Long-term assessment of birds' extirpation from a tropical agroecosystem

چکیده
To better understand the processes that may lead to potentially avoidable extinction events, it is important identify influence of change in communities at local scale. We compiled bird lists from a field station with an artificial wetland system and history drastic changes land use Colombian Andes. This data expands 1974 2018. Our assessment uses three criteria recognize extinction: looking short-term (last 5 years) variation, comparison between baseline most recent data, time between. These also allowed us quantify substantial colonization recolonization events. found 5.9% previously recorded species had become extirpated, 5.2% can be considered probably 6.7% are possibly extirpated. Moreover, there was turnover foraging guilds which implies transition community's functional diversity. The loss wetlands addition afforestation plan mid-90s study site likely constitute leading factors for observed gains losses agroecosystem. highlight importance multicriteria community-level studies distinguish apparent persistence actual extirpation event over long term. Artificial agroecosystems should studied as they could complement regional conservation targets.

The need for long-term care (LTC) represents a “new social risk,” one that overlaps with and complements systems of care that pre-date such programs, complicating LTC program design. This commentary expands on Ikegami’s discussion of how these structural factors must be accommodated, as well as historical and cultural factors that influence public expectations of such a...

Long-term care (LTC) must be carefully delineated when expenditures are compared across countries because how LTC services are defined and delivered differ in each country. LTC’s objectives are to compensate for functional decline and mitigate the care burden of the family. Governments have tended to focus on the poor but Germany opted to make LTC universally available ...

Lowland extirpation of anuran populations on a tropical mountain
Background Climate change and infectious diseases threaten animal and plant species, even in natural and protected areas. To cope with these changes, species may acclimate, adapt, move or decline. Here, we test for shifts in anuran distributions in the Luquillo Mountains (LM), a tropical montane forest in Puerto Rico by comparing species distributions from historical (1931-1989)and current data...
