Catalyst‐Free Mass Polymerization and Characterization of Bio‐Polyhydroxhyurethanes Based on Resorcinol Bis(Cyclocarbonate)

open access: yesMacromolecular Materials and Engineering, EarlyView.
Non‐isocyanate polyhydroxyurethanes (PHUs) were synthesized from resorcinol bis(cyclocarbonate) and eco‐friendly diamines under mild, catalyst‐free conditions. The resulting polymers were extensively characterized for their structural, thermal, and mechanical properties, as well as processability and adhesion performance.

Can restoring wolves aid in lynx recovery?

open access: yesWildlife Society Bulletin, 2011
Herein, we examine the hypothesis that relatively low densities of snowshoe hares (Lepus americanus) and the imperiled status of lynx (Lynx canadensis) may be partially due to an ecological cascade caused by the extirpation of gray wolves (Canis lupus ...

Present status and distribution of the Lynx in the Swiss Alps

open access: yesHystrix, the Italian Journal of Mammalogy, 2001
<strong>Abstract</strong> To evaluate the population trend of lynx in the Swiss Alps, we analysed the spatial and numerical development of signs of presence found from 1995 to 1999 and compared them with previous years.

Characteristics of spatial use and importance of landscape features for recovering populations of Eurasian lynx (Lynx lynx)

open access: yesActa Biologica Slovenica, 2020
Following the extirpation from Central and Southeastern Europe by the end of the 19th  century, Eurasian lynx (Lynx lynx) was reintroduced in the Alps and Dinarics.

Favourable areas for expansion and reintroduction of Iberian lynx accounting for distribution trends and genetic diversity of the European rabbit [PDF]

open access: yes, 2016
Although on a local scale Iberian lynx distribution is determined by the availability of prey rabbits, recent modelling analyses have uncovered broad-scale disagreements between these two species’ distribution trends.

SMBH Seeds: Model Discrimination with High Energy Emission Based on Scaling Relation Evolution

open access: yes, 2017
We explore the expected X-ray (0.5-2keV) signatures from super massive black holes (SMBHs) at high redshifts ($z\sim5-12$) assuming various models for their seeding mechanism and evolution.

open access: yes, 2014
The bird collection of the Instituto de Investigação Cientítica Tropical (Lisbon, Portugal) holds 5598 preserved specimens (skins), mainly from Angola, Mozambique, Guinea-Bissau, São Tomé and Principe, and Cape Verde.

Frugivory‐mediated trophic cascades: how apex predators can shape the recruitment of a fleshy‐fruited tree

open access: yesOikos, EarlyView.
The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.

Recovery of the Alpine lynx Lynx lynx metapopulation [PDF]

open access: yes, 2017
We use the case of the Eurasian lynx Lynx lynx in the Alps to discuss how to implement existing directives and recommendations, as well as how to integrate biological concepts, into practical conservation and wildlife management.

Oral Papillomatosis in Canada Lynx (Lynx canadensis) [PDF]

open access: yesJournal of Wildlife Diseases, 2007
We observed 11 cases of oral papillomatosis among 48 free-ranging Canada lynx (Lynx canadensis) that had been shipped to Colorado for translocation purposes. Lesions were 1-3 mm, multifocal, nonpigmented sessile masses and occurred on the ventral lingual surface. Adverse clinical signs were not observed.
