Valuing changes in forest biodiversity [PDF]

open access: yesEcological Economics, 2009
The paper attempts to improve current understanding of the economic value of biodiversity. Instead of the prevailing approach of using only one indicator of biodiversity (typically, species richness) we provide evidence that it is possible to value changes in a number of attributes which describe complex characteristics of biodiversity, based on ...

A suite of essential biodiversity variables for detecting critical biodiversity change [PDF]

open access: yesBiological Reviews, 2017
ABSTRACTKey global indicators of biodiversity decline, such as the IUCN Red List Index and the Living Planet Index, have relatively long assessment intervals. This means they, due to their inherent structure, function as late‐warning indicators that are retrospective, rather than prospective.

Intrasexual cuticular hydrocarbon dimorphism in a wasp sheds light on hydrocarbon biosynthesis genes in Hymenoptera

open access: yesCommunications Biology, 2023
Transcriptomic and molecular analyses on Hymenoptera facilitated identification of cuticular hydrocarbon (CHC) pathway genes, whose phylogenetic distribution implies that the origin of CHC biosynthesis predates the arthropods’ colonization of land.

A landmark‐free analysis of the pelvic girdle in Sulawesi ricefishes (Adrianichthyidae): How 2D and 3D geometric morphometrics can complement each other in the analysis of a complex structure

open access: yesEcology and Evolution, 2023
Geometric morphometrics (GM) enable the quantification of morphological variation on various scales. Recent technical advances allow analyzing complex three‐dimensional shapes also in cases where landmark‐based approaches are not appropriate.

Humusica: Soil biodiversity and global change [PDF]

open access: yesBulletin of Geography. Physical Geography Series, 2018
Abstract Born in Trento (Italy, 2003) for the purpose of standardising vocabulary and units of humus form classification, after publishing a first synthetic classification e-book (Zanella et al. 2011) they do not cover all site conditions in the European area.

Synchronised monitoring of plant and insect diversity: a case study using automated Malaise traps and DNA-based methods [PDF]

open access: yesBiodiversity Data Journal
The occurrence and distribution of insects and their possible associations with plant species are largely unknown in Germany and baseline data to monitor future trends are urgently needed.

The geometric mean of relative abundance indices : a biodiversity measure with a difference [PDF]

open access: yes, 2011
This work is partly supported by the European Research CouncilThe 2010 Biodiversity Target of the Convention on Biological Diversity (CBD), set in 2002, which stated that there should be ‘a significant reduction of the current rate of biodiversity loss ...

Protosiphonorhinus patrickmuelleri gen. et sp. nov., the first fossil member of the sucking millipede family Siphonorhinidae (Colobognatha, Siphonophorida) described from Cretaceous Myanmar amber [PDF]

open access: yesEvolutionary Systematics
Millipedes (Diplopoda) are an abundant group of fossilized terrestrial arthropods throughout the Palaeozoic Era. However, there is a gap in the Mesozoic Period with only slightly more than a dozen fossils known, until more recent fossil records – mainly ...
