ChemSusChem, Volume 18, Issue 6, March 15, 2025.Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Mating Patterns and Postzygotic Barriers in a Hybrid Swarm of Two Closely Related Pigeon Species
Ecology and EvolutionHybrid zones provide a valuable framework for understanding evolutionary pathways. We investigated mating patterns and reproductive barriers using captive individuals derived from a natural hybrid swarm between hill pigeons (Columba rupestris) and feral ...

Endangered species and endangered knowledge
Zootaxa, 2009 The recent discovery of a new species of land iguana in the Galapagos (Tzika et al. 2008; Gentile et al. 2009; Gentile & Snell 2009) is indeed an exciting novelty, of great interest to all zoologists and evolutionary biologists. This species being apparently represented only by a very small population with a very limited range, it was described as ...

Disentangling functional spaces: a multidimensional framework for ecology and conservation
Ecography, EarlyView.Trait‐based ecology often relies on a single functional space, where diverse traits are combined into one multivariate framework. While convenient, this approach risks masking ecological strategies because variance is often dominated by a few traits, such as body size.

U.S. Conservation Policy Reconsidered [PDF]
Research related to the Endangered Species Act tends to take the presence of that policy as given and focus on issues of implementation and effects. This paper seeks to reconsider U.S. conservation policy entirely.

Ecography, EarlyView.Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

, 2014 La supervivència de l’ésser humà i, per extensió, de les espècies animals, sempre ha estat estretament lligada amb la seva capacitat d’adaptació. Actualment, el patrimoni religiós de la majoria de ciutats d’Europa, per una disminució de l’assistència, es pot considerar en perill d’extinció.
