    Guys, does anyone know the answer?

    get you are an ecologist doing research at la selva biological research station in costa rica. which of the following likely has the least known about it? from EN Bilgi.

    La Selva Research Station

    La Selva Research Station

    The History

    OTS established the La Selva Research Station in 1968. Before it was under OTS leadership, La Selva was a farm dedicated to sustainable forest research owned by Dr. Leslie Holdridge.

    La Selva’s influence on tropical ecology is immeasurable and of great cultural significance, having served as a key training and research site for numerous professional scientists. La Selva Research Station pioneered private forest conservation in Costa Rica, as it was the first of what is now a large network of private forest reserves in the country.

    The species richness of La Selva is outstanding, with more than 2,077 species of plants; 125 species of mammals (72 of them bats); 470 species of birds; 48 amphibian species; 87 species of reptiles; 45 species of freshwater fish; and tens of thousands of insects, arachnids, and other arthropods.

    Ecological Uniqueness

    La Selva Research Station offers 1,600 hectares of well-preserved old-growth and recovering wet lowland tropical forest that abuts the Braulio Carrillo National Park. The 4 to 6 km wide forested corridor that connects La Selva at 35 m above sea level to the Barva Volcano at 2,906 m is one of the best-preserved elevational gradients in the tropics.

    La Selva sits within a complex biological, socioeconomic, and political landscape that has been significantly transformed over the last 40 years by a continuously expanding agricultural frontier, burgeoning human population, and accompanying major infrastructure. Protected areas, such as La Selva, provide a rich opportunity for studying how natural ecosystems respond to a broader landscape matrix of human uses.


    La Selva has some of the longest running ecological data sets in the tropics, spanning up to 40+ years. Long-term research of terrestrial and aquatic ecosystems has generated data on nutrient cycling, plant and animal demography (e.g. birds, trees, frogs, etc.), community interactions, and their responses to a changing climate.

    Key Research Themes

    Forest dynamics and nutrient cycling

    Forest succession

    Global change and human-nature interactions

    Agroecology Aquatic ecosystems


    La Selva’s juxtaposition of protected ecosystems and well-developed facilities is unique in the world’s wet tropics.

    Friendly and helpful staff, including a science team, is available to answer questions.

    La Selva can fully accommodate 180 overnight visitors.

    We offer a dining hall, laundry service, store, wireless internet, library, all-access trail, and on-station security.

    Our extensive network of paved and dirt trails (61 km) provides convenient access to a wide range of terrestrial and aquatic habitats.

    The station has several buildings that house laboratories and offices. There are two air-conditioned laboratories with basic equipment and several specialty areas including analytical, microbiology, and ambient labs.

    The herbarium houses more than 10,000 specimens of dried, pressed plants including fruits and seeds, as well as wet specimens, and several other reference collections.

    The Academic Center includes a conference room, four classrooms, four laboratories, and temporary offices for course faculty.

    Visitor Information

    La Selva is approximately a 2-hour drive from San José.

    Directions: Take the “Zurqui” Route 32 Highway through the Braulio Carrillo National Park towards Guapiles. After approximately 45 minutes, you will drive over the Sucio River; continue for 7 Km to a major intersection at a restaurant called Rancho Robertos. Turn left, and continue towards the town of Puerto Viejo in Sarapiquí. Follow the highway (Route 4) approximately 30 km to the entrance of La Selva (on your left). The entrance is 3 km before the intersection of Puerto Viejo.

    Buses leave from the “Caribeños” terminal in San José throughout the day. Make sure to take the bus to Puerto Viejo in Sarapiquí and not the bus to Puerto Viejo in (Talamanca) Limón!

