ORCHIDEE‐MAN: Incorporating Mangrove Processes in the Global Vegetation Model of ORCHIDEE

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract The mangrove ecosystem is characterized by high carbon sequestration rates and plays a crucial role for the exchange of carbon between land and ocean. Understanding the carbon dynamics of mangroves under climate change and human disturbances is therefore essential for quantifying their contributions to global carbon cycle.

Does Karyotype Structure Co‐Occurrence Patterns in a Chromosomally Diverse and Species‐Rich Clade of Lizards (Genus Sceloporus)?

open access: yesJournal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim We investigated the biogeographic consequences of chromosomal speciation, or structural changes in chromosome arrangement that lead to reproductive isolation, an intriguing speciation mechanism with implications for the phylogenetic and geographic distribution of species and chromosomal diversity. Location. North and Central America. Taxa.

Notes on the Reproductive Biology of the Alabama Red Hills Salamander (Phaeognathus hubrichti ) [PDF]

open access: yes, 2003
Living Amphibia exhibit two major life history modes, possession of an aquatic larval stage or direct development, with the latter assumed to be the derived evolutionary condition (Duellman and Trueb 1986, Wake 1989).

Pathological Parthenogenesis in Viviparous Toothcarps [PDF]

open access: yesNature, 1958
IN viviparous toothcarps parthenogenesis has been described in Lebistes reticulatus 1,2 and Xiphophorus helleri 2, while in this species also some cases of development of ovarial teratomas, caused by pathological parthenogenesis, are known3. In addition to these cases we observed a new one, namely in Heterandria formosa.

Embryological development and comparative analysis of Anguis colchica (Nordmann, 1840): Insights into ossification and morphological traits in anguimorph lizards

open access: yesJournal of Anatomy, Volume 247, Issue 6, Page 1157-1173, December 2025.
This study examines the embryonic development of Anguis colchica across three stages, highlighting key morphological and skeletal features. Ossification begins before stage 6, with cranial bones forming early, while frontal and parietal bones remain unfused at stage 7.

Next-generation sequencing yields a nearly complete mitochondrial genome of the Forsyth’s toad-headed agama, Phrynocephalus forsythii (Reptilia, Squamata, Agamidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Forsyth’s toad-headed agama, Phrynocephalus forsythii, is endemic to the Taklamakan Desert. A nearly complete mitochondrial genome of one individual for this species was determined by next-generation sequencing.

Colony Specificity in the Xenogeneic Combinations among Four Botrylloides Species (Urochordata, Ascidiacea) [PDF]

open access: yes, 2002
Xenogeneic rejection reactions were histologically examined among four compound ascidians of the genus Botrylloides; B. simodensis, B. lentus, B. fuscus and B. violaceus, to compare with the allogeneic rejections of these species.

Disentangling the interrelations of body mass, egg deposition site, climate and microhabitat use in frogs and salamanders

open access: yesEcography, Volume 2025, Issue 11, November 2025.
Amphibians exhibit a large diversity in reproductive and developmental strategies, which in turn are linked to their body size, life history and habitat. Here, we explore why terrestrial egg laying frogs are on average smaller than aquatic egg laying ones and whether this pattern also exists in salamanders.

A review and illustrated description of Musca Crassirostris, one of the most neglected livestock hematophageous flies [PDF]

open access: yes, 2019
Tabanids, stomoxyine flies, hippoboscids and tsetse flies are the most well‐known brachyceran biting flies of livestock. Only a few other higher Diptera have developed the unique mouthparts required for blood feeding.
