New approaches for capturing and estimating variation in complex #animal color patterns from digital photographs: application to the Eastern Box Turtle (Terrapene carolina) Color pattern plays a crucial role in various aspects of an organismโ€™s biology, including camouflage, mating, and communication. Despite its significance, methods to quantify and study color pattern variation are often lacking, especially for complex patterns that defy simple categorization. In this study, we developed algorithms to capture and obtain data on 19 different pattern measurements from digital images of 55 individuals of the Eastern box turtle Terrapene carolina sampled in the field and in a museum. The Eastern box turtle is an ideal species to study variation of complex color patterns as this species is easily encountered in the field and in museum collections in Northeastern US, has a relatively easy to identify bright color pattern against a dark background, and has a rigid shell structure, which removes problems related to body distortion. The selected measurements capture the different aspects of the complexity of the color pattern, including the symmetry of the pattern on the turtlesโ€™ scutes, a critical component in developmental and evolutionary studies. We estimated the variation of each of these 19 measurements across our samples. We determined how much of this variation was influenced by the sensitivity of the pattern capture algorithm due to non-standardized elements of the image acquisition, lighting conditions, and animal shape on pattern variation. To our knowledge, this is the first study to use a comprehensive set of pattern measurements to capture variation in a complex color pattern while also assessing the susceptibility of each of these measurements to noise introduced during data collection. Additionally, we carried out a citizen science approach to characterize the complexity of the color pattern based on human perception and determine which of the 19 pattern measurements best describe this complexity. The most variable measurements across individuals were blue and yellow contrast between the pattern and non-pattern coloration and the average size of objects. From our estimates of the measurement noise due to image acquisition and analysis, we found that the contrast differences reflected true pattern variations between individual turtles, whereas differences in the average size of objects were influenced by both individual turtle variation and measurement inconsistencies. We found that due to the complexity of the patterns, measurements had lower variability if they did not depend on the algorithm defining a set of discrete objects. For example, total area had much less measurement variability than average object area. Our study provides a comprehensive workflow and tools to study variation in complex color patterns in organisms sampled under non-standardized conditions while also estimating the influence of noise due to biological and non-biological factors.

A Jack of All Tradesโ€”Tawaki/Fiordland penguins are able to utilise diverse marine habitats during winter migration Migration and non-breeding movements are common across animal groups and are often driven by seasonal changes in habitat conditions. This behaviour is prevalent in crested penguins (Eudyptes sp.), which have evolved in and still primarily inhabit the subantarctic regions of the Southern Hemisphere. These species migrate outside the reproductive phase due to the limited year-round productivity around the breeding sites. Tawaki/Fiordland penguins (Eudyptes pachyrhynchus) are unusual in that they breed in temperate, continental New Zealand, an environment that appears productive enough to support year-round residency, yet they undertake extensive migrations during the non-breeding period. To investigate the drivers and patterns behind this behaviour, we used satellite telemetry to track 14 adult tawaki from across their breeding range during the winter of 2019. We examined whether migration routes differed by breeding location, and used maximum entropy (Maxent) modelling to identify environmental predictors of habitat use during the non-breeding period. All penguins followed a similar south-westerly trajectory toward the subantarctic waters south of Tasmania, irrespective of origin. Birds reached maximum distances of up to 2,193 km from their colonies, traveling a median total distance of 6,086 km over 135 days. Maxent models showed that mixed layer depth (i.e., the mixing height at the ocean surface) around 80 m was the strongest predictor of habitat suitability, aligning with known foraging depths in this species. Tawaki were associated with oceanic habitats ranging from polar to subtropical regionsโ€”a broader environmental range than other crested penguins, which tend to remain within a single water mass. These findings highlight the flexibility of tawaki in their use of marine habitats. This behavioural plasticity may suggest resilience to environmental variability, offering insights into why tawaki appear to be maintaining stable population trends while other New Zealand crested penguins are in decline.

Harnessing YouTube in advancing biodiversity conservation efforts and awareness across Africa YouTube (YT), an online video content application, has revolutionized the dissemination of information in various fields, including medicine, entertainment, and conservation science. Its potential in disseminating biodiversity conservation information has not been well assessed, especially in Africa, a biodiversity hotspot. When such assessments are conducted, they are usually species-specific, activity-based, or localized, making broader generalizations difficult. We evaluated the viewership and interaction of the videos posted about Africa across different organism groups, countries (geopolitical units), geographical regions, ecoregions, and channels (content creators). We assessed 431 videos, which collectively garnered 32,630,126 views, 364,700 likes, and 48,839 comments across 274 channels, five regions, and 31 African countries. The mean daily views varied significantly across countries, regions organism groups, and channels. Notably, more views per day were from biodiversity-rich countries, such as Madagascar, and most videos were posted from South Africa. Government and academic institutions posted fewer videos than individually owned and international biodiversity-related non-governmental organization (NGO) channels. Also, most channels posting about African biodiversity are based in the United States of America. Increased attention to biodiversity through social media engagement will likely stimulate external funding, international collaborations, policymaking, and participatory programs, benefiting both the public and organizations such as NGOs and governments. We observed a great need for increased participation by African-based content creators, primarily by government institutions, to effectively adopt a strong social media strategy to communicate information about biodiversity conservation, especially to the growing online population.
