Long-term trends in the use of a protected area by small cetaceans in relation to changes in population status

open access: yesGlobal Ecology and Conservation, 2014
The requirement to monitor listed species in European designated sites is challenging for long-lived mobile species that only temporarily occupy protected areas.

Stability of Perovskite Indoor Photovoltaics: A Focused Review and a Call for Standardized Stability Reporting

open access: yesAdvanced Energy Materials, EarlyView.
While perovskite solar cells have been widely studied, including their stability, perovskite indoor photovoltaics (IPVs) have only recently emerged. Nevertheless, more studies are appearing in the literature. The systematic stability study of IPVs is crucial, particularly given the inconsistencies in reported methodologies and results, which call for ...

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

An approach to predicting linear trends in tagging-related mortality and tag loss during mark-recapture studies

open access: yesFrontiers in Ecology and Evolution
Using tags within a mark-recapture framework allows researchers to assess population size and connectivity. Such methods have been applied in coastal zone habitats to monitor salt marsh restoration success by comparing the movement patterns of Mummichogs

Promoting engagement in embryology through gamified student‐developed small group sessions

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Learning embryology is often challenging for students as it requires conceptualizing morphological changes to embryologic structures across time. To further complicate the process, while some structures transition to permanent structures, others disappear or degenerate.

Spring migration of Ruffs Philomachus pugnax in Fryslân: estimates of staging duration using resighting data [PDF]

open access: yes, 2010
Seasonal bird migration involves long flights, but most time is actually spent at intermediate staging areas. The duration of stay at these sites can be evaluated with mark–recapture methods that employ day-to-day local encounters of individually marked ...

The estimation of grizzly bear density through hair‐snagging techniques above the tree line

open access: yesWildlife Society Bulletin, 2015
Assessing grizzly bears' (Ursus arctos) abundance in the Arctic has been challenging because of the large scale of their movements and the remoteness of field locations.

The home range of the signal crayfish in a British lowland river [PDF]

open access: yes, 1997
The signal crayfish Pacifastacus leniusculus (Dana), a native of north-western North America, is now a common resident in some British fresh waters following its introduction to England in 1976 (Lowery & Holdich 1988).

Is Circular Also Sustainable? Assessing Circularity and Sustainability to Enhance Legitimacy in Agri‐Food Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The agri‐food industry faces major sustainability challenges, requiring a shift in companies' approach. Circular economy principles offer a promising path by enhancing resource efficiency, reducing waste, and valorizing by‐products. However, the integration of sustainability and circularity practices remains limited, especially in developing ...

Challenges and opportunities for monitoring wild Nile crocodiles with scute mark-recapture photography

open access: yesKoedoe: African Protected Area Conservation and Science, 2018
The global conservation status of Nile crocodiles (Crocodylus niloticus) was last assessed in 1996. The species presents particular difficulty in monitoring because it can be cryptic, require expertise to handle, and caudal tail tags and transmitters are
