Habitat loss and simplification lower arthropod richness but not diversity

open access: yesEcosphere
Habitat loss is rarely truly random and often occurs selectively with respect to the plant species comprising the habitat. Such selective habitat removal that decreases plant species diversity, that is, habitat simplification or homogenization, may have ...

The long-term survival and climatic distribution of mixotrophic and mycoheterotrophic orchids

open access: yesActa Societatis Botanicorum Poloniae, 2023
Orchid germination depends on their fungal partner; however, there are no broadscale analyses evaluating the actual overlap between orchids and their mycorrhizal symbionts.

Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]

open access: yes, 2019
Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus

A nonnative habitat‐former mitigates native habitat loss for endemic reef fishes [PDF]

open access: yesEcological Applications, 2019
Animals that select the best available habitats are most likely to succeed in degraded environments, but ecological change can create evolutionarily unfamiliar habitats that may be under‐ or over‐utilized by native fauna. In temperate coastal waters, eutrophication and grazing have driven a global decline in native seaweeds and facilitated the ...

Historical Analysis Exposes Catastrophic Seagrass Loss for the United Kingdom

open access: yesFrontiers in Plant Science, 2021
The spatial extent of seagrass is poorly mapped, and knowledge of historical loss is limited. Here, we collated empirical and qualitative data using systematic review methods to provide unique analysis on seagrass occurrence and loss in the United ...

ORGANIC FARMS AS REFUGES FOR SMALL MAMMAL BIODIVERSITY [PDF]

open access: yes, 2009
Habitat fragmentation, the process by which relatively continuous habitats is broken into smaller pieces, occurs in natural systems but is to a high degree also human- induced through landscape use.

Breeding habitat loss linked to declines in Rufous Hummingbirds

open access: yesAvian Conservation and Ecology
Habitat loss is the primary driver of biodiversity decline worldwide, but it remains unknown how land-cover change and, in general, habitat loss impact many migratory species, such as the Rufous Hummingbird ( Selasphorus rufus ).

Some Relative Humidity Reactions of the Wood-Louse, Cylisticus Convexus (Isopoda: Porcellionidae) in an Olfactometer [PDF]

open access: yes, 2017
Generally, wood-lice are confined to habitats where the saturation deficit is low and damp surfaces are available. Cylisticus convexus (De Geer) is one of many species that are found in a relatively wet habitat (Edney, 1954).

Temporal Dynamics of the Goose Habitat in the Middle and Lower Reaches of the Yangtze River

open access: yesRemote Sensing, 2022
The middle and lower reaches of the Yangtze River are the most important areas for geese to overwinter in the East Asian–Australasian Flyway, where about 180,000 geese fly to overwinter each year.

Climate change and the selective signature of the Late Ordovician mass extinction [PDF]

open access: yes, 2012
Selectivity patterns provide insights into the causes of ancient extinction events. The Late Ordovician mass extinction was related to Gondwanan glaciation; however, it is still unclear whether elevated extinction rates were attributable to record ...
