Where will the dhole survive in 2030? Predicted strongholds in mainland Southeast Asia

open access: yesConservation Science and Practice, 2022
Dhole (Cuon alpinus) is threatened with extinction across its range due to habitat loss and prey depletion. Despite this, no previous study has investigated the distribution and threat of the species at a regional scale.

Modes of Growth in Dynamic Systems [PDF]

open access: yes, 2012
Regardless of a system's complexity or scale, its growth can be considered to be a spontaneous thermodynamic response to a local convergence of down-gradient material flows.

Influence of prey depletion and human disturbance on tiger occupancy in Nepal

open access: yesJournal of Zoology, 2013
AbstractTigers are globally endangered and continue to decline due to poaching, prey depletion and habitat loss. In Nepal, tiger populations are fragmented and found mainly in four protected areas (PAs). To establish the use of standard methods, to assess the importance of prey availability and human disturbance on tiger presence and to assess tiger ...

Environmental effects on magnetic fluorescent powder development of fingermarks on bird of prey feathers [PDF]

open access: yes, 2019
A comparison study of the effects of environmental conditions on the development of latent fingermarks on raptor feathers using green magnetic fluorescent powder was undertaken using both sebaceous loaded and natural fingermark deposits.

Night shift: expansion of temporal niche use following reductions in predator density. [PDF]

open access: yesPLoS ONE, 2012
Predation shapes many fundamental aspects of ecology. Uncertainty remains, however, about whether predators can influence patterns of temporal niche construction at ecologically relevant timescales. Partitioning of time is an important mechanism by which

Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

open access: yes, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Trophic upgrading and mobilization of wax esters in microzooplankton [PDF]

open access: yes, 2019
Heterotrophic protists play pivotal roles in aquatic ecosystems by transferring matter and energy, including lipids, from primary producers to higher trophic predators.

Native Prey and Invasive Predator Patterns of Foraging Activity: The Case of the Yellow-Legged Hornet Predation at European Honeybee Hives. [PDF]

open access: yesPLoS ONE, 2013
Contrary to native predators, which have co-evolved with their prey, alien predators often benefit from native prey naïveté. Vespa velutina, a honeybee predator originating from Eastern China, was introduced into France just before 2004.

The centrosomal deubiquitylase USP21 regulates Gli1 transcriptional activity and stability [PDF]

open access: yes, 2016
USP21 is a centrosome-associated deubiquitylase (DUB) that has been implicated in the formation of primary cilia - crucial organelles for the regulation of the Hedgehog (Hh) signaling pathway in vertebrates. Here, we identify KCTD6 - a cullin-3 E3-ligase

Foraging conditions for breeding penguins improve with distance from colony and progression of the breeding season at the South Orkney Islands

open access: yesMovement Ecology, 2021
Background According to central place foraging theory, animals will only increase the distance of their foraging trips if more distant prey patches offer better foraging opportunities.
