Residency and site fidelity are important parameters in population ecology for many species as they indicate the temporal and spatial use for individuals. Although both terms are clearly different, they are used interchangeably due to lack of clarity in their definitions and the ways to assess them, especially in bottlenose dolphins (Tursiops spp.). Individuals with well-defined patterns of residency and site fidelity may be more vulnerable to anthropogenic disturbances; thus, the study of these parameters may help to better assess such impacts. However, interspecific differences and logistical restrictions for the study of dolphins have prevented consensus. We set out to investigate the factors that have influenced measurements of residency and site fidelity in bottlenose and a set of other dolphin species through a retrospective (~30 y: 1990 to 2019) literature review. We found 117 scientific papers with a two-fold increasing trend approximately every 15 years, with 50% published in only four journals. Most of the studies were developed in the United States, followed by Australia and Europe, likely due to strict policies for marine mammal conservation. Author collaboration network analysis showed highly atomized national groups in which North American organizations formed the biggest cluster, followed by Australia, Africa, and Europe. However, large worldwide gaps still exist, possibly because of the heterogeneity in marine mammal sampling efforts and limited information availability in the North Pacific, Central and South America, Africa, Asia, and the Indian Ocean. We found 30 different classification methods in which 12 were based on defined categories. We provide conceptual aid to distinguish between the use of both terms, as well as guidance to tackle the challenge of defining patterns of temporal use due to the variability of thresholds for classifying individuals. A paradigm shift is needed to create comprehensive, standardized, and generalized assessments of residency and site fidelity, which can be compared based on their performance across different populations of bottlenose dolphins around the world.

Background: Oral diseases remain among the most common non-communicable diseases worldwide, affecting almost half of the world’s population. This is partly because there has been a separation of the mouth from the rest of the body and human health, and psychological aspects such as personality, thoughts, and emotions are not taken into account in the dental office. The objective was to analyze the relationship between oral health conditions and personality traits in adult patients who underwent dental treatment at the Center for Health Studies and Services. Methods: This was a descriptive, observational, and correlational study, carried out at the Center for Health Studies and Services. A total of 184 patients who attended the dentistry area in the period from October 2022 to May 2023 participated in the study, of which 59.78% were women and 40.21% men. The age of the population was 18 to 79 years, with the age range of 21–40 years being the most prevalent (48.37%). Results: The results show that although the hygiene of the population treated was good (0.77 ± 0.79) and that the perception of oral health was positive (14.34 ± 9.43), the means and percentages of oral pathologies and parafunctional habits were high (i.e., DMFT: 9.98 ± 5.40; attrition: 87.50%; onychophagia: 45.10%). It is noteworthy that both the correlation, network, multiple line regression, and logistic regression analyses showed associations of the personality, gender, and age variables with a history of caries and oral hygiene as well as with parafunctional habits. Conclusions: Therefore, variations in both the personality and the age and gender of the patients treated have repercussions on oral health conditions, which can be used in the prevention of oral diseases and in health promotion.

The habitat and its environmental conditions, when optimal, influence the reproduction and survival of organisms, since they can have an impact on demographic parameters such as adult sex ratio (ASR), density, and functional traits (morphological, physiological). Few studies evaluate these factors as a whole in contrasting habitats (such as mangroves and pastures), especially in crab species such as Cardisoma guanhumi . We hypothesized that mangroves would be a favorable habitat for C. guanhumi at a local and regional scale because the environmental conditions (lower temperature, soft and clayey substrate) would have a positive effect on its population dynamics and morphological traits. In order to test this hypothesis, we selected 12 sites on the coasts of the Gulf of Mexico. We found an effect of habitat on ASR, which was male‐biased in the mangrove and female‐biased in the pasture at a local (by site) and regional scale. Furthermore, crab density was higher in the mangrove and decreased in both habitats as soil hardness increased. In addition, females were heavier and larger (quela, carapace, ventral plate) in the mangrove, and these traits were positively related to burrow temperature in this habitat. Our results support the hypothesis that mangroves are the optimal environment for the development of C. guanhumi . However, although this threatened species has been able to adapt to modified habitats such as pastures, its vulnerability is increased by the surrounding environmental conditions, predation, and commercial exploitation, and the viability of its populations may be affected if it persists in these modified environments.

Background/Objectives: Although the benefits of breastfeeding on the development and health of the infant are well known, the relationship between breastfeeding, oral health and attachment style or emotional bonding is not fully known. This research sought to explore, from a comprehensive perspective, the associations between breastfeeding history and children’s attachment styles, as well as the relationships between breastfeeding history and oral health indicators within conceptual psychophysiological frameworks discussed in the literature. Methods: This was a cross-sectional (descriptive and analytical) and correlational study. In this work, the associations of breastfeeding with attachment and oral health were analyzed in 100 children between 9 and 11 years old at a primary school in the municipality of José Azueta, Veracruz, Mexico, from December 2023 to September 2024 by a clinical history, dental examinations (Oral Hygiene Index-Simulated (OHI-S), Dental Caries History (DEOPT) and Detection of Malocclusions (DAI)) and the Attachment and Interaction Styles Instrument. Results: Significant differences were found in the security and closeness attachment style, the oral-hygiene index, the caries index, and occlusion by type of breastfeeding, showing better values in boys and girls who were exclusively breastfed. Likewise, both in the correlation analysis and in the multiple regression model, associations were observed between having been exclusively breastfed and the attachment style and oral indices. Conclusions: Our data show the importance of breastfeeding in pubertal children, since it was associated with better attachment and oral health; however, these findings reflect patterns of co-occurrence and should not be interpreted as causal relationships.
