Fluid escape structures as possible indicators of past gas hydrate dissociation during the deposition of the Barremian sediments in the Recôncavo Basin, NE, Brazil

open access: yesBrazilian Journal of Geology
: Empty elliptical vesicles are observed in outcrops of Barremian very fine clayey sandstone to siltstone lacustrine slurry deposits of the Pitanga Member (Maracangalha Formation), exposed in the Maré Island, Southern Recôncavo Basin, Brazil.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Elliptic islands and zero measure escaping orbit in a class of outer billiards

open access: yesDiscrete and Continuous Dynamical Systems
We study outer billiard systems around a class of circular sectors. For semi-discs, we prove the existence of elliptic islands occupying a positive proportion of the plane. Combined with known results, this shows the coexistence of stability and diffusion for this system.

Linking distribution and return‐on‐investment models to optimize woody management for prairie grouse in Nebraska

open access: yesThe Journal of Wildlife Management, EarlyView.
We modeled prairie grouse abundance across Nebraska and projected future woody encroachment to estimate population losses. By combining predicted gains from woody treatments with avoided losses and treatment costs, we mapped return on investment to identify areas for woody treatments that maximize benefits to greater prairie‐chickens and sharp‐tailed ...

PRDM1 Knockdown Promotes Ferroptosis and Sunitinib Sensitivity by Modulating the PI3K/Akt Signaling Through Inhibition of ESM1 Transcription in Renal Cell Carcinoma

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Renal cell carcinoma (RCC) is a commonly occurring and considerable burden on public health. Although chemotherapy benefits patients with advanced RCC, sunitinib resistance leads to a poor prognosis. Ferroptosis is also involved in sunitinib resistance in RCC.

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Category-Sensitive Escape from Islands in Limbum and Asante Twi

open access: yesLanguages
While strong islands generally constitute domains from which extraction is not possible, it has been observed that under certain conditions, they may allow DP but not PP gaps. Based on the recent literature on Asante Twi (Kwa, Ghana) and on novel data from Limbum (Grassfields Bantu, Cameroon), this paper shows that strong island configurations in these

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

open access: yesOikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

open access: yesPeople and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Relational values, motivations, and benefits drive community commitment to urban predator control for ecological restoration

open access: yesPeople and Nature, EarlyView.
Abstract Volunteers play a crucial role in urban ecological restoration, and in the Aotearoa New Zealand context, volunteer effort is a central tool used to drive landscape‐scale conservation outcomes. Here, we identify the motivations and benefits that drive community involvement and commitment to conservation initiatives, drawing on a unique case ...
