“…Throughout their extensive evolutionary narratives, the three populations have taken up residence within divergent ecological domains, thereby hinting at the plausible presence of localized adaptation. While the precise degree of distributional overlap and genetic interchange amongst these populations remains shrouded in obscurity, the likelihood of their existence cannot be discounted [21,22]. Neglecting to account for such local adaptations when employing SDMs in conservation or management decisions may result in erroneous characterizations of species' responses to environmental changes throughout their ranges, thus misdirecting conservation efforts [23].…”

Local adaptation has been increasingly involved in the designation of species conservation strategies to response to climate change. Marine mammals, as apex predators, are climatechange sensitive, and their spatial distribution and conservation requirements are critically significant for designing protection strategies. In this study, we focused on an ice-breeding marine mammal, the spotted seal (Phoca largha), which exhibits distinct morphological and genetic variations across its range. Our objectives were to quantify the ecological niches of three spotted seal populations, construct the species-level model and population-level models that represent different regions in the Bering population (BDPS), Okhotsk population (ODPS) and southern population (SDPS), and conduct a conservation gap analysis. Our findings unequivocally demonstrated a clear niche divergence among the three populations. We predicted habitat contraction for the BDPS and ODPS driven by climate change; in particular, the spotted seals inhabiting Liaodong Bay may face breeding habitat loss. However, most spotted seal habitats are not represented in existing marine protected areas. Drawing upon these outcomes, we propose appropriate conservation policies to effectively protect the habitat of the different geographical populations of spotted seals. Our research addresses the importance of incorporating local adaptation into species distribution modeling to inform conservation and management strategies.

Nutritious diet is one of the most important factors in the successful management of captive animals. Basic methods for selecting diets for marine mammals have been described in the literature, yet methods developed for certain marine mammal species kept under specific conditions are quite rare. The diets of three male and two female spotted seals, Phoca largha Pallas, 1811, kept in sea pens at the Primorsky Aquarium, Branch of the NSCMB FEB RAS (Vladivostok, Russia), are discussed in the article. The diets have been formulated based on the natural biological processes of this species in the wild. Information on them has been obtained from our own observations and from literature sources. Based on individual needs, adjustments have been made to the diets of the spotted seals, including pregnant and lactating females. The main food items of the spotted seal were Pacific herring, Clupea pallasii, Atka mackerel, Pleurogrammus monopterygius, commander squid, Berryteuthis magister, pink salmon, Oncorhynchus gorbuscha, chum salmon, Oncorhynchus keta, char, Salvelinus sp., capelin, Mallotus villosus, and shrimp, Pandalus sp. It has been found that the physiological condition of the animals (molting, reproductive status, sex, and age) directly influences the qualitative and quantitative parameters of food intake. The diet and body weight of the spotted seals were significantly influenced by seasonal changes (water and air temperature and natural biological rhythms). The obtained data can be used for selection of optimal feeding of P. largha.
