- Adult Sex-Ratio Bias Does Not Lead to Detectable Adaptive Offspring Sex Allocation Via Nest-Site Choice in a Turtle With Temperature-Dependent Sex Determination.
Crowther C, Adams CIM, Fondren A et al. · Ecology and evolution · 2024-11 · open access
Sex-ratio theory predicts that parents can optimise their fitness by producing offspring of the rare sex, yet there is a dearth of empirical evidence for adaptive sex allocation in response to the adult sex ratio (ASR). This is concerning, as anthropogenic disruption of the sex ratios of…

- Green Turtle Feeding on Terrestrial Leaves Reveals Energy Pathway From Land to Sea.
Robinson NJ, Killackey RP, Valverde-Cantillo V et al. · Ecology and evolution · 2024-11 · open access
We report on an adult male green turtle ( Chelonia mydas ) feeding on fallen leaves from a terrestrial tree, frangipani ( Plumeria rubra ), in the waters in front of Cabuyal-a known sea turtle nesting beach-on the north Pacific coast of Costa Rica. This observation, in conjunction with similar…

- Prey Cue Preferences Among Northern Cottonmouths ( Agkistrodon piscivorus ) Acclimated to Different Year-Long Diets: Genetics or Experienced-Based Plasticity?
Lutterschmidt WI, Perelman ZE, Roth ED et al. · Integrative organismal biology (Oxford, England) · 2024-11 · open access
Chemoreception and recognition of specific prey are important sensory modalities for optimizing foraging success in snakes. Field observations suggest that cottonmouths are generalists, despite the specific epithet of the species ( piscivorus ) suggesting a fish prey preference. Because…
- Trends in Urban Wild Meat Trade of Chelonians (Turtles and Tortoises) in the Peruvian Amazon.
Mayor P, Bodmer R, Moya K et al. · Animals : an open access journal from MDPI · 2024-11 · open access
Culturally, chelonians are important sources of nutrition and income for rural and urban people in tropical rainforests, but urban trade can cause declines in wild populations. This study analyses the urban chelonian trade and its trends to better understand the impact on free-living populations in…

- Infanticide is driven by unfamiliarity with offspring location and associated with androgenic shifts in mimic poison frogs.
Lewis AR, Goolsby BC, Juarez BH et al. · Hormones and behavior · 2024-11 · open access
Infanticide is widespread across the animal kingdom, but the physiological drivers of infanticide versus care or neglect are relatively unexplored. Here, we identified salient environmental and physiological antecedents of infanticide in the mimic poison frog (Ranitomeya imitator), a biparental…

- Central pattern generator control of a vertebrate ultradian sleep rhythm.
Fenk LA, Riquelme JL, Laurent G · Nature · 2024-11 · open access
The mechanisms underlying the mammalian ultradian sleep rhythm-the alternation of rapid-eye-movement (REM) and slow-wave (SW) states-are not well understood but probably depend, at least in part, on circuits in the brainstem 1-6 . Here, we use perturbation experiments to probe this ultradian rhythm…
- Multifocal cutaneous neoplastic vascular proliferations in a rainbow boa (Epicrates cenchria) collection with boid inclusion body disease.
Broering Ferreira A, Fonteque JH, Withoeft JA et al. · PloS one · 2024-11 · open access
Reports on neoplastic processes in snakes are sparse regardless of their location, origin or behavior. Here, we describe the occurrence of multifocal cutaneous neoplastic processes consistent with hemangioma and hemangioendothelioma, with a differential diagnosis of angiomatosis, in a colony of…

- Ionizing radiation has negligible effects on the age, telomere length and corticosterone levels of Chornobyl tree frogs.
Burraco P, Gabor C, Bryant A et al. · Biology letters · 2024-11 · open access
Introduction Ionizing radiation can directly damage DNA or interact with other molecules in the cell, causing indirect damage to DNA and even compromising organ function or individual survival. Radiation can also lead to the upregulation of repair or buffering pathways such as repair mechanisms or…

Gita Dewi Rosifa, Melfa Aisyah Hutasuhut, Zahratul Idami · Jurnal Ilmiah Biologi UMA (JIBIOMA) · 2024-11 · open access
Anura are amphibians capable of living in both terrestrial and aquatic habitats, yet they are highly sensitive to environmental changes. Some Anura species can adapt well, while others are more vulnerable to such changes. The Lau Timah River, located in Desa Bukum, Sibolangit, North Sumatra, is…
- Seasonality influences skin bacterial community structure and anti-Bd function in two anuran species.
Zhang H, Ma H, Deng J et al. · Frontiers in microbiology · 2024-11 · open access
Introduction Bacterial communities on the skin are an important first line of defense against pathogens in amphibians. Experimentally removing skin bacteria increases morbidity associated with chytridiomycosis, whereas the addition of certain nascent bacteria reduces morbidity and mortality in some…

Tian X, Lin X, Xie Q et al. · Biology · 2024-11 · open access
1. Introduction China is a major aquaculture country. During the breeding process, incidents such as arbitrary feeding and non-standard breeding often occur, resulting in a serious excess of nitrogen, phosphorus, and other elements in the breeding water, ultimately leading to high pollution of…
