From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

open access: yesOikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Strongly minimal Jonsson sets and their properties

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2015
This article introduced and considered the Johnson sets and their fragments. And respectively was considered strongly minimal Jonsson sets. On this basis, introduced the concept of the independence of special subsets of existentially closed submodel of the semantic model.

Decision trees, monotone functions, and semimatroids [PDF]

open access: yes, 2013
We define decision trees for monotone functions on a simplicial complex. We define homology decidability of monotone functions, and show that various monotone functions related to semimatroids are homology decidable.

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them

open access: yesPeople and Nature, EarlyView.
Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

Improving forest age estimation to understand subtropical forest regrowth dynamics using deep learning image segmentation of time‐series historical aerial photographs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Accurately estimating forest age is key to understanding how forests recover and evaluating restoration success. We developed a two‐step deep learning approach using historical greyscale aerial photographs to map forest age at fine spatial scales. By combining a pre‐trained model with localized fine‐tuning, our U‐Net + ResNet50 architecture achieved ...

Convex fragmens of strongly minimal Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2015
This article introduced and discussed the concepts of minimal Jonsson sets and respectively strongly minimal Jonsson sets. On this basis, we introduce the concept of independence of special subsets of existentially closed submodel of semantic model. The concept of independence leads to the concept of basis and then we have the Jonsson analogue of the ...

Tourism Labor Market and the Attainment of the 2030 Agenda for Sustainable Development Goals: Pending Challenges, Ongoing Opportunities and More Responsible and Inclusive Scientific Research for the Advancement of the Tourism Industry

open access: yesSustainable Development, EarlyView.
ABSTRACT Concerning human resources, research in the tourism sector has traditionally focused on a personnel‐managerial perspective rather than a labor market‐condition analysis per se, limiting the examination of its unique working ecosystem and distinct socioeconomic particularities. This has evidenced an apparent thematic research gap in the tourism

The similarity of closures of Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
This article is devoted to the study model - theoretic properties of special closures of Jonsson sets. That is considered a syntactic similarity of Jonsson theories for universal existential sentences which true in these models. Due to the fact that the fragments of Jonsson sets are Jonsson theories, such an approach for the study of such theories is ...

Does Adopting Sustainable Development Goals Drive Corporate Change? The Case of the Goal on Gender Equality

open access: yesSustainable Development, EarlyView.
ABSTRACT This study investigates whether firms' adoption of Sustainable Development Goal (SDG) 5 on gender equality leads to measurable improvements in gender diversity within corporate leadership. Using a sample of large European firms from 2016 to 2023, we apply a difference‐in‐differences methodology to compare gender diversity outcomes between ...

Battlefield Triage

open access: yesVoices in Bioethics
Photo ID 222412412 © US Navy Medicine | Dreamstime.com ABSTRACT In a non-military setting, the answer is clear: it would be unethical to treat someone based on non-medical considerations such as nationality. We argue that Battlefield Triage is a moral
