New bryophyte taxon records for tropical countries 1 [PDF]
, 1997 This is the first in a series of papers listing new records, which will be published whenever sufficient new records have been found. The taxa are arranged by countries for an easier evaluation, e.g. updates of checklists. The initials of the contributor

Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Threatened bryophytes of the neotropical rain forest : a status report [PDF]
, 1992 Tropical deforestation, inevitably, leads to the local loss of bryophyte species. Recent studies show that the degree of species loss may vary considerably and depends on the scale or amount of habitat change that has occurred.

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT
Developmental Dynamics, EarlyView.Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Islands contribute disproportionately high amounts of evolutionary diversity in passerine birds [PDF]
, 2015 Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization
Ecography, EarlyView.Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Fissidens in the Neotropics [PDF]
, 1990 The land areas of the Western Hemisphere south of the United States support over 276 species of Fissidens (Wijk et al. 1962, 1969). This number is approximately 30% of the total number of species known.

Reconciling timber extraction with biodiversity conservation in tropical forests using reduced-impact logging [PDF]
, 2015 Over 20% of the world's tropical forests have been selectively logged, and large expanses are allocated for future timber extraction. Reduced-impact logging (RIL) is being promoted as best practice forestry that increases sustainability and lowers CO2 ...
