Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

The chaetognatha of the Eastropic Expedition, with notes as to their possible value as indicators of hydrographic conditions [PDF]
ENGLISH: The purpose of this study was to investigate the possibility that certain species of Chaetognatha found in Eastern Tropical Pacific waters can serve as biological indicators of oceanographic features. "Indicator" organisms have been found useful

An integrated approach to balance freshwater connectivity restoration and invasion risk
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Report of the Inter-American Tropical Tuna Commission for the year 1955 [PDF]
ENGLISH: This is the fifth year of investigations, by the Inter-American Tropical Tuna Commission, of the fisheries for tunas and tuna-bait fishes in the Eastern Pacific Ocean adjacent to the shores of the Americas.

ABSTRACT Wildlife trafficking poses a critical threat to global biodiversity, contributes to organized crime, and has disproportionate impacts on underserved and Indigenous communities. Although international legal instruments, such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and institutional collaborations,

Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.
