Brachyuran Crabs

The brachyuran fauna of the large southern Philippine island of Mindanao is poorly known, with only a few freshwater and estuarine crab species described or recorded in the last 30 years. Renewed interest in crab biodiversity has led to recent, small-scale surveys (2016–2019) of freshwater and estuarine habitats in various localities in Mindanao, which have yielded a good diversity of brachyuran crabs. As a result, a total of 26 species of brachyuran crab, representing 6 families (Hymenosomatidae, Oziidae, Gecarcinidae, Sesarmidae, Varunidae, and Ocypodidae), are reported here. Of these, 15 species are new records for the main island of Mindanao, 6 of which are also new records for the Philippines. Remarks on the taxonomy, distribution, and natural history of these species are also provided.

The natural history of Acentroptera basilica Guérin-Méneville, 1844 and A. cf. tessellata Baly, 1958 (Cassidinae: Sceloenoplini) associated with Aechmea aquilega Salisb. and Vriesea sp. (Bromeliaceae), respectively, is registered. Adults of both species are leaf scrapers, although larvae are leaf-miners. The immature stages of both species of Acentroptera are described and illustrated for the first time. The male and the female genitalia of A. basilica and new records for both species are also included.

AbstractThe recent collecting of five specimens of Atheris ceratophorus WERNER, 1895, together with an examination of material already deposited in various museums documents new records outside the Usambara Mountains to which the species had been believed to be endemic. Lepidosis and hemipenial characters have been investigated and tabulated to give an impression of the intraspecific variation. The data of the new specimens provide some information on the natural history of this species. The validity of A. nitschei rungweensis is discussed and a probable new record is given.

Abstract Context Characterization of the clinical features and natural history of non-functioning pituitary microadenomas (NFPmA) is limited by heterogenous and small-scale studies. Objective To characterize the clinical presentation and natural history of NFPmA and evaluate if imaging follow-up interval can be extended. Methods Retrospective single-center cohort study (years 2006-2021) of conservatively managed patients with NFPmA. Initial symptoms, pituitary function, and tumor size were assessed. A change in NFPmA size ≥ 2mm, as determined by pituitary or brain magnetic resonance imaging (MRI), was considered significant. Results There were 347 patients in the study cohort. Headache (78.4%) and fatigue (70.0%) were commonly reported despite no evidence of mass effect or significant pituitary hypofunction. Pituitary deficiencies at baseline were rare, with hypogonadism being most common (5.1%). During a median imaging follow-up period of 29 months (range 3-154), 8.1% of NFPmA grew. Growth incidence was 2.1 per 100 person-years with a mean and median time to growth of 38.1(SD± 36.4) and 24.5 (IQR12.0-70.8) months, respectively. Tumor growth was mild and not associated with new pituitary deficiencies or visual deficits. Conclusions These data indicate that the natural history of NFPmA is overall benign. Consequently, we propose that the initial MRI follow-up timeline for NFPmA can be extended up to 3 years unless a lesion is close to the optic chiasm, there are worrisome mass effect symptoms, or new pituitary deficiencies.

The species composition of batoid fishes from coastal waters of the Socotra Archipelago is reviewed, with confirmed records of the wedgefish Rhynchobatus djiddensis (Forsskål, 1775) and four new records of sharkrays, wedgefishes, and guitarfishes based on collected specimens, including one species from Abd al-Kuri Island, Rhina ancylostoma Bloch & Schneider, 1801 (Rhinidae), and three species from the main island Socotra, Acroteriobatus salalah (Randall & Compagno, 1995) and Rhinobatos punctifer Compagno & Randall, 1987 (Rhinobatidae), and Rhynchobatus australiae Whitley, 1939 (Rhinidae). Among the new records for the Socotra Archipelago, R. australiae represents the first verified record for the Arabian region. In addition, records of four stingray species (Dasyatidae) are verified based on underwater observations accompanied with photographs. All recorded batoid fishes are commercial species caught in the local small-scale fishery. Information on the identification and distribution of each species is provided.

AbstractThe recent collection of more than 50 specimens and more than 140 eggs of Tornier's cat-snake, Crotaphopeltis tornieri, together with an examination of material already deposited in various museums provides new records outside the previously known geographical range. Variation in external and internal characters has been examined and the results have been analyzed. In regard to several characters, including the internal ones, the population of the East Usambara Mountains in Tanzania is significantly different from the population of the West Usambara Mountains, probably indicating an early vicariance event between the two areas. Due to the lack of data relating to internal characters, the affinities of the populations further south remain obscure, and no nomenclatural conclusions have so far been reached. The recently acquired specimens provide new information on the natural history of the species.

Introduction: Available data on pituitary incidentalomas mostly derive from small-scale studies, with heterogeneous inclusion criteria and limited follow-up. No paper has focused specifically on clinically nonfunctioning pituitary in­cidentalomas (CNFPIs). Objective: To describe the charac­teristics and the natural history of patients diagnosed with CNFPIs. Methods: Retrospective multicenter cohort study evaluating hormonal, imaging, and visual field characteristics at diagnosis and during follow-up of CNFPIs investigated in 2 Pituitary Centers. Results: Three hundred and seventy-one patients were included (50.9% microadenomas, 35.6% males). Men were older and more likely to have a macroadenoma (p < 0.01). Totally, 23.7% of patients presented secondary hormonal deficits (SHDs), related to tumor size (higher in macroadenomas; p < 0.001) and age (higher in older patients; p < 0.001). Hypogonadism was the most frequent SHD (15.6%). Two hundred and ninety-six patients had follow-up data, 29.1% required surgery after first evaluation, and 97 had at least 3 years of follow-up. In total, 15.3% adenomas grew (more macroadenomas), but only in microadenomas patients with longer follow-up showed a higher growth trend. Totally, 5.2% of patients developed new SHDs (micro- vs. macroadenomas p = 1.000), and in 60% of them this was not associated with an increase in tumor size. Thirteen additional patients required surgery during follow-up (1 microadenoma at diagnosis). Conclusions: Macroadenomas and age are risk factors for SHD in CNFPIs, which occur at diagnosis in a quarter of patients. During follow-up, macroadenomas tend to grow more often, but microadenomas display higher growth trend as follow-up increases. Deterioration of pituitary function is not always related to adenoma growth.
