Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Distribution and migrations of cetaceans in the Russian Arctic according to observations from aerial ice reconnaissance

NAMMCO Scientific Publications, 2002
This paper is based on 748 observations of belugas (Delphinapterus leucas) and 382 observations of baleen whales in the Russian Arctic, the majority of the data provided by aerial reconnaissance of sea ice (ARSI).

The Electrocardiogram of a Beluga Whale [PDF]

Circulation, 1953
In the course of our study of the comparative anatomy and physiology of the mammalian heart, it became necessary to develop a technic to obtain the electrocardiogram of the largest mammal of all. Because of its availability, the small white Beluga whale in northern waters was the first object of this research, prior to obtaining the record of a large ...

Stranded beluga (Delphinapterus leucas) calf response and care: reports of two cases with different outcomes

Polar Research, 2021
Given the remote, rugged areas belugas typically inhabit and the low rehabilitation success rate with any cetacean, it is rare to have the opportunity to rescue a live-stranded beluga.

Inductive Beluga: Programming Proofs [PDF]

, 2015
beluga is a proof environment which provides a sophisticated infrastructure for implementing formal systems based on the logical framework LF together with a first-order reasoning language for implementing inductive proofs about them following the Curry-Howard isomorphism.

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Of Whales and Genes: Unraveling the Physiological Response to Stressors in Belugas (Delphinapterus leucas) at the Molecular Level

Journal of Zoological and Botanical Gardens, 2021
Marine mammals, now more than ever, are exposed to environmental and anthropogenic stressors. A better understanding of stress physiology in marine mammals is warranted in order to assist in conservation efforts.

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.

Low prevalence of zoonotic food-borne parasites Toxoplasma gondii and Trichinella spp., but high prevalence of a potential marine Sarcocystis spp., in Eastern Beaufort Sea beluga whales (Delphinapterus leucas) harvested in the Canadian Arctic

Arctic Science
Beluga whales (Delphinapterus leucas (Pallas, 1776)) are traditional food sources for Inuit communities in the Canadian Arctic. In response to community concerns about zoonotic parasites (Toxoplasma gondii and Trichinella spp.), the aim of this study was
