The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

open access: yesJournal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

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

open access: yesJournal 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

Marine Flora and Fauna of the Northeastern United States Echinodermata: Crinoidea [PDF]

open access: yes, 1990
The crinoid fauna of the continental margin (0-1500 m) of northeastern North America (Georgia to Canada) includes 14 species in 13 genera and 5 families. We introduce the external morphology and natural history of crinoids and include a glossary of terms,

Histopathological investigation of wound healing activities of Lucilia sericata Larva and Achillea sintenisii extract combinations in diabetic rat wound model

open access: yesMedical and Veterinary Entomology, EarlyView.
Lucilia sericata larvae secrete bioactive compounds that promote wound debridement and antimicrobial defence in chronic tissue injuries. Achillea sintenisii extract offers phytotherapeutic support, enhancing healing through anti‐inflammatory and regenerative properties. Diabetic Wistar rats were treated topically with Furacin®, larval secretions, plant

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

open access: yesEcological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Marfan Syndrome Associated With Intellectual Disability and Behavioral Anomalies: Further Evidence for the Effect of Compound Heterozygous Variants in FBN1 on Phenotypic Severity

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 1021-1035, May 2026.
ABSTRACT Marfan syndrome (MFS) is a rare connective tissue disorder characterized by involvement of the cardiovascular, ocular, and musculoskeletal systems. Pathogenic variants in FBN1 cause most of the MFS cases; however, intellectual disability (ID) is rarely observed. A non‐consanguineous Pakistani family with four affected individuals was recruited.

Population Genetics Reveals Insights Into Cryophytum Biogeography in South Africa

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study investigated the population genetic structure, biogeography and environmental drivers of divergence in Cryophytum crystallinum and C. guerichianum, two closely related Mesembryanthemoideae species, and evaluated a putative hybrid. Cryophytum crystallinum showed genetically similar populations at either end of its coastal range, with ...
