Hormone laboratories located “on-site” where field studies are being conducted have a number of advantages. On-site laboratories allow hormone analyses to proceed in near-real-time, minimize logistics of sample permits/ ...

These new species are discovered and described based on the combination of their distinctive COI barcodes, Barcode Index Numbers (BIN), overall morphology, genitalia, and life histories. The genus Nystalea Guenée ...

Introduction: Molecular divergence thresholds have been proposed to distinguish recently separated evolutive units, often displaying more accurate putative species assignments in taxonomic research compared to traditional ...

A new species of trematode of anaporrhutine gorgoderid, from the gill chambers of the Munda round ray Urotrygon munda in Costa Rica is described, based on an integrative taxonomic approach that includes the use of light ...

The paper focuses on the failure to account for the value of standing tropical forests, and of ecosystem services in general, in economic decision-making. This blindness to the values of nature has led to overexploitation, ...

Climate warming threatens sea turtles, among other effects, because high temperatures increase embryo mortality. However, not all species and populations are expected to respond the same way because they could have different ...

Buttressed trees provide mechanical support for themselves and offer essential ecological functions, such as nutrient acquisition, while being one of the largest sources of volume or biomass estimation variation in ...

Virtually all plants employ direct and indirect defenses against herbivores. While it is known that plant defenses can be affected by below- ground symbiotic microbes under controlled condi- tions, studies showing these ...
