM-1) is a central cell adhesion molecule for retinal transendothelial migration of the leukocytes in non-infectious posterior uveitis. Inhibiting gene transcription reduces induction of ICAM-1 in inflamed retinal endothelium. Based on published literature implicating transcription factor ETS-1 as an activator of gene transcription, we investigated the effect of ETS-1 blockade on ICAM-1 levels in cytokine-stimulated human retinal endothelial cells.

Climate change reduces snowpack, advances snowmelt phenology, drives summer warming, alters growing season precipitation regimes, and consequently modifies vegetation phenology in mountain systems. Elevational migrants track spatial variation in seasonal plant growth by moving between ranges at different elevations during spring, so climate-driven vegetation change may disrupt historic benefits of migration. Elevational migrants can furthermore cope with short-term environmental variability by undertaking brief vertical movements to refugia when sudden adverse conditions arise.

There is an increasing body of knowledge regarding how COVID-19 may be associated with ocular disease of varying severity and duration. This article discusses the literature on the ocular manifestations associated with COVID-19, including appraisal of the current evidence, suggested mechanisms of action, associated comorbidities and risk factors, timing from initial infection to diagnosis and clinical red flags. The current literature primarily comprises case reports and case series which inevitably lack control groups and evidence to support causality.

The complex metabolic relationship between the retinal pigment epithelium (RPE) and photoreceptors is essential for maintaining retinal health. Recent evidence indicates the RPE acts as an adjacent lactate sink, suppressing glycolysis in the epithelium in order to maximize glycolysis in the photoreceptors. Dysregulated metabolism within the RPE has been implicated in the pathogenesis of age-related macular degeneration (AMD), a leading cause of vision loss.

Characterised by intraocular inflammation, non-infectious uveitis includes a large group of autoimmune and autoinflammatory diseases that either involve the eye alone or have both ocular and systemic manifestations. When non-infectious uveitis involves the posterior segment of the eye, specifically the retina, there is substantial risk of vision loss, often linked to breakdown of the inner blood-retinal barrier. This barrier is formed by non-fenestrated retinal vascular endothelial cells, reinforced by supporting cells that include pericytes, Müller cells and astrocytes.

Article Synopsis
  • - Sarcoidosis is a multi-system disease that can cause uveitis and affects both adults and children, with different clinical presentations based on age.
  • - "Early-onset sarcoidosis" occurs in children under 5 due to a genetic mutation, while "adult-type sarcoidosis" starts between ages 8 and 15, often linked to environmental factors.
  • - Treatment for pediatric sarcoidosis is limited and usually mirrors other non-infectious uveitis, commonly using medications like methotrexate and adalimumab, with the need for long-term follow-up as the condition can continue into adulthood.
