Within‐Ecosystem Comparison of Bigmouth Buffalo Ictiobus cyprinellus and Common Carp Cyprinus carpio Reveals Diverging Population Trajectories, Declining Recruitment, and a Lifespan of 148 Years

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Within‐ecosystem comparison of invasive common carp and native bigmouth buffalo reveals recruitment gaps for bigmouth buffalo longer than any other animal and lifespans approaching 150 years. In the post‐dam era, invasive common carp are increasing in number while native bigmouth buffalo are declining. ABSTRACT The bigmouth buffalo Ictiobus cyprinellus

Using spatial capture–recapture methods to estimate long‐term spatiotemporal variation of a wide‐ranging marine species

Ecography, Volume 2025, Issue 10, October 2025.
Determining population status to inform mitigation of anthropogenic threats requires statistical approaches that investigate spatial and temporal variation. In the face of climate change it is increasingly important to differentiate between changes in population size and redistributions of populations.

Leveraging Synteny to Generate Reference Genomes for Conservation: Assembling the Genomes of Hector's and Māui Dolphins

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT Escalating concern regarding the impacts of reduced genetic diversity on the conservation of endangered species has spurred efforts to obtain chromosome‐level genomes through consortia such as the Vertebrate Genomes Project. However, assembling reference genomes for many threatened species remains challenging due to difficulties obtaining ...

μCeta: A Set of Cetacean‐Specific Primers for Environmental DNA Metabarcoding With Minimal Amplification of Non‐Target Vertebrates

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Cetacean eDNA metabarcoding results from the aquarium pool samples using new cetacean‐specific primers. μCeta shows superior performance to detect and differentiate different cetacean species. ABSTRACT Biodiversity monitoring is crucial for understanding ecosystem dynamics and species distributions, particularly in the context of anthropogenic impacts ...

Skeletal and Cardiac Rhabdomyolysis in a Live-Stranded Neonatal Bryde's Whale With Fetal Distress

Frontiers in Veterinary Science, 2019
The main objective of wildlife forensic investigation is to recognize pathologic changes and cause of death. Even though it may not always be possible to determine the specific illness and/or etiology, the description and subsequent interpretation of the

Középső-miocén sziláscet (Cetacea: Mysticeti) humerusok a Pécs, danitzpusztai homokbányából

Földtani Közlöny, 2018
Az utóbbi húsz év gyűjtéseinek köszönhetően nagy mennyiségű sziláscet felkarcsont került elő egyetlen lelőhelyről, a Pécs melletti danitzpusztai homokbányából. A vizsgált humerusok a középső-miocénből (szarmata, badeni?) áthalmozottan, a pannóniai homokban találhatók. A területről összesen 19 db — kettő kivételével — közgyűjteményben elhelyezett ...

Retrieving Palaeoecological Information from Historic Fossil Finds: A Taphonomic Cold Case from Orciano Pisano (Central Italy) Reveals a Distinctive Trophic Interaction in the Pliocene Mediterranean Sea

Journal of Marine Science and Engineering
Evidence of trophic interactions between sharks and cetaceans is rather widespread in the fossil record, consisting as it does of tooth marks on bones and rarer teeth or tooth fragments embedded in (or associated with) skeletal remains.
