Answers (100% Correct Answers) |
Already Graded A+
what are gradients other than temp that might be important in influencing
the response functions and distribution of organisms - 🧠 ANSWER
✔✔moisture, light, nutrient, pH
fundamental niche - 🧠 ANSWER ✔✔a larger area or range indicating the
potential conditions and resources a species can use if there are no limiting
biotic factors
realized niche - 🧠 ANSWER ✔✔smaller subset within the fundamental
niche, indicating the real world conditions and resources the species uses
in the presence of biotic constraints
how can species coexist in multiple niche dimensions - 🧠 ANSWER ✔✔by
occupying different parts of niche dimensions, thus reducing direct
competition. ex resource partitioning: different species might utilize different
food sources or forage at different heights in a forest

, what is traditional ecological knowledge - 🧠 ANSWER ✔✔knowledge of the
natural environment that has developed in the course of a community's
long term residence in a specific ecosystem
how can plant species coexist through facilitation - 🧠 ANSWER ✔✔this
interaction can help plants coexist by mitigating harsh environmental
conditions, improving resource availability, or providing protection from
herbivores or pathogens. ex nurse plants that offer shade for other plants
or mycorrhizal fungi which extends the root system of other plants
3 key drivers of biodiversity loss in grasslands - 🧠 ANSWER ✔✔agricultural
expansion (crop production/grazing), urbanization and infrastructure
development, invasive species, climate change
3 biotic edge-effect phenomena associate with fragmentation in tropical
rainforests - 🧠 ANSWER ✔✔altered species composition (invasive species,
floral changes), increased predation and herbivory (easier access to prey,
more light), changes in pollination and seed dispersal
3 abiotic edge-effect phenomena associate with fragmentation in tropical
rainforests - 🧠 ANSWER ✔✔microclimatic changes (higher temp and lower
