Summary: Reef shark species have experienced significant declines due to human activities, and their conservation requires policies at local, federal, and global levels. This study monitored the blacktip reef shark population around Moorea and within the world's largest shark sanctuary for nine years. The results indicate that local and likely federal policies have been effective in maintaining stable juvenile shark density. However, some nursery areas showed increasing shark densities, potentially due to changes in reproductive behavior or habitat type and resources. Water temperature did not have a significant impact on juvenile shark density over time.

Summary: Shark species are overfished and conservation efforts require genetic data, which can be costly and time-consuming to collect. This study developed a set of microsatellite markers as an efficient and economical sampling method for addressing knowledge gaps in genetic stock identification, shark behavior, and reproduction.

Summary: This study reveals the presence of skin lesions caused by Huffmanela sp. eggs on great hammerhead sharks and blacktip reef sharks in the Arabian Gulf. The unique morphometrics of the eggs led to the discovery of a new species named Huffmanela selachii n. sp. This finding contributes to our understanding of the diversity and ubiquity of Huffmanela sp. in marine creatures, marking the first report of Huffmanela on these shark species in the Arabian Gulf.

Summary: Marine collagen has been gaining attention as a biomaterial substitute in tissue engineering due to its role in cellular signaling mechanisms, especially in mesenchymal stem cells (MSCs). This study investigated the integrin receptor binding mechanism and proliferation of MSCs when exposed to marine collagen derived from blacktip reef shark and blue shark compared to bovine collagen. The results showed that marine collagen enhanced MSC proliferation, adhesion, and shape maintenance by interacting with specific integrin subunits, triggering further signaling cascade mechanisms.

Summary: Understanding microevolutionary forces and population structure is crucial for effective management of exploited species. This study investigated the genetic structure of blacktip sharks using mitochondrial sequences and SNP-containing loci. The results revealed three genetically distinct units, suggesting regional philopatry and local adaptation. The findings highlight the importance of conserving essential habitats to maintain adaptive variation and enhance species resilience against environmental change.

Summary: This study monitored and sampled blacktip reef sharks in nursery habitats to improve understanding of shark reproductive behavior and biology. The research revealed evidence of plastic philopatric behavior, with some female sharks changing parturition areas between seasons while others consistently returning to the same site. Additionally, resource allocation within some shark litters appeared to be unbalanced. These findings contribute to our knowledge of shark populations and can inform future conservation strategies.

Summary: The coevolution between predators and prey has led to prey species using low-risk habitats for survival during early development. However, the physical and geographical characteristics of these habitats can also limit scientific research. This study identified and analyzed the characteristics of blacktip shark nurseries in the north-western Gulf of Mexico using gillnet monitoring.

Summary: Shark neonates often have wounds at the umbilicus, which can be used to estimate their age and growth. This study quantified the changes in umbilicus size of blacktip reef shark neonates, developing a classification system and validating its accuracy. Similar regression relationships can be used for other viviparous shark species.

Summary: Our research analyzed the stress response of the protected tropical shark species, the blacktip reef shark, under different temperature and fishing stress conditions, showing that 1α-OHB did not play a typical glucocorticoid role under these stressors. Furthermore, we demonstrated for the first time ontogenetic differences in plasma 1α-OHB levels in sharks of different developmental stages.

Summary: Brain size is positively related to gill surface area, with larger individuals typically having larger brains and gill surface areas. Gill surface area may pose an upper limit on the allometric slope of brain mass, suggesting that larger brains require larger gill surface areas to support them.

Summary: Non-lethal methods were used to evaluate the reproductive hormone profiles of blacktip sharks off the coast of southern Florida. The study found that testosterone concentrations in males peaked during months of peak spermatogenic activity, while females displayed higher estradiol concentrations during months of peak vitellogenic and ovulatory activity. However, due to the limited sample sizes and lack of reproductive status confirmation, further research is needed to fully understand the reproductive cycle of this species in the region.

Summary: Global climate change affects oceanic characteristics and animal distribution. Inconsistencies in the migratory movement of blacktip sharks off the U.S. East Coast challenge current knowledge. Published data can be interpreted in multiple ways and perpetuate uncertain observations, calling for further research on the movement ecology of blacktip sharks in this region.

Summary: By sequencing RADseq loci in the gray reef shark population in the Indo-Pacific, we found evidence of a range expansion originating near the Indo-Australian Archipelago. This species shows a continuous genetic structure and high dispersal ability, suggesting that management plans should be designed on a range-wide rather than a local scale.

Summary: This study examined 102 Holarctic bird species and found that most species experienced an increase in population size and geographical range since the Last Glacial Maximum, with wetland birds showing a later and greater increase in population size. However, there was no correlation between changes in population size and range size. This lack of correlation between Species Distribution Models (SDMs) and Bayesian Skyline Plots (BSPs) reconstructions suggests that changes in population densities may play a role independent of range shifts.

Summary: In this study, a multidisciplinary approach was used to investigate the genetic and phenotypic differentiation between two cryptic ant species with restricted dispersal. Results showed strong differentiation in genetic, morphological and chemical traits between species, and also within species among different localities. Behavioral experiments revealed reproductive isolation between species, and cuticular hydrocarbons, mtDNA sequences and number of hairs were shown to be reliable criteria for species discrimination.