    What is ecology?

    scientific study of interactions among and between organisms and their environment (biotic & abiotic)

    lowland tropical rain forests

    <1000 m altitude

    >100 mm/month of rain

    origin of ecology

    Ernst Haeckel (1866)

    'oikos' - house 'logos' - study

    approaches to ecology

    descriptive - what is the pattern?

    functional - why does the pattern exist?

    evolutionary - ultimate causal explanations

    methods to study ecology

    field - highly realistic but may lack control

    lab - highly controlled but lacks realism

    theoretical - mathematical models

    levels of ecological organization

    global, ecosystem (energy flux and cycling of nutrients, somewhat arbitrary), community (interactions among populations), population (poulation dynamics), species (organism)

    latitudinal gradient of biodiversty

    peaks at 0 degrees

    ascends and then descends from temperate to arctic zones

    tropical rain forest importance

    >60% of all described species

    half the world's vascular plants

    7% of Earth's land surface

    1.2% lost each year

    what defines the tropics?

    between 23.1 degrees N and S

    range of latitudes that receives direct sunlight at some point in the year

    warmest and wettest ecosystems

    very productive coriolis effect

    result of rotating earth

    cyclical patterns of wind are divided up into Hadley cells

    trade winds bring air back to beginning of the cycle

    realistic patterns do not perfectly reflect Hadley cells (disruptions between land and water)

    intertropical convergence zone (ICTZ)

    meeting point between tropical Hadley cells

    high precipitation

    precipitation patterns (global circulation)

    water rises as air rises

    then cools and condenses to form precipitation

    air coming down on the other ends sucks up the water, forming deserts

    horse latitudes

    a belt of calm air and sea occurring in both the northern and southern hemispheres between the trade winds and the westerlies


    equatorial currents shift, causing trade winds to shift

    warm water drives east, causing drought, fires, precipitation anomalies, and ecological misalignment

    upwelling stops, preferable off the coast of Peru for fishing

    severe event in 1997/8

    La Nina

    current moves in opposite direction of El Nino


    solid earth material that has been altered by physical, chemical, and organic processes so that it can support rooted plant life

    factors of soil formation

    S = f(cl,o,r,p,t) cl = climate o = biota r = topography p = parent material t = time soil horizons

    over time soil formation creates soil horizons

    differing physical characteristics

    generally 3/4 present


    processes that break rock down into soil (precipitation & chemical processes)

    tropical soils are highly weathered

    partly b/c of rain leeching nutrients

    nutrients come from compost (rapid decomposition occurs)

    Cation Exchange Capacity (CEC)

    tropical soils have low CEC

    soil organic matter has high CEC

    clay, silt, and sand have low CEC

    capacity to attract positive ions (ie nutrients)

    Al is unattractive cation

    tends to dominate anions

    soil texture determinants

    clay, silt, and sand

    oxisols highly weathered

    rich in iron and aluminum oxides

    very low fertility

    shallow or no "O" horizon

    low organic composition

    8% of global ice-free land area

    most common tropical soil types

    oxisol, ultisol (dominant in SE Asia), entisol (common in deserts, doesn't save nutrients)

    all tend to be reddish-orange

    Net Primary Productivity

    measure of amount of green matter

    net amount of carbon uptake

    litter decomposition

    warm, wet, and productive

    characterizes lowland tropical rainforests

    What is NPP and how does it relate to drought? (Vogt)

    Net Primary Production, or NPP, quantifies both the amount of energy pooling in an ecosystem and the energy flowing through. NPP can be an indicator of the links between social and ecological systems. The value also infers the adaptability of individual species to a change in environment. NPP is being used in this study to indicate whether the impacts of drought affect how much biomass is produced and how many resources are extracted via ecosystem services.

    2. What is the motivation for this study? (Vogt)

    Vogt et al. attempts firstly to determine the impacts of climate change on the "coupled human and natural systems." More specifically, the study investigates whether soil textural-class levels determine the NPP post-drought, which will provide some idea of which sections of forest are most vulnerable to climatic extremes. The results of the research have implications for the forests susceptible to drought and the communities (both ecological and social) reliant on their resources.
